It's not even a good idea accepting the numbers as given.
The savings stated were $2300 over 15 years. That
new furnace is gonna cost $4,000 TODAY. A new furnace
today has a life expectancy of 15 years, maybe 20.
So, you'll likely never break even. And that doesn't
even factor in the time value of money.


Sheeeesh! The comprehension skills of some people are extremely lacking.

Norman didn't suggest that you replace a working 80% efficiency furnace.

But if you have to replace your old furnace, it only makes
economic sense to replace it with a 95% model.

For example, here's a 80% model for $662

and a 95% model for $872
