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 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 malfunction. Double check 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 take care of the issue, the temperature sensor in the thermostat may be inaccurate. A thermostat that can’t read the desired temperature could stop your air conditioner from turning on. Once you’ve verified 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 exchanged every 30-60 days at minimum. You should change them more regularly depending on the number of pets and people living in your home, and the local air pollution levels close to your residence. A dirty air filter can affect airflow, causing your air conditioner to freeze and not turn on.
If your air filter appears dirty or you can’t remember the last time you changed it, it’s time to replace it with 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 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 resolving this issue, you could have a serious problem and should call 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 may have been flipped on accident. These switches are usually placed near your furnace, in a closet, crawl space or attic. Once you locate the shutoff switch, confirm it’s in the “OFF” position. If so, simply turn it back on. It’s always a smart idea to label this switch to keep anyone from mistakenly turning 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, find 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 may 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, press 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.
Look over 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 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 preferable 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 could be backed up. When clogged, your AC won’t turn on as a safety precaution. To resolve the issue, unclog the drain line trying 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 might be best to call the Experts.
