Why is my AC system freezing up?

There are many reasons why your AC system freezes up.

Checking the air filter isn’t dusty and airflow isn’t restricted are the only things you can safely handle without professional help. If you need to replace 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 disappeared.

After the ice is gone, turn the temp back to normal. If your system freezes repeatedly, call Jack Nelson Service Experts to repair the problem.

Here are a few other reasons why your equipment could be freezing up.

Insufficient refrigerant—A frozen system can be a result of a refrigerant leak.

What leads to a leak?

  • Weak solder joints
  • Friction from piping vibrating against other parts
  • Broken valves
  • Slack fittings

How long your equipment 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 problems similar to a clogged filter. You’ll gradually get lower airflow until your unit freezes or stops cooling. You’ll need to call Jack Nelson Service Experts to fix the malfunction.

Broken blower motor or relay—A blower motor working at an incorrect speed or not turning on at all can lead to freezing. It could also be sporadic, running at top speed and going slower after it gets warm. Or a relay can make it start one time and not the next. In either case, you will need to get in touch with Jack Nelson Service Experts to fix the problem.

Scheduling regular AC maintenance could help you avoid this issue. Our techs will thoroughly examine and clean your unit, which frequently allows us to notice minor troubles before they become large problems.
