Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Charlotte. Almost all of them typically need skilled AC repair.

Double-checking the air filter isn’t dusty and airflow isn’t lowered are the only work you can safely take care of without professional help. If you need to install a new the filter, you can speed up the defrosting process by switching off the equipment and switching on the fan. If you have a heat pump, you can move 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, get in touch with Komfort Air to repair the problem.

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

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

What creates a leak?

  • Weak solder joints
  • Grating from piping rubbing against other components
  • Ruptured valves
  • Slack fittings

How long your equipment has been running and the location of the leak determine whether you should repair or replace your AC system.

Dirty evaporator coil—Over time, the evaporator coil becomes dirty and causes troubles resembling a clogged filter. You’ll progressively lose airflow until your system freezes or stops cooling. You’ll need to contact Komfort Air to repair the issue.

Broken blower motor or relay—A blower motor going at an inaccurate speed or not working at all can result in freezing. It might also be irregular, starting at top speed and slowing down after it gets too hot. Or a relay could force it to work one time and not the subsequent time. In either state, you will need to contact Komfort Air to repair the trouble.

Requesting annual AC maintenance or heat pump maintenance can help you avoid this malfunction. Our pros will thoroughly inspect and clean your equipment, which frequently allows us to catch little problems before they become huge problems.
