Does running your air conditioning actually hurt fuel economy in a semi-truck? The answer depends on how and when you use it.
At lower speeds, fuel consumption is driven more by mechanical and rolling resistance, and increased fan usage can impact efficiency. But at highway speeds, aerodynamics become a major factor, making open windows far less efficient than running the AC. Understanding when to use air conditioning versus rolling the windows down can help improve fuel efficiency and keep your truck operating at its best.
