There are many reasons why your AC system freezes up.
Double-checking the air filter isn’t clogged and airflow isn’t decreased are the only work you can safely take care of yourself. If you need to put in a new the filter, you can accelerate the defrosting process by turning off the system and turning on the fan. If you have a heat pump, you can move it to heat mode until the ice has melted.
After the ice melts, switch the temp back to normal. If your equipment freezes a second time, contact Stevenson Service Experts to correct the malfunction.
Here are a couple other other reasons why your equipment may be freezing up.
Not enough refrigerant—Freezing may be created by a refrigerant leak.
What creates a leak?
- Weakened solder joints
- Grating from piping vibrating against something
- Ruptured 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—As time passes, the evaporator coil attracts dirt and leads to problems resembling a dirty filter. You’ll progressively lose airflow until your system freezes or stops cooling. You’ll need to call Stevenson Service Experts to fix the issue.
Malfunctioning blower motor or relay—A blower motor going at an inaccurate speed or not turning on at all can cause freezing. It may also be sporadic, starting at top speed and going slower after it heats up. Or a relay may cause it to work one time and not the subsequent time. In either situation, you will need to call Stevenson Service Experts to repair the problem.
