Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Hurricane. Almost all of them usually require skilled AC repair.

Checking the air filter is clean and airflow isn’t decreased are the only work you can safely fix alone. If you need to put in a new the filter, you can accelerate the thawing process by disabling the unit and switching on the fan. If you have a heat pump, you can turn it to heat mode until the ice has disappeared.

After the ice disappears, turn settings back to normal. If your equipment freezes a second time, contact Teays Valley Service Experts to repair the malfunction.

Here are a couple other other reasons why your system could be freezing up.

Not enough refrigerant—Freezing may be a result of a refrigerant leak.

What creates a leak?

  • Weakened solder joints
  • Friction from piping rubbing against something
  • Ruptured valves
  • Loose fittings

How long your system has been running and the location of the leak play a part in whether you should repair or replace your AC system.

Dusty evaporator coil—As time passes, the evaporator coil becomes dirty and creates issues similar to a dirty filter. You’ll progressively lose airflow until your system freezes or halts cooling. You’ll need to contact Teays Valley Service Experts to take care of the malfunction.

Malfunctioning blower motor or relay—A blower motor working at an incorrect speed or not working at all can lead to freezing. It might also be irregular, going at top speed and decelerating after it gets too hot. Or a relay might make it work one time and not the following time. In either case, you will need to contact Teays Valley Service Experts to repair the problem.

Requesting annual AC maintenance or heat pump maintenance could help you avoid this problem. Our technicians will meticulously inspect and clean your equipment, which often allows us to notice small problems before they turn into major issues.
