Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Longmont. Nearly all of them typically require pro AC repair.

Double-checking the air filter isn’t dirty and airflow isn’t decreased are the only work you can safely handle without professional help. If you need to install a new the filter, you can hasten the defrosting process by switching off the system 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, turn the temp back to normal. If your unit freezes again, call Service Experts Heating & Air Conditioning to take care of the issue.

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

Not enough refrigerant—A frozen system could be a result of a refrigerant leak.

What leads to a leak?

  • Weak solder joints
  • Friction from piping rubbing against an object
  • Cracked valves
  • Loose fittings

How long your unit has been working and the location of the leak play a role in whether you should repair or replace your AC system.

Dusty evaporator coil—As time passes, the evaporator coil becomes dirty and leads to issues resembling a dirty filter. You’ll gradually lose airflow until your equipment freezes or stops cooling. You’ll need to contact Service Experts Heating & Air Conditioning to repair the malfunction.

Defective blower motor or relay—A blower motor going at an inaccurate speed or not working at all can cause freezing. It could also be intermittent, starting at top speed and going slower after it gets warm. Or a relay may force it to work one time and not the next. In either state, you will need to get in touch with Service Experts Heating & Air Conditioning to repair the trouble.

Booking yearly AC maintenance or heat pump maintenance may help you bypass this malfunction. Our Experts will meticulously check and clean your unit, which frequently allows us to spot little problems before they turn into large issues.
