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 keep your 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.
The simple explanation for your AC not turning on is a thermostat problem. 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 will also sometimes need to replace the batteries. If that doesn’t fix the issue, the temperature sensor in the thermostat could be inaccurate. A thermostat that can’t read the correct temperature could prevent 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, consult 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 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 affect airflow, causing your air conditioner to freeze and not turn on.
If your air filter looks dirty or you can’t think of 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 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 fixing this issue, you might have a serious problem and should call the Experts at Service Experts Heating, Air Conditioning & Plumbing to stop 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 accidentally. These switches are often found near your furnace, in a closet, crawl space or attic. Once you locate the shutoff switch, make sure it’s in the “OFF” position. If so, simply turn it back on. It’s always a helpful idea to label this switch to stop anyone from mistakenly shifting it off.
If you or someone else has recently repaired or maintained your air conditioner, they could 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, you’ll need to 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 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 switching your thermostat off for five to 10 minutes before turning it back on again.
Look over the air conditioner for any icy buildup either on or inside the unit. If you come across ice on your machine, you need to wait for it to defrost before going 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 stop further damage from occurring.
If you don’t come across 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 using suction from a wet/dry vac. Test that you’ve resolved 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.
