Whistling noise from the central air heating system with gas furnace?

Question

I have a new central air heating system with a new gas furnace. The whole house has one heating system but two zones. Whenever the upstairs call for the heating, the system starts to whistling. The noise is so strong that you can hear it anywhere in the house. Besides, I feel that the hot air blown out from the vents is very strong. It can shut a door if the door is open with about half foot opening.

Is this whistling noise normal? What is the solution to fix it?

Many thanks.

Answer 1

sounds like your getting to much Volume upstairs. there should be a damper somewhere around the furnace on the duct work. Its just a small lever that will close a flap in the duct. this will reduce the amount of air being forced up there and should take care of the Nosies you are hearing. If the nosies don't subside then there could be a small gap in the duct or vents somewhere. follow the nosies to its loudest area and see if you can pinpoint it that way.

Answer 2

It can be caused by a restricted filter or a leak in the ductwork that wasn't sealed properly. More than likely, it's a normal, mechanical noise. Some noise should be expected.

Answer 3

its the wind...air passing a hole or something in duct work....Listen at each vent and open an close different ones until you find the one dooin it..I had the same deal,,i had 1 vent 3/4 closed because the room was too hot..just opening it a little stopped it

Answer 5

We had that, and it was a clogged hepa filter. The noise went away when the filter was removed, and did not come back when the new filter was put in.
