Larry, don't the bubbles mean the system is at least trying to cycle? I thought I felt cooler air last night, but the evening air was pretty mild and from what I read this system draws in outside air...so I got a firm maybe!

Yes, I am gonna have the system put on a vaccum pump,evactuated, and recharged.

Now, is there any other way to test this system BEFORE I re-charge it? I'd just as soon not throw money into the system and then have it leak back out into the air!

Also, I'm still not sure about the vaccum motors that run the flaps, but I'll be testing all that next week.
