If you're really feeling exuberant, send the kid up into the attic while you vacuum the drain on the outside to make sure there is suction up at the drain pan end - if not, figure out where the clog is and unclog it.Thanks for posting back with the results!

There is a huge suction device attached to the main ducts near the furnace / AC blower.

You could try a suction cup mount like this:http://www.amazon.com/Panavise-809-Camera-Window-Suction-Cup/dp/B000246ST6Numerous other choices, depending on the size of your camera.Keep in mind an HD video camera is only 2 megapixels where most point and shoots are 8-12 MP and pro DSLR cameras are in the 16-18 MP range.

Addition: I'd read about the suction cup ones, but read mixed results (people either worshipped them or burned them in effigy) -- has anyone first hand experience with them?

If you need to Delay the suction, then the owner needs to talk to the bank, show them evidence of s contract along with showing Your ability to actually close, to get a postponement. 

Some cheap budget brands don't use txv valves at 13 seer and are using orffices and alomost no cheap unit has a low pressure cut out switch on the suction side which could save you long term.

We have no idea what state this in so no way to know if there is a redemption possibility, liens that stick in a tax suction, etc. a Local real estate attorney or title company is your best bet. 

AC systems condense moisture first, then cool the air if there's any capacity left over.Some systems may be limited as to how low the suction side pressure (and associated evaporator temperature) can go.

. :) Thanks everyone for your input, we are going to be knocking them back into place with these suction cups I found on Amazon and a mallet.

Mine are on the North End and as such are mostly Suction 8.
