Why is my AC system freezing up?

There are lots of reasons why your AC system freezes up in Austin. Most all of them usually call for skilled AC repair.

Checking the air filter is clean and airflow isn’t lowered are the only tasks you can safely handle alone. If you need to install a new the filter, you can speed up the defrosting process by switching off the unit and switching on the fan. If you have a heat pump, you can turn it to heat mode until the ice has melted.

After the ice is gone, switch the temperature back to normal. If your system freezes a second time, contact Strand Brothers Service Experts to correct the problem.

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

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

What causes a leak?

  • Fragile solder joints
  • Resistance from piping rubbing against an object
  • Broken valves
  • Slack fittings

How long your equipment has been working and the location of the leak determine whether you should repair or replace your AC system.

Dirty evaporator coil—Over time, the evaporator coil attracts dirt and leads to troubles much like a dusty filter. You’ll slowly lose airflow until your system freezes or stops cooling. You’ll need to get in touch with Strand Brothers Service Experts to take care of the malfunction.

Malfunctioning blower motor or relay—A blower motor running at an incorrect speed or not working at all can create freezing. It might also be intermittent, going at full speed and decelerating after it heats up. Or a relay could cause it to run one time and not the following time. In either case, you will need to call Strand Brothers Service Experts to repair the problem.

Booking annual AC maintenance or heat pump maintenance might help you skip this issue. Our Experts will fully check and clean your unit, which usually allows us to catch little problems before they turn into huge issues.
