Eight Reasons Why Your AC Won't Turn On-And What to Do

Things can get uncomfortable fast when your air conditioner won't turn on in Haltom City. Thankfully, Stark Services is here to help you keep your cool, even when your AC isn't working properly. Here are eight potential reasons why your air conditioner won't turn on and how to fix them.

1) Check the Thermostat

The easiest explanation for your AC not turning on is a thermostat problem. Double check your thermostat is on, set to "cool," and that the temperature is set to a few degrees colder than the normal ambient temperature of your home. You might also need to replace the batteries. If that doesn't fix the issue, the temperature sensor in the thermostat may be inaccurate. A thermostat that can't read the correct temperature could stop your air conditioner from turning on. Once you've verified that the thermostat is broken, it's time to replace it. If you can't decide on a thermostat that's right for your residence, consult with an Expert to help determine the best choice.

2) Check the Air Filter

Your air filter should be cleaned or replaced every 30-60 days at minimum. You should change them more regularly depending on the number of pets and people living in your home, in addition to the local air pollution levels near your residence. A dirty air filter can restrict airflow, causing your air conditioner to freeze and not turn on.

If your air filter appears dirty or you can't remember the last time you changed it, it's time to install a new one. If your AC was frozen, wait for it to thaw after changing the filter before turning it back on.

3) Check the Circuit Breaker

Open the electrical panel inside your home and try to see if the circuit breaker connected to your air conditioner is tripped. You can identify if the breaker is tripped if the switch has flipped to the "OFF" position. To resolve this issue, simply flip the breaker so that it's in the "ON" position.

If your AC continues to trip the breaker after correcting this issue, you might have a serious problem and should contact the Experts at Stark Services to keep it from damaging your home or air conditioner.

4) Check the Indoor Shutoff Switch

Often mistaken for a light switch, if your AC won't turn on, the indoor shutoff switch might have been flipped accidentally. These switches are usually located near your furnace, in a closet, crawl space or attic. Once you find the shutoff switch, confirm it's in the "OFF" position. If so, simply turn it back on. It's always a smart idea to label this switch to keep anyone from mistakenly turning it off.

5) Check the Outdoor Shutoff Switch

If you or someone else has recently worked on your air conditioner, they may have turned off the external shutoff switch as a safety precaution. First, locate the external shutoff switch, which should be near your AC unit. If the switch is in the "OFF" position, just flip it to allow your air conditioner to turn on.

6) Identify the AC's Reset Button

When your air conditioner won't turn on, it might simply need to be reset. Not all ACs have a reset button, so first verify if your unit does. If you can find the reset button, move it before trying to turn your AC on again. If you can't find the reset button, manually reset your air conditioner by turning your thermostat off for five to 10 minutes before turning it back on again.

7) Inspect the AC for Ice Buildup

Inspect the air conditioner for any icy buildup either on or inside the unit. If you discover ice on your machine, you need to wait for it to thaw before going to start the unit or you risk damaging the AC. Though there are various reasons you might see ice on your air conditioner, it's always preferable to call Stark Services for a consultation to prevent further damage from occurring.

8) Ensure the Condensate Drain Isn't Clogged

If you don't find ice on the air conditioner, the condensate drain could be backed up. When clogged, your AC won't turn on as a safety precaution. To resolve the issue, clean the drain line with suction from a wet/dry vac. Check that you've fixed the blockage by pouring a small amount of clear water and watching it flow out. For particularly tough clogs, it may be best to call the Experts.
