Mack Truck Parts - A/C, Heater Systems & a Growing Parts Lineup
Mack's reputation is built on durability, and the parts keeping Mack cabs operational need to hold that same standard. Heavy-duty A/C and heater components are TruckAC+'s core strength - and our Mack inventory reflects that: compressors, condensers, evaporators, heater cores, blower motors, receiver driers, expansion valves, fittings, control head assemblies, wiring harnesses, and electrical components, all warehouse-stocked and ready to move.
Beyond climate systems, TruckAC+ is expanding its Mack parts catalog across additional component categories. The vision is straightforward - to be the most reliable heavy-duty parts source for trucks, buses, and off-road equipment, regardless of what system needs attention. We're building towards this goal daily, with the constant addition of new skus in mass.
OEM and aftermarket options are available throughout. Everything ships from our warehouse, every part carries manufacturer warranty backing - and that won't change as the catalog grows.
Mack A/C, Heater Service Parts FAQs
Do you stock A/C and heater parts for older Mack models like the CH and CL series?
Yes. Mack has a long model history, and legacy platforms like the CH, CL, and RD series still see active service. We maintain inventory for older applications alongside current models like the Anthem and Pinnacle. If you're sourcing for an older Mack, contact us with the model and year - availability varies by application but we carry more legacy fitments than most suppliers.
Mack's climate system is known for being robust. Why would I need aftermarket parts?
Even durable systems eventually need service - compressors wear out, heater cores develop leaks, and receiver driers need replacement as part of routine A/C maintenance. Aftermarket parts allow you to maintain the system to the same performance standard at a lower cost per repair. Our aftermarket options are sourced from manufacturers who build specifically for heavy-duty truck applications.
Are Mack Anthem and Pinnacle A/C components interchangeable?
Not always. While some components share fitment across models, others are platform-specific. Control head assemblies, in particular, vary between cab configurations. Always verify by model and year before ordering - or contact us and we'll confirm compatibility directly.
Do you carry the full electrical side of the Mack climate system?
Yes. Beyond the mechanical components, we stock control head assemblies, wiring harnesses, and individual electrical components. Electrical faults are a common cause of climate system problems in Mack trucks, and having the right wiring or control unit available without a long lead time matters.
What warranty coverage comes with Mack parts purchased through TruckAC+?
Every part carries the warranty provided by its manufacturer, facilitated by TruckAC+. Warranty terms vary by component and manufacturer; contact us if you need specifics before ordering.
Can I order Mack parts if I'm a technician at an independent repair shop?
Absolutely. A significant portion of our business comes from independent shops servicing Mack trucks. We don't require a dealer account or fleet affiliation. Order directly, get the part fast, and keep your bay moving.
