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.

Before export, we perform a standard external wash and interior vacuuming to meet basic hygiene inspection requirements by customs. However, we do not engage in deceptive "refurbishments" (such as repainting large areas with cheap paint or using low-quality interior refurbishing agents) to preserve the vehicle's true physical condition for buyer assessment.

The lifespan of rubber sealing strips for frameless doors is usually only 4-5 years. We carefully press the sealing strip at the edge of the roof to check for loss of elasticity and use a high-pressure water gun to wash the seams of the windows to check for direct water leakage due to aging.
