The car ac system is first put through a full diagnosis process which takes about 20 mins to complete. And the customer is presented with a printed report.

You can then present your promotion menu deal - example
  1. your car ac is too warm for comfort, try our standard ac flushing service
  2. your car ac is contaminated, it may soon cause the compressor to fail, consider our complete ac service
  3. your car needs a refrigerant top up, try our refrigerant top up package
  4. the overall performance of the ac components are still good, all you need is a total compressor oil change service
  5. we found a leak in the evaporator, the leak is a small one, would you like us to repair the leak without removing & replace the component
  6. the service fees are reasonable as you do not replace or remove parts, thank you for completing the job within my budget & a short waiting time

The video shows an example of our KoolTec service process
  • The BMW i8 has an electric motor driven compressor
  • The refrigerant type is the latest R1234yf
  • Although its a new car, it does suffer from a small leak and a refrigerant top up is needed every 7 months
  • Special hybrid compressor oil is needed for this job & Leak Gard is injected to stop the small hard to find leaks
  • All the products used are made by top manufacturers in the MAC industry & ensures full compatibility for the i8 AC system

In contrast with the BMW i8, the BMW 528i E39 is a classic 16 year old bimmer.

We take you through the steps to diagnose & flush the car’s AC system.
