I know this topic has been discussed a million times here, but the more I read the more confused I am!
My needs are simple: 80% eff and reliability.
1. 80% efficiency
(Too complex to explain but I want 80% eff furnaces)
(Yes, I want a reliable furnace; not 5-6 service calls per winter!)
- The Lennox G40 or G50 seems OK but reading this forum, it seems like people have problems with it?
- Carrier 80% seems OK too? But which model?
- Goodman GMS8 Series 80% seems to be the most used in this forum:
So, please help! I need feedback (good or bad) from homeowners and pros, what 80% eff units they have and the pros and cons.
Yes, the furnaces will be installed by HVAC contractors but I need feedback from people.
