Why is my AC system freezing up?

There are lots of reasons why your AC system freezes up in Louisville. Nearly all of them frequently call for skilled AC repair.

Making sure the air filter isn’t dirty and airflow isn’t lowered are the only things you can safely fix without professional help. If you need to put in a new the filter, you can speed up the thawing process by turning off the unit and using the fan. If you have a heat pump, you can turn it to heat mode until the ice is gone.

After the ice is gone, switch settings back to normal. If your equipment freezes again, get in touch with Becht/Givens Service Experts to correct the problem.

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

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

What creates a leak?

  • Fragile solder joints
  • Grating from piping vibrating against an object
  • Cracked valves
  • Slack fittings

How long your system has been working and the spot 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 leads to issues much like a dusty filter. You’ll slowly lose airflow until your equipment freezes or halts cooling. You’ll need to get in touch with Becht/Givens Service Experts to repair the problem.

Broken blower motor or relay—A blower motor going at an inaccurate speed or not turning on at all can result in freezing. It may also be irregular, running at full speed and slowing down after it gets warm. Or a relay can make it run one time and not the next. In either state, you will need to call Becht/Givens Service Experts to correct the trouble.

Scheduling regular AC maintenance or heat pump maintenance might help you bypass this issue. Our professionals will thoroughly inspect and clean your system, which usually allows us to discover small issues before they become huge problems.
