Why is my AC system freezing up?

There are many reasons why your AC system freezes up.

Checking the air filter isn’t clogged and airflow isn’t lowered are the only things you can safely handle without professional help. If you need to install a new the filter, you can speed up the melting 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 is gone.

After the ice melts, switch the temperature back to normal. If your unit freezes again, get in touch with Midway Services to take care of the issue.

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

Low refrigerant—Freezing may be created by a refrigerant leak.

What causes a leak?

  • Weakened solder joints
  • Friction from piping vibrating against something
  • Broken valves
  • Loose fittings

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

Filthy evaporator coil—Throughout the seasons, the evaporator coil attracts dirt and causes troubles similar to a clogged filter. You’ll slowly get lower airflow until your system freezes or halts cooling. You’ll need to contact Midway Services to repair the problem.

Broken blower motor or relay—A blower motor working at the wrong speed or not turning on at all can lead to freezing. It may also be intermittent, running at top speed and decelerating after it gets warm. Or a relay could make it run one time and not the following time. In either state, you will need to contact Midway Services to correct the issue.

Scheduling regular AC maintenance could help you avoid this malfunction. Our techs will comprehensively examine and clean your unit, which frequently allows us to locate small problems before they become major troubles.
