Hey Steve, I just used part of a can of Dust Off Freeze Spray
this afternoon to find a thermal intermittent on a radio - the
stuff is 100% R134a - I guess I must not care about the
environment? The instructions
on the can say to apply directly to components to locate
thermal intermittents, they don't say anything about recovery.

I am confused about caring about the environment - the front
of the can says 100% Ozone Safe - and I just bought it brand
new about a week ago.

My wife also wants to know if she hates the environment
too - her hairspray can uses R134a as the propellant.

My kid also wants to know if he hates the environment too - he painted
his bike with spray paint last week - propellant is also r134a
in that can.

What the hell? If you vent the system down to atmospheric then how
exactly does appreciable amount of outside air and moisture get in
and ruin the dryer? Unless you vent it then remove the schrader valve
perhaps and drive around for the next week with the system open.

That much is true - if he gets a new compressor - but you forgot
the money for all the extra parts and time he needs when he
fragments the compressor and it dumps metal filings into the refrigerant
lines.
