My new Bryant (Preferred) is their best model short of the super high efficiency I was warned away from (both on-line and the installers). It replaced a 1985 Carrier. I got a noticeable drop in my electric bill, like between $20-35 a month. It does not run as long as the old one either.
Most of my appliances are gas (except the old electric dryer I brought home from the Air Force in 1992, that is the only thing in the house that hasn't been replaced) (and it only gets run 1-2 times a month) (and now that I wrote that it will die next week) .
I wash and wax the new condenser (outside) because aside from the truck, it's one of the most expensive things I own.
