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 keep your cool, even when your AC isn’t functioning properly. Here are eight possible reasons why your air conditioner won’t turn on and how to fix them.
The simplest explanation for your AC not turning on is a thermostat problem. Check to ensure 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 resolve the issue, the temperature sensor in the thermostat could be inaccurate. A thermostat that can’t read the correct temperature could stop your air conditioner from turning on. Once you’ve discovered 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, ask an Expert to help determine the best choice.
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 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 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.
Open the electrical panel inside your home and attempt 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 resolving this issue, you could have a serious problem and should get in touch with the Experts at Service Experts Heating, Air Conditioning & Plumbing to prevent 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 could have been flipped on accident. These switches are typically placed near your furnace, in a closet, crawl space or attic. Once you locate the shutoff switch, check to see if it’s in the “OFF” position. If so, you’ll need to turn it back on. It’s always a good idea to label this switch to prevent anyone from mistakenly shifting it off.
If you or someone else has recently worked on your air conditioner, they might 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.
When your air conditioner won’t turn on, it might simply need to be reset. Not all ACs have a reset button, so first determine if your unit does. If you can find the reset button, move it before going 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.
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 thaw before going 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 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 might be backed up. When clogged, your AC won’t turn on as a safety precaution. To resolve the issue, unclog the drain line using suction from a wet/dry vac. Verify that you’ve fixed the blockage by pouring a small amount of clear water and watching it flow out. For severe clogs, it may be best to call the Experts.
