Why is my AC system freezing up?

There are a lot of reasons why your AC system freezes up.

Double-checking the air filter isn’t dirty and airflow isn’t decreased are the only work you can safely take care of yourself. If you need to put in a new the filter, you can hasten the melting process by turning off the unit and turning on the fan. If you have a heat pump, you can turn it to heat mode until the ice has melted.

After the ice disappears, move the temp back to normal. If your system freezes repeatedly, get in touch with Broad Ripple Service Experts to repair the malfunction.

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

Not enough refrigerant—Freezing up can be caused by a refrigerant leak.

What leads to a leak?

  • Weak solder joints
  • Resistance from piping vibrating against something
  • Cracked valves
  • Loose fittings

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

Filthy evaporator coil—Over time, the evaporator coil attracts dirt and leads to problems resembling a dirty filter. You’ll gradually get lower airflow until your unit freezes or quits cooling. You’ll need to contact Broad Ripple Service Experts to repair the problem.

Defective blower motor or relay—A blower motor running at an incorrect speed or not running at all can create freezing. It could also be sporadic, running at full speed and slowing down after it heats up. Or a relay may make it work one time and not the following time. In either state, you will need to contact Broad Ripple Service Experts to fix the problem.

Scheduling annual AC maintenance could help you avoid this problem. Our professionals will thoroughly examine and clean your unit, which often allows us to find little issues before they become major issues.
