Why Your AC Won’t Turn On
As the weather heats up, no one wants an unreliable AC unit. There are a number of reasons why your ac won’t turn on and we're breaking them down.
As the Arizona weather starts to heat up, having a working AC unit is essential for your health and keeping cool. If your AC won’t turn on, there are a number of reasons why this could be happening. It isn’t uncommon for an air conditioning unit to stop working; in fact, there are several common reasons for it. We’re breaking down these common reasons your AC won’t turn on and what steps you can take to troubleshoot them.
A Tripped Breaker
Circuit breakers are designed to protect your home from electrical overloads. Whenever there is too much electricity, they will shut off. This is a good thing when it comes to protecting your home from fires but could be a reason why your AC won’t turn on.
Thankfully, checking and resetting your breakers is pretty easy. Start by opening the door to your breaker panel. Inspect each of the toggles to see if any are not completely in the “ON” position. If you find a toggle that is in the “OFF” position or halfway between the two, then you’ve found your tripped breaker. To reset it, completely turn the breaker to the “OFF” position and then back to the “ON” position. If the breaker trips again, we recommend contacting an electrician as there may be a problem with the circuit.
Clogged Air Filters
We all know that we should replace our air filters every 90 days, but that doesn’t mean that we always stay on top of it. While this will affect your home’s air quality, it could also play a role in why your AC won’t turn on. If it has been a while since your air filter was last replaced, it could begin to collect too much dust and debris. When this happens, it blocks the cool air from leaving your air conditioner. The trapped cool air can then cause ice to form on the AC unit’s coils, which leads to the AC system freezing up and not turning on.
It’s always important to stay on top of replacing your air filters regularly. It can be helpful to set reminders after each replacement so that you know when the next filter needs to be installed. Remembering to change the filters is usually the hardest part. To swap out your air filters, you’ll want to make sure that the air is turned off first. Next, you’ll open your ceiling vent and remove the old filter. When you install your new AC filter, make sure that it is the same size as the old one and that the arrows on the side point towards the ceiling.
The Thermostat Needs to be Replaced
Your thermostat is key to running your AC system. As the control center, if your thermostat is broken, your AC won’t turn on because there is no signal going out to the system. Any number of reasons could prevent your thermostat from working properly. From something as simple as expired batteries to more complicated issues like faulty wiring. Whatever the reason, if you can’t access control to your thermostat, it could lead to problems with your air conditioning unit. If you believe your thermostat is the cause of your AC problems, running a thermostat test can help you determine if it is the reason your AC won’t turn on.
