I had my old gas furnance replaced today, which was about 21 years old, and due for replacement. It was replaced with a York Affinity single stage gas furnace, model #PV9B12N080UP11, 92% efficiency.
This unit is LOUD, much more so compared to my old 80% unit. When the unit turns on, I hear a loud "wooshing" through my vents. The advertising for this unit says its supposed to be "quiet".
Can anyone offer any thoughts as to why this may be so loud?
Many thanks in advance...
