What is what to do when your air conditioner stops working?

Here's what to do when your air conditioner stops working:

First, Check the Thermostat: Ensure it's set to "Cool" and the temperature is lower than the current room temperature. Make sure the fan is set to "Auto" or "On." Sometimes, a simple setting adjustment is all it takes.

Next, Inspect the Air Filter: A dirty or clogged air filter restricts airflow, causing the AC to work harder and potentially overheat. Replace it with a new one.

Then, Examine the Outdoor Unit: Clear any debris (leaves, branches, grass clippings) from around the unit. Ensure the fins are not bent or damaged. Gently straighten them with a fin comb if necessary.

Check the Circuit Breaker: Look at your electrical panel and see if the breaker for your AC unit has tripped. If so, reset it. If it trips again immediately, there may be a more significant electrical problem.

Look for Ice Buildup: Ice on the evaporator coil (usually located inside the indoor unit) can stop the AC from cooling. Turn off the AC and set the fan to "On" to help melt the ice. Once melted, investigate the cause (usually a refrigerant leak or airflow issue).

If none of these steps work, it's best to Call a Qualified HVAC Technician. There may be a more complex issue, such as a refrigerant leak, compressor failure, or other mechanical problem that requires professional diagnosis and repair. Trying to fix these yourself can be dangerous and may void your warranty.
