Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Tulsa. Nearly all of them frequently require pro AC repair.

Checking the air filter isn’t dusty and airflow isn’t restricted are the only work you can safely handle without professional help. If you need to replace the filter, you can accelerate the defrosting process by turning off the unit and using the fan. If you have a heat pump, you can turn it to heat mode until the ice is gone.

After the ice is gone, move the temp back to normal. If your system freezes a second time, call Jack Nelson Service Experts to fix the problem.

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

Insufficient refrigerant—Freezing up can be created by a refrigerant leak.

What leads to a leak?

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

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

Dusty evaporator coil—As time passes, the evaporator coil attracts dirt and leads to problems similar to a clogged filter. You’ll gradually receive lower airflow until your unit freezes or stops cooling. You’ll need to call Jack Nelson Service Experts to fix the issue.

Malfunctioning blower motor or relay—A blower motor working at an incorrect speed or not turning on at all can cause freezing. It could also be sporadic, running at maximum 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 repair the problem.

Scheduling yearly AC maintenance or heat pump maintenance could help you avoid this malfunction. Our techs will thoroughly check and clean your unit, which frequently allows us to catch little troubles before they become large problems.
