Why Choose Green APU?
The Comforts of Home, Away from Home
Whether it be in the heat of summer, or the dark, cold nights of winter, Green APU keeps you comfortable all year long.
Our unit automatically switches between heat, or A/C depending on the outside temperature. You can also control the climate inside your truck with an easy to reach switch, mounted at the lower bunk level. Enjoy your off hours in total comfort!
