Our new Carrier two speed furnance, for this new ranch home, is located in the basement, under the hallway near the three bed rooms as per the architect's drawings. The cold air return for the master bed room is the closest to the furnance. There are 6 cold air returns vents in this home, 3 doubles and 3 singles. The doubles are approximately 6" wide x 30" long, the singles are approximately half that size.The cold air return vents are located high up on the walls. When the blower is on you can hear the rush of cold air in the master bedroom and one of the other bedrooms. It is a nuisance when one is trying to fall asleep.

I have contacted the heating and cooling contractor and he has installed some dampening material in the cold air return of the master bedroom. The noise level has been reduced by about 50%, but at times it still can keep one awake.

I want to make the following suggestions to the heating and cooling contractor.

1. Install a double vent, in the wall, in the hallway opposite the one in the master bedroom.

2. There is room to install double vent in one of the other bedrooms. No air rush noise in this bedroom.

3. In the other bedroom, where there is air rush noise, there is no room for a double vent, but I believe dampening material in the cold air return would be enough.

4. In the basement, in the cold air return duct, near the blower,install a cold air return vent to "bleed" off some of the air.

5. The most drastic action would be to block off the cold air return to the master bedroom and one of the other bed rooms, but I do not know what this would do to the air balance, but at least we could get some sleep.

I have programmed the thermostat to go to a lower temperature when we go to bed and hope to fall asleep before the blower comes on.

We live in Up State N.Y. and the heating season is longer than the so called cooling season.
I am open to any other suggestions. That's it.

The hallway closet is further away from the furnance than any of the bedrooms. The closet has ceramic tile in it. Any other suggestions. Thank You.

Thank you. After this cold snap passes, I will contact the heating and cooling contractor. He is up to his eyeballs in trying to get to people that need heat. I will pass this information on to him.

I have a similar problem, bought an old house that had no cold air return on the 2nd floor. Had a large one added and it has a loud wind noise even though it is a 12 in pipe. I think it is because it ties in close to where the main trunk is at the furnace, so all returns are racing to get in right at the filter point. Am considering having it ducted into the other side of the furnace and adding a second filter. This stuff is hard to figure out when you are not an HVAC guy. But to be honest I am amazed how many differences of opinions there are from professional companies in these areas. Where is the science. Anyway, suggestion or info on how your issue was solved would be appreciated.
