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