Help! My Air Conditioner Keeps Freezing

Posted on: May 16, 2016

Air conditioner issues, while unpleasant, aren’t exactly all that uncommon. Most homeowners in Plano experience a need for professional repair at least once or twice. But not all problems are created equally and some of them can be downright baffling! Has your air conditioner decided it wants to make the transition from temperature control to ice cube maker? Our experts can help!

At Total Air & Heat, our seasoned specialists have been providing quality cooling solutions for years and we know more than a thing or two about air conditioner repair! We’ve handled countless air conditioners that have begun to freeze up and we would like to shed a little light on the issue.

Why Do Air Conditioners Freeze or Ice Over in Dallas?

We could, at this point, go into a fairly extensive science lesson. We’ll spare you the jargon, but if you’re curious, look into The Joule-Thomson Effect of thermodynamics. Despite this being a fairly unique issue, there are actually quite a few potential causes (though some are much more common than others):

  • Improper usage. We’re not pointing any fingers here, as it’s actually a pretty common reason for a freeze up. If you attempt to operate your air conditioner if it’s say, sixty degrees outside, you are more than likely going to end up with a frozen unit. This is because the higher pressure outside will create an imbalance with the higher pressure inside. Air conditioners were built to operate with specific temperature ranges in mind, and outside of those, you can end up with a variety of issues.
  • Poor internal air flow. Your system is designed to, despite what you may think, remove heat from your home rather than just blow cold air in. This system is dependent on three major components: the compressor, the evaporator, and the condenser. When refrigerant makes its way through the evaporator coils (the last step in the process), air is blown across the coils to transfer cool air into the home. If the airflow is constricted, or fails to operate, it throws the whole process into the trash and can result in a system freeze.
  • Low refrigerant levels. Common sense would say too much refrigerant would cause a freeze up, right? Well, common sense isn’t all that tech-savvy. If the refrigerant in your system is low, it has no impact on the processes of your system. This means that the amount of refrigerant that is still in your system is required to expand more to fill the empty space. This occurrence will drop the temperature of your air conditioner’s components, resulting in a freeze.

Surprisingly diverse set of causes, right? Air conditioner freezes aren’t the most common issue in the world and if you encounter one it can be hard to find the cause all on your own. Mostly because to check for poor air flow, or a refrigerant leak, you need the tools and knowledge of a professional HVAC specialist. But that’s what the experts at Total Air & Heat are here for!
