Best Natural Gas Furnace?

Think I should change furnace,..35 years old!

Anything out there what will run this long or longer?
Was looking at a Lennox today at the home show, but not so sure with the heat exchanger, being aluminized steel? Was asking salesman how long it will last,..said about 15 years with yearly maintenance.
Looks like they want to rip me yearly! Haven't had outside maintenance done on my old one in 35 years, can change belt, filter or motor myself and lube bearings.

HEAT EXCHANGER
I'm thinking if something is better out there, like copper or stainless steel heat exchanger?

A good gas furnace should last 20-25 years. You are not going see anything made today that will last 35 years without some major repairs.

The better furnaces have lifetime warranties on the heat exchanger. This covers only the parts and not the labor. Most heat exchangers fail due to the furnace being oversized compared to the duct work. Heat exchanger design has changed from the old days in an attempt to improve the heat transfer characteristics and improve the efficiency.

Given the issues with modern furnaces (reliability, longevity, etc), you might want to wait until you HAVE to replace your trust old furnace.
