Variable speed blower and heater efficiency
I live in New Orleans (high humidity) and I'm about to choose an A/C and furnace for a new construction 2 story home using the new blown in foam insulation in the attic and walls. 2 questions:
1. I am going with two 2-ton 14 SEER Goodman a/c units but I need to choose between a variable speed blower or single speed. The v/s will cost an additional $1,000.
2. The heater/furnace is spec'd at a 95% A.F.U.E. unit. Is this high of and efficiency rating necesssary in my area?
