Ice on the Coils? Here’s What You Can Do


Before you take out a hairdryer and start melting the ice off your air conditioner’s coils, we advise you to read this blog and contact a professional! Delaying on professional AC repair in Garland, TX will only make things worse, and ice growing on the coils of your air conditioning system is a serious problem.

Today, we’d like to talk about this issue and how cooling can go wrong. Especially as we start getting into the latter half of springtime, temperatures are only going to continue increasing and our dependency on air conditioners will get more intense. If your AC is encountering a problem like this, we’ll examine it in this blog post and give you the details on what exactly is happening.

Just make sure you get things done right the first time by calling the team at Aire Texas Heating and Air Conditioning!

Why Ice Forms on the Coil

Your air conditioner does not use ice to cool your home. Think about it this way: ice is actually an incredibly inefficient method of cooling a home, and it takes way more energy to keep ice cool than it does to cool a space like your house. Ice is also wet, and moisture doesn’t mix well with our technology or air quality, so ice just isn’t an HVAC technician’s friend.

That being said, it can appear on an air conditioner’s coil for a very specific set of reasons. Here are just a few reasons why ice might be forming on your AC’s outdoor cabinet:

  • The air filter is clogged. A clogged air filter will contribute heavily to stagnant air because it’s stopping the airflow of your system. If air gets cooled but can’t go anywhere, it’s going to continue to cool until it freezes everything around it. Replace your air filter and see if the problem persists.
  • The system is suffering from a refrigerant leak. When an air conditioning unit has less refrigerant, it’s going to run in faster, shorter cycles. Since it’s not running at normal capacity, the refrigerant could get too cold and lead to an ice build-up.
  • The fan system is broken. If there’s no fan that’s pushing the cool air out of the system and into your home, then it’s going to lead to frigid temperatures in one small space.
  • The coils are dirty. Dirty coils can’t absorb heat the same way that clean ones can. This means your dirty coils could be contributing to ice growth as well.

“Ice Is Cold, So What’s the Big Deal?”

Ice is a big problem. It doesn’t matter if it’s cold; that coolness isn’t getting sent throughout your home! Ice usually forms in places where you can’t feel it, and that’s not good.

Also, ice will eventually melt and cause a ton of moisture problems that you’ll have to deal with later on, so it’s important to get this problem addressed ASAP.

The Worst-Case Scenario

Our Plano heating and cooling technicians at Aire Texas can help you figure out what’s going wrong. The worst-case scenario is that your system is shutting down and needs to be replaced. However, we might also be able to fix the unit, recharge leaking refrigerant, and otherwise provide a boon that keeps it running for another season.
