I have several quotes for a York Affinity series 16 3 ton or a York LX series 14.5 3 ton. The problem is to get a rebate from the local Electric Co. the unit must be a 16 seer unit. My installer says the York Affinity series 16 only outputs at 15.75 seer, but the York LX series 14.5 outputs at 16 seer when matched with ecm blower, according to AHRI ratings. Both units have 10 year warranty on parts and labor. I have read the York Affinity series 16 is a better unit. The furnace will be a 80,000 btu 96%. I am confused. I guess it depends on matching air handler, blower, furnace, etc.. to get a seer rating?
