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 running properly. Here are eight possible reasons why your air conditioner won’t turn on and how to fix them.
The easy 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 might also need to replace the batteries. If that doesn’t solve the issue, the temperature sensor in the thermostat may be inaccurate. A thermostat that can’t read the set temperature could prevent your air conditioner from turning on. Once you’ve discovered that the thermostat is malfunctioning, 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 cleaned or replaced every 30-60 days at minimum. You should change them more often 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 affect 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 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 try 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 correcting this issue, you could 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 might have been flipped unintentionally. These switches are usually found 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, you’ll need to 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 serviced 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, just 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 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 reach the reset button, manually reset your air conditioner by turning your thermostat off for five to 10 minutes before turning it back on again.
Check 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 thaw before attempting 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 best to call Service Experts Heating, Air Conditioning & Plumbing for a consultation to keep 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, clean the drain line trying 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 serious clogs, it could be best to call the Experts.
