BYD Dolphin Surf

The climate control system in the BYD Dolphin Surf ensures a comfortable cabin environment while you drive. The system is operated primarily via the 10.1-inch rotatable touchscreen, which includes three-finger gesture control for quick temperature adjustments. This guide outlines how the system operates and what to do if you require professional maintenance.

How the climate system works

Because the Dolphin Surf is a fully electric car with no petrol engine, the air conditioning system uses an electrically driven compressor powered by the high-voltage traction battery. The climate control on all trims is a manual setup operated via the central touchscreen interface. The system not only cools the cabin but also manages the thermal requirements of the 8-in-1 electric powertrain and the Blade Battery.

If the system stops producing cold air or fails to demist the windows, you may need a BYD DOLPHIN SURF air conditioning repair.

Any physical work involving the air-conditioning refrigerant is dangerous work. The refrigerant operates under high pressure, and the compressor is a high-voltage component. Therefore, re-gassing the system or replacing the compressor must be carried out by an authorised BYD dealer or a qualified workshop with the appropriate F-Gas certification. BYD’s own procedure applies to recovering and refilling the refrigerant to ensure the vehicle remains safe.

Warning signs and safe checks

Before booking a professional diagnostic, owners can perform a few safe, user-level checks:

  • Verify that the A/C function is actually turned on via the touchscreen menu.
  • Check if the system is set to recirculate or pull in fresh air.
  • Listen for the sound of the cabin fan blowing at various speeds.
  • Check your owner’s manual to find out how to locate and inspect the cabin air filter, as a severely blocked filter can restrict airflow and mimic an air conditioning fault.

If the fan operates but the air is not chilled, or if you hear hissing noises from the dashboard, confirm with an authorised BYD dealer that an inspection is required.

Remote pre-conditioning

One of the benefits of the Dolphin Surf is the ability to use remote pre-conditioning via the BYD app. This allows you to cool or heat the cabin before you enter the car, using grid power if the car is plugged in, which saves the traction battery range. If the app fails to activate the climate control, ensure the vehicle has sufficient 4G signal and that the traction battery is adequately charged.

Frequently asked questions

Can I re-gas the air conditioning myself?

No. Dealing with air-conditioning refrigerant is dangerous work and legally requires a certified technician to handle the high-pressure gas and avoid environmental contamination.

Why is there a puddle of water under the car?

It is completely normal for the air conditioning system to produce condensation, which drips onto the floor underneath the vehicle, especially on hot days.

How do I use the gesture control for the climate?

The latest UI allows for three-finger gesture control on the 10.1-inch touchscreen. Check your owner’s manual for specific instructions on how to swipe to adjust temperature or fan speed.

Does using the air conditioning reduce the driving range?

Yes, the electric compressor draws power from the Blade Battery. Heavy use of the A/C or heating will lower the achievable WLTP range.
