Awesome people and parts. That's all you need to know. I've dealt with customer service multiple times they've went out of their way to help me when I didn't know what I needed. I've bought several replacement lines that have saved me hundreds of dollars. You could rebuild the entire ac system on a kenworth and I'm convinced it would cost half if not less than half of what it would to but factory. Shipping fast too longest I've waited is probably 3 days for anything. I don't even check with the dealer anymore when somethings tore up on my heating or cooling. - Ryan Brown

 

Base Model Kenworth HVAC Box

Base Models

Our base model is the most versatile Kenworth HVAC box we offer, designed to fit a wide range of trucks. It is available in four configurations, including options for heavy-duty models like the W900, T800, T660, and T600, as well as medium-duty models such as the T270, T300, and T370. This economical option includes fewer components than our standard and premium models, making it ideal for those who prefer to reuse existing parts and don’t mind some additional hands-on work. If you have any questions, feel free to call us at (616) 834-1503.
