After going to a class on these mod furnaces, my company and I can't figure out why any one would want to buy one.
First off, the tech rep said that there is no gas savings with the modulating furnace over a standard 90% furnace, the only savings is in electic unless you use a 2 stage t-stat over a modulating t-stat. (Then what good is a modulating furnace?).
Second, the problem with the furnace taking almost a hour to go from 40% to 100%. He said this is a real problem for people that just want to take the chill off. It won't do it unless you know the work around as he put it.
So, what is it with this high price furnace? I don't see it. Some one please explain.
