First, check to ensure that the thermostat is properly set and has power. If the thermostat is on, but the AC unit still won’t turn on, it could be due to a tripped circuit breaker or a blown fuse. You’ll need to reset the breaker or replace the fuse to restore power to the unit.

Additionally, your AC unit may not turn on if there’s an issue with the compressor or fan motor. If you believe this to be the case, you should contact a professional for repairs.

Check to see if anything is obstructing the blower fan. If the fan is obstructed, it will run less efficiently and may make strange noises. Additionally, strange noises could be an indication that the furnace’s motor or bearings are starting to fail.


If you hear any loud banging or squealing noises coming from your furnace, it’s best to shut it off and call a professional for repairs.

HVAC systems are complex and require special tools and training to diagnose and repair properly. Additionally, attempting to repair an HVAC system yourself could void the warranty or cause further damage. Lastly, some HVAC problems may be caused by an issue with the electrical system, which a certified technician in Germantown, MD should only handle.
