Well its about that time. My central air is shot so im getting that replaced and figured i might as well do the furnace at the same time. We got quotes for 80% and 92% efficiency units made by amana to the tune of 1800 and 2400 respectively. Not bad prices. Im leaning toward the 92. Anyone have any comments on traditional 80% furnaces vs the more efficient condensation units? Any bad experiences with amana? From what i gather, any brand can be a lemon and proper installation is really the primary concern as opposed to which brand to get.
