Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Albany. Nearly all of them frequently need skilled AC repair.

Making sure the air filter is clean and airflow isn’t decreased are the only tasks you can safely fix on your own. If you need to replace the filter, you can speed up the defrosting 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 is gone.

After the ice is gone, turn the temperature back to normal. If your system freezes again, contact Roland J. Down Service Experts to repair the problem.

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

Low refrigerant—A frozen system could be created by a refrigerant leak.

What creates a leak?

  • Weak solder joints
  • Friction from piping rubbing against an object
  • Cracked valves
  • Unsecured fittings

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

Dirty evaporator coil—As time passes, the evaporator coil attracts dirt and creates problems much like a dusty filter. You’ll progressively lose airflow until your system freezes or stops cooling. You’ll need to call Roland J. Down Service Experts to fix the problem.

Defective blower motor or relay—A blower motor working at the wrong speed or not turning on at all can cause freezing. It might also be intermittent, going at top speed and going slower after it heats up. Or a relay might force it to work one time and not the next. In either state, you will need to contact Roland J. Down Service Experts to correct the issue.

Scheduling annual AC maintenance or heat pump maintenance could help you avoid this issue. Our professionals will thoroughly inspect and clean your equipment, which often allows us to notice small problems before they become huge problems.
