Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Gaithersburg. Nearly all of them frequently call for skilled AC repair.

Checking the air filter isn’t dusty and airflow isn’t lowered are the only tasks you can safely take care of 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 move it to heat mode until the ice has disappeared.

After the ice melts, switch the temperature back to normal. If your equipment freezes repeatedly, get in touch with Parker Pearce Service Experts to take care of the problem.

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

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

What leads to a leak?

  • Weak solder joints
  • Friction from piping vibrating against an object
  • Cracked valves
  • Unsecured fittings

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

Filthy evaporator coil—Throughout the seasons, the evaporator coil attracts dirt and causes problems resembling a clogged filter. You’ll gradually lose airflow until your system freezes or quits cooling. You’ll need to get in touch with Parker Pearce Service Experts to repair the malfunction.

Malfunctioning blower motor or relay—A blower motor going at an inaccurate speed or not working at all can lead to freezing. It might also be irregular, starting at maximum speed and decelerating after it gets warm. Or a relay might force it to start one time and not the subsequent time. In either state, you will need to get in touch with Parker Pearce Service Experts to repair the problem.

Scheduling yearly AC maintenance or heat pump maintenance can help you bypass this issue. Our technicians will meticulously inspect and clean your equipment, which typically allows us to catch small issues before they become huge problems.
