With both contractors being equal (both highly recommened)and priced in roughly the same ballpark, Trane slightly higher..
I am having to choose between:
All Trane XL19I system (2x3ton + 2.5ton) with 90% XV90 Furnaces
Rheem Prestige (2x3ton 18 seer & 2 ton 16 seer) with 90% RGTA Furances
Located in Dallas, TX 3,400 Sq. Ft. Two Story Home
#1 concern is comfort and humidity control
#2 long term performanace reliabilty
#3 Economy of operation
