Using inferior refrigerants or lubricants can also reduce efficiency and damage the system.

Impact: Increased downtime, higher maintenance costs, and potential safety risks from cabin overheating.

Inadequate Testing and Certification

Some sourced AC units lack proper testing for real-world trucking conditions—such as high ambient temperatures, prolonged idling, and road vibration. Units may not meet SAE or OEM performance standards (e.g., SAE J1578), leading to poor cooling performance during hot weather or long hauls.

Impact: Non-compliance with fleet specifications and customer dissatisfaction due to unreliable climate control.

Counterfeit or Reverse-Engineered Products

A significant risk in the aftermarket is the proliferation of counterfeit or cloned AC systems that mimic OEM designs (e.g., Thermo King, Carrier Transicold). These products often infringe on patents, trademarks, or trade secrets, and lack the engineering integrity of genuine units.

Impact: Legal exposure from IP infringement, voided warranties, and compromised system reliability.

Lack of Traceability and Documentation

Suppliers may fail to provide full documentation such as material certifications, test reports, or bills of materials. This lack of traceability makes it difficult to verify compliance with quality standards or investigate failures.

Impact: Difficulty in warranty claims, compliance audits, or recalls; increased liability for fleet operators or OEMs.

Insufficient IP Due Diligence

Buyers often neglect to verify whether the AC system design, software, or key components are protected by third-party IP rights. Using a unit that incorporates patented technology without a license can result in infringement lawsuits or supply chain disruptions.

Impact: Legal penalties, forced redesigns, or injunctions halting use or resale of the product.

Overlooking Software and Control System IP

Modern truck AC systems rely on electronic controls and proprietary software for diagnostics, efficiency, and integration with vehicle telematics. Unauthorized use or replication of such software can violate copyright or licensing agreements.

Impact: Cybersecurity vulnerabilities, non-compliant emissions or fuel efficiency reporting, and legal action from IP holders.

By proactively addressing these quality and IP-related pitfalls—through supplier vetting, independent testing, and legal review—buyers can ensure reliable performance and avoid costly legal and operational setbacks when sourcing AC systems for semi trucks.
