When it comes to your tractor, truck, or construction vehicle, only the most efficient and best-quality AC units will do.

Red Dot Corporation has provided premium mobile AC units for commercial applications since 1965. That’s why PartDeal is proud to stock a full range of their AC units. This post covers the benefits of Red Dot backwall AC units and the ten most popular Red Dot backwall models we offer.

What Makes A Headliner AC Unit A Great Choice?

Headliner AC units (also known as overhead ACs) are popular thanks to their efficiency and compact design. The AC unit is mounted inside the cabin, protecting it from the elements and accidental damage.

If you don’t have cabin space or prefer a roof-mounted AC unit, read about some of our most popular Red Dot Rooftop AC offerings here. If you aren’t quite sure which AC unit best suits your needs, then our blog on the pros and cons of both types is a worthwhile read. Red Dot headliner AC units:

• Tend to be more cost-effective than Rooftop-mounted AC units
• Are suitable for use in a broad range of commercial vehicles
• Have a compact design without reducing performance
• Are less likely to be damaged than external AC units
