Why is my AC system freezing up?

There are many reasons why your AC system freezes up in San Antonio. Most all of them typically require pro AC repair.

Checking the air filter is clean and airflow isn’t restricted are the only tasks you can safely handle without professional help. If you need to put in a new the filter, you can hasten the melting process by turning off the system 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 disappears, turn settings back to normal. If your system freezes a second time, contact San Antonio Air Service Experts to take care of the problem.

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

Low refrigerant—Freezing can be created by a refrigerant leak.

What causes a leak?

  • Weak solder joints
  • Friction from piping vibrating against something
  • Cracked valves
  • Loose fittings

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

Dirty evaporator coil—As time passes, the evaporator coil attracts dirt and causes issues resembling a clogged filter. You’ll progressively lose airflow until your equipment freezes or quits cooling. You’ll need to get in touch with San Antonio Air Service Experts to fix the problem.

Broken blower motor or relay—A blower motor working at an inaccurate speed or not running at all can create freezing. It might also be intermittent, going at top speed and going slower after it heats up. Or a relay may force it to work one time and not the subsequent time. In either situation, you will need to contact San Antonio Air Service Experts to fix the trouble.

Requesting yearly AC maintenance or heat pump maintenance can help you bypass this issue. Our pros will comprehensively inspect and clean your system, which usually allows us to catch small troubles before they become large issues.
