A/C’s have been rapidly standardized over the last 10 years due to the major enhancement it brings to passenger comfort. However, drivers are only just realising that A/C systems do require regular maintenance.  Vehicle A/C systems will tend to lose refrigerant over time as refrigerant permeates through the physical joins between components.  Over time this will cause deterioration in performance, worse still, if you leave A/Cs operating with low refrigerant levels more serious problems can occur, lubricant circulation may be affected and air or moisture may enter the system.

The consequences could include:
-Poorer fuel economy as the compressor remains engaged to attain lower temperatures
 -Internal corrosion caused by air or moisture reacting with refrigerant
 -Component or system failure
