Time to replace our 32 year old Lennox (3 cracks and (at least) 1 small hole in the heat exchanger. I've investigated all three online, and have gotten two installation quotes so far.
We've decided on an 80% efficiency, 2 stage variable speed,and it seems that the major difference between these three is the warranty, with Lennox having the best. Goodman is the lowest cost, but with a standard 5&1 warranty.
One company priced out all three without comment as to quality. The second company priced out the Armstrong and the Lennox and bad-mouthed the Goodman. Third company is showing up this afternoon.
In reviewing older posts I've seen comments referring to even older posts that the Armstrong has a strong reputation.
I guess I'm looking for newer opinions/recommendations. We decided against the 92% efficiency as, around here at least, they are nearly twice as expensive and natural gas is still cheap, and likely to remain so.
All replies appreciated.
