What Does a Frozen Evaporator Coil Mean?

As we are all very well aware, there’s really no rest from the heat when you live in Florida, save for a couple months of somewhat cooler weather. This is why it’s so important to take care of our cooling systems, by scheduling maintenance and by staying on top of repair needs. The last thing you want during a blazing hot day is to be stuck with a malfunctioning AC unit.

A common service call we get in regards to air conditioners is that of ice developing on the indoor evaporator coil. Many clients ask us if this is normal, since after all, your AC system is supposed to send out air that feels like it was chilled by ice. But no, you should never see ice developing on any part of your air conditioner if it’s working properly. Keep reading to learn what this could mean.

A Clogged Filter

The air filter that comes standard with your HVAC system is there to protect the inside components from any airborne contaminants that can come through the return ducts. Your filter easily becomes clogged with dust and lint, in addition to pet dander and cigarette smoke should those contaminants be in your home.

A clogged filter doesn’t allow enough warm air to flow over the cold evaporator coil, thus resulting in the development of ice. Be sure to change your air filter every 1-3 months as needed to ensure this doesn’t happen.

Dirt along the Evaporator Coil

If your evaporator coil is subjected to enough dirt and dust, then it can become insulated, preventing it from absorbing heat as it’s supposed to. As a result, the refrigerant flowing through the coil will stay too cold, which triggers the freezing process.

Refrigerant Loss

If your AC system is leaking refrigerant, then your evaporator coil is unable to absorb as much heat as usual. So, the refrigerant that is still in your system remains too cold, leading to moisture freezing.

Whatever the cause of your system’s ice development is, it’s vital that you call for professional services. Attempting to remove the ice yourself can damage your system further, plus it’s not getting to the root of the problem—making it more likely to happen again.
