What Each Component of an A/C Unit Does


Understanding how your cooling system within your home works will not only help when talking with an HVAC tech, but also helps you understand the importance of having your A/C system inspected and maintained each year to keep it running efficiently.

The technology behind cooling the most occupied rooms in our home is ingenious and simple. It’s based on using a chemical refrigerant, which easily converts from gas to liquid, to transfer heat out of your home. An air conditioner cycles the refrigerant through its system, removing heat with each cycle, until your home has reached the desired temperature.

We all know how important A/C is to our survival during the hot Phoenix AZ summers but most of us never stop to think what each main component of our units are and what each ones does. Having a better understanding of them will help you trouble shoot any future issues or at least make an air and heating tech’s explanation not seem so foreign should you have to call one out to the house.

Here are the components:

Condenser – The condenser houses several parts. It is found outside the house when it used in a central air conditioning system. You need to place it in a cool, shaded location. If the condenser were to be placed in a warm location, the machinery would have to work harder and your energy costs rise.

Air Compressor – The air compressor consists of a motor that pumps the refrigerant gas from the components inside the building into the compressor outside. This is where the gas is condensed. As the pressure rises, so does the temperature. The refrigerant gas is sent into the condensing coil.

Condensing Coil – The condensing coil allows the gas to expand and cool. Excess heat is removed by a fan that blows air across the coils to the outdoors. The cool refrigerant continues to move through the coils.

Fan – The fan is a very important aspect of the air conditioning system. Without it, the coolant would stay warm and the building would never cool. If you are having problems with your air conditioner, this is one of the first components you should check.

Belts – The motor belts should be checked regularly. If they become loose, the motor will not work as effectively and it will take longer to cool the building. The belts should always be replaced if they are frayed or cracked.

Filters – Without filters, outdoor allergens can easily pollute your home. This will cause added stress to any allergy sufferers. Filters also help reduce a home’s humidity, reducing the viability of any mold spores, making your home healthier. All the filters should be changed periodically. They also need to be cleaned. This prevents dust from collecting on the evaporator coil and encourages more energy consumption.

Thermostat – Another important element is the thermostat. This allows you to choose how cool you want your house. Setting it at a higher temperature will save you more money than setting it at a very low temperature. Be sure your thermostat also shows you the indoor temperature. This will help you asses any possible problems. You will know if it is taking to long for your house to cool down, if it becomes to cool or if it doesn’t become cool enough.
