What Causes My Air Conditioner to Freeze Up?
Considering that air conditioners run during hot summer days that can exceed one hundred degrees in Las Vegas, Nevada, you would expect that the last thing they would do is freeze. However, that is precisely what extreme heat and strain on an air conditioning unit will cause.
Since air conditioners pass air through an AC coil in order to cool it, they also absorb a lot of debris. A properly running unit will have a cool coil which passes air into the home. Whereas a unit which has had its coils clogged with debris will freeze up completely and air will not be able to pass through it.
Freezing can also occur because of clogged air filters, damaged ducts which don’t allow a proper amount of air to flow out of the AC unit, and refrigerant issues. Without enough refrigerant an AC unit will have lower pressure, extra moisture, and a higher potential for freezing. Another possibility, although this doesn’t happen as often, is an overfill of refrigerant which causes the unit to not effectively move heat.
While freezing can occur sometimes merely because an ineffective unit is being overworked, it is mostly caused by another impending problem on the system as listed above, or by a mechanical problem. Clogged lines in air conditioning units for example are a mechanical problem which may result in freezing, as would be a kink in a liquid line, a malfunctioning valve, or a blockage somewhere in the unit.
If the fan which takes cold air passed through the coil and circulates it into the home’s ducts is not working, it will cause the cold air to cool the unit extremely to the point where it freezes as well. By the time this happens due to a system malfunction, a lot of damage can occur to a unit. That is why it is recommended to maintain units annually which covers an intensive check of all components, as well as a tune-up.

Symptoms of a Frozen Unit
If your home is no longer being cooled but your unit is on, or if it shuts down, it may be caused by freezing. Sometimes ice will be visible within the unit but it isn’t always something that one can see without first opening it.
When ice is not visible within the unit, you may be able to hear it occasionally. It will sound like ice falling down and hitting metal, as that is what happens in some units when they freeze and continue to run. Before a unit completely malfunctions due to freezing you may be able to catch it early on if you notice a significant change in the temperature of your home.
If anything seems off with your air conditioner it is always best to turn it off and call our technicians at 702-489-5500. This will insure that an AC unit with an issue doesn’t keep running for hours and days before it completely freezes over or breaks down.
Preventing Frozen AC Units in Las Vegas
In addition to annual maintenance, there are other steps you can take to prevent your unit from freezing over. This includes keeping mulch, dirt, and other debris away from the unit so that it does not clog it. As well as spraying it with water once a month to make sure that it always remains clear. When cleaning an AC unit with water it is important to not spray water inside, but rather just on the sides. And do not use pressure. Simply run water over the sides.
Keeping filters clean, as well as changing them regularly every few months is another great way to prevent your unit from freezing. This insures that the pressure within the unit is stable and not thrown off by a clogged filter.
During the day you can also set your thermostat to cool the house less, if no one is home. In addition to putting less strain on the unit and extending its life-span, it will also lower monthly energy bills.
