Why is my AC system freezing up?

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

Double-checking the air filter isn’t dusty and airflow isn’t decreased are the only tasks you can safely take care of alone. If you need to replace the filter, you can accelerate the melting process by turning off the unit and using the fan. If you have a heat pump, you can switch it to heat mode until the ice is gone.

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

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

Insufficient refrigerant—A frozen system may be caused by a refrigerant leak.

What leads to a leak?

  • Weak solder joints
  • Friction from piping rubbing against other components
  • Cracked valves
  • Slack 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 halts cooling. You’ll need to get in touch with Parker Pearce Service Experts to repair the issue.

Broken blower motor or relay—A blower motor going at an incorrect speed or not turning on at all can cause freezing. It can also be irregular, starting at maximum speed and going slower 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 call Parker Pearce Service Experts to repair the problem.

Scheduling yearly AC maintenance or heat pump maintenance may 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 major problems.
