    Answer: 
    Thank you for your question on the model 671 exhaust fan. There should not be air blowing back down into the room. It sounds like you may have a stuck back draft damper or an obstruction in the duct work. Please contact the Technical Service Department at 800-637-1453 for further assistance.

    Unfortunately I live in a condo with no access to the attic and I also don't have the ability to change my 3'' exhaust duct. I noticed that most of your light/fan combos have a 4'' duct. Is there anything I can do? Do you have any products that have both the light/fan combo along with a 3'' duct? Or might you offer a lighting kit solution for the unit I already have? Any help would be appreciated!

    Thank you for your question on the model 663-C/688-C exhaust fan. The only parts that can be used in the 663-C/688-C housing would be the original replacement parts. There is no light kit for it. We also do not have a fan/light combination that will use three inch duct work. They all use at least four inch.

    Trying to uprgrade 688-h/663-h

     on 688
    Looking at upgrade kits for 688-h/663-h for home built in 1989 that is rated at 50cfm and 2 sones. Was looking at broan 690 which states sound reduction up to 50% but it is listed at 3 sones? Is that correct? My current fan sure is noisy, so would this "upgrade" be noisier?

    Answers

    Answer: 
    Thank you for your question on the Broan model 688-H/663-H. A number of years ago, HVI (Home Ventilating Institute) changed the way they rated all fans for sone levels. This fan may have been originally rated at 2.0 sones, but when HVI changed their procedures, the sone rating changed to 4.0 sones. Our fans did not change in any way, only their procedures for testing the fans for sones changed.
    The 688-H would be compatible with the 690 upgrade kit. The 688 is now rated at 50 cfm's with 4.0 sones. The upgrade kit will give you 60 cfm's with 3.0 sones. If you have further questions, please contact Technical Support at 800-637-1453.
