Why is my AC system freezing up?

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

Double-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 thawing process by turning off the equipment and switching on the fan. If you have a heat pump, you can turn it to heat mode until the ice has disappeared.

After the ice melts, switch the temperature back to normal. If your unit freezes again, get in touch with Service Experts Heating & Air Conditioning to fix the issue.

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

Insufficient refrigerant—Freezing up could be caused by a refrigerant leak.

What creates a leak?

  • Fragile solder joints
  • Resistance 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.

Dusty evaporator coil—Over time, the evaporator coil gets dirty and causes troubles resembling a clogged filter. You’ll gradually lose airflow until your system freezes or quits cooling. You’ll need to call Service Experts Heating & Air Conditioning to repair the issue.

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

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