help- fair deal or ripoff?

[carcajou1]

I am building a custom home.
1] Included as standard is a Carrier Performance 5 ton AC ["tag at my house will read SEER13"]. I was offered an upgrade to the Infinity 21 ["tag would read SEER 17 for my house" he said] forXXXX- fair deal or ripoff?

2] Separate trunk for masterbedroom with damper = $X,XXXX upgrade.

3] Honeywell Pro 5000 thermostats included, Pro 8000 upgrade at additional XXXX each. If I took the Pro5000 could I replace it later with a Pro 8000 and do it myself?

Have sympathy- I'm a layman retail customer

Here's a calculator (http://alltemp-hvac.com/calc/seercalc.html) that will help you see if the cost of the higher efficiency unit will pay for itself over time...

The higher end systems generally have variable speed air handlers which increase comfort and make a vast improvement in the ability of the system to remove humidity. So even if the system won't "pay for itself" w/ energy savings, there's this benefit to consider...
