AC & HVAC System Servicing for Electric Vehicles in China
About the Service.
In electric vehicles, air conditioning and HVAC systems are critical not only for driver comfort but also for regulating key components like the battery and motor. At EVS, we will provide complete AC and HVAC servicing tailored for EV platforms—covering everything from climate control diagnostics and refrigerant recharging to compressor and evaporator repairs. Whether your cabin is overheating or your battery thermal system is underperforming, we ensure optimal cooling performance throughout.
Benefits of AC & HVAC System Servicing
Refrigerant Recharging
We refill and balance refrigerant levels to restore cooling efficiency and airflow.
Compressor & Evaporator Repairs
Faulty cooling units are repaired or replaced to resolve AC loss or inconsistent temperature control.
Cabin Climate Optimization
We fix air circulation issues and ensure consistent temperature across all zones.
Battery & Motor Cooling
We will maintain thermal systems that prevent EV battery and motor overheating, especially under Shanghai’s extreme temperatures.
Fan & Ventilation Maintenance
We will service HVAC fans, sensors, and actuators to eliminate noise or low airflow issues.
Leak Detection & Sealing
We locate and seal refrigerant leaks that affect performance and environmental safety.

Frequently Asked Questions.
This could be due to low refrigerant, a faulty compressor, or clogged filters. We run diagnostics to pinpoint and resolve the issue.
Yes. Many EVs use shared thermal systems that cool both the cabin and battery. Poor HVAC performance can increase battery stress.
In hot climates like Shanghai, we recommend a check every 12–18 months or at the first sign of cooling loss or odor.
Yes, once the centre opens. We will use manufacturer-recommended refrigerants and equipment for EV platforms.
This could signal a worn fan motor or failing compressor. We’ll inspect and replace faulty parts as needed.
Why Choose EVS?.
02
Advanced Diagnostics & Tools
The centre is being equipped with EV diagnostic software and insulated tools, so issues are handled safely and accurately.
03
All-in-One Service Center
Repairs, paint, batteries, AC - all under one roof, so a car is not shuttled between three shops.
04
Backed by the EVS Group
The Shanghai centre opens with the tooling, the training and the procedures already running in EVS workshops across the Gulf.

On most electric cars the cabin climate system shares refrigerant circuits and heat exchangers with battery thermal management. A leak or a weak compressor is therefore not only a comfort problem - it is a battery temperature problem, and it should be diagnosed as one system rather than two.
What we expect to see
Where this work usually starts...
Most jobs arrive one of four ways. Knowing which one you are in changes what should happen next, and what it should reasonably cost.
A second opinion on a large quote
Someone has been quoted a figure that does not sound right, usually on a battery or a drive unit. The useful next step is measurement, not another opinion - and if the first quote turns out to be correct, we will say so.
A fault the dealer could not reproduce
Intermittent faults are the ones that get sent away. They are usually a connector, an earth point or a circuit under load, and they are found with a wiring diagram and a meter rather than by changing parts until it stops.
A car being bought or sold
Pre-purchase inspection on a used EV, where the dashboard percentage is an estimate and a state-of-health test is a measurement. Seven-year-old car with a four-year-old battery is a real outcome, and it is worth knowing before the money moves.
A fleet that cannot afford the downtime
Ride-hailing, rental and delivery operators buy predictable turnaround more than they buy any single repair. That is planned capacity, not an emergency, and it should be arranged before it is needed.
How a visit works
What this will look like when we open...
The Shanghai centre has not opened yet, so this is what we are building toward rather than what you can book today.
01
Tell us the symptom
Not the diagnosis. What the car is doing, when it started, and whether anything changed before it - a service, a collision, a software update, a cold week.
02
We measure before we quote
Fault codes say where the alarm went off, not why. Data streams, actuator tests and circuit measurements say why. The quote comes after that, not before.
03
You get the finding in writing
What is wrong, what it will cost, and what can wait. If a cheaper repair will do the job, that is the one we will put in front of you.
04
The work is verified, not just finished
Anything that needed coding gets coded. Anything that needed calibrating gets calibrated and recorded. A job that was not verified is a job that comes back.
