If you need a completely new Central Heating Air system, we can handle it from the ground up. We will calculate the square footage you need climate controlled, the amount of Btu's needed for easy living, and suggest one of the many systems we supply that best fits your needs. If you're unsure of what a BTU is, it is an acronym for British Thermal Unit (B.T.U.). Per the article on Wikipedia: "It is approximately the amount of energy needed to heat 1 pound (0.454 kg) of water, which is exactly one tenth of a UK gallon or about 0.1198 US gallons, from 39 °F to 40 °F (3.8 °C to 4.4 °C)."
The BTU is used as a calculation of Heating or Cooling Air potential. Every Central Heating & Air unit has a rating based on the BTU measurement. This allows for both the customer and installation company to figure out exactly what is needed for your home. Getting the correct BTU rating is essential in any cooling or heating application. If you have too few, the system will not be able to handle the load, and will wear out faster trying to keep up. If you have too many, then the system is overpowered and will waste energy. Energy is a resource in this ever growing world which is far too precious to be wasted,and especially, since it would be at your expense!
Speaking of energy conservation, did you know that our Central Air Heating systems will themselves save you money through less electricity usage? Not only will you reduce your dependence on the electric company by employing selective zone Cooling and Heating Air, you can enjoy the same 50% to 60% cost reduction reported by our customers!

Today, Air Conditioning Heating - Units can be classified by their ability to alter certain properties of air such as temperature, quality, velocity, and humidity. These terms can also be used to describe any conditioning of air through technology that results in heating, cooling, ventilation, or disinfection. Air - Conditioning - Heating Units can be defined as a machine, system, or appliance whose main function is to change the temperature and or the humidity of the air in a certain enclosed environment. Most of these setups use a refrigeration cycle, but can also incorporate evaporation.
Air Conditioning Heating Unitsare certainly not what they used to be. And, for the most part, that is a good thing! The origins of these Air - Conditioning Heating Units can be traced through many centuries and countless revisions. As far back as the second century B.C. the Han Dynasty was delighted with the promise of cooling by a rotary fan, invented by Ding Huan. This early device was manually powered, or for those of the technology generation who aren't familiar with this vintage tongue, it was turned by hand!
In ancient Egypt a primitive cooling system was invented which allowed some relief by hanging reeds in the windows and allowing water to trickle down them. When the water evaporated it created cooling which was drawn into the abode by a gentle breeze, although this had the adverse affect of increasing humidity. In Rome a similar Air Conditioning Heating Unit system used incoming aqueduct water to circulate within the walls of certain homes. This rather elementary approach again offered some respite from the immolating summer heats.
It wasn't until many years later, in the Tang Dynasty, circa the 8th century, that sufficient revisions had been made to incorporate these ideas into a dwelling. Within the walls of the imperial palace the Liang Tian, or Cooling Hall, was created to offer respite to the emperor on those intolerable summer days. This ancient Air Conditioning Heating Unit housed such improvements as water powered fan wheels, and fountains, each sporting a stream of jets and geysers. After this short stint of evolution, these technologies would lay dormant for almost a millennium once again.
Almost a thousand years later, Air Conditioning Heating Units would once again take a baby step forward. This time one of our founding fathers, Benjamin Franklin, paired with a chemistry professor from Cambridge University, John Hadley, to study latent heat. Through meticulous observations and grueling experimentation, the duo soon discovered they could cool a mercury thermometer to -7C, even in a warm room. This seemingly impossible feat for its time was accomplished by spraying the instrument in ether, then providing a constant breeze. By blowing on the thermometer the ether quickly evaporated and drew off the heat already present. These early forays into the study of evaporation would later lead to Mr. Hadley being elected as a Fellow of the Royal Society. Mr. Franklin, as we all know, would lead an interesting life filled with many accolades from his peers, heirs, and other descendants, and was most famous for being part of the foundation that created our unique living constitution.
Of their experimentation into the principles behind modern day Air Conditioning Heating Units Mr. Franklin was famously quoted as having said, "From this experiment one may see the possibility of freezing a man to death on a warm summer's day...". I'm sure that on some of these most recent record breaking heat wave days, one could only wish for such a demise.
This era of pre-industrial cooling would give way to advances in chemistry. As early as the 1800's, mechanical Air - Conditioning - Heating Units were invented. In 1820, Michael Faraday, who was most famous for his contributions in the fields of electromagnetism and electro chemistry, discovered a process by which one could chill air by compressing and liquefying ammonia gas, and then allowing it to evaporate. Another Air - Conditioning - Heating - Units around this period included compressor technology used by physician John Gorrieto create ice. This ice was then used in his hospital in Apalachicola, Florida to cool the air for his patients. He had grand visions for his Air-Conditioning-Heating-Unit devices, including the ability to heat or cool an entire building. Mr. Gorrie was also the first credited with being able to envision centralized Air-Conditioning-Heating-Units which would cool entire cities. While John Gorrie's ideas were monumental, his actual prototypes were somewhat less miraculous. In 1851, John Gorrie received a patent for his ice producing equipment despite the fact the it leaked badly and preformed irregularly. In the end though, his biographer, Vivian M. Sherlock, reported the Mr. Gorrie succumbed to a series of unfortunate events and died a broken and impoverished man in 1855. John Gorrie's chief financial backer passed on, and Mr. Gorrie was the subject of as mear campaign launched by one Frederic Tudor. These events lead to Air Conditioning - Heating Unit theory, design, and fabrication being abandoned again for another 50 years.
Although the formal idea of Heating Air Conditioning Units was to slumber for a number of years, there was still important work to be done in the 1850's. For instance, James Harrison created a mechanical ice making machine which began operation in 1851. This device started operation of the banks of the Barwon River in Gee long, at Rocky Point, Australia. Only a short three years later, in 1854, he improved on the Heating Air Conditioning Units idea and received a patent for an vapor-compression refrigeration system in 1855. Revolutionary for its time, this system used a compressor which forced a refrigeration gas through a condenser. This process caused the gas to cool down and liquefy. Once this step was completed, the liquefied gas then circulated through a set of coils and vaporized again which caused the surrounding system to cool down. This machine consisted of a fly wheel sixteen feet in diameter and could produce up to 6,600 pounds of ice per day! For the time, this was quite a haul!
James Harrison enjoyed commercial prosperity in the 1860's when he started a second ice company in Sydney, Australia. Mr. Harrison even penned a guide book, "Fresh meat frozen and packed as if for a voyage, so that the refrigerating process may be continued for any required period". In 1873, James Harrison embarked on preparing a sailing ship, the Norfolk, for an experimental trip. He was to use his experience with Heating - Air Conditioning Units to prepare a beef shipment for transport to the United Kingdom. Mr. Harrison would make a fatal mistake though when he decided to use a cold room for storage instead of installing the Heating - Air Conditioning Units on the ship itself. Problems immediately set in when the ice was used much faster than had been expected, and, of course, the entire shipment spoiled before reaching its destination.
This daunting mistake lead to the overall abandonment of refrigeration development once again, and it wasn't until 1902 another set of major advancements were made by Willis Havil and Carrier in Buffalo, New York. This version of Heating-Air Conditioning Units would later become our modern equivalent of electrical air conditioning. Mr. Carrier, who was a native of Angola, New York, and graduated from Cornell University. While attending Cornell, Willis, as he was known by his friends, forayed into air conditioning to solve problems for Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, New York. They were experiencing a problem with application of certain materials, and Mr. Carrier brought them the plan of using a primal Heating Air-Conditioning Unit. So, on July 17, 1902, the first industrial application use of air conditioning began operation.
This Heating Air-Conditioning Unit system was specially engineered to make improvements in the manufacturing process for the companies printing work. A major improvement that Mr. Carrier brought to this technology was to add humidity control. Willis adapted his vast understanding of the heating of items with steam and reversed the process. Mr. Carrier ran the air through water cooled coils instead of using the days standard hot coils. This adaptation allowed adjusting the amount of moisture the cooled air could retain, and therefore the over all humidity. This advantage would prove of tremendous use to keep the temperatures and humidity much lower than would be normally possible. With the printing environment under proactive climate control,inconsistencies in paper dimensions and ink alignments soon disappeared leading to a much higher quality of product.
Mr. Carriers Heating Air-Conditioning Units would be used in the workplace to increase productivity through more comfortable conditions later in his career. The Carrier Air Conditioning Company of America was formed when market demand increased, and eventually his systems found such diverse applications as residential and automotive. During the 1950's, home use became widespread and sales of the Heating-Air-Conditioning-Unit enjoyed a dramatic spike.
There was also Heating-Air-Conditioning-Unit work carried on by another person of note during the same era, and this undertaking was for industrial applications as well. Out of Charlotte, North Carolina, a Mr. Stuart W. Cramer needed a way to add moisture to the air for his textile mill. "Water Conditioning" as it was then known, was a popular method which allowed the materials used in production to be processed with added ease. Mr. Cramer has been credited with coining the term "Air Conditioning" when he used it in a patent for his devices and methods. Stuart Cramer's machines would combine ventilation with moisture to bring up the humidity in his factories. During the course of Mr. Carriers and Mr. Cramer's advances with the Heating-Air-Conditioning-Unit technology, the term "Air Conditioning" would be adopted to create the Carrier Air Conditioning Company of America.
The Dubose House, located in Chapel Hill, North Carolina was the first private home to incorporate a Heating and Air Unit for cooling. It was considered the first real air conditioning system, and was based on the principles of evaporating water into air to provide a cooling effect. This process later became known as evaporative cooling, and is in continued use in certain applications even today. This home was also the first to have an ingeniously designed system of duct work and vents, hidden away behind ornate and attractive Georgian-style open moldings.
In 1928, another major advancement in Heating and Air System technology was discovered through the use of a non-toxic, non-flammable chlorofluorocarbon gas. Prior to this time, the most efficient gases used were ammonia, methyl chloride, and propane. Unfortunately these substances were either poisonous or flammable, and even a small leak could prove disastrous if unnoticed over a small period of time. These early systems which incorporated these precarious coolants resulted in several fatalities.
This new refrigerant developed solely for Heating and Air System use became known as "Freon", and actually consisted of a range of Chlorofluorocarbon, Hydro fluorocarbon, and Hydro chlorofluorocarbon gases. Each type of freon was differentiated by listing it with an "R" for refrigerant followed by a number that represented the particular gases molecular composition. For instance, popular Heating and Air System coolants would be listed as "R-11", "R-12", "R-22", and more recently, "R-134A". Although these particular refrigerants have enjoyed a long and storied history, certain molecular weights are being phased out in favor of coolants that pose a lesser risk of environmental contamination. One of the most popular that is being done away with is "R-22", a Hydro chloro fluoro carbon solution that is banned from new equipment as of 2010, with plans for complete retirement of in-use systems by 2020.
The Heating and Air-System designs used for most automotive applications up until 1994 required a variant of Freon referred to as "R-12". Due to more aggressive restrictions on chemicals known to cause the greenhouse effect, it was decided then to replace the older systems with a more efficient variety which uses "R-134 A". The hey days of "R-11" and "R-12"came to an end, and these types are no longer even manufactured in the United States. In the rare instances that these older systems need to replace the outdated freon which has leaked over time, the only recourse is using recovered coolants from retired systems that has been cleaned and purified.
Modern automotive Heating and Air-System technology rely on the much more stable "R-134 A" variety of freon. Honeywell, a company specializing in control and cooling systems, has even developed a brand of freon which bears the mark of "R-410 A" and is known as a non-ozone-depleting refrigerant. "R-410aA" was sold under the name Genetron (R) AZ-20, and was first used commercially by the Carrier corporation under their version of the brand name, Puron, for its purported environmental benefits.
Improvements are still being made to Heating and Air-Unit systems, even as of today, with a great deal of emphasis placed on efficiency and regulating indoor air quality. Innovations which reduce the impact of climate change is a very important area of research not only because of the green house emissions related to energy production but because Chlorofluorocarbon, Hydro fluorocarbon, and Hydro chlorofluorocarbon gases are themselves a potential potent danger to the ozone layer. As an example, "R-22", also known as HCFC-22, which is one of the varieties being phased out, has a warming potential for the Earth that is 1,800 times higher than CO2. So, as you can see, even a small amount that escapes into the biosphere can have alarming repercussions.
Heating - and - Air - System technology has evolved over the years. Increased energy efficiency combined with safer coolants has lead to great advances in the comfort levels from once horrid work conditions to stifling heat in the home, and all the while becoming better for our surroundings. Still, Heating - and - Air - Unit systems continue to advance and will no doubt play a critical role in the future as we come to live with the results of the worlds wild abandonment concerning pollutants. Heating - and - Air System and related systems will provide the solace we will need as our world becomes warmer, and give us an escape from the harsh conditions we have reaped upon ourselves, and the future generations.If we are to maintain any measure of control in the future, ongoing advances in research will need to keep pace with the staggering demands of the Earth's exploding population.
Engineers whose main concern is the design of Heating and Air System have divided its application into two broad categories: comfort purposes, and process use. The demands on the Heating And Air Units system will determine which category it falls into. While the purpose of the comfort category is to provide a relatively constant indoor environment despite changes in the weather outside, the process category is suited better to creating conditions favorable to a certain process being carried out.
The advent and consumption of the comfort area of Heating-and-Air-System technology was self sustaining to a degree, with its widespread use garnering even more demand through a better ability to create "deep-plan" buildings. With out the reliable nature of the systems, buildings would have to be built much narrower, or even contain light wells. Another benefit created by this new found machinery also allowed buildings to be made taller, as natural ventilation was hampered with altitude by an increase in environmental wind speeds.
There are a great many sub divisions within the comfort category of Heating-And-Air-Units, and each has its own specialized equipment and requirements. Some of the major segments of the comfort facet are: Low-Rise Residential, High-Rise Residential, Commercial, Institutional, Industrial, and recently, Sports Stadiums. As you can imagine, each of the designs and apparatus for full filling these needs would be quite different.
One last use for Heating and Air-System considered to be in the comfort zone would be their application for use in transportation. Automobiles, buses and other land vehicles, trains, ships, aircraft, and even spacecraft owe their respective ability to control their own environment to advances in Heating and Air-Units systems.
As we've already discovered, the process application side of Heating-and-Air is better suited to creating the ideal conditions for completing a particular practice. Once again,there are a number of sub divisions when considering the correct environment and thus, a number of decisions on what exactly is needed.
For example, a simple utilization of Heating-And-Air may be the regulation of temperature around a kitchen. These areas may become very warm with all the energy expending cooking foods, and being able to maintain a comfortable working area is paramount to continued productivity and overall quality. We can all relate to being in those stifling surroundings on Thanksgiving I'm sure,but there are far more serious uses with demanding requirements. Most of these situations aren't something we consider normally, but with out their contributions, modern life as we know it would come to a grinding halt.
Mining for instance, would not be able to keep up with contemporary demand if not for certain advances in Heating and Air ventilation and cooling. Dangerous gases can built up quickly in a tunnel with stagnant air flow, not to mention intolerable heat. This again, is on the primitive side of functions provided through air conditioning and ventilation, however even this fundamental purpose has a significant impact on the world.
Some of the more serious employments of Heating-and-Air technology is in textiles, regulation of temperatures in data centers, nuclear power plants, and chemical and biological laboratories. As much of a myriad of purposes this serves, there are even more applications which would not even be possible if not for today's knowledge and understanding of the methods and practices for keeping our surroundings relatively regulated.
Hospital operating theaters is a use where the air is heavily filtered and conditioned to reduce the risk of infection. In addition to its ability to help prevent contamination problems during the surgery, moisture is adjusted to help minimize dehydration. While procedures such as open heart surgery may need a relatively low temperature in the range of 18 degrees Celsius (or 64 degrees Fahrenheit), other implementations may require a slightly high than normal climate. A neonatal care unit, for example, needs an environment in the 28 degree Celsius, or 82 degree Fahrenheit range.
Another important application for Heating And Air is its ability to provide an appropriate atmosphere for "clean rooms". "Clean room" is a term used to describe an enclosed area designed specifically to reduce dust,pollen, debris, and any other possible impediments in the air to the highest degree possible. Similar to its benefit in hospitals, these "clean rooms" are fundamental to the production of integrated circuits, pharmaceutical, and the like, where very high levels of purification are needed, combined with temperature moderation and the ability to adjust humidity. Without Heating-And-Air science we would not be able to enjoy the vast diversity of electronics, modern chemical engineering for medicine, or even simple antibiotics such as penicillin.
In addition to the a fore mentioned operations, one last assistance that these machines provide is the ability to help breed laboratory animals. Particular types of these creatures will mate and produce offspring only during certain periods of the year. By being able to simulate and maintain these conditions, new generations of young can be spawned year round providing an ample supply.
The history of Heating Air Units has been a gripping foray into advances in technology and the ingenuity of the many who have contributed to today's modern machinery. We've seen such simple uses for this industrial science as cooling a scorching kitchen, and such high tech applications as clean rooms and hospital operating rooms. To be sure, the comfort provided from this tremendous work has become a necessity in today's ever warming global climate. But what does the future hold for Heating Air Units? What advances can we look forward to seeing? Is it possible to combine tremendous efficiency with reduced power consumption to maintain our comfort in a world where spiraling energy costs are coupled with dwindling resources?
Fortunately, research and development in the Heating Air Units arena continues today. Advances in chemistry have provided refrigerants which are friendlier to our environment, thus reducing global climate change. Stronger and lighter materials have been discovered and manufactured, reducing the size, weight, and carbon footprint of the units from the ground floor. Standards, goals, and guidelines have culminated in a consensus giving a foot print for the future generation of Heating-Air Units. Is a major break through on the horizon? Is there something being developed and produced today that has potential to address not only the currently aging set of equipment in use, but the frugal demands of the future? The answer may surprise you.
As we know it today, Heating-Air Units are those clunky appliances split into two differing units:the air handler, and the compressor. The air handler, which sits hidden under the house, in the attic, or stowed away in a closet provides the means for ventilation. It draws in air from the dwellings interior, circulates it through the cooling coils, and then sends it flying through that long, dusty, and often leaking duct work to bring the inside temperatures down. We all know this as the sound of the system kicking on late on a sultry summer night to relieve us in those suffocating extremes. The second component of the Heating-Air Units system is the compressor. This machinery is the "box" that sites outside and grumbles to life when we crank the thermostat down. The compressing unit acts much in the form of a thermal exchange by drawing the warm air into the cooling coils, pumping this gas to the outside system, allowing it to evaporate,condensing it once again, and cycling this compressed gas back into the cooling coils. This process will be repeated many times as, for as long as the Heating-Air-Units system is running.
For many years now, this has been the standard in Heating-Air-Units design and installation. It wasn't until the advent of massively overpopulated cities, crowded conditions, faltering energy reserves, and a shrinking standard of living that the next revolution in this technology would appear. With cramped living quarters developing in to the norm in European countries, a new idea formed. Something that would allow each person their own level of comfort and at the same time cut down on pollution and the ever endangered free space required by large units. Shouldn't there be a way to provide the same level of cooling or heating, but reduce the size of the machinery and get rid of the inefficient, leaky, and dusty duct work and vents?
Did you know that the biggest loss of power in any Heating-Air-Units system is through it's duct work? This happens through two principles. This first is Energy Loss Through Conduction which is when the heat (or cooling energy) passes through the duct work by physical contact. Just think of it as having to heat up or cool down the entire length of duct work first, before any actual work is done to the air! The second principle for power loss in the duct work is Energy Loss Through Air Leaks. This one is fairly simple, as any damage, cracks, or corrosion to the duct work would create problems with correct air flow. If you've ever seen a car sputter of cut off due to a vacuum leak in the carburetor or fuel injection system, you can easily imagine the effect on your cooling system.
Imagine the energy conserved if this device could produce the warmth or cold chill at exactly where it was needed. Not only could the Heating-Air-Units perform much better, a significant savings in electricity and resources could be realized. At the same time, the overall atmosphere of the area being conditioned would improve simply from the removal of the contaminants which gather in duct work,and circulate through the environment when the system is powered on.
Air and Heating fortunately have now evolved to the point where new advance scan be engineered into the systems. One of the major new breakthroughs is the removal of the duct work. Through a system known as a ductless mini-split, the actual Cooling and Heating Air part of the unit is placed where it is most needed, eliminating the dusty, expensive, and cumbersome ducts. By reducing the overall foot print of the machinery, energy is used more efficiently and instead of being dissipated in the long paths through those snaking metal tubes the cooling or heating is dispensed exactly where it is needed.
This Air and Heating design has a definite advantage in power conservation, but are there more benefits? Certainly! Another plus of using this set up is zone Cooling and Heating Air. For instance, you can cool or warm just the most used rooms in your home, instead of wasting those valuable utility dollars providing a controlled environment where it is least needed. Another extra provided by these types of Air and Heating systems is the ability to combine the outside compressor for use with multiple indoor air handlers.
Using a multiple air handler system in conjunction with the ductless advances in Air and Heating allows sets of rooms to be cooled. Each of the indoor handlers can heat or cool up to two rooms on their own, so even with a simple one condenser unit, and two handlers, you can still provide comfort to most of the home while realizing tremendous resource conservation.
A very important aspect of Air and Heating is their ability to maintain humidity control. Does the ductless system afford these same qualities? To understand why humidity is important, one has to know about the basic cooling principles of the human body itself. Our simplistic physical forms perspire creating a light sheen, or droplets of sweat on our skins.
This liquid evaporates from the flesh, and as it does, it draws heat out of our body. As this vapor pervades our surroundings, it saturates the air. By using a system which regulates the removal of this added moisture, comfort in the living quarter can be greatly improved.
Most modern Air-and-Heating these days perform the functions of a humidifier or dehumidifier in addition to providing Heating and Cooling Air. In normal operation, this would be mostly to remove excess moisture. By removing moisture, the levels in the environment drop and this allows our bodies more freedom with its cooling measures. It has been discovered that a relative humidity of 40% to 60% seems to provide the best level of comfort. Much like a glass of ice water condensing vapor from the air, some food retailers experience the benefit of large open chiller cabinets, which act as highly effective air dehumidifying units.
So what is a dehumidifier? It is a very specialized Air-and-Heating designed specifically for removal of moisture vapor only. Unlike typical systems, a dehumidifier contains both the evaporator and condenser coils together, which are arranged for a particular air flowpath. Also dissimilar to a normal unit, the entire device is enclosed in one casing versus having an indoor air handler, and the external compressor element. The dehumidifier works by drawing the air first past a cooling coil, where the moisture condenses. This water is collected to be removed later, or pumped out through a series of pipes. After this vapor has been removed from the air to be conditioned, it is then passed by a heating coil. This warms the air back to ambient temperatures, albeit much drier than it was before.
Another interesting principle at work behind the scenes when a Air-and-Heating is set up as a dehumidifier is its ability to warm a room with the same efficiency as a comparable wattage portable electric heater. Since the dehumidifier is setup to operate in an enclosed environment, the area to be conditioned becomes a thermodynamic system. While normal Air & Heating drain environmental energy out of the atmosphere to provide cooling, a dehumidifier transmits the energy it uses into the inside setting. This electricity usage is felt as heat, and is the exact opposite of adding water to the room through evaporative cooling.
Air & Heating that are set up as dehumidifiers are usually employed in cold, damp areas where mold growth is expected or present such as basements. Another very beneficial use of a dehumidifier is to protect sensitive and scientific equipment from excessive moisture where it can pose a significant risk of damage. Other areas of application include clean rooms and surgical theaters to reduce the chances of contamination. Indeed, many mission critical and modern conveniences are based on both the cooling systems, and their ability to maintain a comfortable moisture level. They also contribute in numerous ways to the fabrication of electronic circuits and other materials which, for the most part, we take for granted in the hustle bustle of everyday life.
When considering Central Air Heating and Cooling systems and their replacements, it is important to know the specific needs of the area to be maintained. Although the formula's for calculating the required energy usage for a particular comfort level can be extremely complicated, certain methods have been developed to help the end user make informed choices. There are a number of ratings that have been developed by the Air Conditioning, Heating, and Refrigeration Institute, in its publication AR210/240, which allow us to gauge a certain system.
A BTU is an acronym for a British Thermal Unit. It is a measurement of the amount of energy needed to heat one pound of water by one degree Fahrenheit under normal atmospheric conditions and pressure. Although formally the unit is a measure of heating power, it can be used for determining cooling efficiency in that the Central Air Heating and Cooling system is rated by its ability to remove heat as counted in Btu's. Both the SEER capacities and the EER quantities are expressed as a ratio of BTU removed per hour divided by the amount of electricity needed, in watts. This is contrary to the Coefficient Of Performance, in that its ratio is counted solely in wattage and can be applied universally. The COP is a description of the relationship between the amount of energy needed and the amount of work done. For instance, a COP rating of 2 could actually be represented as 2:1, or 2/1. This simply means that for everyone unit of energy used, 2 units of work is accomplished. The higher the Coefficient Of Performance, the better the unit uses its input power.
Whereas the COP can be used to describe any enclosed thermodynamic system, the Energy Efficiency Ratio is more apt for Central Air Heating and Cooling systems. It is an expression of efficiency based on the cooling power provided in Btu's per hour divided by the input electricity in watts. Basically, it shows how much cooling you receive for the amount of power consumed. This is an important quantity to understand as the higher the rating, the better the unit is at using electricity. A lot of times, you will see this listed on energy star labels and consumer information guides.
The Seasonal Energy Efficiency Ratio, or SEER for short, is also an important Central - Air - Heating and Cooling measurement. Much like the standard Energy Efficiency Ratio, the SEER is also a method for determining the units relative cooling power. The SEER however, is adjusted to an annualized basis. This allows the user to see the usage and output of a particular unit over an entire year which is useful in visualizing the seasons need, and potential cost over a longer stretch. While some Central - Air - Heating and Cooling systems provide better efficiency over a short term, knowing the SEER number can be helpful for continued use or more intense applications.
Most Central-Air-Heating and Cooling of today, even though vastly improved from the machinations of history, come no where near the theoretical maximum SEER or EER rating. Only limited by the laws of thermodynamics, this ultimate efficiency is referred to as the Carnot cycle when dealing with refrigeration processes. The Carnot cycle, while not immediately important for the end consumer, is important for those designing and manufacturing Central-Air-Heating and Cooling equipment. It is based on a different temperature scale beginning at absolute zero, and uses the fundamental range of temperatures being heated or cooled. Its calculation would start with knowing the desired goal, and the thermal condition of the exterior climate. Solving this calculation will give the system engineer a general idea of the units aim and somewhat of a notion needed for its efficiency.
By settings standards for Central-Air-Heating-and-Cooling systems, the consumption of our valuable resources by the population can be moderated to a acceptable degree. In fact, many governments including the United States of America, now have minimum allowable ratings for the manufacture of modern machinery. With these guidelines the older Central-Air-Heating-and-Cooling units being replaced are assured to provide the most comfort for the least cost, and reserve those valuable energy stores for the generations to come.
Central Heating and Air unit construction comes in many forms, but most all are based on the use of a refrigerant. Over the years, different compounds have been developed solely for this purpose. In the beginning these solutions were based primarily on their ability to provide the best cooling ability. As time progressed, it was discovered these chemicals have a negative impact on the environment through depletion of the ozone layer. Later on, through advances in chemistry most of the primitive refrigerants in Central Heating and Air systems are being phased out with more globe friendly substances. For instance, the predominate coolants used today in residential applications is R-22. This is a replacement for R-11, or R-12, which were more common in the past, and determined to have severe volatility in the upper atmosphere due to ultraviolet cleavage of the chlorine-carbon bond. This in turn, causes the creation of a chlorine radical. Oxygen, as it appears in nature, is broken down by percentages of diatomic molecules, meaning two conjoined atoms, and ozone, which is a small percentage of the overall volume, and consists of three melded Oxygen atoms. The chlorine radical produced by cleavage from the sun's radiation, is a strong catalyst for breaking down ozone into the basic diatomic oxygen, and greatly speeding depletion of this protective layer.
Because if the tremendous demand today for Central Heating and Air equipment constant upgrades are being made in the technology, as well as research and study into the chemistry behind refrigerants. Central-Heating and Air units come in a variety of configurations and size, each with its own specific use. The most basic of appliances is a packaged terminal air conditioner, or PTAC. You can think of this as what you would normally see in a hotel room, or in modern apartment building. This type of unit has a through wall setup, with vents and heat sinks both inside and outside of the dwelling. Standard sizes for the PTACs are 42"×16" inches 36"x15"inches, and 40"x15" inches.
Most of the packaged terminal air conditioner type of Central-Heating and Air systems are engineered to provide the required Heating or Cooling Air using electricity only. There are however some marketed systems which provide heating through the use of natural gas, or a hydroponic heating coil. PTAC's are commonly installed in walls with windows or masonry walls and come in capacities from 2 kilowatts to 5.5 kilowatts. The former provides 7000 Btu's per hour, while the latter can perform at 19,000 Btu's per hour.
Another important type of Central-Heating and Air system is the evaporator cooler. Sometimes referred to as a wet air cooler, a swamp cooler, or a desert cooler, these units are based on the principle of water evaporation. These units are better suited for extremely dry environments and function by drawing the hot, dry air through a moisture laden pad. While these Central-Heating and Air systems appear to work best when there is an abundance of very dry air, their output can diminish when the humidity spikes. These evaporator coolers rely on the air being drawn into the house through the cooling pads, drifting into the dwelling, and forcing the warmer air out through an exhaust. This type of cooler costs less and is easier to maintain due to its simple nature.
A heat pump is a Central-Heating-&-Air setup where the refrigeration cycle can be reversed. These are sometimes marketed as "reverse cycle Heating & Air Conditioners" because instead of drawing warmth from the interior environment and pumping it outside, the unit draws warmth from the outside and cycles it indoors. These units can be very frugal in milder winter climates where the temperature range is normally between 40 and 55 degrees. However where harsher climates are present, they seem to falter when the outside coils begin to freeze over with ice. These Central-Heating-&-Air heat pumps are installed in combination with more traditional forms of heating,such as an oil furnace or natural gas where necessary. Some of the more expensive window units will actually incorporate a heat pump type setup, although not all which have a "heat" setting actually have this feature.
Although these Central-Heating-and-Air systems are the most common,they are by no means all inclusive. There are industrial applications to consider as well as usage in technical processes and hospital settings where particulate contamination could be a very real danger.
Central Heating Air has become a fundamental technology in our everyday lifestyles. Indeed it has found such ubiquitous applications outside the home as automotive, commercial, industrial, scientific, medical, and even in the athletic industries. Most modern day stadiums are even equipped with Central Heating Air units. But what happens when these units begin to age, and it may be time to consider a replacement? Is it causing problems? Pumping out hot air and nothing cold? How do you determine if it has come to the end of its life cycle? Is now the right time to spend the extra money and get a completely new installation, or would that money be better spent repairing the existing system, and hoping it will hold out a few more years? In this short article, we will answer those and other questions, and try our very best to help you figure out if repair or replacement is right for your situation.
What do you start with when making the decision to retire that old Central Heating Air? The first thing you want to find out is when the system was first installed. Typical systems today are designed to last between 12 and 18 years,however this is by no means all inclusive. Some systems still functioning today have lasted many years longer than this general guideline. Many factors can influence the lifespan of your system, including location, use of the system,and how often maintenance is performed. Quite obviously, if a system is put to work infrequently, it will last much longer then a system that is under a constant load. So, using age as a baseline, you can see that if the system is going on 10 or more years, it is probably getting close to the time it should retire to appliance heaven. However, if the system is relatively young,prudence may dictate calling for that repairman to spend some good quality time with the unit.
Most important, excluding age, is the overall performance of the Central-Heating-Air machinery. Is it maintaining its cooling power, or has it lost that once chilly feeling? Have you had repairs in the past, which don't seem to last, and keep popping up? These factors may be an indicator for replacement. Is this the first time you've had problems with the Central-Heating-Air, and does it keep the home nice and cold, or toasty warm? If so, there may be a strong possibility that you will derive many more years of adequate service from the technology. Considering only these two items can give you a good idea of where you need to go, but there are still a few other item which can help in the decision making process.
Cost of the operation of the Central-Heating-Air system is also important when making the choice of repair or replacement. If the unit is on the older side, there is no doubt that it has a lower Seasonal Energy Efficiency Ratio, or SEER rating. This measurement expresses the electricity consumption of contemporary Central-Heating-Air machines for an entire season, and the higher the rating, the more efficiently power is utilized. Newer models, through use of more advanced chemistry and updated manufacturing processes have been able to accelerate the conservation curve. With replacement of the elder systems, a significant savings in electricity cost can be achieved, upwards of 50% if the Seasonal Energy Efficiency Ratio of the new unit is close to one half the rating of the previous equipment.
Not only does the cost of operation of the Central-Heating Air affect the process, but there pair expense can be a deciding factor as well. For instance, even minor repairs to the Central-Heating Air units motor capacitor can run into the hundreds of dollars. Anything more serious, or even the need for recharging the refrigerant, can easily toss the expenditures into the thousands.
One last item to consider is how often the Central-Heating Air system is actually being used. If you live in a temperate climate where the unit is seldom engaged, then even an expensive repair may be warranted over replacement.
Hopefully this short explanation has provided some help on the pathway to making your choice to replace or simply repair the faulty units you may be living with now. As you can see, there are a number of things to consider and each situation is different. What may be good for you may not be the correct solution for others, and what may be appropriate for others, may be fiscally irresponsible on your part.
Some interesting figures related to the ongoing use of typical Central Heating & Air units are directly related to the power bill. If your average electricity consumption per month puts you at spending about twenty five hundred dollars per year, you are right there with the typical family home. Did you know that a whopping forty four percent of that amount is spent exclusively on running the Central Heating & Air? For those handy with arithmetic, you'll see that's a tremendous eleven hundred dollars! Is there any simple steps a home owner can take to alleviate some of that sizable expenditure? Actually there are, and we will cover those each in this energy saving summary.
A major Central Heating & Air condition which can contribute to increased operating costs is a dirty coil. This one item alone can drag the electricity bill up by an astounding thirty percent! Cleaning the Central Heating & Air systems clogged and dusty coil is a relatively simple maintenance to perform, and there are quite a few online articles which explain in detail how to go about this. There even is possibly one for your particular make and model of system, so you can have exact plans. We recommend viewing several different articles or videos so you can see the different steps taken by different individuals, and gain a greater understanding of the procedure. You can grow your knowledge greatly by listening in on the methods chosen by more than one person and creating your own meld of ideas.
Another important factor which can contribute to a loss of energy in the Central-Heating & Air system is something that plagues a large amount of homes spread through out America today. If an old or outdated thermostat controls your Central-Heating & Air a significant sixteen and one half percent of your yearly electricity utility bill can be wasted. By installing a modern digital and programmable controller, and maintaining the correct settings, you can eliminate this unfounded loss.
In a dusty environment or where particulate matter is particularly intense due to natural circumstances, the Central-Heating & Air conditioning systems air filter can become overburdened and clogged very quickly. Amazingly, this small item can contribute up to five percent of the total electricity usage. By simply changing out the air filter for a new one each month you can cut down on this draw on the system.
Annual tuneups through a licensed and bonded Central-Heating & Air technician is also an important issue to consider. Numerous studies have shown that over its lifetime, your Central Heating & Air system can lose approximately five percent of its capacity a year. Over the course of its normal fifteen year life cycle, this loss can compound and leave your unit operating at only thirty percent of its designed capacity, or even less. In contrast, a system that is regularly maintained can retain up to ninety five percent of its original performance rating!
These four items alone can amount to a significant drag on the operating conditions of your system. With a little elbow grease, determination, and the knowledge supplied here and elsewhere on the internet, even the most novice property owner can seek out the last and best vestiges of use from an aging or underpowered machine. By following the fore mentioned steps, you have the chance of extending the life time and lowering the electrical costs of your particular technology.
So, as you can see, there are some rather simple Central Heating & Air upkeep that the typical home owner can perform on a regular basis which will vastly improve efficiency and longevity of a particular unit. We hope this article has shed some light on the things you can do with out major expense to extend your systems lifetime. While these tips and tricks should come in handy, there never the less comes the time when it is appropriate to replace your unit. If you have exhausted the guidelines listed here, and the machinery is still not up top ar, or not providing the needed Cooling or Heating Air we have all become accustomed to, it may be time to consider that replacement. In the long run,the cost expenditure of doing a new installation will pay for itself in resource conservation, and most defiantly in your comfort level.
If you have ever wondered how Central Air Heating is used differently in separate parts of the country, and even in the world, then this short brief should be of great interest.
Central Air Heating itself is extremely common, but due to different environments and climates across the world, its use can vary greatly. One would suspect that in the northern reaches, the Central Air Heating is used primarily for heating, and you would be correct. Because these zones are closer to the north pole, and farther away from the equator, they generally get less of the suns warming rays as the earth transverses the heavens. This in turn,means less heat in general, but also less sunlight. Many of the farthest points could not even be settled if not for some form of Central Air Heating to provide the life sustaining temperatures all humans need. Think of trying to survive, or even explore areas around the north pole, where temperatures can range from negative forty-five degrees Fahrenheit, in the depths of winter, to just about freezing right around the peak of summer. With an average warmth of negative thirty degrees Fahrenheit, it is easy to understand the need for protection.
In contrast, many of the areas around the equator suffer from exactly the opposite problem, excessive heat. The equator, is of course, the point halfway between the north pole and the south pole which separates the Earth into the northern hemisphere and the southern hemisphere. And, of course, Central-Air-Heating use reflects this fact in that it is used primarily for cooling in these zones. There are a few notable exceptions however. For instance, even though a location may lie exactly on the equator, if it is of a high enough altitude, it can still be rather chilly. Think of a snow covered mountain in the tropics. If you are lucky enough to live around such an area, then you can see how the Central-Air-Heating system can be used for both purposes.
There are also a few other contrasts between strictly northern climates and southerly climates Central-Air-Heating system use. For instance, in the north, some older homes may not ever have or need cooling, and can supply their needed heat with indoor fireplaces. In these cases, the system may be a heat side supply only, running from such natural resources as natural gas, coal, or liquified petroleum. The opposite is again true for homes and buildings in the southern areas. They may never need a tremendous amount of heat, but rely on the cooling abilities of a given Central-Air-Heating unit to provide that much needed relief from external temperatures during those long, sultry, summer days and evenings.
Other important uses of Central-Air-Heating units are easily observed when considering such things as greenhouses, plant nurseries, work places, public transportation, and automobiles. If not for the climate controlled environment in a greenhouse or nursery, we would not be able to keep up with the demands for consumer foods and ornamental plants. Many of our food items are started early in the growing cycle in those indoor spaces which allow a bigger crop and a more robust harvest, as well as letting us produce year round. This advantage alone helps keep up with the worlds ever growing massive population, and cuts down on the need to plow and sow additional farmland. With natural, free, open range land constantly getting closer to becoming an endangered asset, it is very important to reserve what we can for the future generations as well as keep up with the demands on basic sustenance.
With out a doubt, Central-Air-Heating units in the work place are not merely a convenience, but a fundamental need for today's ever worsening global climate. While these systems provide comfort in the labor areas, it also promotes higher worker output, and increased efficiency. If employee comfort and happiness, and adding to the ability to produce were not enough for a particular company, some of these systems are also an integral part of process control when manufacturing many important products. If not for the ability to maintain control over the ambient temperature and particulate matter trapped in filtering systems, there would be no semi conductors (computer microprocessors)produced, film technology would still be in its infancy, and even items such as a computer hard drive would be near impossible to create.
We've taken a grand look into the history, manufacture, and use of most conventional Central air and Heating systems on the market today. As a last item of interest, one thing we have not gone into considerable detail is the application of Central Air and Heating technology in larger scale applications with large, open areas such as a schoolroom, auditorium, gymnasium, or theater. Are there different principles involved with upkeep of this environment type? Is there separate equipment designed especially for these purposes? Who helped create these wonderful machines that regulate the temperatures so well?
Central Air and Heating of today is the combination of tremendous amounts of work by a variety of chemists, engineers, and fabricators. In fact, HVAC technology,as it is sometimes referred to, is a major sub category of mechanical engineering. These Central Air and Heating systems are based on the principles of thermodynamics, fluid mechanics, and heat transfer and are a major consideration in the design and construction of large buildings. Some major contributors to our modern day machinery are Nikolay Lvov, Michael Faraday, Willis Carrier, Reuben Trane, James Joule, William Rankine, and Sadi Carnot.
Even as far back as 1899, the inclusion of Central-Air-and-Heating in larger buildings was a primary concern. One principle developed at that time was the ventilation of the area to be heated or cooled by using a down draft system. Sometimes called impulsion, or the 'plenum' principle, this Central-Air-and-Heating system worked by forcing the cooled air, at a high speed, directly at the ceiling from vents located close to the top of the walls. Thermodynamic law dictates that cold air falls, while warm or hot air rises. By pumping the cooler air towards the top of the room,we can cool a wider area as is descends and simultaneously force the already rising warm or hot air out through another set of vents located even closer to the ceiling. This technique allows a good recirculation rate for the entire area to be maintained. This also reflects another principle, that of pressurization. Since the room is constantly being filled with newer colder air, which is dense, the old stale warm air that is considerably lighter is forced to the areas of lower pressure, being the outside environment.
Of major importance in any Central-Air-and-Heating unit or system designed for larger buildings is its ability to create and maintain ventilation. Ventilation is itself the method whereby inside air is changed or replaced to condition temperature, or remove any number of pollutants including, but not limited to,smoke, heat, dust, bacteria, odors, or moisture, and then to restore a proper oxygen level. Ventilation is the single most important aspect to creating an acceptable indoor environment, and can be subdivided into its two major categories: Mechanical and forced ventilation, and Natural ventilation. Most contemporary Central-Air-and-Heating use forced ventilation in their respective air handler units, however, natural ventilation has several advantages when dealing with the spread of certain bacteria or diseases, in particular, tuberculosis, the common cold, influenza and meningitis can all be reduced by simply opening a window, a door, or using a ceiling fan. If not for the advances in ventilation and the ability to continually generate a supply of clean natural air for sick patients there would be an additional tremendous load on the already over stretched medical field.
As you can see, there are some major differences in Central-Air and Heating created for home use, and those systems which are designated for use in large rooms or conventional skyscrapers. Central-Air and Heating has become a necessity in many areas and applications, and is constantly being worked on and improved for our mutual benefit. Some of our most intrinsic technology is based on or created with the use or the advantage of these systems, and as we go into the future with an ever worsening global climate, it is important to dedicate research time and funds to continued advancements. Hopefully, this article has shed some light on the differing applications of this important field, and has answered more questions that it raised.
