Replacing a gas furnace and adding AC to a forced air heating system
May 26, 2011 12:52 PM Subscribe
We have an oldish (~90 years or so) house with a gas furnace and forced air heating. We're thinking of replacing the furnace and adding an AC compressor for cooling. I'm looking for recommendations for specific furnaces and compressors (brands or models), especially ones that are long lasting and/or energy efficient. We'd also like to hear stories and or warnings about setting this up in an old house.

Not sure how old the ductwork is but it would be very, very difficult to make any changes to it, and I know certain systems may require upgrades to duct work.
We're replacing the furnace because it's at least 15-20 years old, is not a particularly good brand, and the home inspector told us that essentially once you factor in the labor cost of adding the compressor to the furnace it's worth it to just replace the furnace while we're at it.
I would be willing to sacrifice some energy efficiency for furnace longevity, since I figure the monetary and economic costs of replacing a furnace sooner would be greater than a small amount of inefficiency.
I keep spelling it furnance for some reason. I had to go through my post and delete at least have a dozen n's.
