In 2 of the 4 estimates for a new furnace for here in Southwest PA, the answer is yes. This house is a Cape Cod style and was built in 1950. But then 2 said I'd need over 100,000. So I'm wondering too!
I am assuming you mean 80,000 output, not input. An 80,000 input rated at 80% efficiency only has an output of 64,000. A 95% efficient 80,000 input will give you 76,000 output. Go with the people who did a proper heat loss calculation on your home since any two 1800 square foot houses could have different heating/cooling requirements. You also don`t want to oversize either. When I replaced mine 3 years ago I went from 100,000 to 52,000 and those are the input ratings at 80% & I`m doing just fine.
