My sales guy was here tonight. Could use some advice from the experts. He quoted me three 80,000BTU systems.
1.) Bryant 359AAV. 95% AFUE.: Baseline cost.
2.) Bryant 355BAV. 95% AFUE + DC Motor + 2-Stage Heat : Costs 33% more than Option 1.
3.) Bryant 355CAV. 95% AFUE Evolution. : Costs 44% more than Option 1.
Evolution has too many bells and whistles and my AC unit cannot take advantage of some of the features it offers so OPTION 3 is OUT.
1.) Is the DC motor and 2-stage operation (option 2) worth the 33% premium. Those are the two features that stand out to me and sound nice.
2.) Should I be trying to find a lower efficiency unit that has the 2-stage operation and DC motor (i.e. are 80% units a lot less expensive)?
Gas is cheap around here. Going from 80%-95% will only save me $118 per year.
To complicate the matter, my gas company gives me a $460 rebate for getting a 95%+ efficiency furnace.
