Why is my AC system freezing up?

There are lots of reasons why your AC system freezes up in Voorhees. Almost all of them typically need experienced AC repair.

Checking the air filter is clean and airflow isn’t lowered are the only work you can safely take care of alone. If you need to replace the filter, you can accelerate the thawing 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 has melted.

After the ice melts, move the temperature back to normal. If your equipment freezes again, call Atmostemp Service Experts to correct the malfunction.

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

Insufficient refrigerant—Freezing up can be a result of a refrigerant leak.

What leads to a leak?

  • Fragile solder joints
  • Friction from piping vibrating against something
  • Cracked valves
  • Unsecured fittings

How long your unit 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—Over time, the evaporator coil attracts dirt and causes issues resembling a dusty filter. You’ll gradually lose airflow until your system freezes or halts cooling. You’ll need to get in touch with Atmostemp Service Experts to take care of the problem.

Broken blower motor or relay—A blower motor running at the wrong speed or not running at all can result in freezing. It could also be intermittent, starting at maximum speed and slowing down after it gets too hot. Or a relay might force it to start one time and not the next. In either case, you will need to contact Atmostemp Service Experts to correct the trouble.

Requesting annual AC maintenance or heat pump maintenance may help you avoid this malfunction. Our pros will thoroughly examine and clean your unit, which usually allows us to spot little troubles before they turn into major troubles.
