The Trouble with a Frozen Evaporator Coil

For many parts of the country, the official start of fall in just a couple of weeks means that the weather will soon cool down and air conditioners will begin to be shut off for the season. As we are all well aware, this is not the case for Floridians!

In order to ensure that you’re ready for the remaining hot temperatures we have left, it’s important to keep an eye out for problems with your air conditioning system. This is particularly important this time of year, as your system has been hard at work all during summer, and the extra strain can cause a breakdown if the AC unit is not properly maintained and cared for.

One of the most common service calls we get about malfunctioning air conditioners is in regards to a frozen evaporator coil. You may think that this is a normal occurrence, but once you notice your cooling output dropping you’ll know otherwise.

What Causes Evaporator Coils to Freeze Over?

One reason your evaporator coil may freeze over is due to a clogged air filter. The air filter that came standard with your HVAC system is designed to protect the interior components of that system. If it’s too clogged, then your evaporator coil may accumulate dust and other debris, preventing it from absorbing the hot air from your home as it should.

Refrigerant leaks are another common cause for a frozen evaporator coil. What happens is that when your refrigerant is running low, your evaporator coil isn’t able to absorb heat as it should, so the leftover refrigerant in the coil gets too cold, leading to moisture on the coil freezing. A refrigerant leak is something that must be addressed right away, both for this reason and because it endangers other components of your air conditioner.
