We received a question from Ancha:

"HI, I moved to a new house, my Aprilaire 760 humidifier works, but makes sound (I mean, when it works, the sound is really uncomfortable upstairs). Is it supposed to work like this?  I mean, I will buy a new unit and install, but are humidifiers supposed to make so much noise? Or can I fix this noise in the existing unit?  Thank you for reply"

Aprilaire response
The Model 760 is a fan-powered humidifier, meaning that there is an on-board fan that draws air across the evaporator water panel to achieve maximum humidification.  Fans do create sound, however, the sound is generally not audible over the blower of your HVAC system.  It can be noticeable if you have a variable speed HVAC blower, and you are operating on low speed while humidifying.  Even then, however, it should not be an "uncomfortable" sound. 

That said, it sounds like the fan motor in the humidifier may need some attention.  Please contact your local Aprilaire dealer, who can diagnose the problem and offer you the best solution.

Thank you for your question and thanks for choosing Aprilaire!
