Why is my AC system freezing up?

There are lots of reasons why your AC system freezes up in Indianapolis. Nearly all of them typically need pro AC repair.

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 accelerate the melting process by turning off the equipment 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 melts, move the temperature back to normal. If your system freezes a second time, call Broad Ripple Service Experts to repair the malfunction.

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

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

What leads to a leak?

  • Weak solder joints
  • Grating from piping rubbing against something
  • Cracked valves
  • Loose fittings

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

Filthy evaporator coil—Over time, the evaporator coil gets dirty and creates problems resembling a dirty filter. You’ll gradually receive lower airflow until your equipment freezes or halts cooling. You’ll need to contact Broad Ripple Service Experts to take care of the problem.

Defective blower motor or relay—A blower motor running at an inaccurate 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 could make it work one time and not the following time. In either situation, you will need to contact Broad Ripple Service Experts to repair the problem.

Scheduling annual AC maintenance or heat pump maintenance could help you avoid this problem. Our professionals will meticulously check and clean your unit, which often allows us to pinpoint minor issues before they become major issues.
