On my freightliner chassis there is a vaccum pump that goes to an accumilator tank, the little black baseball sized tank, then to the controls of the heater/AC system. The on/off valve that shuts the flow of hot water on and off for this system ex: is run off vacuum.
Not being argumentive here, but thats just how it works.
The air pressure system on mine is for the brakes and the airbags that support the coach and give us that comfortable ride we enjoy.
