Air Conditioner Unit Not Blowing Air? Three Troubleshooting Tips To Try
Air conditioning is definitely a luxury during the hot, long days of summer. Window units or Central Air goes a long way towards lowering the temperature in a building so it's nice and comfortable. It is important that you keep up to date on your AC maintenance annually so it continues to run properly. The last thing you want is to be stuck in the middle of a heat wave without any way to escape the treacherous temperatures. If your AC unit does break down, you can learn how to troubleshoot it so you don't have to wait for the AC contractor to show up and save you. One of the biggest issues people have is an air conditioning unit that doesn't blow any air. This troubleshooting guide shows you the steps to take to fix it.
Filter
Check the filter. All AC units have a filter in them. The filter collects dust and grime on it over time. You need to remove the filter at least twice a year and clean it off. Simply take a damp rag and run it along each side of the filter until it's clean. If you have a replaceable filter, then just replace it with a new one. This should improve the airflow. If not, move to the next step.
Blower Belt
The issue may be with the blower belt. Before you can check this, you need to make sure the AC is completely powered off. Consult your manual to locate the blower belt. It's usually behind a cabinet on the unit. Inspect the belt for any damage, like cracks. It may even be snapped off completely. Find the model number listed on the belt so you can replace it. A new belt can be found at any home improvement store. Just slide the new belt onto the spot the old one was in. Restart the unit and see if it is blowing air correctly. Otherwise, move to the next step.
Circuit Breaker
If the unit isn't working the way it should, it may have tripped a circuit. Locate your breaker box and find the spot marked "AC Unit." If the breaker was tripped, reset it. You may need to replace the entire fuse. Always make sure the unit is connected to its own power and not sharing power with any other appliances.
Considerations
After completing all these steps, you should have a unit that is working again. If it is not, you may need to contact a local HVAC contractor and have them inspect the unit. They are trained to diagnose issues with AC units.
