Hi, I'm new to the forum and have been reading and getting a ton of great info.
I currently have a 100,000 BTU furnace but think it is too big. I did a preliminary heat loss calculation and came up with needing about a 70,000 BTU furnace. I'm looking at getting a new High efficiency, 2 stage, variable speed furnace and I have found someone who can get me a screamin' deal on either a 100,000 or 125,000 BTU furnace. He was telling me that with the variable speed it doesnt matter that much if you get a bigger furnace than you need as it will just run on the lower speed most of the time and kind of act like a smaller furnace and acutally on those really cold days, having the extra BTU's might be helpful.
Does this sound right to you or is it a bunch or baloney?
