Why is my AC system freezing up?

There are lots of reasons why your AC system freezes up.

Checking the air filter isn’t dirty and airflow isn’t lowered are the only things you can safely handle alone. If you need to replace the filter, you can hasten the thawing process by disabling the equipment and turning on the fan. If you have a heat pump, you can switch it to heat mode until the ice has disappeared.

After the ice disappears, switch the temperature back to normal. If your equipment freezes repeatedly, get in touch with Service Experts Heating & Air Conditioning to fix the issue.

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

Low refrigerant—Freezing can be caused by a refrigerant leak.

What causes a leak?

  • Fragile solder joints
  • Resistance from piping rubbing against other components
  • Broken valves
  • Slack fittings

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

Dirty evaporator coil—As time passes, the evaporator coil attracts dirt and causes issues resembling a clogged filter. You’ll gradually lose airflow until your equipment freezes or stops cooling. You’ll need to contact Service Experts Heating & Air Conditioning to take care of the problem.

Broken blower motor or relay—A blower motor going at the wrong speed or not running at all can create freezing. It can also be irregular, going at full speed and decelerating after it heats up. Or a relay may force it to run one time and not the subsequent time. In either case, you will need to call Service Experts Heating & Air Conditioning to correct the problem.

Booking annual AC maintenance may help you bypass this malfunction. Our pros will thoroughly inspect and clean your equipment, which usually allows us to locate little troubles before they cause huge troubles.
