The climate control system in this fully electric vehicle manages both cabin comfort and the temperature of the traction battery. This page outlines the components of the heating and cooling network and what is involved in a BYD DOLPHIN air conditioning repair.
Because the system is integrated with the high-voltage Blade Battery, maintenance goes beyond simply recharging refrigerant gas. High-voltage components must not be opened by owners. Confirm with an authorised BYD dealer for any diagnostic work. Check your owner’s manual for everyday operating instructions.

BYD DOLPHIN air conditioning repair
A BYD DOLPHIN air conditioning repair may be necessary if the cabin fails to cool down on a hot day or if the windows take too long to demist in winter. The car relies on an electric compressor rather than a belt-driven one found on a petrol engine.
The refrigerant circuit is complex because it also provides direct battery cooling and heating. Leaks or compressor failures must be diagnosed using specialist electronic tools. BYD’s own procedure applies to all air conditioning maintenance. Confirm with an authorised BYD service centre to ensure the correct amount and type of refrigerant is used, as incorrect fluids can damage the electrical system.
Heat pump system
The Comfort and Design trims feature a highly efficient heat pump. This unit captures waste heat from the electric motor and the environment to warm the cabin and the battery. It provides better winter thermal efficiency than a traditional resistive heater, preserving the vehicle’s driving range. Repairs to the heat pump must be handled by trained technicians.
PM2.5 cabin filter
The climate control system includes a PM2.5 filter to purify the air entering the cabin. This component traps dust, pollen, and pollutants. It requires periodic replacement to maintain airflow and air quality. Check your owner’s manual to find the location of the filter access panel and see if it is a task you are comfortable performing.
Warning signs and owner checks
Drivers should monitor the performance of the climate control through the rotatable touchscreen interface.
What owners can safely check:
- Verify that the air vents are open and unblocked.
- Check the cabin filter if airflow seems restricted.
- Look for error messages on the infotainment display.
Do not attempt to open any refrigerant lines. Confirm with an authorised BYD dealer if the system stops producing cold or hot air.
