I'm considering having a heat pump system put in. I've heard that they are very efficient. I currently have an oil furnace combined with a wood stove. Does anyone have one? Did anyone have one installed? I plan on having my ductwork replaced as well since I recently discovered that they used asbestos on the seams, so I figure I might as well replace it, it's a simple set up and shouldn't be too over the top pricey.
