Why is my AC system freezing up?

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

Making sure the air filter isn’t dusty and airflow isn’t decreased are the only things you can safely fix yourself. If you need to install a new the filter, you can hasten the thawing process by disabling 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 disappears, switch the temp back to normal. If your unit freezes repeatedly, contact Orangutan Home Services to correct the issue.

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

Insufficient refrigerant—Freezing may be caused by a refrigerant leak.

What creates a leak?

  • Fragile solder joints
  • Grating from piping vibrating against an object
  • Cracked valves
  • Slack fittings

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

Filthy evaporator coil—As time passes, the evaporator coil attracts dirt and leads to troubles resembling a dusty filter. You’ll slowly receive lower airflow until your equipment freezes or stops cooling. You’ll need to call Orangutan Home Services to take care of the problem.

Defective blower motor or relay—A blower motor running at an inaccurate speed or not turning on at all can cause freezing. It could also be sporadic, starting at top speed and decelerating after it gets too hot. Or a relay may make it work one time and not the next. In either state, you will need to get in touch with Orangutan Home Services to fix the problem.
