Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Mobile. Most all of them typically need experienced AC repair.

Making sure the air filter isn’t dirty and airflow isn’t decreased are the only things you can safely fix yourself. If you need to install a new the filter, you can accelerate the melting process by disabling the system and using the fan. If you have a heat pump, you can switch it to heat mode until the ice has melted.

After the ice melts, turn the temp back to normal. If your unit freezes a second time, contact Climate Control Service Experts to fix the malfunction.

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

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

What creates a leak?

  • Weakened solder joints
  • Grating from piping rubbing against other parts
  • Cracked valves
  • Loose fittings

How long your equipment has been running 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 gets dirty and leads to issues much like a dirty filter. You’ll progressively lose airflow until your equipment freezes or quits cooling. You’ll need to get in touch with Climate Control Service Experts to repair the issue.

Malfunctioning blower motor or relay—A blower motor working at an inaccurate speed or not running at all can create freezing. It may also be intermittent, running at top speed and going slower after it gets warm. Or a relay can make it work one time and not the next. In either situation, you will need to get in touch with Climate Control Service Experts to repair the issue.

Requesting annual AC maintenance or heat pump maintenance might help you avoid this malfunction. Our technicians will comprehensively check and clean your unit, which often allows us to notice minor troubles before they become huge troubles.
