Why does my AC Freeze up?

At first, it can seem quite puzzling as to why something that is meant to work during the hottest time of the year would literally freeze. Despite the irony, there are actually three good reasons as to why an AC has frozen up: 

1) Blocked Airflow

If your AC unit doesn’t have a consistent flow of air, then the humidity inside will settle on the coils and slowly freeze into a block of ice. This is prevented by making sure that your air filters are not clogged or being blocked from the outside. Thankfully, air filters are inexpensive and easy to replace with the help of a professional appliance repair team.

2) Refrigerant Leaks

Another reason why an AC is freezing up could be because the refrigerant has started to leak. This could be because one of the lines might have been kinked or perhaps even somehow clogged from a storm. When this happens, the lines start to expand and leak fluid. It’s only a matter of time until the AC unit freezes up and fails, leaving you in a sweltering-hot home in the summertime! If your AC unit has been impacted by weather or abuse, it’s a good idea to have it inspected by a professional appliance repair service. You might require a new unit entirely if the damage is extensive; most fixes for coolant leaks are often temporary at best. 

3) Mechanical Problems

There are many different moving parts inside of an air conditioner that could cause it to freeze up if any of them fail. Inside of your AC unit are fans, bearings, pumps, and more than all work synergistically to keep you cool. If you start hearing metal-on-metal noises coming from your AC, then it’s probably time to call a professional AC repair service so that you can have a trained expert look at it before any catastrophic failure happens! 

A freezing AC is actually quite common, and it presents a frustrating situation that many homeowners encounter in their lives. However, so long as you use a professional appliance company such as Magnolia Heating and Cooling to service your air conditioner, then you can prevent clogs, leakages, and mechanical failures. Hiring a heating and cooling service to regularly maintain and inspect your AC unit will keep it in tip-top condition so that you (and your checking account) can rest in cool, quiet comfort.
