MY OIL furnace finally gave up so im in the market for something else. Here is my situation. I have a ranch with 900sqft main floor and 900sqft walk out basement. The house has blown in insulation in the walls the attic has one layer of r-12 so I need to add some more for ne ohio. I was thinking about a hi efficiency propane furnace hooked up to my duct work with ac. I have a pellet stove in the basement and a wood insert on the main floor which heat very well. I need something to cover several weekends im away plus cover anytime my stoves are down. Is there a website that has propane prices inmy area? So what do you guys think? Are there any concerns? Thanks for your help
