Why is my AC system freezing up?

There are many reasons why your AC system freezes up.

Checking the air filter isn’t dirty and airflow isn’t lowered are the only work you can safely handle without professional help. If you need to put in a new the filter, you can hasten the melting process by switching off the system and switching on the fan. If you have a heat pump, you can turn it to heat mode until the ice is gone.

After the ice melts, turn the temperature back to normal. If your equipment freezes again, get in touch with Service Experts Heating & Air Conditioning to take care of the issue.

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

Not enough refrigerant—Freezing up could be created by a refrigerant leak.

What leads to a leak?

  • Weak solder joints
  • Friction from piping vibrating against an object
  • Cracked valves
  • Loose fittings

How long your unit has been running and the location of the leak play a part in whether you should repair or replace your AC system.

Filthy evaporator coil—As time passes, the evaporator coil becomes dirty and leads to troubles resembling a dirty filter. You’ll gradually lose airflow until your unit freezes or stops 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 inaccurate speed or not turning on at all can cause freezing. It could also be intermittent, starting at top speed and decelerating after it gets warm. Or a relay may make it run one time and not the next. In either situation, you will need to get in touch with Service Experts Heating & Air Conditioning to fix the issue.

Requesting regular AC maintenance can help you skip this malfunction. Our Experts will thoroughly check and clean your unit, which frequently allows us to locate little troubles before they cause large troubles.
