Why is my system making a banging noise when thermostat is set to heat?
One of the main causes of a banging noise when your furnace is set to heat is because of a gas build up. Some people call this a “puffback”. This happens when your furnace isn’t igniting at the correct time. Gas is allowed to build up inside your furnace and is causing a mini explosion. There are several reasons for what is causing this to happen.
• Clogged burner
• Bad igniter
• Cracked heat exchanger
• Clogged exhaust
• Bad gas valve
The best way to prevent this from happening is to perform consistent maintenance on your system. Therefore, it is important to have a tune-up before every winter season! If you notice that this is happening to your system currently, we recommend that you call Falcon Air as soon as possible. This can lead to safety issues within the home if not handled quickly.

Another cause of an indoor unit making a banging noise is that one of the motors is going bad and needs to be replaced. We recommend that you get this replaced as soon as possible, as it may cause the unit to have other issues in the future. The best way to prevent this is by having a consistent maintenance plan to ensure the longevity of the unit and save you money over the long run.
There are multiple reasons on why the outdoor unit may be making a banging noise. It may be something as simple as the fan needs to be tightened or it may require a new fan motor.
