I love air tools and pneumatic stuff but it's incredibly inefficient. I can't think of anything that is less efficient.

This is correct. To put some numbers on that 100 CFM, the Ingersoll Rand RS18i air compressor is rated 113 CFM at 110 PSIG. It has a 25 hp (18.65 kW) motor.
That's 18.65 kW of power to get 1.8 kW (6000 BTUH) of cooling, so the EER is 0.3. Window air conditioners have EER about 10, so use about 1/30 as much power for the same cooling.
