Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Grand Island. Nearly all of them typically require experienced AC repair.

Double-checking the air filter isn’t dirty and airflow isn’t restricted are the only things you can safely take care of on your own. If you need to put in a new the filter, you can hasten the melting process by turning off the system and turning 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 a second time, call McElroy Service Experts to correct the problem.

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

Low refrigerant—Freezing could be created by a refrigerant leak.

What leads to a leak?

  • Fragile solder joints
  • Resistance from piping rubbing against an object
  • Ruptured valves
  • Unsecured fittings

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

Filthy evaporator coil—Over time, the evaporator coil becomes dirty and leads to issues resembling a clogged filter. You’ll slowly receive lower airflow until your system freezes or stops cooling. You’ll need to contact McElroy Service Experts to take care of the issue.

Defective blower motor or relay—A blower motor going at an inaccurate speed or not turning on at all can cause freezing. It could also be irregular, starting at maximum speed and slowing down after it heats up. Or a relay can force it to start one time and not the following time. In either case, you will need to contact McElroy Service Experts to repair the trouble.

Booking annual AC maintenance or heat pump maintenance can help you skip this issue. Our professionals will thoroughly check and clean your unit, which frequently allows us to spot small problems before they turn into major issues.
