    Why would you think a/c's would be any different. And they are not. You might get 10-15. And 15 is pushing it.
    Autos last about 3 X as long as 40 years ago ( 240,000 miles instead of 80,000).
    My "New" 9 year old, 112,000 mile Accord is about at _half-life_ or ALREADY 50% more than expected 40 years ago.

    My 14 year old TV provides a very nice, clear picture.

    I don't see why a very well maintained A/C unit shouldn't have a target life of 25 years / 20,000 hours in N. Indiana.

    One ought to expect a minimum of 18 years /30,000 hours for A/C unit in the South - but it takes a
    Good system, Great Tech and Knowledgeable / Vigilant Owner.

    Of course, if you wish to change A/C useful life to 6 years, just buy an ocean front home.

    Average human life expectancy is close to 80 versus ~65 years old of 70 years ago.

    If one changes their outlook on life expectancy maybe duration becomes close to "SELF-FULFILLING".

    There's that; and then there's government regulations and fierce pressure to drive down costs by using the cheapest material, oversight and labor (often over-seas) available.

    No way cars today are made like my first, a '72 Buick LeSabre with a 450...freakin' tank that thing was. Took me a whole year and a half to wreck it. Takes a whole lotta street signs to finally do in like...16 feet of US steal.
