I need to replace my 46 year old HVAC this year, and have started getting estimates. ~100,000 BTU, central air, a couple of grand of duct mods to include the addition so I can get rid of the wall furnace out here. (duct mods are expensive due to concrete cutting required for access to addition crawlspace.) Yes, they are measuring house to do do load calcs, etc. So far, I have been quoted 7200 for Lennox 92+, and around 5500 for Maytag 90+. New furnace, A-frame, outside compressor, etc. I plan to call a couple others in next week.
Looking for opinions from people who do installs and repair work- given that I don't wanna spend a fortune on this 1960 cookie cutter with original furnace, but I do want decent reliability, what brands should I avoid? On a vanilla system like this, what brands give best bang for the buck? I won't be here long enough (est. 7 years) to get a payback just from the gas bills, so I do want a reputable enough brand to recover some of the cost at time of sale. IOW, not crap, but I don't need gold plated.
Any advice greatly appreciated.
