Reasons Your AC Is Not Turning On & How To Fix Them

Arizona is famous for its hot climate, so it’s important to keep home fresh with a high-quality AC. Unfortunately, air conditioners can fail over time, and the first sign is usually not turning on. 

This issue can be caused by several things, from worn-out parts to electrical problems.

The best you can do is to call a Gilbert HVAC service to check your system. They’ll be able to diagnose the problem and fix it before it gets too cold or hot inside.

Another thing you can do is to follow these steps while waiting for the technician. This way, you can keep the issue under control and not worsen it. 

Reasons Your AC Is Not Turning On & How To Fix Them in Maricopa, AZ

1. Check Your Thermostat Settings

It may sound obvious, but you should check your thermostat first. See if it’s set to “cool” and if the desired temperature is lower than the room temperature. You can also see if the fan is on “auto” mode or “on” mode. The fan will only work properly if the air conditioner is cooling air.

With the “on” mode, the fan can run continuously without issues, even if the air conditioner is not cooling air yet.

Is your thermostat blank? Check the batteries, it may need new ones, or something might have damaged the circuit breaker.

If the circuit breaker is the problem, check the next step. 

2. Check The Circuit Breaker Panel

HVAC systems need much power to work properly, so they can cause problems to the electrical circuits. A sudden power surge can make the circuit breaker fail and stop electricity from running through the circuit. 

Your Chandler HVAC service will probably ask you to check the breaker before doing anything else. Remember, your AC won’t be able to turn on if there’s a problem with the circuit breaker. 

The circuit breaker will switch from the “on” position to “off” if it has tripped. By resetting the breakers, you should solve this issue. All you have to do is to flip them back to the “on” mode.

See If Your HVAC System’s Power Switches Are On

Most central air conditioners have two power switches. One works with the indoor unit, and the other one with the outdoor unit. Both switches must be in the “on” mode for your air conditioner system to work. 

You should find the switch for the indoor unit near the system’s furnace handler. Check it out to ensure it is set as “on.” 

The switch for the outdoor unit is usually in a metal box near the exterior of your house.

Check The Air Filter

Air filters can be the source of problems too. See if your AC air filter is dirty and needs a replacement.

Dirty air filters can restrict airflow from running smoothly through your AC, making it work harder. According to a Ahwatukee AC Contractor: “The harder the work, the higher the chances of overheating.” 

Overheating can make your HVAC stop working, hence the importance of replacing the air filter at least once every three months.

Aren’t you sure when to replace the air filter? If it looks visible dirty, replace it. Keep several filters at home so you can replace them when needed.

Make Sure There’s No Debris Crowding Around The Outdoor Unit

Dirt, loose leaves, and debris can block outdoor units, stopping normal airflow and causing your AC to overheat and stop working. Check for plants and debris around the outdoor unit and remove them. 

Also, ensure at least two feet of clearance around the unit. And since most outdoor AC units release most heat from the top, make sure there’s a lot of overhead room to breathe properly.

Try Resetting Your HVAC Unit

Most electric units act strangely after a power surge trips the circuit breaker, and HVAC systems are no exception. Fortunately, you may only need a hard reset to make it work again. 

Check your system’s owner’s manual for more instructions on how to correctly reset your unit and avoid more issues.
