Seems like lots of AC discussions go on in the summer...

I just had a new pump put in, and new refridgerant added.  $800 later, I
thought all was well.  However, I am getting some leaking from the
overhead cabinet after about 30 mins of use.  I asked my mechanic, he
said the drains are either blocked or disconnected, and its a world of
hurt to remove the cabinets and take down the housing to get to them.

How big of a project is this?  Can it be done by one person?  The
Bentley is forboding, mentioning jacks and assistants.  Is all this
really neccessary to reach the "drains"?
