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 typically require experienced AC repair.

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 melting process by turning off the system and using the fan. If you have a heat pump, you can move it to heat mode until the ice is gone.

After the ice is gone, switch the temperature back to normal. If your system freezes repeatedly, contact Epperson Service Experts to correct the problem.

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

Not enough refrigerant—Freezing could be a result of a refrigerant leak.

What creates a leak?

  • Weakened solder joints
  • Friction from piping rubbing against an object
  • Cracked valves
  • Loose fittings

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

Dirty evaporator coil—Throughout the seasons, the evaporator coil gets dirty and creates issues much like a dirty filter. You’ll progressively get 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 might also be irregular, starting at top speed and going slower after it gets too hot. Or a relay could force it to start one time and not the subsequent time. In either case, you will need to call Epperson Service Experts to repair the trouble.

Booking regular AC maintenance or heat pump maintenance may help you bypass this issue. Our techs will comprehensively examine and clean your equipment, which often allows us to find small issues before they cause major problems.
