[quote=Anonymous]They might be better now than before, but they still are not great in winter cold in metro DC. Our HP really struggles just to maintain 68 F once the outside temp drops to about 20F. Ours is a major brand, high efficiency, and about 8 years old. House is heavily insulated - spray foam in walls, insulated windows and doors, etc. A previous house had a better setup. 2 zones. Gas furnace was downstairs and HP upstairs. Heat rises of course, which meant warm air from gas furnace would rise to help keep upstairs warm. HP had optimal performance for summer cooling - and cooler air tends to fall. [/quote]
