What is wrong with my AC?
Many different things may have gone wrong with your central air conditioning system that will cause it to refuse to turn on. This is why it's crucial to have skilled HVAC technicians investigate the problem: they will narrow down the possible causes and make sure the system receives the correct repair work.
One common reason for an AC to fail to turn on is a malfunction in the thermostat. If the thermostat loses its connection to the cooling system, the air conditioner will not know when it turn on and won't respond to any programming. Thankfully, this is an easy issue for technicians to repair.
The air conditioner may have a broken blower fan motor. In this case, the compressor may still run (go outside and check if the outdoor unit is making noise), but no air will move across the evaporator coils and get sent into the ventilation system. Usually, repair technicians will need to replace the motors.
Other electrical faults may be at the heart of the problem. If the air conditioner trips circuit breakers instead of coming on, repair experts will have to see if there is a voltage mismatch in the system. Loose electrical connections may also be at fault.
There is also the possibility that the AC has reached the end of its lifespan and needs a replacement. HVAC professionals will be able to give you an honest answer about whether an aging air conditioner will still benefit from repairs or if the time has arrived when it needs to be retired.
