What’s Making Your Air Conditioning Unit Freeze?

What's Making Your Air Conditioning Unit Freeze?

While we won’t go into depth about thermodynamics here (and we wouldn’t expect you to stick around if we did) this is what your common air conditioning problems boil down to. A part of your air conditioner freezing up can be a result of many things messing with this process. You’ll most likely need a professional to tell you what’s going wrong with your unit, and that’s where Hatton’s HVAC Solutions will come in. In the meantime though, take a look at the common things that can go wrong with an AC unit, causing it to freeze. 

Improper Air Flow Can Be to Blame

There needs to be air flow over an air conditioner freon coil in order for the right exchange of temperatures to take place. If this doesn’t happen or stops happening, it’s easy for an AC freeze to occur. Improper air flow can occur from a blocked vent, clogged air filter, an outdated unit, and more.  

It Needs More Refrigerant 

If your air conditioning unit runs low on this important fluid, the pressure will decrease in your unit. As the evaporator coil in your unit drops to a temperature that’s lower than normal, moisture freezes as it hits the coil, leading to a buildup of ice. 

The Temperatures Aren’t Matching Up

Air conditioning units are programmed to work efficiently between certain temperatures. If it’s cold outside and you’re still cooling off the inside of your home (we’re not sure why you’d want to do this, but it can still happen) parts of your air conditioning unit may freeze up. 

There’s a Problem with Mechanics

As mentioned above, a number of technical problems can lead to a freeze. Instead of wasting time with speculation, be sure to contact a professional, especially if you think ice build up will permanently damage your unit.   

How to Thaw Out the Problem

While you could take the time hovering around your AC unit and blasting a frozen coil with hot air from a hairdryer, it’s easier and more effective to stop running the unit. Continuing to run it while the coils are frozen can strain its parts and cause the unit to completely break down. Let the ice melt that’s accumulated on the coils and later dry the parts and puddling water.
