Did YOU measure 33 degrees or is that what the dealer told you? Did the dealer service it on a 60 degree day? If you're measuring 33 with OAT of 80 I'm scratching my head.
I've had problems with Dealer-serviced Bobcat A/C. Mostly, the customer just had it in and it's not working. Bad hose crimps, loose schraeder valves, etc, resulting in a lost coolant charge which is why most folks take it in to the dealer in the first place.
Anyway, like bobcatmechanic said, if you're still cold at the register, but the cab's getting hot, clogged cab filters, especially the outside one on the back of the cab(fresh air intake) could be the culprit. That should be checked as part of the service.
The air coming out of the register shoud be moderatley forceful, but hard to gauge unless you're used to what's normal.
The most I've ever got with temps on a Bobcat is 30 below OAT on a good, new system.
Texas being mostly humid and all, lift your cab and check the little rubber drain tubes on the bottom corners of your HVAV box. Sometimes they get clogged with dirt and can't drain condensation water, your evaporator will freeze up on the outside. This will also restrict airflow, but will also cause your compressor to cut in and out.
If you do a tint, don't go cheap if you want it to be cooler. Even if they don't bubble, cheap tints just look cool on budget cazoo cars, and don't block the rays that heat up the cab.
