I am in the process of evaluating a 95% variable speed, 2 stage gas fired furnace and a 16 Seer, 2 stage heat pump. I live in PA not to far from the Maryland/PA border. 3 of the companies and units I am considering are Bryant Evolution series, Am Standard Heritage and Trane XL. The Bryant installer provided these number and sent me a copy of the ARI certified performance sheet, showing the model numbers of the equipment, the Trane dealer provided me the numbers for their system and I am guessing the American Standard system would be about the same as the Trane system since it is the comparable Am Std equipment to the Trane equipment.
All systems would have a 10 year parts and labor factory warranty and would include the same installation as far as material etc. All installers have been in business for a minimum of 20 years and to the best of my knowledge and research have a good standing in the community.
My questions are
1. Will I notice the performance difference of the Bryant in my electric and gas bills and I am guessing they would be less? Or is the difference insignificent?
2. The Bryant is about 7% less expensive than the Trane unit and about the same as the Am Standard unit, is there a reason to consider Trane or Am Standard over the Bryant unit?
3. I have dealt with the Am Std dealer for other plumbing needs, but have no difficulty dealing with the other installers.
Your opinions please.
