I live in Maryland. I own a large rancher. Most of the main floor is heated by a hot water boiler. I also have a 12x30 addition that is heated and cooled by a heat pump. The heat pump also has a 10 inch return and 2 6 inch supply ducts running to the basement. This set-up has done a good job thus far of cooling these areas and removing humidity from my basement. My complaints are, like most people I talk to, I hate the heat pump for heating. It's noisy, uncomfortable and expensive!! It's really old and I think the fan went bad before I left home this past summer for Afghanistan (I'm in the Air Force).
Are newer heat pumps any better than the 10-15 year old "Comfort Maker" that I've got? If I do replace it with a new, high efficiency model (should I), what are some low cost, yet efficient means to add supplemental heat to the rooms when the temps drop? I was thinking of adding some electric baseboard heat, but I can't get a feel for how efficient they are compared to the heat pump. Does this make sense? I'd love sume ideas from you all before I search for contractors when I get home next month!!!
