Why is my AC system freezing up?

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

Double-checking the air filter isn’t dirty and airflow isn’t lowered are the only things you can safely handle on your own. If you need to install a new the filter, you can speed up the thawing process by switching off the equipment and turning on the fan. If you have a heat pump, you can switch it to heat mode until the ice has melted.

After the ice melts, 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 unit may be freezing up.

Low refrigerant—A frozen system may be created by a refrigerant leak.

What leads to a leak?

  • Weak solder joints
  • Resistance from piping jarring against an object
  • Ruptured valves
  • Unsecured fittings

How long your system has been running and the area 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 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 can also be intermittent, running at top 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 trouble.

Booking annual AC maintenance or heat pump maintenance may help you skip this malfunction. Our technicians will meticulously check and clean your unit, which frequently allows us to notice small issues before they turn into large issues.
