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 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.
1) Check the Thermostat
The easiest explanation for your AC not turning on is a thermostat malfunction. 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 might also need to replace the batteries. If that doesn’t take care of 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 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, consult with an Expert to help determine the best choice.
2) Check the Air Filter
Your air filter should be exchanged 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 surrounding your residence. A dirty air filter can impact airflow, causing your air conditioner to freeze and not turn on.
If your air filter appears dirty or you can’t recall 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 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 may 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.
4) Check the Indoor Shutoff Switch
Often mistaken for a light switch, if your AC won’t turn on, the indoor shutoff switch might have been flipped unintentionally. These switches are usually found near your furnace, in a closet, crawl space or attic. Once you find 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 stop anyone from mistakenly shifting it off.
5) Check the Outdoor Shutoff Switch
If you or someone else has recently worked on 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) Find the AC’s Reset Button
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, press it before going to turn your AC on again. If you can’t locate the reset button, manually reset your air conditioner by turning 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 might see ice on your air conditioner, it’s always best to call Service Experts Heating, Air Conditioning & Plumbing for a consultation to stop further damage from occurring.
8) Ensure the Condensate Drain Isn’t Clogged
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, clean the drain line with suction from a wet/dry vac. Check that you’ve removed the blockage by pouring a small amount of clear water and watching it flow out. For particularly tough clogs, it could be best to call the Experts.
