Why Is There Frost in My Air Conditioner?

It doesn’t sound like a big deal: frost forming on the evaporator coils of your air conditioner. AC units are supposed to create cold air, so why should frost be a big deal? Unfortunately, the frost is usually a symptom of a larger problem, and as long as that problem remains unaddressed, your air conditioner will struggle more than it should to cool your home. Dover, DE residents need their air conditioners to combat our hot and muggy summers. That frost and ice may be a harbinger of a more serious problem, so the sooner you can have it addressed the better.

Problems

Frost can form for a number of different reasons, mostly related to maintenance. Dirt can build up on the coils, forming an insulating barrier between the refrigerant and the air it’s supposed to cool. Frost can also form if the refrigerant leaks out of the system, and sometimes the frost indicates a serious problem with a major component such as the compressor array.

Corrections

If you spot frost on your air conditioner, the last thing you want to do is scrape it off. In the first place, you’re not treating the core of the problem. The dirt would still be there, for example, or the refrigerant would still be leaking, and the frost would just form again. Furthermore, you may damage the coils in your efforts to scrape the frost off. A trained technician can solve the problem at the source, and if you wish to set up a regular maintenance session, you can prevent the circumstances that created the frost from forming again.

For repair problems associated with frost on your AC unit, or to set up a maintenance schedule to stop the problem before it starts, then the experts at Atlantic Refrigeration and Air Conditioning are standing by to help!
