Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Fort Myers. Most all of them frequently call for professional AC repair.

Double-checking the air filter isn’t dirty and airflow isn’t decreased are the only work you can safely handle on your own. If you need to put in a new the filter, you can speed up the thawing process by switching off the unit 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 disappears, switch settings back to normal. If your system freezes a second time, contact Service Experts Heating & Air Conditioning to fix the problem.

Here are a few other reasons why your equipment may be freezing up.

Low refrigerant—Freezing up may be created by a refrigerant leak.

What leads to a leak?

  • Weak solder joints
  • Grating from piping jarring against an object
  • Cracked valves
  • Unsecured fittings

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

Filthy evaporator coil—As time passes, the evaporator coil becomes dirty and causes issues resembling a dusty filter. You’ll gradually receive lower airflow until your unit freezes or stops cooling. You’ll need to contact Service Experts Heating & Air Conditioning to repair the problem.

Defective blower motor or relay—A blower motor going at an incorrect speed or not turning on at all can create freezing. It might also be irregular, running at maximum speed and slowing down after it gets too hot. Or a relay might cause it to start one time and not the subsequent time. In either case, you will need to call Service Experts Heating & Air Conditioning to repair the issue.

Booking annual AC maintenance or heat pump maintenance can help you bypass this issue. Our pros will thoroughly check and clean your equipment, which frequently allows us to catch small issues before they turn into large issues.
