Gas Recharge This describes installing gas into the A/C system. Usually charging a system means installing all of the gas into the system that it needs. Charging a system should only be done after it has been evacuated and leak-tested, Re-charging suggests that only a portion of the gas has been lost from the system and is being replaced.
Petrol and diesel engines build up carbon deposits inside the cylinders over a period of time. This carbon build up happens for various reasons - from improper burning of fuel, to substandard fuel quality and general build up with age. For engines that have severe carbon build up, one will need to do decarbonisation procedure. This involves opening up the cylinder head, removing the intake and exhaust valves and physically “scrapping” the carbon deposits off the valves, cylinder head and manifolds. The exhaust pipe will also need to be dismantled and cleaned thoroughly using high-pressure water
Nitrogen System Flush and CTC Flush During installation or repair of A/C systems, the system should be flushed with clean special purpose fluids prior to the Evacuation and charge with new Gas. The process removes contamination such as particles of rubber or metal that could foul the system
Leakage Rectification of
All types of pipes
A/C systems sometimes develop small leaks just like car tires do. When a leak develops the A/C can be lost over the course of a few minutes or a day or two. One form of leak testing is done by charging a system with a special purpose. Another form of leak testing is done by a simple pressure test.
