Why is my AC system freezing up?

There are lots of reasons why your AC system freezes up in Fort Lauderdale. Almost all of them typically need pro AC repair.

Making sure the air filter isn’t dirty and airflow isn’t restricted are the only tasks you can safely take care of on your own. If you need to replace the filter, you can accelerate the melting process by switching off the unit and switching on the fan. If you have a heat pump, you can move it to heat mode until the ice is gone.

After the ice disappears, move the temperature back to normal. If your equipment freezes a second time, contact Service Experts Heating & Air Conditioning to repair the issue.

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

Insufficient refrigerant—Freezing up can be caused by a refrigerant leak.

What leads to a leak?

  • Fragile solder joints
  • Resistance from piping rubbing against other parts
  • Ruptured valves
  • Loose fittings

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

Dirty evaporator coil—Throughout the seasons, the evaporator coil gets dirty and creates troubles resembling a dirty filter. You’ll progressively receive lower airflow until your unit freezes or halts cooling. You’ll need to contact Service Experts Heating & Air Conditioning to take care of the malfunction.

Defective blower motor or relay—A blower motor going at the wrong speed or not turning on at all can result in freezing. It can also be sporadic, starting at maximum speed and decelerating after it heats up. Or a relay may force it to run one time and not the following time. In either state, you will need to contact Service Experts Heating & Air Conditioning to repair the issue.

Scheduling annual AC maintenance or heat pump maintenance may help you skip this malfunction. Our Experts will fully check and clean your unit, which often allows us to pinpoint small troubles before they turn into large problems.
