I recently moved to DC and am wondering what the best heating/cooling system is for this climate. Currently, my place has a 2-ton heat pump that needs to be replaced, but I wanted to check with the experts before spend the money.
DC is in Cooling Zone 2 and Heating Zone 2. The averages I looked up estimate 935 cooling hours/year and 3784 heating degree days. The high temp in summer is 93 and the low in winter is 17.
I am concerned that the winter months in DC might be too cold for regular heat pumps, and that I might be better off with an RCC unit or "cold weather" heat pump. Price is an issue, but really I just want what is right for the space.
All of your suggestions are really appreciated, as are any recommendations for good HVAC contractors in the area.
