I hate going into the attic. It must be 150+ up there, Touch a wooden
strut in the truss system and get burnt. But if I have to, I have to.

If you have only one evaporator unit, that is you don't have two systems,
the lower one should drip-drip-drip. That's normal. If the upper one drips,
the lower one is clogged. The upper one would be the emergency condensate
catcher.

There are three common tricks in dealing with a hot attic:

1. Do your work just before dawn. You'll have to use artificial lighting
anyway...

2. Put a lawn sprinkler on the roof.

3. Disconnect one of the ducts and use the a/c to cool the attic. Reconnect
when done.
