Understanding Air Conditioning System Diagnostic Services at Sunland Tire
Your vehicle’s air conditioning system plays a key role in maintaining a comfortable cabin environment by cooling, purifying, and circulating air. The system operates in a continuous cycle, circulating refrigerant through a sealed system to remove warm air from the cabin. As the refrigerant moves through the system, it changes from a hot gas to a liquid, is cooled, then vaporized back into a gas to absorb heat from the air. At the end of the cycle, cool air is blown into the cabin. This process is powered by the drive belt, which operates the compressor—the core component of the system. The compressor works alongside other parts, including the condenser and evaporator, to maintain proper cooling. If any component fails to function correctly, the entire system may be affected. If your air conditioning isn’t performing as it should, we can diagnose the issue and get your system working properly again.
