Base Model Kenworth HVAC Box

These are our Base Model units for the medium-duty model trucks such as T270, T300, & T370. We also have a Base Model for W900, T800, T660, & T660 model trucks.  Our base model could be considered our economical option as it comes with less parts than our standard and premium models. Our base model would be great for an individual who plans to reuse many of their own parts and is ok with using  a little bit more elbow grease. Still have questions? Give us a call at (616) 834-1503.

  • Stainless Steel Shell
  • Upgraded Blower Motor
