From another resident of a hot climate - you will get better (read faster)
results if you let it go into recirc and crack the windows several inches
for the first couple of minutes. The AC will cool faster and convection
(warm air rises) plus whatever breeze there might be will draw the
superheated air out the windows.

Thanks for that idea - I'll try it. Fortunately, the temperatures around
here in southern Arizona have suddenly cooled to "humane," so really I'm
hoping I don't have to get a chance to try it until next May.

Bah, this is still unclear to me with no concensus on the best method. It
is agreed that opening/cracking the windows when first driving will evacuate
the heated air, but afterwards there are 2 camps.

1. Start in recirc and then switch to fresh after temp stabilization.
2. Start in fresh and then switch to recirc.

I think 2 is more intuitive and that's what I do!

That's what *I* do, too. Now, here are excerpts from the (Accord 2004)
MANUAL. Remember that thing? ;)

* If the outside air is humid, select recirculation mode. If the outside
air is dry, select Fresh Air mode.

* If the interior is very warm, you can cool it down more rapidly by
partially opening the windows, turning on the A/C, and setting the fan to
maximum speed in Fresh Air mode.

HAH!

Re: Why do vents default to outside air?
 

How about reading to owner's manual, it's all in there in my book. The
manufacturing
engineers wouldn't have put their recommendations in there if they didn't
think it
would help the owner.

Hmmm, if you say so. Certainly my '94 Civic does. ;-)

I don't see why there should be a "camp". Get out your thermometer and a
stop watch and try it both ways.

I would be willing to bet that number one will win, and is, in fact, the
recommended procedure in every owner's manual I have seen in the past 15
years or more.

It is not the recommended procedure in any owner's manual I've seen in
the last 15 years, and I will take your bet.
