Professional HVAC Wire Harness Manufacturing

OurPCB manufactures HVAC wire harnesses for automotive, commercial, and industrial heating, ventilation, and air conditioning systems. Our climate control cables are engineered for temperature extremes, moisture resistance, and reliable operation in demanding environments.

For automotive applications, we produce A/C compressor clutch harnesses, blower motor cables, and sensor wiring for climate control systems. Our harnesses meet automotive quality standards with OEM-equivalent connectors.

Commercial and industrial HVAC systems require harnesses rated for the full temperature range of heating and cooling operations. We provide high-temperature cables for heating elements and moisture-protected cables for evaporator and condensate areas.

Our control harnesses support thermostats, zone controllers, and building automation connections. From prototypes to production, we deliver HVAC wiring solutions that perform.

Common Questions

HVAC Harness FAQ

HVAC harnesses typically require ratings from -40°C to +125°C to handle both heating and cooling extremes. Cables near heating elements may need higher ratings. We specify materials based on the specific installation location within the HVAC system.

Yes, we produce automotive HVAC harnesses including A/C compressor clutch cables, blower motor connections, temperature sensor wiring, and control panel harnesses. Our automotive harnesses meet OEM quality standards.

Yes, we use moisture-resistant insulation and sealed connectors for HVAC applications where condensation is common. IP-rated connectors and proper wire routing prevent moisture-related failures.

We manufacture shielded cables for refrigerant pressure transducers and other HVAC sensors. Proper shielding protects low-level sensor signals from electrical noise generated by compressors and motors.
