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

Things can get warm fast when your air conditioner won't turn on in Jacksonville. Thankfully, Air Engineers Service Experts is here to help you remain cool, even when your AC isn't starting properly. Here are eight possible reasons why your air conditioner won't turn on and how to fix them.

1) Check the Thermostat

The easy explanation for your AC not turning on is a thermostat issue. Double check your thermostat is on, set to "cool," and that the temperature is set to a few degrees lower than the normal ambient temperature of your home. You will also sometimes need to replace the batteries. If that doesn't take care of the issue, the temperature sensor in the thermostat could be inaccurate. A thermostat that can't read the set temperature could keep your air conditioner from turning on. Once you've verified that the thermostat is malfunctioning, it's time to replace it. If you can't decide on a thermostat that's right for your residence, speak 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 often depending on the number of pets and people living in your home, in addition to the local air pollution levels surrounding 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 think of the last time you changed it, it's time to get 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 check 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 fixing this issue, you could have a serious problem and should call the Experts at Air Engineers Service Experts to prevent 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 could have been flipped unintentionally. These switches are often located near your furnace, in a closet, crawl space or attic. Once you find the shutoff switch, make sure it's in the "OFF" position. If so, you’ll need to turn it back on. It's always a helpful idea to label this switch to prevent anyone from mistakenly turning it off.

5) Check the Outdoor Shutoff Switch

If you or someone else has recently serviced 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, simply flip it to allow your air conditioner to turn on.

6) Locate the AC's Reset Button

When your air conditioner won't turn on, it may simply need to be reset. Not all ACs have a reset button, so first find out if your unit does. If you can find the reset button, push it before attempting 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

Check 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 trying to start the unit or you risk damaging the AC. Though there are various reasons you could see ice on your air conditioner, it's always preferable to call Air Engineers Service Experts for a consultation to stop further damage from occurring.

8) Ensure the Condensate Drain Isn't Clogged

If you don't see 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, clear the drain line trying suction from a wet/dry vac. Check that you've resolved the blockage by pouring a small amount of clear water and watching it flow out. For severe clogs, it could be best to call the Experts.
