Karl,
Congrats on the coach!  Chime in with your questions!

What AC units do you have in your basement?  SCS?  Can you describe what is going on with your ACs?

Bill,
I have the Dometic units.  The 2 front ones are stacked in the front compartment.  The lower one, (front one) blows alot of air inside, but outside all I get is a "grrrr" for 3 to 5 seconds.  When this happens then genny stumbles a little, but hardly worth talking about, it is a 20kw.  It sounds like it is pulling to many amps, plain and simple.  Could be a bad capacitor, bad board, loose,bad,or arcing connector, or the compressor is seized.
The upper unit, or middle unit runs, but does not seem to blow alot of air.  The PO just replaced the evaporator fan, and while reassembling it drove a screw into the compressor wall.  Had that fixed, recharged and working.  On the way home stopped working.  I found it iced up outside, with very little airflow on the inside.  Since then, little cooling and marginal airflow on the inside.  Freeze ups are typically low on freon or too little air flow.  The bedroom unit will freeze you out.  I have no way personally to check freon levels, nor understand the lingo yet.   I like the units, they are super quiet, no wholes in the roof, etc.  I am looking for a troubleshooting flowchart for these units if anyone has them.
