Trane 5TEM6B03AV21S 30,000 BTU 2.5 Ton Variable Speed Multi-Position Air Handler

Trane 5TEM6B03AV21S – 30,000 BTU 2.5 Ton R-454B Convertible Variable-Speed Air Handler

Deliver dependable indoor comfort and efficient airflow management with the Trane 5TEM6B03AV21S, a 2.5-ton convertible variable-speed air handler engineered for residential HVAC systems. As part of Trane’s 5TEM6 series platform, this air handler integrates a variable-speed ECM blower motor, all-aluminum plate-fin indoor coil, and insulated metal cabinet construction designed to provide consistent airflow performance and reliable heating and cooling operation.

Variable-Speed ECM Blower Motor Performance
The 5TEM6B03AV21S utilizes a direct-drive centrifugal blower powered by a variable-speed ECM motor designed to automatically adjust airflow based on system demand. Operating at approximately 1050 RPM , the blower provides nominal airflow of approximately 1,000 CFM , supporting efficient air circulation and improved comfort control across a range of residential HVAC applications.

2.5 Ton Air Handler Capacity Platform
Model nomenclature identifies this unit as a 2.5-ton air handler platform supporting nominal system capacities between 18,000 and 30,000 BTU . The unit operates on 208/230V, 1-phase, 60 Hz electrical service , allowing compatibility with a variety of matched outdoor air conditioning and heat pump systems.

All-Aluminum Plate Fin Indoor Coil
The indoor coil incorporates a durable all-aluminum plate-fin coil design engineered for efficient heat transfer and corrosion resistance. The coil is optimized for R-454B refrigerant systems and uses a thermal expansion valve (TXV) to regulate refrigerant flow and maintain efficient system operation during both heating and cooling cycles.

Convertible Multi-Position Installation Design
The 5TEM6 series air handlers feature a 4-way convertible cabinet design , supporting installation in upflow, downflow, horizontal left, or horizontal right configurations . This flexibility allows the unit to be installed in closets, basements, crawlspaces, attics, or utility rooms depending on the building layout and system requirements.

Durable Insulated Metal Cabinet Construction
The cabinet features heavy-duty metal construction with captured foil-face insulation rated at R-4.2 , helping improve thermal efficiency while reducing cabinet sweating and sound transmission. The cabinet is engineered to maintain 2% or less air leakage , supporting efficient airflow and overall system performance.

Draw-Through Airflow Design with Horizontal Drain Pan
The unit uses a draw-through blower configuration that promotes consistent airflow across the coil and improves heat transfer efficiency. A factory-installed horizontal drain pan and 3/4-inch NPT condensate connection help ensure reliable condensate drainage during cooling operation.

Electric Heat Compatibility for Supplemental Heating
The air handler supports a range of field-installed electric resistance heater kits from the Trane BAYHTR series, providing optional supplemental heating capability when paired with heat pump systems or used in electric heating applications. Heater capacities can be selected to meet specific installation requirements.

Compact Cabinet Dimensions for Flexible Installation
The 5TEM6B03AV21SA features compact cabinet dimensions of approximately 46.8 in. H × 18.5 in. W × 21.1 in. D , making it suitable for installation in tight mechanical spaces while maintaining reliable airflow performance for residential HVAC systems.

Engineered for Reliable Residential HVAC Performance
Ideal for small to medium residential HVAC applications, the Trane 5TEM6B03AV21SA air handler delivers efficient variable-speed airflow control, durable all-aluminum coil construction, and flexible multi-position installation in a compact indoor unit designed to support consistent comfort and long-term reliability.
