As we enter into the warmer seasons, it is the perfect time to make any home repairs that may be needed. This is especially true for your HVAC system. Don’t weather the Arizona summer heat with a faulty or broken AC unit. If you have been wondering “why won’t my central air conditioner turn on in Phoenix?”, here are a few reasons why.
If your AC unit won’t turn on, one place to check first is the circuit breakers. The circuit breakers are essential for protecting the AC unit from damage or fire caused by an overload or short circuit. The breakers do this by interrupting or stopping current flow when too much current is flowing through it. It is possible that your AC unit is not turning on because the breaker tripped which would prevent electrical currents from powering the system.
To determine if the circuit breaker is the source of your problem, go to your electrical panel and look for any tripped breakers. Switch the tripped breaker off then switch it back on again. If the breaker trips again immediately or soon after resetting it, do not try resetting it again. Instead, contact a professional like Hays Cooling and Heating for expert Phoenix AC repair.
Another common culprit that could be responsible for your AC unit not turning on is faulty AC wiring. If your circuit breakers and fuses go out regularly, this could be a sign of faulty wiring. Bad wiring is very dangerous and arguably the most common cause of house and apartment fires in the United States. If you have faulty wires, or if your AC unit fuse blew, you should seek repairs, especially in older AC unit models, as soon as possible to avoid any safety hazards.
When replacing the fuse or breaker, do not replace it with a higher rating unit. This is very dangerous because the wiring that is already installed in your unit will not match the higher rating fuse or circuit. If installed like this, the likelihood of an electrical fire will greatly increase. Hiring a professional to handle the job will drastically decrease, if not completely eliminate, the chances of disaster striking.
It is possible that your AC unit is not turning on because the thermostat is not set low enough. The ranges for each thermostat differs, so try setting the temperature two or three degrees lower than what you would like your house temperature to be and see if that kick starts your AC. If that does not work, it is possible that your thermostat may have a low battery.
Check to see if a low battery signal is showing and replace the battery accordingly. Sometimes, replacing the battery may still help even if the low battery alert is not showing. Otherwise, you may be facing a broken thermostat, which can only be fixed by your local AC experts.
You can also check to see if your thermostat is not working due to a malfunction. Try removing the cover of the thermostat first. This can be done by gently pulling off the cover by hand. Check to see if any wires are loose or out of place. If you detect that something has gone wrong with the system, it might be time to call in the professionals.
