I can definitely hit the low-mid 30s reliably on the discharge air temperature even when it is high 90s to low 100s in full sun, as it has been the last several weeks here.
Ok here are some more hints, a member PM'd me and I thought I would share these with everyone...
I would also recommend ordering/obtaining the following:
New carbon and pleated cabin filters. The carbon one makes a huge mess when you go to change it out inside the car, this way you can do it outside the car.
BM-210-0007 cover lock tool from Pelican - you need this to remove the retaining ring around the key switch. Looks like the Rook in a chess set. You can fake it with a couple small screwdrivers but this made it nice and easy.
DIN radio removal keys, you will need them for the stock radio and the climate controller.
Panel removal wedge kit at Harbor Freight, for removing interior pieces. Go ahead and pick up the green HBNR o-ring kit while you are there, in case you lose/damage one of the o-rings that come in the compressor kit. They also have a steel hook set, you will need a hook to slip in behind the instrument cluster and pull the cluster out of the dash board. It is friction fit in the opening and you have to pull quite hard the first time to free it.
If you have any light bulbs out behind the dash now is the perfect time to change them.
PAG46 oil, I would get two 8-oz containers, use one to flush the compressor and then the other to lube the o-rings and do the oil charge as you put things back together.
Something that can make precision measurements of oil. Check with your pharmacy, they should be able to sell you a syringe without the needle.
plastic film or bags and rubber bands - to seal off the ends of the lines after you flush/oil them, take them off right before you make up the joint.
1 gallon G-05 coolant and 1 gallon distilled water - you have to drain the cooling system.
Watch the youtube video many times and step through it frame by frame.

On the expansion valve, the existing expansion valve has a stud that holds the hose retainer in place. Your valve will come with a tapped hole and no stud. They show in the youtube twisting the stud off the old EV and putting it in the new EV. Not so much in my case, that thing was frozen in place. So I went to Lowe's and picked up some socket head cap screws. I cannot remember the exact length I ended up with, I bought several different lengths along with flat and wave washers. So instead of putting the nut on the stud to hold the hose retainer, I used a screw. Bring your nut and confirm on the thread tester board the correct size. Pretty sure it was M6x1.25. Don't forget to pick up the vinyl tubing to rebuild the box drains too.
You will have to Dremel off some of the internal molded ribs inside the evaporator box to make the new evaporator fit. Don't forget to transfer over all the rubber bits from the old to new evaporator.
The heat core will pee everywhere. Even if you turn it upside down 10 times, it will pee some more when you start taking the box apart, so be careful if you bring it in the house to take it apart. Be careful removing the clips, they will launch into low earth orbit if you don't keep a hand on them while prying them off.
And when you fill the cooling system back up, be sure to burp it. I would fill from the disconnected upper radiator hose toward the head until it cannot take any more, then finish filling from the expansion tank. The first time you restart the engine be sure the EC button is lit up before cranking (so you don't run the compressor before charging) and crank the heat to HI. Keep an eye on the temperature gauge and drive around for a bit. Try to go up and down a couple of hills if you can. Make sure the heat actually gets hot as the temperature rises. This forces the air out of the heater core. Now you can focus on recharging the system. If you just went straight to charging on your first restart, then there is a chance you could overheat the engine due to a big air pocket getting pushed out of the heat core and getting trapped in the head.
And one more thing, I have a confession to make...
I was tempted by the "Rock" due to their lower prices. But the parts are all Chinese and you could tell it was really cheesy stuff. If I had to do this all over again I would have definitely spent the extra $$ and gotten the parts from Pelican...
