What is a chassis? What is the difference between a fixed chassis and slide-out chassis?
A chassis is the frame that supports the guts of an air conditioner. When the air conditioner is described as a fixed chassis, the chassis does not slide out these air conditioners are for window installation only. Air conditioners with slide-out chassis can be installed into a window or a wall. They are easier to repair because the inside of the machine is easily accessed by sliding out the chassis.
