What to Check When Your Air Conditioner Doesn’t Power On

It can be frustrating when your air conditioner fails to turn on, especially during particularly scorching summer days. Unfortunately, there are several different reasons you may not be able to turn your AC on. This article will help you troubleshoot what the possible cause is and when calling a professional is essential.

Check the AC Power Source

If your air conditioner doesn’t turn on, one of the first things to check is if it still has power. You may have tripped the circuit breaker. If this is the case, the switch to that circuit needs resetting. Find your home’s electrical panel and examine the circuit breaker inside. If it looks like that circuit has been tripped, switch it back to the on position and try turning your AC on again. However, if the circuit breaker trips again, it can signal a more serious issue that requires a professional to diagnose and repair.

Examine the AC Thermostat Settings

Check to ensure that the thermostat settings are correct. While your AC might technically be on, the wrong settings can make it appear off. Ensure your air conditioner is in cooling mode. Additionally, the temperature needs to be set on the thermostat lower than the current temperature of your space. Ensure your fan setting is high enough, otherwise you may not notice if cool air is blowing out the vents.

Air Filter Inspection and Replacement

Inspect your air filters and ensure they aren’t clogged. If they are, replace or clean them depending on the type of system and air filters you have. Clogged air filters will block your system’s airflow, making it feel like your AC isn’t on. Additionally, if your system overheats due to the blocked airflow, this can cause your system to shut down as a safety precaution.

External Unit Inspection

Check your air conditioner’s external condenser unit. Make sure there isn’t any debris that can be obstructing the unit’s airflow. Clear it of grass, leaves, and dirt. Additionally, listen for strange noises from the external unit when you attempt to turn your AC on. If it is making weird noises, it can signal mechanical issues.

Condensate Drain Line Inspection

The condensate drain line removes excess moisture in your AC due to the cooling process. If this drain line becomes clogged, it can cause water to back up inside your system. Many ACs have safety measures that automatically shut the system down if this happens, preventing water damage.

As you can see, there are various reasons that an air conditioner won’t turn on. While homeowners can handle issues like air filter replacement, many problems require professional help. If you live in Topeka, KS and need your AC repaired, contact our team at Kaw Valley Heating and Cooling today!
