My Air Conditioner Won’t Turn On!

If your air conditioner won’t turn on and you need AC repair services in Northern Virginia, call the expert HVAC technicians at John Nugent & Sons.

Reasons an Air Conditioner Won’t Turn On

Let’s take a look possible reasons your AC may not be turning on:

Thermostat

First, check your thermostat to make sure that it seems to be operating correctly—and that it is set for cooling. This sounds obvious, but someone in your home may have accidentally changed the settings. If that doesn’t help, your thermostat may have a connectivity problem. If it’s wired, it could mean that there is faulty wiring somewhere between the thermostat device and the AC unit itself. If it’s wireless, the signal may be getting blocked by some material.

Electrical Problem

Of course, you AC needs electricity to operate—so if your AC unit won’t turn on, it may be due to an electrical malfunction of some type. First, check that you haven’t blown a fuse or tripped a circuit breaker. If that doesn’t help, there are numerous possible reasons. The unit may have a bad capacitor or a damaged wire in the electrical supply line. If you hear buzzing, it might be a sign the unit has a dangerous electrical arcing issue.

Other Considerations

If your AC unit won’t turn on, it may have just called it quits. The compressor motor may have burned out—or there may be another serious problem with the mechanical system. Consider AC replacement as a viable option. There is an excellent AC tax credit currently available for the purchase and installation of an efficient unit.
