There are many reasons why your AC system freezes up in San Antonio. Most all of them typically call for professional AC repair.
Making sure the air filter is clean and airflow isn’t restricted are the only tasks you can safely fix alone. If you need to replace the filter, you can accelerate the defrosting process by switching 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, move the temperature back to normal. If your equipment freezes a second time, call Aramendia Plumbing, Heating and Air to correct the problem.
Here are a few other reasons why your unit could be freezing up.
Insufficient refrigerant—Freezing may be created by a refrigerant leak.
What creates a leak?
- Fragile solder joints
- Resistance from piping jarring against something
- Broken valves
- Slack fittings
How long your unit has been installed and the location of the leak play a role in whether you should repair or replace your AC system.
Filthy evaporator coil—Over time, the evaporator coil attracts dirt and creates troubles similar to a clogged filter. You’ll progressively lose airflow until your equipment freezes or halts cooling. You’ll need to get in touch with Aramendia Plumbing, Heating and Air to fix the problem.
Broken blower motor or relay—A blower motor running at an inaccurate speed or not running at all can cause freezing. It might also be sporadic, running at full speed and going slower after it gets warm. Or a relay may make it work one time and not the following time. In either case, you will need to get in touch with Aramendia Plumbing, Heating and Air to correct the problem.
Scheduling annual AC maintenance or heat pump maintenance may help you bypass this malfunction. Our pros will comprehensively check and clean your system, which typically allows us to catch minor problems before they become huge problems.
