Whisper Quiet A/C Change out

[rbrdriver]

I was wondering something for future reference. That would be that if you had to replace an a/c unit on a rig that has whisper quiet a/c system, how is it done? I have replaced them on the regular setups, and also installed an extra one in a rig in the past, but those were the traditional units that you could access from inside. On the rig I have now, there is no access on the inside of the rig to either one. Unless you cut a hole in the ceiling, or take the ceiling down someway. So how the heck does one do it? :

Service is from the roof.

The four scews that are typically on the inside to secure the unit to the roof are accessible from the roof as stated previously.

Well that makes sense. Thanks!
