We have a duplex. How much would it cost for a gas forced air to replace the gas boiler system in a 2 story house. We want a furnace for both stories. One upstairs and one downstairs

Too many variables to even give you a ballpark quote.

Your location is the first thing determining price. Then there is how much work will need to be done to get the duct run and what level of efficiency furnaces you want installed.

Are you wanting AC as well?

Another thing to consider is if there is any asbestos covering the boiler pipes now which may be disturbed, unless you are just going to leave the boiler and existing piping in place.

Your best bet is to call a couple of local companies and get free quotes...make sure they do a load calc!
