The original Duo-Therm A/C's on the 20 year old Class A we sold last year were still working fine. I did replace the start/run capacitors on both with hard start caps a few years ago. The only other maintenance has been normal cleaning. The analog thermostats were replaced with digitals a couple of years ago, but that wasn't due to any failing on the part of the A/C's.
