If you're looking for a back wall AC unit, you're probably familiar with Red Dot. They produce a variety of climate control systems for heavy-duty commercial and military vehicles, including off-road, semi-truck/tractor, commercial vans, and other HD vehicles.

At PartDeal, we carry a full lineup of back-wall AC units from Red Dot, including the most popular models. Let's take a closer look at those units in this post, including what to look for in a backwall solution. 

Red Dot Backwall Mounted Air Conditioners

Interior or back wall-mounted air conditioners are an ideal low-cost alternative to roof-mounted units and work well in a variety of vehicles. Many units are compact, measuring less than 24 inches tall, 20 inches wide, and weighing about 40 pounds. These units provide a similar cooling capacity to many larger, roof-mounted units and provide more mounting flexibility. 

Drawbacks for back wall-mounted air conditioners are that they take up interior space, which may be a problem for smaller cabs or crew compartments. Additionally, the location could affect airflow and output, so the back wall unit may not cool the interior space as effectively as a rooftop unit.
