Building a new house, 1.5 story and looking to get the most bang for my buck. Doing 2x6 walls with polyseal spray and cellulose insulation. Will a 16 Seer be worth the addition $3-4 k I have been quoted? Energy prices here are currently 10-12 cents per kw hour, but do rise occasionally. I am most concerned about home comfort though and have been told by some folks that higher seer units in this humidity are not worth it. Any thoughts?
The house is appx 3500 sq ft with 2700 down and 800 up. I am looking at two units, a 4 Tom down and a 2 ton up.
I am also interested on thoughts on the necessity of a fresh air inlet. I am not using spray foam and will have an unconditioned attic, but I am using the polyseal and spray foam at all windows and joints and using the airtight can lights. I am trying to get as tight as I can for less cost. Not sure if that is tight enough to need a fresh air duct in AC. I don't think the environments for living homes are doing this and they are using similar sealing methods.
