Things can get uncomfortable fast when your air conditioner won't turn on in La Porte. Thankfully, Finch Air Conditioning & Heating is here to help you keep your cool, even when your AC isn't functioning properly. Here are eight typical reasons why your air conditioner won't turn on and how to fix them.
1) Check the Thermostat
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 cooler 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 desired temperature could stop your air conditioner from turning on. Once you've verified 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 changed 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 surrounding your residence. A dirty air filter can restrict airflow, causing your air conditioner to freeze and not turn on.
If your air filter appears 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 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 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 might have a serious problem and should call the Experts at Finch Air Conditioning & Heating 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 could have been flipped unintentionally. These switches are often located near your furnace, in a closet, crawl space or attic. Once you locate the shutoff switch, check to see if it's in the "OFF" position. If so, you’ll need to turn it back on. It's always a good idea to label this switch to keep anyone from mistakenly shifting it off.
5) Check the Outdoor Shutoff Switch
If you or someone else has recently repaired or maintained 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, 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 could 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 shutting 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 ice buildup either on or inside the unit. If you come across ice on your machine, you need to wait for it to melt before trying to start the unit or you risk damaging the AC. Though there are various reasons you could see ice on your air conditioner, it's always smartest to call Finch Air Conditioning & Heating 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 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. Test that you've removed the blockage by pouring a small amount of clear water and watching it flow out. For severe clogs, it may be best to call the Experts.
