Loose Screws

When your system is running it vibrates the entire time. This is normal and just how the system runs. With all this vibration it can shake some of the screws loose in the system that hold panels and items together. One of the things to look for when your system is getting louder is these loose screws. Turn off the system before going into it with your tools. Check to see that all screws are tight and fitting properly. When they are tightened the noise should reduce if this was the main issue in the unit.
