Thanks JimL and Stormin Mormon.

Sounds like the AC needs to be taken apart and cleaned.

Even though brand new unit?

From the description it sounds like the "outdoor" portion of the A/C is
essentially in a tunnel a couple feet long which is causing the air to
recirculate and cook the unit instead of dumping heat into the garage.

In order to function and survive in that tunnel it needs to have a
second tunnel i.e. baffle to isolate the intake and exhaust air from the
A/C so they actually make it into the garage instead of circulating in
the tunnel.
