ugh - this whole process is annoying. anyone want to chime in on lennox g71 or rudd ultra 95(climate masters), trane (air masters), or kenmore furnances (sears)? we are looking for 95% modulating gas valve variable speed. we are keeping the house for 5 years and then we might keep it as a rental for another 5. need something that can accommodate two floors (basement and main floor) as the basement is a living area.
