Lennox, Trane, American Standard, Carrier, York. Don't get the least
expensive madel from anyone. Go at least middle price for good
quality. Most of these manufacturers have at least 5 lines of gas
furnaces.

Also make sure your contractor does a load calculation to determine the
proper size. A load calculation is NOT just the square feet of floor
area. They have to measure sqare feet of walls, windows, doors,
ceilings, floors. They have to know r-factors and what kind of windows
and which way they face. IF they don't do that, get another
contractor.
