I have two bids for a new gas furnace and central air conditioner. One is for a Trane XL80 2 stage 2 speed 80,000 BTU furnace with a Trane XB13 2 ton A/C and a Honeywell Vision Pro Digital Thermostat. This system has "lemon guarantees" - if the heat exchanger fails during the furnace's lifetime, the entire furnace will be replaced free and if the compressor on the air conditioner fails within 10 years of installation, the A/C will be replaced free. Plus 5 years on the condensor coil, evaporator coil and furnace parts.
The other bid is for a Bryant Plus 80t Model 312 2 stage 70,000 BTU gas furnace with a Bryant Quantum Plus Model 591B Puron A/C with a digital setback programmable thermostat. This system comes with a 20 year guarantee on the heat exchanger, 5 year parts and 5 year compressor guarantees. The salesman did say this system is very quiet. (quieter than the Trane???)
We live in Indianapolis so we have hot summers and cold winters. Our house is small - only about 950 square feet.
Can someone with some knowledge of these things make some sense of this for me? Which one would be a better system? The Trane system is more expensive than the Bryant system but with it's warranties, it could be worth it. Any help will be appreciated.
