Pre-Operation, Scheduled and Special Maintenance for Truck Cab Air Conditioners 700519

Many truck cab air conditioning (TCAC) failures are inadvertently caused by service personnel, who fail to provide and maintain an optimum volume and status (contamination) of the system charge. There are some procedures recommended by truck cab air conditioning manufacturers, which can be incorporated by truck owners and operators to increase the effective life of an air conditioning system. If followed, these procedures can cut operating expenses by reducing premature component failure and reducing “down time.” The key to obtaining optimum TCAC performance is to “triple evacuate” the system and “charge by weight.”
