There are many reasons why your AC system freezes up.
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 defrosting 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 several other reasons why your equipment might be freezing up.
Low refrigerant—Freezing can be a result of a refrigerant leak.
What creates a leak?
- Weak solder joints
- Friction from piping vibrating against something
- Ruptured valves
- Loose fittings
How long your equipment 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—As time passes, the evaporator coil attracts dirt and causes issues much like a clogged filter. You’ll slowly lose airflow until your equipment freezes or quits cooling. You’ll need to call San Antonio Air Service Experts to fix the problem.
Broken blower motor or relay—A blower motor going at an incorrect speed or not running at all can create freezing. It can also be intermittent, running at top speed and decelerating after it heats up. Or a relay may make it run one time and not the subsequent time. In either situation, you will need to contact San Antonio Air Service Experts to fix the issue.
