Why is my AC system freezing up?

There are lots of reasons why your AC system freezes up in Sharonville. Nearly all of them typically need professional AC repair.

Double-checking the air filter isn’t dirty and airflow isn’t decreased are the only tasks you can safely fix on your own. If you need to replace the filter, you can hasten the defrosting process by switching off the system 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 is gone, move settings back to normal. If your system freezes again, contact Knochelmann Service Experts to correct the problem.

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

Not enough refrigerant—Freezing up could be a result of a refrigerant leak.

What creates a leak?

  • Fragile solder joints
  • Grating from piping jarring against other components
  • Broken valves
  • Slack fittings

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

Dusty evaporator coil—Throughout the seasons, the evaporator coil gets dirty and leads to issues resembling a clogged filter. You’ll gradually lose airflow until your equipment freezes or halts cooling. You’ll need to get in touch with Knochelmann Service Experts to fix the problem.

Defective blower motor or relay—A blower motor working at the wrong speed or not working at all can result in freezing. It could also be sporadic, starting at maximum speed and going slower after it gets too hot. Or a relay could force it to start one time and not the next. In either situation, you will need to call Knochelmann Service Experts to repair the problem.

Requesting yearly AC maintenance or heat pump maintenance could help you bypass this malfunction. Our pros will meticulously examine and clean your system, which usually allows us to notice minor issues before they become major problems.
