we installed a maytag 2 speed variable gas furnace 14 months ago and it hasn't yet gone more than 58 days without an emergency service call. The HVAC contractor finally agreed to pull it and I will pay the difference for either a Trane Model #XV80TUD100R9V3K or a Lennox (Elite Series) Model #G60UHV-36B-090. My repair guy says Trane, hands down for reliability. We would be paying an additional 1200. What is your feeling?
