Hi all,

I'm a H/O looking into replacing a 25 y/o Lennox furnace and A/C. House is a 55 y/o, 2500 sq. ft. ranch in the Pittsburgh area.

I've had multiple quotes with multiple manufacturers, and I have it narrowed down to two. I have about equal confidence in the contractors.

Option #1
Ruud 2-stage ECM motor UGRM10 105k BTU Furnace
Ruud 16 SEER 2-stage UARL048 48k BTU A/C
w/ 2-stage Ruud control and Aprilaire 2400 media cabinet

Option #2
Bryant Evolution 3-stage ECM motor 355CAV 120K BTU Furnace
Bryant Evolution 17 SEER 2-stage 187ANA 48K BTU A/C
w/ Evolution control and media cabinet.
This costs 18% more than Option #1

My questions are these:
Is the Evolution system worth the price jump for seemingly comparable equipment?
Will I get the most out of the Ruud system with a simple 2-stage Ruud thermostat(200 series)?
