I realize may not be providing enough information to have this answered, but I will ask anyways.
I live in Winston-Salem, NC. Our house is a brick split foyer with ½ the basement finished and the other ½ a garage. Its about 2100 sq ft. Decent attic insulation. We have a 25+ year old AC and a 14 year old 80% propane furnace. The AC is 3 ton. The furnace is 100,000 BTU. I am thinking about replacing everything with a heat pump.
My question concerns the BTUs from heat pumps. If we get a 3 ton heat pump to replace our current system, will the heat output be approximately 36,000 btu? Even if I assume our 100k propane furnace is way oversized, 36k is a whole lot less than 100k. That's a lot of BTUs to lose.
Its entirely possible I am way off base on this, so please forgive my ignorance on this subject.
