Looking at 2600RB. Has one 15K air. They show heavy insulation in this unit. Wondering how well they cool when it's really hot? Unit is about 29' box maybe 25'. Thanks in advance.
Well insulted is a relative thing. Still lousy compared to a sticks and bricks. I would expect it to do alright up to the low 100's. After that, it's anybodys guess.
