What Causes an Air Conditioner to Freeze Up?
If your air conditioner is freezing up, there are a few simple troubleshooting questions you can try out before considering total replacement.
Is My AC Getting Enough Ventilation?
Air conditioners need to have reliable intake and exhaust in order to function. This means if you have objects blocking many vents, that could be the source of your problems. Filters that are clogged can have a similar effect. This is partly why HVAC pros recommend you change out filters multiple times a year, with exact frequency depending on how many people and animals reside with you.
Is My AC Set Too Low?
The lowest temperature most residential units are designed to maintain is 67° F. So setting the temperature any lower than that may contribute to the freezing-over. Some people mistakenly assume setting the AC lower will result in it reaching an acceptable temperature faster. But this does little good and can do much harm if you forget about it.
Is My AC Leaking Coolant?
Unlike the first two questions, this one lacks an easy fix. If you suspect there is a leak, then you should get in touch with an HVAC professional. You’re going to need someone with a license to legally replace any Freon or other coolant.
