Simple if you look at it that way. Let's say it costs $2000 more to
go to a 90+ unit and that you would reduce your current energy usage
by 12% (10/80 = 12.5%, not 10% savings) which amounts to $100 based on
last year's bill. So your $2000 investment generated an after tax ROI
of 5% at LAST year's fuel prices. Is it a good investment?
