Unfortunately, as great as air conditioners are they are not flawless and every once in a while, they can break down too. What to do in such cases?

There is not just one thing that can go wrong with air conditioners, in fact, there are many but the most common one is freezing. So, for this article, we will focus on air conditioner freezing and I will share some tips that will help you to keep away your favorite appliance from freezing up.

Frozen air conditioning

How do you know if it’s frozen?

It’s actually simpler than you think. In most cases your air conditioner will have ice hanging on it, so there you have it, a visible evidence that your AC is frozen. In other cases, just try to feel the air with your hands and if you can’t then there is a good chance that something is blocked inside and that’s a sign of a frozen air conditioner.

Why does the AC freeze in the first place?

Excellent question! Well, there are multiple causes of freezing including low refrigerant levels, which is an installation mistake, so you will have to have a professional over to fix it. Another reason is closed supply registers. Perhaps a friend suggested you close some of the supply registers around the house to save on energy but keep in mind that it can lead to a frozen AC. Dirty air filters could very likely cause an air conditioner to freeze as well.

There are other sources too, but these are the basics so, you should keep an eye on them if you are trying to prevent the freezing.

So, what should you do?

It’s actually based on our previous section of causes. Here are a couple of tips that have proven to be useful and really effective when it comes to air conditioning:

  • Constantly check the refrigerant level
  • Have scheduled filter changes
  • Increase the fan speed
  • Don’t block the supply vents

You can put it on your calendar or set a reminder or even assign it as a chore to your kid but taking care of your air conditioning and watching out for these tips is absolutely necessary if you are trying to avoid frozen air conditioners.

What to do if it froze after all?

Sometimes our efforts are not enough to manage to keep air conditioner from freezing. There are still some things that you can do for damage control until a professional technician can take a look and make the repairs. As soon as you notice that your air conditioning is iced up shut it off. If you don’t the AC will keep burning electricity but with no results. You don’t want to pay money for wasted electricity, right?

Next you are going to wait until the ice melts so that you can find the condensate drain to see whether it’s blocked or no. If it is not, then empty it. Just a side note, you can also use a blow dryer to melt the ice and unblock the AC.  Try turning the air conditioner back on. It should start working again if no then call an AC repair service as the problem may lie somewhere else and you don’t want to make it worse.

Be safe

As much as you want to fix the AC on your own, keep in mind that you are working with an appliance that works with electricity so, there are always risks involved. Make sure you comply with safety measures before attempting to repair your AC.
