We recently purchased a 1976 Coachmen Motorhome in overall
excellent condition. One item in question is the truck A/C
system. (not the overhead unit) This motorhome is built on a
Chevy Van G30 chassis. It had sat for 7 years and has the typical
water damage but fortunately nothing severe.
Currently the A/C system does seem to provide a little bit of
cooling. However it is no where near where it should be. I'm
guessing that it is likely to be low on R-12 freon. I've been
researching alternate products on the web and have found products
like Freeze12 and Autofrost R-406A that appear to be good choices
as a substitute for R-12 with Autofrost being the likely better
choice.
Anyone have any experience with any of these? Any pros/cons to
think about? I have read where you need to totally evacuate the
system before introducing the replacement gas. Anything else I
should be aware of?
TIA
