Why is my AC system freezing up?

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

Double-checking the air filter isn’t dirty and airflow isn’t restricted are the only tasks you can safely fix alone. If you need to install a new the filter, you can accelerate the thawing process by disabling the unit and turning on the fan. If you have a heat pump, you can move it to heat mode until the ice has disappeared.

After the ice disappears, turn settings back to normal. If your unit freezes repeatedly, get in touch with Strand Brothers Service Experts to take care of the issue.

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

Low refrigerant—A frozen system may be caused by a refrigerant leak.

What creates a leak?

  • Weakened solder joints
  • Resistance from piping jarring against other parts
  • Broken valves
  • Slack 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—Over time, the evaporator coil attracts dirt and creates issues much like a dusty filter. You’ll slowly get lower airflow until your system freezes or halts cooling. You’ll need to call Strand Brothers Service Experts to fix the problem.

Broken blower motor or relay—A blower motor going at the wrong speed or not running at all can result in freezing. It can also be sporadic, starting at top speed and decelerating after it gets warm. Or a relay might make it run one time and not the following time. In either state, you will need to contact Strand Brothers Service Experts to repair the problem.

Booking yearly AC maintenance or heat pump maintenance can help you bypass this issue. Our technicians will fully inspect and clean your equipment, which usually allows us to discover little problems before they become major troubles.
