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 the U.S.. Thankfully, Service Experts Heating, Air Conditioning & Plumbing 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 simplest 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 lower than the normal ambient temperature of your home. You may also need to replace the batteries. If that doesn’t solve the issue, the temperature sensor in the thermostat may be inaccurate. A thermostat that can’t read the correct 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, 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 frequently depending on the number of pets and people living in your home, plus 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 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 moved 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 could have a serious problem and should get in touch with the Experts at Service Experts Heating, Air Conditioning & Plumbing to stop 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 on accident. These switches are usually placed near your furnace, in a closet, crawl space or attic. Once you reach the shutoff switch, confirm it’s in the “OFF” position. If so, just turn it back on. It’s always a helpful idea to label this switch to prevent anyone from mistakenly shifting it off.
5) Check the Outdoor Shutoff Switch
If you or someone else has recently repaired or maintained your air conditioner, they may have turned off the external shutoff switch as a safety precaution. First, find 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) 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, move it before trying to turn your AC on again. If you can’t locate the reset button, manually reset your air conditioner by switching your thermostat off for five to 10 minutes before turning it back on again.
7) Inspect the AC for Ice Buildup
Look over the air conditioner for any icy buildup either on or inside the unit. If you find 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 may see ice on your air conditioner, it’s always smartest to call Service Experts Heating, Air Conditioning & Plumbing for a consultation to prevent 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 might 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. Verify that you’ve removed the blockage by pouring a small amount of clear water and watching it flow out. For serious clogs, it may be best to call the Experts.
