Why is my AC system freezing up?

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

Checking the air filter is clean and airflow isn’t lowered are the only tasks you can safely fix yourself. If you need to put in a new the filter, you can speed up the thawing process by turning off the equipment and switching on the fan. If you have a heat pump, you can turn it to heat mode until the ice has melted.

After the ice melts, move settings back to normal. If your unit freezes repeatedly, call D.A. Bennett Service Experts to fix the issue.

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

Insufficient refrigerant—Freezing up could be created by a refrigerant leak.

What causes a leak?

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

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

Dusty evaporator coil—As time passes, the evaporator coil becomes dirty and causes troubles much like a clogged filter. You’ll progressively get lower airflow until your unit freezes or halts cooling. You’ll need to contact D.A. Bennett Service Experts to repair the malfunction.

Malfunctioning blower motor or relay—A blower motor going at the wrong speed or not working at all can cause freezing. It may also be intermittent, going at maximum speed and decelerating after it heats up. Or a relay can cause it to run one time and not the subsequent time. In either state, you will need to get in touch with D.A. Bennett Service Experts to fix the issue.
