Anyone out there replace just the secondary heat exchanger? how bad is it? this things a 1996 rust bucket but she's still in warranty. i'm doing it free for a friend but am starting tothink a new unit may be easier. Thanks Al O.

It's not too bad. Plan on 2-3 hours for your first one. Carrier will pay about 450 for the labor. If you are not set up to receive labor warranty from carrier, it might be easier to have your friend call a carrier dealer, who will do the job at no cost.
