I am looking to replace my old oil furnace in my home this summer with a new natural gas system now that we have access to natural gas in the neighborhood. I have gone around to friends houses that have relatively newer gas furnaces, and inspected their equipment and the installations to decide on what and who I want to install my equipment. One thing I have noticed is that the draft blowers on the new gas furnaces sound like small vacuum cleaners running! My parents installed a Bryant induced draft furnace back in the 80's, and the draft blower in it made no more noise than a desk fan running. You could hear a dull rush of air, but easily dampened by closing a closet door.
My equipment is going in a closet that is beside a basement home theater room. The oil furnace in there now makes a bit of noise that can be a little objectionable, but I was hoping a new gas furnace would be quieter, but every one I have seen appears to be noisier than that 20-year old Rheem with a Beckett AFB. The units I have seen were from Heil, Lennox, Trane, and Carrier... I'm leaning towards a Rheem system, but don't know of any installed yet to observe. I have heard though that they were one of the noisiest brands, so that may take them off the list!
Looks like I may need to do some construction mods to dampen the noise after the new system is installed, unless any of you all know of a particularly quiet model available that has good noise performance
