HVAC Overview

Your truck's HVAC system heats and cools the cab, so a failed compressor, leaking heater core, or bad control leaves you without heat or A/C on long days. Van Horn Truck Parts carries the full HVAC system cross-referenced to OEM part numbers.

Browse by sub-category — A/C compressors, heater cores, evaporators, blowers, expansion valves, receiver driers, and controls. Match each part by your make, model, and system, and confirm the specific component and its fittings or connector.

Mechanic & Fitment Specs:

  • Sub-categories: A/C compressor, heater core, evaporator, blower, expansion valve, receiver drier, controls
  • Match by: Make/model, system, component fittings/connector
  • Cross-references: OEM
  • Buying tip: Replace the receiver drier/accumulator any time the A/C system is opened
