Despite the hot summer weather outside, your air conditioning unit could be at risk of facing an unexpected problem – becoming frozen! This may sound impossible, but a fault in the unit can lead to this occurring. Read on to find out how to identify this problem and what to do when it occurs.

How to tell if you have a frozen AC

Contrary to what you might expect, your AC will be pumping out warmer air than it should do if it has become frozen. If you notice that your home is warmer than usual and it isn’t reaching the temperature you’ve set your AC to, then head over to the unit to check the temperature of the air coming out of it. Simply holding your hand in front of the air supply should let you feel if the air is too warm.

If you feel warm air, then your AC may be frozen. To check this, turn off your AC and open up the access panel to see inside of it – this can typically be done with just a screwdriver. You need to look at the evaporator coils. If they are covered in ice, then you’ve found your problem. If you’re unsure of how to open your AC unit or locate the coils, then you can always call out an AC repair technician.

How to fix it?

If your air conditioning is frozen, then you may be able to solve the problem simply by letting it thaw out. All you have to do is leave the unit switched off for 24 hours to let it defrost. Make sure you clear up any water before switching it back on. Don’t try to remove chunks of ice from the coils, as this can cause further damage.

Various things can cause your AC to become frozen, and the cause will determine the solution. To prevent your AC from freezing again, make sure that it is kept clean and clear of debris, especially the air filters, inside the vents, in front of the supply registers, and around the exterior unit. You should also make sure the coolant is topped up enough.

In some cases, these quick fixes may be enough. However, if there is a specific fault causing the AC to become frozen, then it may continue to happen. In this case, you will need to call out the professionals to diagnose and fix the problem.
