Things can get uncomfortable fast when your air conditioner won't turn on in Edmonton. Thankfully, McKinley Heating Service Experts is here to help you remain 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.
1) Check the Thermostat
The easiest explanation for your AC not turning on is a thermostat issue. 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 might also need to replace the batteries. If that doesn't take care of the issue, the temperature sensor in the thermostat might be inaccurate. A thermostat that can't read the desired temperature could keep 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, ask 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, in addition to 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 seems 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.
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 correcting this issue, you may have a serious problem and should call the Experts at McKinley Heating Service Experts to prevent 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, check to see if it's in the "OFF" position. If so, simply turn it back on. It's always a good 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 serviced your air conditioner, they could 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, you’ll need to 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 may 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 going to turn your AC on again. If you can't find 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
Check 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 smartest to call McKinley Heating Service Experts for a consultation to stop further damage from occurring.
8) Ensure the Condensate Drain Isn't Clogged
If you don't see ice on the air conditioner, the condensate drain may be backed up. When clogged, your AC won't turn on as a safety precaution. To resolve the issue, unclog the drain line with suction from a wet/dry vac. Verify that you've removed the blockage by pouring a small amount of clear water and watching it flow out. For severe clogs, it could be best to call the Experts.
