My Carrier air conditioning units are almost 9 years old and the copper

that there are issues with the coils rusting out prematurely. Carrier use
to
have all aluminum coils and aluminum never rusts. Carrier and other
manufacturers realized if they switched to copper coils their customers
would
have to replace their coils approximately every 6 to 8 years (10 years if
you
were lucky). So it all comes down to what's called "Planned Obsolescence"
and
you see it practiced with almost everything you buy these days. It just
puts
more money back in the pockets of the manufacturer and repair industry.
He also told me that Carrier and others are starting to bring back aluminum
because of the backlash from customers. I am now getting aluminum coils
installed.





LOL Copper does not RUST.... Hilarious
