4 Air Conditioner Maintenance Tips Homeowners Need to Know

We here at Legacy Heating and Cooling understand how important your air conditioner is to your home. This is especially true during the warm summer months, as your air conditioner puts in the work to ensure that everyone in your home is comfortable. Given this, you’ll want to make sure that you perform maintenance on it to keep it running efficiently and effectively. 

Now, we understand that not everyone has the expertise to do this. To help you out with this, we’ve put together a list of air conditioner maintenance tips. If this is something that you want to know more about, read on for our list of four maintenance tips that every homeowner needs to know.

Clean the Air Conditioning Filters

Let’s start with the most simple, yet extremely important, maintenance task: cleaning the air conditioning filters. A clogged filter restricts airflow within the air conditioner. This can cause serious damage if left unattended. To add to this, clogged filters also cause your air conditioning system to use more energy. This is why we recommend cleaning your filters at least once each season to ensure that your air conditioner is always working at its best.

Remove the Dirt from Evaporator and Condenser Coils

Aside from the filters, you’ll also want to make sure that the evaporator and condenser coils are free of dirt. The dirt reduced the airflow and insulates the coils, which prevents them from functioning properly. This will hamper your air conditioner from properly cooling your home. If left unchecked, dirty coils will also lead to compressor damage. For those of you planning to clean the coils yourself, be sure to purchase foaming sprays as they will make the process infinitely easier. Lastly, make sure that the system is off when you’re cleaning to avoid damaging your system. 

Straighten the Coil Fins

Staying on the subject of coils, you also want to make sure that the coil fins are kept straight. Defecting coils also negatively affect the air conditioner’s performance. While it’s best to leave this up to the experts, you can attempt to do this yourself. All you need to do is to purchase a fin comb and bend the fins back into the right position.

Check for Refrigerant Leaks

If you’ve noticed that your air conditioner isn’t sufficiently cooling your space, then this might be a sign of a refrigerant leak. An air conditioner system with refrigerant leaks not only causes your air conditioning system to use more energy (which will result in higher electricity bills) but also emit greenhouse gases that are extremely bad for the environment.  This is why you should constantly check your air conditioner for refrigerant leaks. If you do spot a leak, it’s best to leave it to the professionals, as refrigerant leaks aren’t something that the everyday person can fix


We hope this article proves to be useful when it comes to helping you maintain your air conditioner. As you can see, none of these are particularly difficult to do. It’s really just all about being consistent with air conditioner maintenance. If you encounter more serious issues while doing maintenance, we recommend calling on professionals to come and take a closer look.
