It’s the middle of another hot Florida summer, so why would your AC unit freeze up? It may be hard to believe, but your unit can freeze up even on the hottest days. If you notice ice building up on your unit, it’s not a good thing.
What Causes AC Units to Freeze Up?
Your AC unit can fall ill to a summer chill if it’s not being maintained as it should. There are three main reasons why your unit is freezing up.
First, your unit can start icing up if it can’t breathe. If your unit is suffocating, the coils in your unit can’t circulate air and in return, will get too cold. When the coils get too cold, it freezes the moisture from Florida’s humidity. Now you’ve got an icy AC unit that can’t keep you cool!
Airflow problems in your unit can be the result of a couple of different things including:
- Dirty air filters (seriously change your filter!)
- There aren’t enough return vents in your home
- You have damaged or dirty ductwork
Next, your unit may be experiencing refrigerant problems which will cause your unit to turn into an icebox. Wear and tear on your AC unit will cause refrigerant leaks. It’s only a matter of time before your AC falls victim to a summer cold when there’s a leak.
When your refrigerant is low, your coils get too cold and you guessed it, will freeze up. Adding more refrigerant isn’t the solution. It may be a quick fix, but the problem could occur again. In these cases, it’s best to just give us a call and we’d be happy to repair your unit!
The coils in your unit are essential for a smooth cooling process. They are responsible for cooling and dehumidifying the air that comes into your unit. When your coils are dirty, it hinders airflow and can’t manage the moisture within your unit. This causes moisture to overflow into the drip pan and freezes up.
Frozen AC Unit…What Now?
If your unit is frozen, you’ll need to turn off your air conditioning to allow it to thaw. In the meantime, check your AC filter to determine that’s not the cause of your frozen unit. Once completely thawed, turn your AC back on and check the temperature of the air coming out of your vents.
If it’s an internal problem, please call us for service! You don’t want to go without air conditioning or cause more damage to your unit.
How to Prevent Future AC Freeze Ups
You don’t want your unit to be left out in the cold! Preventing AC freeze ups will save time, money, and stress. You can be proactive about freeze ups by:
- Scheduling regular AC tune-ups. We clean your coils and check for leaks during tune-ups!
- Changing your air filter. Dirty filters are no fun and won’t let your unit do its job.
- Keeping your supply vents open. Even if you aren’t using that spare bedroom, keep all of your supply vents open to ensure that pressure isn’t being built up in your ductwork.
- Making sure your thermostat is working. Thermostat problems can inadvertently mess with your unit.
