I live in N.W. Iowa in a single story ranch home with 1000 sq. feet, with a partial finished basement. We are looking into replacing our 23 year old single stage 74,000 btu furnace only. I have a quote from a local contractor for Trane and was wondering if this setup sounds correct for us. I will be replacing our Central Air some time down the road, but for not it still works so we are trying to save some money. We were quoted a model TVH2B080R9V with a Media Filter and a TCONT802
thermostat. Can you also advice what is the best way to determine if we have enough cold air return for this system.
We currently only have one cold air duct and a divider wall between the living room and dinning room. The register is on both sides of the 3.5 inch wall and is 8" x 31", this drops down through the floor into the cold air duct in front of the furnace and it measures 8" x 16" x 5 ft. He suggested adding a cold air return in the basement in the wall into the finished living area to aid in heating that room and also being able to run the fan only when we have the free standing wood stove in the room going to circulate the warm air through the whole house.
