Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Denver. Nearly all of them typically need experienced AC repair.

Checking the air filter isn’t dirty and airflow isn’t decreased are the only work you can safely take care of alone. If you need to install a new the filter, you can speed up the thawing process by turning off the unit 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, switch the temp back to normal. If your equipment freezes again, get in touch with Service Experts Heating & Air Conditioning to fix the malfunction.

Here are several other reasons why your system might be freezing up.

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

What creates a leak?

  • Weakened solder joints
  • Grating from piping vibrating against other parts
  • Broken valves
  • Loose fittings

How long your equipment 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 causes issues much like a clogged filter. You’ll gradually lose airflow until your system freezes or halts cooling. You’ll need to call Service Experts Heating & Air Conditioning to take care of the malfunction.

Defective blower motor or relay—A blower motor running at the wrong speed or not turning on at all can cause freezing. It may also be sporadic, starting at top speed and slowing down after it gets too hot. Or a relay can cause it to work one time and not the next. In either state, you will need to contact Service Experts Heating & Air Conditioning to repair the issue.

Booking regular AC maintenance or heat pump maintenance might help you avoid this malfunction. Our professionals will meticulously inspect and clean your system, which often allows us to spot little troubles before they cause major problems.
