Summary


The air handler units provide a versatile replacement for traditional air conditioning systems, seamlessly connecting to pre-existing ductwork. These units are available in 18K, 24K, 36K, 48K, and 60K BTU/h models, offering a quiet and energy-efficient solution due to their variable speed fan motors. The design allows for flexible installation orientations: vertically, horizontally, or downward, catering to diverse architectural requirements.

Designed for compatibility with both single and multi-zone condensers, the 18K and 24K BTU/h models work with multi-zone systems, while the larger 36K to 60K BTU/h models are intended for single-zone applications. These units can connect to any standard 24V wall thermostat and are compatible with standard outdoor models or Hyper Heat upgrades, which ensure reliable heating in ambient temperatures as low as -22°F.

Key features include high static pressure for effective airflow and Quiet Operation technology, enhancing comfort without disrupting the tranquility of the space. This adaptability and efficiency make the air handler units an excellent choice for both residential and commercial settings, providing a high-efficiency cooling and heating solution that integrates smoothly into any environment.
