I have to make a quick decision on my replacement furnace. My previous post discussed my cracked heat exchanger and the utility co. came out and red tagged it today. Luckily my gas fireplace cranks out some good heat. After receiving several quotes I'm down to 2 furnaces. Calc's have been done to size the units. The two furnaces are:
1) American Standard Gold ZM, 2 stage, variable-speed, 60,000 btu.
2) Carrier Performance 59TP5, 2 stage, multi-speed, 60,000 btu.
Both quotes are very, very close in price and both dealers have been around for decades. Carrier installer is more well know locally. The American Standard guy has been doing this forever, seems very sharp and is actually an HVAC instructor at the local community college. The Carrier guy said that he's confident that the competition doesn't hold a candle to him in terms of quality of install as well as the professionalism and knowledge of the installers. I realize that option 1 might be a better unit based on it having a variable speed fan, but my gut is for some reason telling me to go the other way. Can anyone give me suggestions on which system to go with based on experience with either?
