I no longer see the statement in the user manuals of the newer cars. Maybe
it went out with the switch to R-134 from R-12?

I think his '93 Honda has an R-12 AC system though.

Re: How long to operate A/C while in storage.
 

You are correct most modern AC system do have a ambient
temperature restriction, your government at work, but it
is 35 degrees not 20. Only applies in the AC mode not the
defrost. In defrost mode the AC only cycles enough to chill the
air before the air passes over the heater coil. The restriction
is EPA mandate that applies to the manufactures of ALL new AC
systems sold in the US. It is part of the regulation that
restrict the sale of toilets and washing machines to the amount
of water they can consume, as well.
Soon the only cloths washing machines one can buy will be
front loaders that will cost over twice as much to buy. ;)

no.

The purpose of AC is *not* to chill the air. The purpose of AC is to
dehumidify the air. That it does so by chilling is almost
inconsequential.

This isn't a good idea. Not only is that not long enough to allow
the A/C to the oil around and lube its seals, but it is also
EXTREMELY bad for your engine and exhaust system. You really want
to run the engine long enough to come up to full operating temperature
and then stay there for at least 10-15 minutes.

Some vehicles turn the A/C on with the defrost position. Plus if you
have the old style separate manual A/C button, you can turn on the
A/C and the heater at the same time so you don't freeze while
setting there with the car running. This warms up the inside
enough to allow the A/C to come on....
