Finding the right Carrier Air Conditioner for you

Residential air Conditioning can be both a welcome occasional relief or vital survival equipment based on where a home is located.  There are a number of styles, models and companies to choose from when considering a home air conditioner. The choices are almost overwhelming.  However, this is why calling a certified HVAC dealer will be the first and best decision a homeowner can make. This article will be focusing on the Carrier brand of air conditioning equipment and how they operate in general.  Carrier Air Conditioners have a very interesting pedigree. In fact, Willis Carrier invented the first modern air conditioning system in 1902. Since then, Carrier air conditioning has transformed the world we live in. The economy has benefited greatly from the introduction of Carrier air conditioning.  Suddenly, every business from manufacturing to food service was improved through the advent of air conditioning. However, residential air conditioning, which grew out of that initial invention, would be even more transformative. Willis Carrier, along with six other engineers, was able to bring to market a product which would have a profound effect on our country as a whole.  With residential air conditioning, areas which had been sparsely populated, were now inhabitable. Before long, residential air conditioning would be nearly ubiquitous. There aren’t many homes in the United States without some form of air conditioning. Carrier is still a primary supplier of a wide range of HVAC equipment both here and internationally. Most of us don’t pay particular attention to the operation of our air conditioners. 

We simply turn them on and enjoy the cooling relief that is refreshing cool air on a hot day. Many of us care for our air conditioners properly by having them serviced regularly by qualified, professional HVAC technicians. There are other HVAC related tasks we also perform like changing the air filter or unclogging the drain line. But, I would safely guess that the majority of homeowners and renters don’t know much beyond that. Carrier provides 3 types of air conditioning to its residential consumers.  The first and perhaps most popular is the Split System Air Conditioner. This type of air conditioner would be what many of us refer to as a Central Air unit. A Split System is an air conditioner with an inside component and an outside component. They are connected to one another by copper tubing containing the refrigerant. Resting outside on the concrete pad, is the outdoor unit which houses the compressor and the condenser coil. Conversely, the indoor unit (often referred to as the cold side) includes the fan coil, the evaporator coil and an air handler.  The air handler is fairly recognizable to all of us as is the outdoor compressor. Carrier also provides a Packaged Air Conditioner. This type of air conditioner can also be considered a central air unit. This is an all in one solution for homes which have very limited space both inside and out. The Packaged System has all of the components of a Split System contained in one unit. They are also ideal for use where rooftop air conditioning installation is preferred. Lastly, Carrier provides a Ductless air conditioning system. The Ductless system is aptly named because the major difference is how it delivers cooled air. This system doesn’t use ducts to transfer treated air.  Instead it has an indoor unit which contains the blower fan and the evaporator coil. This indoor unit can be attached to a wall, ceiling of even the baseboard. However, most Ductless indoor units are mounted high on an exterior wall. It is then attached, by copper tubing, to an outside unit containing the compressor and condenser. The Ductless air conditioner would not, however, be considered a central air unit. The Ductless air conditioner is meant to cool the room where it is installed. However, there can be several indoor units connected to the outside unit. This offers the ability to cool certain rooms throughout the home. No matter which type of air conditioner one chooses, the operation of the air conditioner is just about the same.  The indoor unit cools the warm air inside while absorbing heat from that inside air. It’s then sent to the outside unit where it is released. But how do all of these components work in unison to provide cool air for a home? It all starts when the thermostat senses the air needs to be cooled. This sends a signal to both the inside and outside units to begin working simultaneously. The fan contained in the inside unit pulls the indoor air through a return duct. The fan then blows it across the cold evaporator coil. The liquid refrigerant inside the evaporator turns to gas at this point. It is then able to absorb the heat from the inside air. This air is cooled by the coil and then transferred into the home by a blower fan.

That refrigerant, still in its gas form, leaves the home for the outside unit via copper tubing.  At this point, the refrigerant goes into the compressor where it is pressurized and sent to the condenser coil to be released to the outside air. While this process is going on, the refrigerant turns back into a liquid. In its liquid form, the refrigerant then travels again through copper tubing to the inside unit. Finally, the refrigerant goes through an expansion device which then regulates the flow of refrigerant back into the evaporator coil. The cycle then begins again and again as the air conditioner runs. Air conditioners work to remove heat and humidity from a home. This is what we consider modern air conditioning. Residential air conditioning units don’t simply blow in some sort of canned, cooled air. It is a mechanical process based on nature and physics. Willis Carrier and his band of engineers came up with what we consider modern, residential air conditioning.  The basics of how air conditioning works really hasn’t changed all the much from the first designs in 1902. However, air conditioning technology continues to evolve in order to meet the ever changing homeowners inside air comfort needs.
