New Motor Much Louder
Hi. This is Kevin from Orlando, Florida. In 2009 I purchased a house built in 2004 that had a Beam Serenity Plus, model 2725. Since I have had two other houses with central vacs, I am familiar with the amount of noise produced when they are running (all units are/were in the garage). My current unit ran much quieter than the others, but recently the motor died and was replaced by a technician from my home warranty company. The new motor sounds like something is wrong - it is extremely loud and sounds like it needs lubricated. It is so loud that it can be heard in the farthest room from the garage. The tech says it's brand new, but I know that this unit is way too loud. Although it has the same suction power as the old motor, I'm just not convinced it is a normal noise. Any thoughts?
It may have been installed incorrectly. If the new motor is tightened down too much, it compresses the fan housing and the blades can rub against the outside. This creates a drastic increase in the level of sound coming from the motor.
