Frozen AC - What to do?

During the coldest days of winter, the last thing you want is to come into a cold room just to find a frozen AC that won’t heat up the place fast. Unfortunately, this is a common problem in the winter, especially if you leave your AC off for a certain period of time. Luckily, your AC has its own way of dealing with such situations. However, sometimes it may need a little help from you.

Automatic Defrost Function in case of frozen AC

Have you ever turned your AC on, hoping it will heat up the cold room fast, but instead you feel like there’s cold air coming out of it for the first 20 minutes or so? This is probably because of the automatic defrost function of your AC. Here’s how it works: When you turn the AC on and set it on Heating mode, the unit detects that the outer body is frozen and it turns on defrost function. That means, it changes the working cycle and starts taking air from inside the room to the outer body to melt the ice on it. It basically switches from heating to cooling, lowering the fan speed, so that you don’t feel it like cooling. When the AC is ready defrosting its outer body, it starts heating.

What to do if AC Defrost function doesn’t help?

If you have any doubts your AC may be frozen, go check the outer body. If you find it covered with too much ice or snow, try cleaning it as much as you can. Make sure you don’t harm any parts of the outer body, in case you use sharp objects to remove the ice. Then let the AC melt the rest of it by itself. If have an evenly frozen AC, there won’t be a problem for it to defrost itself. However, if only one part of the outer body is frozen, there may be another problem that’s causing it. Call a technician to make sure your AC is working fine.
