The Standard Tie-in HVAC system uses the vehicle’s existing in-line condenser and compressor for cooling and is equipped with high-efficiency blowers designed to deliver constant airflow. For warmer environments, the Extreme Climate HVAC aftermarket system shares the same components as the London tie-in configuration with the addition of an auxiliary engine-driven compressor, a compressor mount kit and a roof-mounted low-profile condenser.
