New home build- should I upgrade HVAC?
My wife and I are thinking of building a 3 bedroom ranch with Beazer near Indianapolis. They have an "eSMART Green" option that is a $3,000 upgrade. What that includes is increased exterior wall sheathing and insulation (not sure on rating bump as info on this is not clear); increases attic insulation to R49 (from??? don't know); bumps the furnace from 90% efficiency to 95%; 14 SEER AC to 16; htere might be some other small things like jumper ducts, etc...
I am tryihng to determine if this is worth the cost. In Indy we get extreme weather in Summer (it will hit 100F) and Winter (it will hit -10F). Any opinions?
