Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Orlando. Nearly all of them frequently require skilled AC repair.

Double-checking the air filter isn’t dusty and airflow isn’t restricted are the only work you can safely fix without professional help. If you need to install a new the filter, you can accelerate the thawing process by disabling the system and using the fan. If you have a heat pump, you can turn it to heat mode until the ice has melted.

After the ice is gone, move the temp back to normal. If your system freezes a second time, contact Service Experts Heating & Air Conditioning to correct the malfunction.

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

Low refrigerant—Freezing can be created by a refrigerant leak.

What leads to a leak?

  • Fragile solder joints
  • Resistance from piping rubbing against other parts
  • Broken valves
  • Slack fittings

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

Dirty evaporator coil—Over time, the evaporator coil attracts dirt and creates troubles much like a dusty filter. You’ll slowly get lower airflow until your system freezes or halts cooling. You’ll need to contact Service Experts Heating & Air Conditioning to repair the malfunction.

Defective blower motor or relay—A blower motor working at an incorrect speed or not running at all can create freezing. It might also be intermittent, going at maximum speed and decelerating after it gets too hot. Or a relay could cause it to work one time and not the next. In either case, you will need to contact Service Experts Heating & Air Conditioning to fix the problem.

Booking yearly AC maintenance or heat pump maintenance could help you bypass this problem. Our techs will meticulously examine and clean your unit, which often allows us to spot minor problems before they become major issues.
