One of the most common issues with air conditioners that we run into is a unit that has completely frozen up on the homeowner. While air conditioners are supposed to keep you cool, the units themselves are never supposed to freeze up — literally. If you walk into your utility room and see that your AC is covered in a coat of frost, there is a problem going on. When your air conditioning unit freezes up, it is indicative of some problems going on in your system. Unfortunately, there isn’t just one trigger for a frozen air conditioning unit, there are actually a couple of different triggers that you need to be aware of.

Lack Of Air Flow

If your air conditioning unit is struggling to get enough air flow, there won’t be enough warm air in the system. When you don’t have enough warm air coming through your AC, the condensation on your coil will begin to freeze. We advise getting on a maintenance agreement in order to routinely change your air filters.

Dirty Evaporative Coil

When your evaporative coil gets dirty, the obstruction causes a buildup of condensation in the system. When this condensation begins to accumulate, it can freeze.

Low Refrigerant

Low refrigerant levels are a key trigger to a frozen air conditioner. When your AC unit is low on refrigerant, the freon will behave differently. Your refrigerant will be forced to expand, even more, causing your evaporator coil to drop its temperature, thus inducing freezing temperatures.
