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.

AC Repair or Replacement?

No matter the weather, there is something very obnoxious in having an air conditioner that isn’t functioning like it used to. The question is AC repair or replacement? But before getting to the big question, try answering these small ones for yourself.

Do you remember the age of your AC?

The experts say that the life of a single air conditioning unit is somewhere from 10 to 15 years. If you can’t even remember when you bought it or you even don’t know who bought it, because it came with the house, you have to know that an AC repair won't be enough. A new one will be much more efficient and can save you a huge amount of the electricity bill.

How often do you need AC repair?

If you have spent some time and money in repairing the old one but it still need some work, drop it off. A new one will have a warranty and will operate way more efficiently. And it’s new!

Using only one AC and still have high power bills?

If the bills are getting high, you should think of a new air conditioner. The recent AC models are more energy efficient and an initial investment could pay off in the long-run with lower energy bills.

How much was the cost of the last repair you’ve done?

Multiply the age of your current AC unit by the cost of AC repair. If the number exceeds 5,000 it might be a better option to replace than to repair. You also have to consider the cost of maintaining an old unit vs a new one, as well as the worth of your own time dealing with issues an old unit might give you.

There are so many benefits of replacing your AC unit, but if:

  • The AC repair cost is low
  • The unit is under 10 years old
  • You’re selling your house in the near future,
  • Your energy bills are reasonable
ongoing maintenance and tune-ups will be your best bet to getting the most time out of your AC unit and keeping costs down. If you have decided to replace your AC, read this article: How to Choose an AC?

Prepare for the Winter in 3 Steps


The summer is over and the heating season is soon to come. It’s time to prepare for the cold months. Here are our tips on how to get ready for the winter before it begins.

  1. Take care of your AC.

    The best thing you can do to assure your air conditioner will be working properly during the whole winter and not waste you more energy than needed is to call a professional to check your AC. They will open it, clean it and check if anything needs to be changed. However, if you are not willing to pay a professional to do this at the moment or you have done it soon enough, you can at least change or clean the filters of your AC. Here you can find detailed instructions on how to clean your AC filter on your own.

  2. Improve isolation

    If you still haven’t done it, we highly recommend you to isolate the outer walls of your home. This way you will keep your place warm in the winter and cool during the summer without loosing too much energy. Check the isolation of your windows for the same reason. To reduce the heat losses as much as possible, you can also put some thicker curtains on your windows. Make sure you place the curtain at least 5 cm over the window for better isolation.

  3. From Cooling to Heating

    Probably the easiest thing is to change your AC mode from cooling to heating. However, sometimes it’s not that easy to make the transition from one season to another. In the rainy autumn you may need to use fan function only to regulate the humidity. As people say, sometimes “it’s not the temperature, it’s the humidity”. Find some tips about humidity control here. Raise the temperature gradually. Give your air conditioner some time to reach your desired temperature, don’t rush it by choosing temperature much higher than what you need.
