Peterbilt Truck Parts - Heavy-Duty A/C, Heater & More
Peterbilt operators run precise, demanding operations - and a parts supplier needs to match that standard. TruckAC+ built its reputation on heavy-duty A/C expertise, and that shows across our Peterbilt climate system inventory: compressors, blower motors, condensers, evaporators, heater cores, expansion valves, receiver driers, fittings, control head assemblies, and wiring harnesses - all application-confirmed, in stock, and ready to ship.
But A/C is just where we started. TruckAC+ is actively expanding its Peterbilt parts offering across additional truck systems, with the goal of becoming the go-to parts source for heavy-duty operators who want depth, speed, and reliability from one supplier. Both OEM and quality aftermarket options are available across the catalog.
Every in-stock part ships same day from our warehouse, backed by manufacturer warranty coverage from the moment it leaves our dock to the first mile after installation.
Peterbilt Truck Parts FAQs
Do your Peterbilt A/C parts fit both the 379/389 classic models and newer platforms like the 579?
Yes. Our catalog covers a wide range of Peterbilt model years and platforms. The 379 and 389 have distinct system configurations from the aerodynamic 567 and 579 series, and we stock parts specific to each. Always confirm your model year and cab configuration when ordering to make sure you get the right fit.
What's the difference between OEM and aftermarket Peterbilt compressors, and which should I choose?
OEM compressors are manufactured to Peterbilt's exact factory specification. Aftermarket compressors are produced by third-party manufacturers to equivalent performance standards, often at a lower price point. For fleets prioritizing cost-per-repair, aftermarket is a reliable option. For owner-operators who want factory-spec continuity, OEM is the call. Both carry manufacturer warranties.
My Peterbilt's blower motor stopped working. Is that something you stock?
Yes, blower motors are a core part of our inventory. If the motor itself has failed - rather than a wiring or control issue - we carry direct replacements for common Peterbilt applications. If you've already diagnosed the electrical side, we also carry control head assemblies and wiring harnesses if the fault traces back further in the system.
Do you carry Peterbilt expansion valves and receiver driers?
Both are in stock. Expansion valves and receiver driers are frequently replaced together during a system recharge or compressor replacement - we stock them for that reason and can confirm fitment to your specific Peterbilt model.
How do I know the Peterbilt part I'm ordering is the right one for my truck?
Our catalog is organized by make, model, and application. If you have your part number from the old component, that's the fastest route. If not, reach out with your year, make, and model - we'll match the correct part before you order.
Does TruckAC+ handle Peterbilt parts for owner-operators, or just fleet accounts?
Both. We serve independent owner-operators, small fleets, and large fleet maintenance operations. Whether you're ordering a single compressor for your own Pete or sourcing parts across a 40-truck fleet, the process is the same - in-stock inventory, fast shipping, and manufacturer-backed parts.
