Seeking quietest furnace
I'm getting bids on a 4 ton furnace that will be in a utility closet in a finished basement. I'm looking for the quietest possible unit.
We have bids from two reputable installers, one for a Rheem modulating, the other for a Carrier Infinity 96.
I'm in Portland, Oregon with fairly mild winters. It seems there is a chance that the Rheem modulating might generally keep the system at a lower fan speed than the Carrier, which would seem to keep things quiet.
On the other hand, the published sound rating is lower for the Carrier. (for what this is worth)
I've heard proponents of each system claiming that it is quiet, but not yet from anyone who has experience with both systems (and possibly others). I'd appreciate any advice.
