1 unit or 2 on New Construction?
Good morning all,
My wife and I are building a two story 2800 sq ft colonial. Originally, the house was spec'd with 2 heat pumps and 2 air handlers. Due to budgetary constraints, it looks like we will only be installing 1 zone for the whole house. What we are wondering is how much more energy will be used to heat and cool with only 1 zone? How much merit is there to using automated louvers to do the zoning on the single unit?
I'm thinking this may be more of a summer issue than in the winter - we will have a relatively powerful wood stove in the family room which will keep the downstairs relatively warm in the winters.
