has an answer for you. "...also get to benefit from more space, air conditioning..." This means that the old cabs have no AC.

It may be that the new cabs have more control over ventilation, separate from the rest of the interior.... but....the old cabs were within the coach's HVAC, and they most certainly had the benefit of the coach's.air conditioning.

Your interpretation of his statement is incorrect.

The old cabs have A/C. There is an overhead position-able vent in the cab, in fact.

What they do not have however is their own controllable A/C. On the new cab cars the crews can set the temperature level independently of the rest of the coach.

If the crew wanted to increase or decrease the level of A/C - or heat, for that matter - on an old car, they needed to adjust temperature the whole HVAC unit at that end of the car.

So you're saying that the cab door was open to let the A/C in?

Well the air conditioning is siphoned through the coach, though those little vents you see above the lights on every level.

I think it’s safe to assume air conditioning was also vented into the cab, but couldn’t be controlled separately from the rest of the coach like what was previously mentioned.
 
The old coaches have 1 condensing unit on each side, so in total 2. The new ones appear to have 2 on each side, 4 in total. Maybe the older cab cars had to share the HVAC system with the rest of the car since there were only 2, while the newer ones can have their own separate A/C because they have 4?

Okay. Got that.
