If you are wondering what to do when your AC suddenly stops working, start by checking the simple issues yourself before calling a professional. Also, make sure the AC has power and the switchboard or circuit is working. Sometimes the problem is as simple as a tripped switch or power outage.
What to Do if Your AC Stops Working?
Dirty Filters
Start by looking at the air filters. Dirty filters block air and stop the AC from cooling properly.
Turn off the AC, remove the filters, and clean them with a soft brush or wash them with water.
Let them dry completely before putting them back. This simple step often fixes the problem.
Leaking Refrigerant/Coolant
Check the refrigerant or coolant. If the AC makes hissing or bubbling sounds, or if you see ice on the outdoor unit, the refrigerant might be low or leaking.
Do not try to fix this yourself. Call a professional to refill the gas and repair any leaks. If these steps do not solve the problem, contact a professional AC repair technician immediately. They can inspect and fix the AC safely.
Malfunctioning Compressor
The compressor is another part that can cause the AC to stop working.
If the AC blows hot air, the outdoor unit shakes, makes strange noises, or does not turn on at all, the compressor might be damaged.
A broken compressor usually needs replacement, so contact an AC service expert.
Thermostat Setting
Check the thermostat inside your home. If it is set incorrectly, the AC will not cool properly. Set the thermostat to “auto” mode.
This helps the AC detect the room temperature and automatically adjust the fan and cooling.
The best way to fix a problem with your AC is to hire a professional. If you try to repair it yourself, you might accidentally damage the AC further. I hope you know now what to do when your AC suddenly stops working.
