Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Jackson. Nearly all of them usually call for professional AC repair.

Checking the air filter isn’t clogged and airflow isn’t decreased are the only things you can safely take care of without professional help. If you need to replace the filter, you can accelerate the defrosting process by disabling the system and switching on the fan. If you have a heat pump, you can switch it to heat mode until the ice has disappeared.

After the ice melts, move settings back to normal. If your equipment freezes again, get in touch with Comfortech Service Experts to correct the malfunction.

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

Insufficient refrigerant—A frozen system could be caused by a refrigerant leak.

What leads to a leak?

  • Fragile solder joints
  • Friction from piping vibrating against other components
  • Broken valves
  • Unsecured fittings

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

Dusty evaporator coil—As time passes, the evaporator coil attracts dirt and creates troubles much like a clogged filter. You’ll slowly receive lower airflow until your system freezes or halts cooling. You’ll need to call Comfortech Service Experts to repair the problem.

Broken blower motor or relay—A blower motor running at the wrong speed or not working at all can cause freezing. It may also be sporadic, starting at top speed and decelerating after it gets too hot. Or a relay could force it to run one time and not the next. In either case, you will need to call Comfortech Service Experts to correct the problem.

Booking regular AC maintenance or heat pump maintenance can help you skip this issue. Our technicians will fully check and clean your equipment, which frequently allows us to spot small problems before they cause major troubles.
