The technician will start the vehicle and turn on the air conditioning system, measuring the actual temperature at the vents at the lowest and highest settings with a thermometer; at the same time, they will connect a manifold pressure gauge to check if the refrigerant pressure in the high and low pressure lines is within the normal range, determining if there is a chronic refrigerant leak.

If there is a minor leak in the lines due to bumps, it is possible that the cooling may not work upon arrival. This is a normal physical loss. The cost of vacuuming, pressure testing, and recharging refrigerant at a local auto repair shop is low and is the buyer's responsibility.

Our standard holding period is 3 business days after the deposit is paid (based on the timestamp of the payment slip). The domestic used car market in China moves very quickly, and if we do not receive the bank message confirming the deposit within the specified time, the system will automatically release the hold, and the vehicle will be re-listed for public sale.
