OEM mild steel housings rarely survive a second life cycle on northern roads.
Factory cab climate enclosures are fabricated from mild steel and mounted where salt, slush, and freeze-thaw cycles hit them hardest. Once corrosion takes hold, the failure cascades fast — and the same unit comes back to the bay for the same repair.
A corrosion-resistant HVAC enclosure built to outlast the conditions that destroyed the original.
Each unit is fabricated from 100% stainless and shipped as a complete, drop-in climate system assembly. Counter teams pull one part number. Service bays install one unit. Buyers stock against a known failure pattern instead of chasing one-off retail.
Two part numbers cover the full compatible Kenworth platform range.
A reference for parts managers and service writers. Fitment confirmation is available from the supply team before any volume order.

A finished assembly — not a parts list to chase across vendors.
Every commercial HVAC assembly leaves the line built, tested, and packaged for the service bay. One SKU pulls one box. One install puts one part on the truck.

Built to support recurring dealer & fleet supply.
Production planning, inventory, and outbound logistics are organized around buyers who need the same part, in the same volume, on the same cadence — quarter after quarter.
Three supply tracks aligned to how commercial buyers actually order.
Pricing and availability are confirmed by the supply team. Custom volumes and multi-location agreements are welcome.

Custom volume agreements are available for dealer groups, fleet maintenance programs, and distributors with predictable replacement demand. Share your monthly run rate and the supply team will structure pricing and dispatch around it.
Specified for the salt belts, gravel routes, and winter rotations that destroy mild steel first.
HVACBoxes.com is built around the regions where corrosion is a daily operating cost: the prairies, the northeast, eastern Canada, the upper Midwest, and any fleet route that sees road salt for half the year. Stainless replacement units exist to break the repeat-failure cycle on those trucks.

What parts managers, technicians, and fleet buyers tell us.
Field feedback from operations that install, stock, or distribute the assembly.
The stainless housing is the right call for our climate. We stopped seeing the same trucks come back for the same HVAC failure, and our service write-ups dropped.
One SKU pulled, one part installed — that alone saves us about 20 minutes per job and removes a step where techs used to grab the wrong component.
Pallet supply hit the dock on time. Packaging held up in transit and the volume pricing actually worked for distribution — not just one-off retail.
Request dealer pricing, fleet program structure, or distributor volume.
Share your operation, expected monthly demand, and preferred dispatch model. The supply team will confirm fitment, recommend the right SKU split between TPL-KHV01 and TPL-KHV03, and shape a program around the way your accounts actually order.
