How well does the air conditioning work in the Prius ?  I live near
Houston, Texas where we typically run the A/C in the car for 8 to
9 months.  From June through September the A/C will be set on
MAX due to the 100 F average peak temperatures.  The night
time minimum is not usually lower than 80 F.

I live in coastal Southern California so I don't regularly challenge the
A/C, but I have done a little driving in the desert during the summer. The
A/C kept the car comfortable at temperatures in the high 90's and low 100's.
It is hard to tell how much impact the A/C had on fuel economy because these
trips involved quite a bit in the way of climbs and descents. I generally
leave the A/C in automatic even near home to dry the air and keep the
windows from fogging up. I did run without the A/C for a period of time just
to see if the MPG improved. I didn't really observe a significant difference
in mileage, but then again, I had to periodically run the air conditioner to
clear the windshield.

Another Californian -- but from the hotter Central Valley where it hits
upwards of 110 in July/August.

No problemo here.  Works quite well.  Basically, the compressor is
electrically driven much as the refrigerator in the house.  You set it to
where your comfort level is, maybe 76 degrees, and the fuzzy logic of the
computer takes over to maintain a comfort level equivalent to 76 degrees.
Mine is a white one since black cars here suck in the heat (although they
look cool when clean and waxed well).

The engine may kick in once in a while to keep the electric to the
compressor going, fwiw.  You can sit in a parking lot for a long, long time
and the thing keeps the interior quite cool.

Mine works very well in Dallas.  Using a Sunscreen in the windshield
speeds the cooldown.

Very well.  I live in the Phoenix area, and I usually leave it set to 75
degrees year round.
