Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Memphis. Most all of them usually require pro AC repair.

Checking the air filter is clean and airflow isn’t decreased are the only things you can safely take care of alone. If you need to install a new the filter, you can speed up the defrosting process by disabling the system and using the fan. If you have a heat pump, you can turn it to heat mode until the ice has melted.

After the ice melts, move the temp back to normal. If your unit freezes repeatedly, call Service Experts Heating & Air Conditioning to fix the problem.

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

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

What causes a leak?

  • Weak solder joints
  • Friction from piping rubbing against other components
  • Broken valves
  • Loose fittings

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

Dirty evaporator coil—As time passes, the evaporator coil becomes dirty and causes problems resembling a dusty filter. You’ll gradually lose airflow until your system freezes or halts cooling. You’ll need to contact Service Experts Heating & Air Conditioning to repair the malfunction.

Malfunctioning blower motor or relay—A blower motor working at an inaccurate speed or not turning on at all can result in freezing. It can also be irregular, going at top speed and decelerating after it gets warm. Or a relay might cause it to work one time and not the subsequent time. In either state, you will need to contact Service Experts Heating & Air Conditioning to fix the trouble.

Requesting yearly AC maintenance or heat pump maintenance can help you bypass this issue. Our professionals will comprehensively inspect and clean your system, which frequently allows us to spot little issues before they cause large troubles.
