Product Overview

CBK45UHET Air Handler

Standard performance, high-efficiency, variable-speed air handler compatible with 2025 Compliant Refrigerant

The CBK45UHVT features all-aluminum Quantum™ Coil technology, renowned for its remarkable ability to resist corrosion from environmental contaminants found indoors. Combined with a variable-speed blower motor for consistent airflow and preventing temperature swings.

These -71 models come factory ready for R-454B refrigerant and are equipped with a Refrigerant Detection System (RDS). A built-in sensor will alert the mitigation control to initiate a flush sequence if a refrigerant leak is detected, ensuring safe operation and peace of mind.

Energy Efficiency

  • High-efficiency indoor coil – provides exceptional heat transfer and low air resistance for high-efficiency operation
  • Variable-Speed blower motor produces consistent airflow, preventing temperature swings

Quiet Operation

  • Fully insulated cabinet that reduces sound for quiet operation and helps prevent cabinet sweating in hot and humid environments

Home Comfort

  • Optional electric back up heat to deliver an instant boost of hot air for added comfort

Reliable Performance

  • Antimicrobial drain pan resists growth of mold and mildew which improves indoor air quality and reduces drain line blockage
