Air Conditioner Parts 101

Air conditioning units in a row.

Air conditioner parts enable you to enjoy cool air on a hot summer day. To keep your air conditioner in top shape, it is important that you know the different parts and how they work. The following will provide you with a list of parts to help you understand your air conditioner better.


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 electricity bill would 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.


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 down. If you are having problems with your air conditioner, this is one of the first components you should check.


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.

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.


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 too long for your house to cool down, if it becomes too cool, or if it doesn’t become cool enough.

Replacement parts can be purchased from many different suppliers. Be sure you buy parts that are compatible with the air conditioner’s brand and style. Do not buy cheap parts just for the sake of cost. Be sure the parts you buy will last a long time.

This will save you money in the long run. If you choose to replace the parts yourself, follow the owner’s manual exactly. It will not do you any good if you find out you need to hire a professional to fix the problem again later.
