Which type of duct system has the longest life expectancy?

Boilers have a much longer life expectancy than furnaces, ranging from 20 to 35 years. If the heat exchanger begins to leak, they are usually replaced. Heat pumps will last anywhere from 10 to 20 years, based on how much they are used, but 15 years is the norm.

Should I replace metal duct with flexible?
