There aren't many household systems more confusing than plumbing, which is why I stopped trying to fix mine on my own. I realized that taking things apart was increasingly more difficult, so I stopped guessing and started looking for a trained expert who could come out and help. When I found the right professional, it was amazing to see how much easier things were. They went through, evaluated my plumbing system, and made changes that changed my home from the inside-out. Check out this blog to find out more about how to avoid plumbing problems and when to hire a professional of your own.
Weak airflow through your ducts may make your home feel warm no matter what setting you have on your thermostat. This can be especially frustrating if the air is cool but insufficient to properly cool the room. The following troubleshooting guide can help you find the root of the issue so you can increase the air flow from your AC unit.
Check the filter
It's common knowledge that the filter should be changed every month or two during the cooling season, but this is still the first troubleshooting tip if you air flow is suffering. Even if you recently changed the filter, take a few minutes to make sure there is no debris or a fault in the filter that could be affecting the air that is pulled through your system.
Look for ice
If the air flow was fine a little while ago and then constantly dropped off, you may have a frozen evaporator coil. This is often the result of overworking the AC system, and this causes the system to freeze up. To check the coil, you will need to lift the housing off the main outdoor unit. First, turn off the AC and then remove the screws that hold the housing in place. Once the housing has been removed, check the coils inside for visible frost. If there's ice, allow it to thaw, and then run the AC at a higher setting so it's not overworking.
Listen for the blower
When ice isn't present, the next likely cause is that the blower fan isn't operating correctly. Turn the unit back on and listen to see whether the fan also starts running. If it doesn't, shut off the unit and check for debris inside that could be preventing the fan from moving—a cleaning and a lubrication may help. Also, check to make sure the fan belt is attached and not showing signs of wear, and replace it if need be. If neither of these jumpstart the fan, it may be time to replace the fan motor.
Schedule a duct inspection
Leaks in the ducts could be the culprit if the AC seems to be operating correctly yet the air flow is weak. In this case, a duct inspection can help turn up any leaks or blockages that could be the root cause. Once these are repaired, your AC should begin cooling properly again.
