Air Conditioning Maintenance Checklist

With another chilly winter behind us and spring in full swing, it’s time to remember that the hot summer months are on the way. One of the most important things that makes those hot days bearable is a well-functioning air conditioning unit in your home. After all, what’s better after a long day at work than entering your home and feeling that nice, cool air when it’s hot and humid outside? We hope that your air conditioning unit is working like it should, but it won’t be a long-lasting, reliable unit if you don’t properly maintain it on a regular basis. With this in mind, we’ve put together an air conditioning maintenance checklist for you as well as some other AC unit information that will keep you comfortable in your home when it gets hot this summer.

In order to ensure that your air conditioner is energy efficient, working the way it should, and keeping your home cool is crucial when it’s hot outside. One of the best ways to make sure that your AC unit works and has longevity is regular maintenance. Here are some of the important things to regularly check in order to ensure this:

Check and Clean Condenser Coils

Condenser coils remove heat from refrigerant. They need to be inspected and cleaned on a regular basis in order to maximize efficiency, prolong the unit’s life, and properly cool your home.

Inspect and Test Relays, Contactors, Controls, Starters

Your AC unit is made with many sophisticated parts. All of the main components need to be checked and tested to make sure the unit is working like it should.

Inspect Refrigerant Charge and Fix Leaks

Refrigerant is critical to the cooling process and it’s important to make sure it isn’t leaking and it’s properly charged.

Air Filter Inspection and Replacement

A clean air filter is an important part of your AC unit, and it’s important to make sure it’s replaced if dirty. This leads to a much more efficient air conditioner.

Inspect and Clean Condensate Drain

Your air conditioner’s condensate drain line gets rid of water that is released when the evaporator in your unit converts the refrigerant to a gas. Dust, algae and other things can plug up the drain line and it won’t work like it should.

Clean, Lubricate, and Inspect Motor

There are many components of the motor that should be inspected and lubricated so the AC unit’s motor continues to work properly.

Check all Belts and Pulleys

It’s important to make sure all of the belts and pulleys within the air conditioner are not worn out and working correctly.


If you happen to find that your home isn’t cool and there are some issues with your AC, there is some quick troubleshooting you can do, including checking fuses and the circuit breaker if the AC unit isn’t going on. If you find that your AC unit is on but not cooling your home, then check the air filter to make sure it’s not dirty and clogged. You can also check and make sure the refrigerant level isn’t too low or leaking.


As we put another winter in the rear-view mirror and look forward to a warm summer, it’s important to properly maintain your AC unit so that it works the way it should. Not only will you and your family have a nice, cool, comfortable home, you’ll also save on monthly energy costs with an efficient, properly working air conditioning unit.
