Why is my AC system freezing up?

There are a lot of reasons why your AC system freezes up in Savannah. Almost all of them usually require professional AC repair.

Making sure the air filter isn’t clogged and airflow isn’t lowered are the only work you can safely fix without professional help. If you need to replace the filter, you can accelerate the melting process by turning off the equipment and using the fan. If you have a heat pump, you can switch it to heat mode until the ice has disappeared.

After the ice is gone, turn the temp back to normal. If your unit freezes repeatedly, contact Coastal Service Experts to fix the issue.

Here are a couple other other reasons why your unit may be freezing up.

Low refrigerant—A frozen system can be a result of a refrigerant leak.

What leads to a leak?

  • Fragile solder joints
  • Friction from piping vibrating against an object
  • Ruptured valves
  • Loose fittings

How long your system has been working and the spot of the leak determine whether you should repair or replace your AC system.

Dirty evaporator coil—As time passes, the evaporator coil gets dirty and causes issues much like a dusty filter. You’ll slowly get lower airflow until your unit freezes or quits cooling. You’ll need to get in touch with Coastal Service Experts to repair the issue.

Defective blower motor or relay—A blower motor working at an incorrect speed or not running at all can create freezing. It could also be irregular, going at maximum speed and going slower after it gets warm. Or a relay may make it run one time and not the following time. In either state, you will need to get in touch with Coastal Service Experts to correct the issue.

Requesting yearly AC maintenance or heat pump maintenance can help you skip this issue. Our technicians will meticulously check and clean your equipment, which typically allows us to find little troubles before they turn into large troubles.
