The AC doesnt use much power at all. Just because it was 90 degrees outside doesnt mean your battery was warm (it almost assuredly wasnt, if you drove 25 local miles at 25-45 MPH).
There seems to be some confusion amongst BEV owners that running the AC (regardless of mode... heating or cooling) really gives you a range hit. But as JJ has pointed out, cooling the car down is *very* efficient, and uses very little energy; it takes a lot less energy to move heat from one place and put it in another (like when you're cooling off your car), than actually using energy to *create* heat (like using a resistive heater in your car in the winter).
I live in the desert. We hit 100 degrees for our first time in mid May, then from June 1st until the end of September it's over 100F every day. And I keep my car at a very comfy 65F during the hottest days of the summer, and take very little range hit from it. Honestly, I'm very impressed by the cooling capacity this car has. It's the first car I've had since R-12 (an older type of refrigerant) was banished that's actually been able to get the car *cold* during the hottest days of summer.
My previous car was a 2016 Honda Accord V6, and it really struggled during city driving to keep the car temperature down to where you wouldn't break a sweat while driving it. It would run the fan full blast and never really get comfortable. Not so with the Model 3. The hottest day I drove it was one day in August in Las Vegas. It was 124F outside. My car had been parked in the sun while my wife and I ate lunch. We were pretty new to the car, so I didn't even think of turning on the AC as we were finishing our meal. Even so, the internal temp hit the desired 65F within 20 minutes, at which point the fan actually started to slow down. The cooling capacity of this car is truly amazing.
You young guys missed out... The old R-12 air conditioning systems in older cars was truly amazing. It would freeze you to the bone on the hottest desert summer days. But losing out on the benefit of a nice cold air conditioning system is a small price to pay in exchange for keeping the ozone layer.
And as JJ also touched on, the preferred operating temperature of our car's battery for maximum efficiency is a lot warmer than most people would think. "Ludicrous" mode on the Model S heats the battery to 123F! I don't imagine that the "normal" operating temperature is *quite* that warm, but it's still pretty darn warm.
TL;DR: Use that awesome Tesla air conditioner to your heart's desire on those hot days, and don't even worry about taking a range hit for it.
Back on topic... I also drive 138 miles one way to work, but I don't do it on a daily basis. I drive to work, the car sits for three or four days, then I drive it home. I do have to stop at a supercharger for ten to fifteen minutes before the drive home, but I love our Tesla so much that I just don't even care about the minor annoyance of having to stop.
