Regular duct maintenance is important. However, homeowners also play a crucial role. You can check your ductwork for issues, and you should do this regularly. Follow these instructions every time you check your ducts.
- Turn on the HVAC system.
- Make sure all external doors and windows are closed.
- Shut all interior doors.
- Crack open each interior door one by one.
If you notice the interior doors moving, your ductwork may have problems. This is when you should contact professional help.
