yes. When I had my system redone, the shop required me to have it to them by mid-day. They evacuated the system, leaving gauges in place overnight. meanwhile they were doing non-air conditioning, scheduled work on other vehicles. The next day, after determining no leaks, they then went ahead with my conversion.
