I just had the noisy ventor motor changed in my 3 month old Trane XR90. The new one is not as noisy but it still seems louder than what I would expect. How much sound should these motors emit?
The single stage Tranes aren't particularly noisy. If you aren't used to inducers, hard to say- one we might call quiet may seem noisy to you. Usually they aren't that audible once the burners & main blower are going too.
