Cabs/Heating and Air Conditioning

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of heating and air conditioning assemblies and core internal climate control components to support diverse excavation, earthmoving, material handling, and roadbuilding requirements:
• Machine & Climate System Compatibility: Engineered for a broad range of Caterpillar equipment—including medium/large excavators (e.g., CAT 320, 336, 349), wheel loaders (e.g., CAT 950, 966, 980), and track-type tractors (e.g., CAT D6, D8, D9)—our parts ensure exact physical and functional alignment with original factory A/C compressors, heater cores, control panels, and ductwork to guarantee a perfect match.
• Complete Heating & A/C Systems & Components: 1. Assemblies & Housings: Complete evaporator box assemblies, heater core assemblies, A/C compressors, and condensers; 2. Electrical & Control Components: Digital/mechanical control panels, blower motors, blower resistor speed controls, and temperature/pressure sensors; 3. Heat Exchange & Plumbing: High-pressure A/C hoses, heater water lines, expansion valves, receiver driers, and high-seal O-ring kits; 4. Air Filtration: High-efficiency cabin air filters, fresh air elements, and activated carbon dust-proof/deodorizing filter screens.
• OEM & Heavy-Duty Aftermarket: We offer genuine Caterpillar heating and A/C components alongside rigorously tested aftermarket alternatives featuring corrosion-resistant reinforced cooling fins and long-life bearings, delivering equivalent cooling/heating performance and extended durability while providing flexible, cost-effective options for global clients.

Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global machinery climate control component procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international buyers.
• Seasonal and Ready-to-Ship Inventory: We maintain large-volume stock of high-demand air conditioning compressors, blower motors, heater cores, and air filters specifically tailored for peak summer high-temperature and winter freezing maintenance periods. We also guarantee direct dispatch upon order confirmation to minimize unplanned equipment downtime caused by climate control system failures.
• Precision Packaging and Protection: We implement rigorous industrial packaging standards specifically designed for aluminum condenser and heater core radiator fins, precision electronic control panels, and compressors utilizing moisture-proof and shock-resistant industrial bubble wrap, custom corrugated cartons, and wooden pallets to ensure parts withstand long-distance ocean or air transport without impact damage.
• Refrigerant and Chemical Compliance Support: We supply regulatory documentation complying with international environmental safety and customs compliance requirements for relevant climate control components, ensuring secure and smooth cross-border transit.

Engineering Solutions & Technical Support
Our technical framework focuses on resolving field-level operational challenges to eliminate equipment downtime, moving beyond simple parts distribution to deliver comprehensive engineering and service capabilities.
• Application-Specific Climate Solutions: We address common field issues in extreme working environments, such as sub-zero permafrost regions near the Arctic Circle, extreme desert heat in the Middle East, and high-dust mining operations, where heater cores experience frequent scaling and clogging, condensers suffer from poor thermal dissipation leading to high-pressure protection shutdowns, and air conditioning lines develop leaks from intense vibration. We also provide professional engineering upgrades, including thickened anti-freeze heater cores, heavy-duty dust-resistant condenser guard screens, and vibration-resistant high-pressure temperature-resistant air conditioning hoses.
• HVAC System Troubleshooting and Diagnostics: We address common user complaints regarding air conditioning and heating failures, such as compressor magnetic clutch non-engagement, refrigerant leak localization, and blower motor noise or zero air output, and we provide professional diagnostic guidelines, including nitrogen pressure testing and fluorescent leak detection, to pinpoint hidden line cracks, alongside system flushing mandates for burnt compressor replacements that require professional cleaning of the entire HVAC circulation loop and mandatory receiver-drier replacement to prevent secondary contamination from residual debris.
• Expert Technical Support and Safety Guidelines: We provide professional technical documentation covering air system evacuation standards, polyalkylene glycol compressor lubricating oil quantitative addition specifications, refrigerant R134a charge weight guidelines, and heating system air bleeding procedures to ensure efficient and stable operation of equipment climate control systems.
