HVAC & Air Conditioning

BYD electric vehicles use high-voltage electric compressors — not belt-driven units — to power the air conditioning and heat pump system, drawing energy directly from the traction battery for efficient cabin climate control and battery thermal management. This category covers electric compressor assemblies, PTC air heaters, blower assemblies, blower speed servos, HVAC units, refrigerant piping, solenoid valves, heat pump waste heat exchangers, and rear air conditioning systems for BYD Atto 3, Dolphin, Sealion 7, and Denza D9. All replacement HVAC components must be rated for the vehicle's high-voltage bus and the correct refrigerant type to ensure safe, efficient operation.
