Why is my AC system freezing up?

There are a lot of reasons why your AC system freezes up in Kingston. Nearly all of them typically require skilled AC repair.

Double-checking the air filter is clean and airflow isn’t decreased are the only tasks you can safely handle alone. If you need to install a new the filter, you can speed up the melting process by disabling the unit and using the fan. If you have a heat pump, you can turn it to heat mode until the ice has disappeared.

After the ice disappears, switch the temperature back to normal. If your equipment freezes a second time, get in touch with Service Experts Heating & Air Conditioning to correct the problem.

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

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

What creates a leak?

  • Weakened solder joints
  • Friction from piping vibrating against other parts
  • Cracked valves
  • Loose fittings

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

Filthy evaporator coil—Throughout the seasons, the evaporator coil gets dirty and leads to troubles similar to a clogged filter. You’ll gradually get lower airflow until your system freezes or halts cooling. You’ll need to contact Service Experts Heating & Air Conditioning to repair the problem.

Defective blower motor or relay—A blower motor working at an incorrect speed or not turning on at all can create freezing. It may also be irregular, starting at maximum speed and decelerating after it gets warm. Or a relay could make it start one time and not the following time. In either case, you will need to contact Service Experts Heating & Air Conditioning to correct the problem.

Booking yearly AC maintenance or heat pump maintenance might help you bypass this issue. Our professionals will thoroughly examine and clean your system, which typically allows us to spot little troubles before they become huge problems.
