There can be a few reasons why your air conditioning won’t run: an overloaded circuit breaker, inaccurate thermostat settings, a turned-off switch, or an overflowing condensate drain pan.
Tripped Circuit Breaker
Your cooling won’t turn on when you have an overloaded breaker.
To see if one has blown, go to your house’s main electrical panel. You can locate this gray box on the wall in the basement, garage, or closet.
- Confirm your hands and feet are free of moisture before you work on the panel or breakers.
- Look for the breaker identified “AC” and make sure it’s in the “on” position. If it’s tripped, the lever will be in the “off” position.
- Steadily shift the lever back to the “on” location. If it instantaneously flips again, don’t reset it, and get in touch with us at (832) 957-9332. A fuse that keeps tripping might mean your residence has an electrical problem.
Incorrect Thermostat Settings
If your thermostat isn’t telling your AC to work, it won’t activate.
The most important point is ensuring it’s switched to “cool” and not “heat.” Otherwise, your AC might not turn on. You may also receive heated air blowing from vents because the furnace is on instead.
If you have a regular thermostat:
- Replace the batteries if the readout is blank. If the monitor is showing scrambled numbers, buy a new thermostat.
- Check the proper program is displaying. If you can’t alter it, override it by lowering the temperature and hitting the “hold” button. This will make your AC start if scheduling is wrong.
- Test setting the thermostat 5 degrees below the room’s temperature. Your AC won’t work if the thermostat is set to the same as the space’s temperature.
Once your thermostat is calibrated properly, you should start getting cool air quickly.
If you rely on a smart thermostat, including ones made by Nest, Ecobee, Lux, Honeywell, or Bosch, check the manufacturer’s website for assistance. If you’re still having problems, call us at (832) 957-9332 for assistance.
Your system usually has a power-cutting device near its condenser. This lever is commonly in a metal box attached to your house. If your AC has recently been tuned up, the lever may have accidentally been turned off.
Overflowing Condensate Drain Pan
Condensate drain pans keep the surplus condensation your equipment removes from the air. This pan can be situated either below or in your furnace or air handler.
When there’s a blockage or blocked drain, water can become concentrated and initiate a safety setting to turn off your air conditioner.
If your pan involves a PVC pipe or drain, you can clear the additional condensation with a custom pan-cleaning tab. You can buy these tabs at a home improvement or hardware retailer.
If your pan includes a pump, find the float switch. If the lever is “up” and there’s moisture in the pan, you could need to get a new pump. Call us at (832) 957-9332 for help.
