I purchased a Keystoker Coal Furnace 160K BTU (Direct Vent) to install in a four year old 2,650 Sq. Ft. ranch that is currently heated with a High Effic. forced air propane furnace. (My plan is to run the coal furnace through my existing forced air system duct work). The coal furnace will be direct vented. I have gotten two estimates to duct the coal furnace into my existing duct work and the estimates have ranged from $1,200 to over $2,000, (much higher than expected). Does anyone on the Web Site have any contacts in the Syracuse NY area of someone who might be knowledgeable of "coal furnace installs and how to "best" install into an existing (forced air system). I have had a very hard time finding an installer in the Syracuse area willing to look at a coal furnace installations and with the two estimates being so high, I'm thinking of throwing in the towel on coal.
