We understand that air conditioning problems can be very frustrating, especially when they happen in the middle of summer. We’ve found that a lot of people don’t understand how important proper air conditioner maintenance is when it comes to cooling issues. Here are some problems that can easily be prevented with regular air conditioning unit maintenance.


This may not seem like a big problem, but an inefficient air conditioning system can become very expensive very quickly. Making sure an air conditioner is working efficiently can save a lot of money, and can even prolong the life of the appliance. A dirty filter can greatly impact efficiency, so filters should be changed at least once a year, if not more often. The coils inside the air conditioner should also be cleaned yearly. Dirt can collect on the coils and reduce the amount of air they are able to cool, causing the system to be very inefficient.

Frozen Coils

Another reason to keep the coils and filter in the air conditioning unit clean is to prevent the coils from freezing up. This happens when there is a problem with airflow through the coils, which can be caused from dirty air filters. This can sometimes also be caused by low refrigerant levels. These coils are routinely cleaned and checked when a professional performs maintenance on an air conditioning unit.

Leaking or Low Refrigerant

One of the worst problems that can happen to an air conditioner is low or leaking refrigerant. Refrigerant is what helps cools the air that travels into the home, so low refrigerant levels mean the system won’t work as well. Low refrigerant can also cause great damage to the compressor, which is made to work with normal fluid levels. When a compressor burns out, the whole air conditioning unit has to be replaced. A refrigerant leak is something that can easily be caught with regular unit maintenance.

Thermostat Problems

Thermostats sense the air temperature and tell the air conditioner when to turn off and on. A thermostat that isn’t calibrated correctly can cause the air conditioner to run unnecessarily or cause other minor problems. When maintenance is performed on an air conditioner, the thermostat is calibrated to make sure there are no issues.

We recommend having regular maintenance performed on your air conditioning unit. This can prevent a lot of problems, including a burned-out compressor or frozen coils. Maintaining the unit by keeping it clean and the filters changed can also prevent it from becoming very inefficient and having other issues, like frozen coils. Regular maintenance can prevent thermostat issues, and help homeowners save money in the long run.
