How do I manually open my AC damper?

To open the damper, you should turn the lever at a position where it’s paralleled with the duct. This allows the air to flow through the ducts to its fullest. Then, adjust the lever to a position horizontal to the duct to close it.

Why is my AC unit not turning on?

A loose or frayed wire could also prevent your unit from turning on. Speaking of the thermostat, glitches within the control center of your air conditioner could also pose a problem. Failure to turn on an AC unit that’s blowing warm air are both signs of a thermostat issue. First, make sure your thermostat is calibrated correctly.

What should I do if my air conditioner wont start?

Most central air systems run relatively quiet. You may hear a “swoosh” as the unit turns on and cool air floods from the vents and into your home.

What to do if your air conditioner won’t start?

If you want to test it, set it for a low temperature, so that the AC unit would start right away. Make sure you set it to “cool” and not “heat”! If that doesn’t work, either replace the thermostat’s batteries or look for a dedicated thermostat or AC switch on your circuit breaker.

Why is my air conditioner not working in the summer?
