I have a 22 year old furnace that I'm thinking of having replaced. It's a Bryant Plus 90 350MAV048100. My home is two stories, 4 bedrooms with a large family room attached to the main dwelling. I would appreciate a ballpark estimate (a couple of suggestions) for the furnace replacement. If I like your estimates, I'll arrange to have you come see the current installation. The AC is newer and will not need replaced. Thanks.
