Hmmm, I wonder why that would be ?? It seems to me that starting the AC at 95 would take no more power than to start it at 80.

I have run my 13,500 BTU AC with my EF2400is when the outside temperature were in the mid 90s with no problem.

Power output will decrease due to increased ambient temperature. Cold dense air = more power. Hot thin air has less oxygen per charge. This is why turbos/superchargers/NOx are used. More air = bigger charge of O2 = more fuel can be burnt = more power.
