Yes this I do not understand, my AC and pressurization is on after I start the plane and stops when I stop the engine, and my cabin is cool and fine like this. Ronald Stevens 786-338 1678
I don't pressurize until I get up to 6-8,000 ft. This keeps my cabin a bit cooler and comfortable at low altitude and doesn't steal power when it's needed most ie on takeoff and early climb out. Do others do it differently?

>>> I'm looking for a minimum thickness vacuum hose just to hold the dukes pressurization valve open on takeoff. Right now I have a 1/4" i.d. .64" o.d. big fat rubber line. I don't see anything on McMaster Carr that is thinner wall. But given it probably needs to handle maybe 10 psi of vacuum, the big fat rubber hoses seem like overkill.
