With winter approaching I am trying to increase the heat flow in my 4 bedrooms on the second floor of our home. We used plug in heaters for our kids rooms, and even with the house set at 75 degrees, the upstairs would not heat. Our house was built in 1964 in Buffalo, NY. Two story Colonial style. Our furnace is 3 years old. Heil make, model number H9MPD125L2OB1. 125,000btu.
I mentioned our lack of heat upstairs to the company who installed the new furnace (and the old one back in '93, according to the service log on the ductwork) and they said those rooms would be cold because they are the farthest from the furnace.
So I have been doing some looking around, starting with the cold air intakes in the upstairs bedrooms. I actually went in with a camcorder to get a good look. The first thing i noticed was that there was no ductwork. The returns appear to be just holes cut in the wall, with air traveling through them. The main intake register downstair has a noticeable airflow. Upstairs, I can hardly feel a flow. I have adjusted dampeners in the basement and there is no difference. My question is, how should the ductwork look for the cold air returns, and should it really be going all over the place (through the walls, under the floor, up to the ceiling)?
Please let me know what to do.
