Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Hilton Head Island. Almost all of them frequently require experienced AC repair.

Double-checking the air filter isn’t dirty and airflow isn’t decreased are the only tasks you can safely handle alone. If you need to replace the filter, you can speed up the defrosting process by turning off the system and using the fan. If you have a heat pump, you can switch it to heat mode until the ice has disappeared.

After the ice is gone, switch the temp back to normal. If your system freezes a second time, contact Epperson Service Experts to correct the problem.

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

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

What causes a leak?

  • Fragile solder joints
  • Friction from piping vibrating against other components
  • Ruptured valves
  • Loose fittings

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

Dirty evaporator coil—As time passes, the evaporator coil attracts dirt and leads to issues resembling a dirty filter. You’ll slowly receive lower airflow until your system freezes or halts cooling. You’ll need to get in touch with Epperson Service Experts to repair the issue.

Defective blower motor or relay—A blower motor working at the wrong speed or not running at all can result in freezing. It can also be irregular, starting at top speed and going slower after it gets warm. Or a relay may make it start one time and not the subsequent time. In either case, you will need to call Epperson Service Experts to repair the trouble.

Requesting yearly AC maintenance or heat pump maintenance can help you skip this malfunction. Our Experts will comprehensively examine and clean your unit, which often allows us to pinpoint small issues before they cause huge problems.
