Why is my AC system freezing up?

There are many reasons why your AC system freezes up.

Double-checking the air filter isn’t clogged and airflow isn’t lowered are the only tasks you can safely handle yourself. If you need to replace the filter, you can hasten the melting process by turning off the equipment and turning 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, move the temperature back to normal. If your system freezes a second time, contact Peachtree Service Experts to take care of the issue.

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

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

What causes a leak?

  • Fragile solder joints
  • Grating from piping rubbing against an object
  • Broken valves
  • Unsecured fittings

How long your equipment has been running and the spot of the leak play a part in whether you should repair or replace your AC system.

Dirty evaporator coil—Over time, the evaporator coil gets dirty and creates troubles similar to a dusty filter. You’ll gradually receive lower airflow until your unit freezes or halts cooling. You’ll need to call Peachtree Service Experts to repair the problem.

Defective blower motor or relay—A blower motor working at the wrong speed or not working at all can create freezing. It may also be irregular, running at maximum speed and going slower after it heats up. Or a relay can make it run one time and not the subsequent time. In either state, you will need to get in touch with Peachtree Service Experts to repair the trouble.

Booking annual AC maintenance could help you skip this malfunction. Our professionals will meticulously check and clean your unit, which frequently allows us to spot small troubles before they turn into major troubles.
