Mack HVAC Control

The right HVAC control can mean the difference between a comfortable drive and hours of frustration. The Mack HVAC Control unit makes climate management easy, so drivers can focus on the road rather than fumbling with unreliable temperature settings. Created for heavy-duty trucking applications, this control unit guarantees that heating, ventilation, and air conditioning systems respond accurately to every adjustment. No matter if it’s the height of summer or the dead of winter, a well-functioning HVAC system is essential for maintaining comfort on long hauls. No more second-guessing whether the settings are right—the Mack 20992943 delivers dependable, straightforward climate control.

Mack trucks are built to last, but when the time for repair and maintenance comes it’s strongly recommended to use genuine Mack® components. Designed and manufactured according to strict OEM specifications, Mack parts offer the same engineering and performance as their stock equivalent. This ensures a seamless fit, smooth installation, and reliable operation overall. Mack offers a wide range of genuine parts, including engine, exhaust, transmission, cab, and body parts and accessories. It also offers remanufactured components that offer the same good-as-new quality at a more accessible price range. All genuine Mack parts are tested in both the laboratory and field environments to ensure they meet or exceed industry standards.
