Question about portable air conditioners and exhaust tube lengths – Page 2 – Computer Setup and System Configuration Forum

I had to get one for my bedroom this year. My house doesn’t have any sash type windows. They are all side slide or crank types. The bedroom has 6’ tall crank windows only. Impossible to install a standard window unit. So the portable was the answer. I had to build a special mounting adapter for the hoses.

They are quite noisy. Much noisier than window units. This one has two hoses. The exhaust hose does get quite hot. Even a short 1.5m length. The unit didn’t need to be drained all summer. It is designed to shut down if the drip pan gets too full.
The latest batch of these things have become quite efficient.

The unit I have is a 7000 BTU unit that handles my 500sq ft bedroom quite nicely. The unit has fan, cool, dehumidifier and heater modes…and a neat remote. Once it reaches the target temp you set, it will shut off. When the temp drops 2 degrees, it fires up again. Pretty efficient, actually. Takes about 40 minutes to drop the room from 85 degrees to 68.
