Air conditioner freeze-ups are a perplexing and inconvenient problem. ACs tend to freeze up during the peak heat of the summer months, and it can be bizarre to see your air conditioner frozen with the summer heat beating down on it. Can this be fixed? Yes – and it’s important to get it fixed as soon as possible, because as ice continues to build it up it could cause permanent damage to the system.
What Causes AC Freeze-Ups?
Freeze-ups can be caused by a number of different problems with your home’s air conditioning system:
Insufficient air flow:
Anything that restricts air flow can cause the temperature of your AC’s evaporator coil to drop below freezing. Humidity in the air can then collect of the coil, which will cause ice to build up and diminish the system’s cooling capacity. Some things can seriously impede air flow include dirty air filters, collapses or undersized ducts, dirty ducts, damaged blower motors, or build-up on the evaporator coil.
Problems with the System’s Refrigeration:
Refrigerant leaks or low levels of refrigerant can cause the pressure of your AC’s evaporator coil to drop, which will allow moisture in the air to freeze and accumulate on the coil.
What To Do when your Air Conditioner Freezes Up
If you notice your AC system does not seem to be working well, one of the first problems you consider should be ice build-up. Immediately turn your air conditioner off completely to let it defrost.
