What condensing furnace product should I buy?
I feel I need to replace my natural gas forced air furnace (Lennox G8) now 35 years young with a condensing furnace. I have 2 quotes from 2 contractors at near the same price... an Armstrong model 95 V 95% 2 stage variable fan (apparently owned by Lennox) and a Frigidaire FG 7... I have combed various forums and sites to try and garner some data on which unit maintenance & repair records are better... or is Carrier a better unit... can you help this Albertan?
