How to Troubleshoot Your Air Conditioning Unit

Are you having a problem with your air conditioner? Whether the fan is running a little slow or it’s not turning on at all, you can do a bit of air conditioner troubleshooting yourself. Here’s how to figure out what might have stopped your air conditioner from working its best.   

Is Your Air Conditioner Not Turning On? 

If your air conditioner is not working because it just won’t turn on there are a few things you can check before you call the experts. The most common cause is a problem with the thermostat’s setting. Make sure that your thermostat is set to a temperature below your home’s current temperature to get the air conditioner to turn on. 

If you have a smart thermostat then things might be a bit more complicated. Some smart thermostats will override direct instructions to turn on the air conditioner if something is wrong with them or their schedule. If so, check the smart thermostat manual for additional troubleshooting tips. 

Now check if things on the same breaker as your air conditioner work. If not, the air conditioner may have tripped the breaker. All you have to do is head to your electrical panel and flip the breaker.   

It’s also worth mentioning that if you have a window-unit air conditioner that connects to the power on its own, be sure it is plugged in. That might sound silly, but it’s a wise thing to check before you get a professional to drive down for you. 

If you still can’t figure out why your air conditioner isn’t turning on, you may need to call up your HVAC technician, as the other causes of this problem are internal problems in the unit.

Is Your Air Conditioner Fan Not Working?  

Does it seem like the cold air from your air conditioner doesn’t quite make it as far as it used to? Or maybe the fan doesn’t turn on at all? 

You should first check the potential cause that is the easiest to solve: a dirty filter. A filter that is full of debris, pet hair and dust can significantly interfere with the air pressure in the air conditioner and make it seem like the fan isn’t working. All you need to do is replace the filter. 

If you can see the fan in your air conditioner and it is clearly not turning, then it might be an issue with the capacitator. The capacitator tells the fan to move when the air conditioner first comes on. If there is an issue with capacitor, it will be unable to send the right signal to the fan and will need to be replaced. An HVAC professional will be able to confirm this for you. 

Other problems with the air conditioner fan are best left to the professionals. If you can’t determine what’s going on, contact Anchor ClimateCare first!
