Just moved into a new townhouse
A Tempstar IIS 90 was installed along with a Goodman Heat Pump GSH 1303
The noise from the cold air return as well as when the furnace is operating sounds like I am a passenger on 747 with the engines running.
Is the duct work sized differently if you have furnace with a heat pump versus no heat pump.
When the furnace is operating the air that is pushed up into the house makes excess noise.
Should a furnace with heat pump be any noisier than a furnace without one.
