I'm in the process of trying to select a manufacturer of a home heating and whole house aie conditioning system (70000 BTU furnace 2-3Ton A/C) to replace existing units of 28 years and 35 years. I've had a number of contractors in all quoted close to size I stated, but the info I got doesn't help me with troubles that may have occurred in the past. Quotes are from Goodman, Carrier, Bryant, Heil. Any help on trouble free selection or is this an oxymoron.
