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 decreased are the only work you can safely fix yourself. If you need to install a new the filter, you can speed up the defrosting process by switching off the system and using the fan. If you have a heat pump, you can move it to heat mode until the ice has disappeared.

After the ice disappears, turn settings back to normal. If your unit freezes again, get in touch with Rolf Griffin Service Experts to fix the issue.

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

Low refrigerant—Freezing could be a result of a refrigerant leak.

What creates a leak?

  • Weak solder joints
  • Resistance from piping jarring against other components
  • Broken valves
  • Loose fittings

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

Dusty evaporator coil—As time passes, the evaporator coil attracts dirt and leads to issues resembling a clogged filter. You’ll slowly get lower airflow until your unit freezes or stops cooling. You’ll need to call Rolf Griffin Service Experts to repair the issue.

Broken blower motor or relay—A blower motor working at an incorrect speed or not running at all can lead to freezing. It could also be intermittent, starting at full speed and going slower after it gets warm. Or a relay can force it to start one time and not the subsequent time. In either state, you will need to call Rolf Griffin Service Experts to correct the trouble.

Scheduling regular AC maintenance can help you skip this issue. Our Experts will meticulously inspect and clean your unit, which usually allows us to pinpoint small issues before they turn into huge problems.
