Why is my AC system freezing up?

There are a lot of reasons why your AC system freezes up in Livermore. Almost all of them usually need professional AC repair.

Double-checking the air filter is clean and airflow isn’t lowered are the only things you can safely handle alone. If you need to install a new the filter, you can accelerate the melting process by switching off the unit and turning 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, turn the temperature back to normal. If your system freezes repeatedly, call Service Experts Heating & Air Conditioning to fix the problem.

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

Insufficient refrigerant—Freezing may be caused by a refrigerant leak.

What creates a leak?

  • Weak solder joints
  • Resistance from piping vibrating against other parts
  • Broken valves
  • Unsecured fittings

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

Filthy evaporator coil—Over time, the evaporator coil attracts dirt and leads to issues resembling a clogged filter. You’ll slowly get lower airflow until your equipment freezes or halts cooling. You’ll need to get in touch with Service Experts Heating & Air Conditioning to repair the issue.

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 top speed and going slower after it heats up. Or a relay could make it start one time and not the following time. In either state, you will need to call Service Experts Heating & Air Conditioning to correct the problem.

Requesting yearly AC maintenance or heat pump maintenance may help you skip this problem. Our professionals will meticulously examine and clean your equipment, which frequently allows us to spot little issues before they turn into major issues.
