Why Is Regular Maintenance of AC Refrigerant Important?

Jan 03, 2016

Air Conditioning

Your air conditioner has an essential job — move the heat from inside your home to the outside, thereby cooling the house. Many moving parts make up the elusive air conditioner unit, and one of these components is refrigerant. The refrigerant plays a critical role in cooling the air in your home. Thus, annual maintenance is vital. Read on to learn what refrigerant does, and how often you should get your air conditioner’s refrigerant levels checked and serviced.

What Refrigerant Does

Simply put, the refrigerant is the fluid that absorbs and transfers heat from one part of the air conditioning system to another. There are two coils in your AC unit, and this is where the refrigerant lives. While in the evaporator coil, the refrigerant changes from a liquid to a gas as it absorbs the heat from the air blown over the coil. The refrigerant is pumped to the condenser coil where it releases the heat it just absorbed, and subsequently turns back into a liquid. The cycle continues, and your home stays nice and cool.


While there is some routine maintenance you can perform on your air conditioning unit yourself, dealing with the refrigerant is not one of them! The most common refrigerant used in AC units is called Freon, and it should only be handled by professionals.


It’s imperative that you get your air conditioner’s refrigerant levels checked often. A 10% loss of refrigerant will cost the owner 20% more in electrical costs and can cause excessive wear and tear on your unit.

Low levels of refrigerant can also cause compressor failure, reduce efficiency, freeze the evaporator coil, among other problems.

How Often?

The Air Conditioning Contractors of America (ACCA) recommends getting the refrigerant levels checked once a year.

If your air conditioner is not producing as much cold air, as usual, make sure to call in a technician to take a look at your refrigerant levels!
