Things can get stuffy 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 stay cool, even when your AC isn’t running properly. Here are eight potential reasons why your air conditioner won’t turn on and how to fix them.
The easiest explanation for your AC not turning on is a thermostat issue. Make sure 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 may also need to replace the batteries. If that doesn’t resolve the issue, the temperature sensor in the thermostat could be inaccurate. A thermostat that can’t read the desired temperature could stop your air conditioner from turning on. Once you’ve learned that the thermostat is faulty, 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.
Your air filter should be changed every 30-60 days at minimum. You should change them more frequently depending on the number of pets and people living in your home, and 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 looks 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.
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 shifted 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 might have a serious problem and should contact the Experts at Service Experts Heating, Air Conditioning & Plumbing to keep it from damaging your home or air conditioner.
Often mistaken for a light switch, if your AC won’t turn on, the indoor shutoff switch may have been flipped accidentally. These switches are often 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, simply turn it back on. It’s always a good idea to label this switch to prevent anyone from mistakenly switching it off.
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, identify 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.
When your air conditioner won’t turn on, it could 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, push it before attempting to turn your AC on again. If you can’t find the reset button, manually reset your air conditioner by shutting your thermostat off for five to 10 minutes before turning it back on again.
Inspect the air conditioner for any ice buildup either on or inside the unit. If you discover ice on your machine, you need to wait for it to melt 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 smartest to call Service Experts Heating, Air Conditioning & Plumbing for a consultation to stop further damage from occurring.
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, clear the drain line with suction from a wet/dry vac. Test that you’ve fixed 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.
