Why is my AC system freezing up?

There are a lot of reasons why your AC system freezes up in Wheeling. Most all of them typically call for professional AC repair.

Making sure the air filter isn’t dirty and airflow isn’t lowered are the only work you can safely fix without professional help. If you need to install a new the filter, you can accelerate the melting process by switching off the system and turning on the fan. If you have a heat pump, you can turn it to heat mode until the ice is gone.

After the ice melts, move the temp back to normal. If your system freezes repeatedly, contact Comfort Masters Service Experts to take care of the problem.

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

Insufficient refrigerant—A frozen system could be a result of a refrigerant leak.

What causes a leak?

  • Fragile solder joints
  • Grating from piping vibrating against other components
  • Cracked valves
  • Unsecured fittings

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

Dirty evaporator coil—Over time, the evaporator coil gets dirty and leads to troubles similar to a dusty filter. You’ll slowly lose airflow until your system freezes or quits cooling. You’ll need to get in touch with Comfort Masters Service Experts to fix the problem.

Malfunctioning blower motor or relay—A blower motor running at the wrong speed or not running at all can lead to freezing. It may also be intermittent, starting at top speed and going slower after it gets warm. Or a relay can force it to run one time and not the subsequent time. In either situation, you will need to call Comfort Masters Service Experts to fix the problem.

Requesting regular AC maintenance or heat pump maintenance could help you bypass this problem. Our pros will fully examine and clean your unit, which frequently allows us to catch little problems before they become large problems.
