That way your A/c investment is protected.
35 deg F at what ambient temperatur? I'm in Fl too, and getting about 50 deg when outside is 90. Thats' with the windows open so I can test direct cooling, not looped cooling if you know what I mean.

15 minutes is not long enough. you would need a 100+ micron pump to get the moisture out that fast. 1 hour is considered the least amount of time. With that venturi pump I would say let it run all night.
Also did you flush the system?
How much oil are you adding?
have you ever heard of Nylog?
If not then you should do a seacrh and read some of the AC threads in the archives.
