The furnace on the left was installed 2011 I have checked and serviced from day 1 every year looks and operates like it came right out of the box.
Unit on the right installed in 2016 by someone else.
Checking is important. They skipped a couple years and now i can’t reverse the damage. Leaking everywhere and on 96% efficiency furnacesthe water is very very corrosive.
Open those doors yearly and check them.
