Why is my AC system freezing up?

There are lots of reasons why your AC system freezes up in Waldorf. Most all of them typically require skilled AC repair.

Checking the air filter isn’t dirty and airflow isn’t decreased are the only tasks you can safely take care of on your own. If you need to install a new the filter, you can accelerate the defrosting process by switching off the equipment and using the fan. If you have a heat pump, you can move it to heat mode until the ice has melted.

After the ice disappears, switch the temp back to normal. If your equipment freezes a second time, contact A-PLUS Service Experts to repair the malfunction.

Here are several other reasons why your equipment could be freezing up.

Low refrigerant—A frozen system can be caused by a refrigerant leak.

What leads to a leak?

  • Fragile solder joints
  • Grating from piping rubbing against an object
  • Ruptured valves
  • Unsecured fittings

How long your system has been installed and the spot of the leak play a role in whether you should repair or replace your AC system.

Dusty evaporator coil—Throughout the seasons, the evaporator coil becomes dirty and causes troubles much like a clogged filter. You’ll slowly lose airflow until your equipment freezes or quits cooling. You’ll need to contact A-PLUS Service Experts to fix the malfunction.

Broken blower motor or relay—A blower motor going at an incorrect speed or not turning on at all can cause freezing. It might also be sporadic, running at top speed and slowing down after it gets too hot. Or a relay could force it to start one time and not the subsequent time. In either situation, you will need to contact A-PLUS Service Experts to correct the issue.

Scheduling regular AC maintenance or heat pump maintenance can help you skip this malfunction. Our techs will meticulously check and clean your equipment, which often allows us to locate small issues before they become major problems.
