Why is my AC system freezing up?

There are lots of reasons why your AC system freezes up.

Checking the air filter isn’t clogged and airflow isn’t decreased are the only work you can safely handle alone. If you need to put in a new the filter, you can accelerate the defrosting process by switching off the unit and using the fan. If you have a heat pump, you can move it to heat mode until the ice is gone.

After the ice melts, move the temp back to normal. If your system freezes a second time, get in touch with Service Experts Heating & Air Conditioning to repair the problem.

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

Not enough refrigerant—Freezing may be caused by a refrigerant leak.

What causes a leak?

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

How long your unit has been running and the spot of the leak determine whether you should repair or replace your AC system.

Filthy evaporator coil—Over time, the evaporator coil attracts dirt and creates troubles resembling a clogged filter. You’ll progressively get lower airflow until your equipment freezes or halts cooling. You’ll need to get in touch with Service Experts Heating & Air Conditioning to take care of the malfunction.

Malfunctioning blower motor or relay—A blower motor working at an inaccurate speed or not working at all can create freezing. It might also be irregular, starting at maximum speed and decelerating after it heats up. Or a relay could make it start one time and not the following time. In either situation, you will need to call Service Experts Heating & Air Conditioning to correct the problem.

Requesting yearly AC maintenance can help you bypass this problem. Our professionals will thoroughly examine and clean your unit, which frequently allows us to locate little issues before they cause huge issues.
