Prevent Freezing your AC Unit

With the temperatures rising because of spring, you want to be sure your air conditioning unit does not freeze up. The worst thing that can happen in an 80-90-degree day is for your air conditioning unit to not work because the coils have frozen up. Luckily, there are some measures you can take to prevent this from happening so you can enjoy the comfort of your home no matter what Mother Nature throws your way. Follow these steps to ensure your air conditioning unit doesn’t freeze up this spring.

Regularly Change Your Air Filters

Having routine maintenance on your air filters is just one thing you can do to prevent your air conditioning unit from freezing up. In order to prevent your unit from freezing, make sure you are replacing your air filter monthly. If you neglect changing your air filters, then the cold air will get clogged up and be forced back into the air conditioning unit, causing it to freeze. The air coming out of the unit is so cold, that it can literally freeze over the unit if you aren’t regularly replacing your air filters.

Refrigerant Levels

Low refrigerant level in your air conditioning unit is another common problem that can lead to a frozen air conditioning unit. If you suspect this is the case, then it is important to call an HVAC specialist to either top off your refrigerant level or repair a possible leak. When your air conditioning unit is running low on refrigerant, the temperature of the coils in your unit will begin to drop and ultimately begin to freeze. You can prevent this from happening by constantly checking and monitoring leaks in your unit and call a professional the moment you have identified the leak.

Outdoor Temperature Below 60 Degrees

Another common cause of a frozen air conditioning unit is not running it at proper times. For example, air conditioning units freeze more when the outside temperature is 60 degrees or below. This is because most air conditioning units are not designed to blast your home with cold temperatures when the temperature outside is already cold. The cold temperature outside paired with the cold temperature of the air conditioner cooling your home make a frozen air conditioning unit much more likely. To prevent this, make sure you are only running your air conditioning unit when the temperature outside it warm enough that it is heating up your home.
