I am in the process of replacing a Lennox G20 propane model (100,000 btu) furnace in our 16-year old, 2,500 square foot, two-story house with a new Lennox G71 or G61V (90,000 btu). The difference in price between the two models is fairly small (the G71 is about 8% more).
Q1. Is the upgrade to the G71 worth the extra money?
Q2. Given that the G71 is a relatively new model does anyone know of any glitches in this model that would favour purchasing the G61V instead?
Q3. Has there been any issue with the propane conversation kit for the G71 or G61V unit (e.g., lack of pressure that leads to ignition or other problems)? Currently I have a ½ inch leading from the propane tank to the regulator mounted outside the house.
Your help and comments would be appreciated.
