Garage doors lack insulation, but you can do something about that.
I live in South Florida, and while it doesn't get as hot as in Texas,
it does get hot. We added insulation to our metal garage door in the
form of Styrofoam insulating panels slipped into the inside of the door
ducktaped in place. Fiberglass insulation with the cardboard backing
would work as well. (Which has the better R value??). You might have
to re-balance the door after adding the insulation, but in our case
the garage door opener didn't seem to care and isn't straining. The
insulation lowered the temperature in the garage during the summer by
at least 10 degrees F.
================================
Normally this would be OT in this NG ,but mentioning styrofoam =
polystyrene , it is veeeeeeeeeeeeeeery flammable and if used in an
enclosed environment ,people inside would be in real trouble when a fire
broke out. Insulating material should be fireproof or at least flame
retardent while not emitting toxic/suffocating fumes.

My garage door is of the insulated type. It has some sort of
fiberglass stuff
like you get in those 4x2 ceiling tiles.... It is redundant and I
think more of a
sales gimmick than any real barrier to heat transfer.....

Regarding roll around air conditioners..... I like the idea a lot,
but they
are very very very expensive compared to a vanilla window unit....
Home Depot sells a window unit here for about $80 USD while the
cheapest
roll around I have seen is over $300 USD for about the same size....
A crafty ham would buy a window unit and then build a little roll
around
cabinet with some dryer vent hoses to make his own. After all, most of

the fun is building stuff, even if it doesn't look like a "finished"
product.....

( I am a big fan of The Red Green Show :)))) )

I am doing something like that in my attic ---- running the intake
duct
from the cooler garage below and the air exits into the attic, which is
already
hot so a little more heat won't matter..... Not a roll around, but a
ducted
cabinet....... But then I have nothing better to do all day except to
mess
around with this stuff .... probly not a great idea for everybody, tho.
I go thru a lot of duct tape..........

Just my dos centavos.....
