Hi guys. What a great site!
I just ran across this forum while researching a question that just came up after having my furnace checked for the year.
This spring we bought a 7 y.o. 2600 sq. ft. ranch with a full basement in se lower Illinois. It has a Heil 125k btu, DC90 furnace with AC. Im am not sure what brand the AC is.
We had a local company come out to do the service. The company came very well recomended by a couple neighbors.
I was there during the service and the technician gave me the following recomendations and I was hoping for someone to let me know if the suggestions are good ones:
1) The static pressure is supposed to be .5, it checks .59 The serviceman recomended adding additional return air. Each room, except the kitchen and bathrooms already has a return air vent high on the wall. Each of the grills measure app. 8 by 16 inches. We have (6) total returns in the house with 26 registers that the heat comes out from.
He said he wouldnt recomend adding return air to the bathroom or kitchen because of odors. He said there are a couple options, A) enlarge the exisiting return openings in the wall and use the next size larger grill. B) add a return grill directly below one of the existing returns, about a foot off the floor. He said if I didnt add the additional return air it would shorten the life of my furnace. Is this true? What option would you suggest?
2) Our house is L shaped and one room (daughters bedroom) farthest from the furnace is about 3 degrees colder than the other rooms. He said zone heating was about my only option. Is there another option?
The strange thing is that during the summer, when the ac was running, the room was the same temp as the rest of the house. My daughter didnt start to complain about the temperature untill the cold weather arrived.
