Advice needed: Most reliable 80% eff Furnace
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.
Two-Story Home + Basement
Furnace A: 1991 Tempstar 80% eff 120K BTU (1st floor and basement)
Furnace B: 1991 Tempstar 80% eff 80 BTU (2nd floor)
i would go with goodman it will last and it also has a more plesent price tag. plus they have a few differ sizes in 80% so garage attic or closet you have a choice. also i ve found that if you do have an issue they are realy good about tech support and returning phone calls.
The one that's installed correctly, will be the most reliable.
as homeowner and mom money matters alot for me this would be my choice as a senior tech this would also be my choice if price is not an issue go with a trane.
install is a huge part of good operation so true
Could you help me with the checklist for good install so I can go over this with my HVAC people to be sure they do a good job?

I'd say, use what beenthere said. My checklist will differ from someone elses. And the beat goes on.

Part of me wanting to use Tempstar again because this unit runs well for 18 years straight!
So, I do need recommendation re brand (Lennox vs Carrier vs Goodman vs Tempstar) and model number please!

IMO, I wouldn't get an 80% furnace that didn't have a variable speed blower. All the manufacturers you listed make one. It will be a slight price bump but you'll save electricity during both heating and cooling seasons and it will be quieter assuming properly sized ductwork.
if you have had good luck with Tempstar why change?
T8MPN model, works great!!
