the labor warranty was only 1 year for the trane and 2 years for the lennox. !0 year for parts, etc. It was mentioned that the labor warranty can also be 10 years? Is that something the installer does separate from the manufacturer?
I read somewhere that the xl19i trane does not use the new freon substitute? Is this something to also consider? It is my understanding that the trane i was quoted and the lennox both use the freon alternative..,
