Heat Pump Heating for Year-Round Comfort

The 5TWA4036A3 is a split-system heat pump designed to provide both heating and cooling operation. Its single-stage ClimaTuff® scroll compressor and expansion-valve refrigerant control are engineered for dependable heat-pump operation, while compatible indoor equipment provides the air-side portion of the system. Trane specifies AHRI standard rating conditions for high-temperature and low-temperature heating, including a 17°F outdoor-air condition for low-temperature heating ratings.

Commercial Cooling Performance

The 5TWA4036A3 provides nominal 3-ton cooling capacity and uses a single-stage ClimaTuff® scroll compressor with a Spine Fin™ outdoor coil. The outdoor unit is certified under the Air-Source Unitary Air-Conditioner Equipment certification program based on AHRI Standard 210/240, with noise performance rated under AHRI Standard 270. The published A-weighted sound power level for the 5TWA4036A3 is 76 dB(A).

Efficient Heat Pump Operation

The 5TWA4036A3 is part of Trane's current small commercial split heat pump lineup, which offers efficiency options across the product family and uses R-454B refrigerant. The 5TWA4036A3 uses a single-stage compressor, direct-drive outdoor fan, and expansion-valve refrigerant control.

Split System Installation Design

The split-system configuration separates the 5TWA4036A3 outdoor heat pump condenser from the compatible indoor air handler or evaporator coil. Trane identifies compatible split-system component choices as an installation advantage for its small commercial systems. For the 5TWA4036A3, the outdoor unit uses a 3/4-inch gas line and 5/16-inch liquid line, with 25-, 30-, 35-, and 50-foot line-set options identified in the product literature. The outdoor unit is factory charged with the system charge required for the outdoor unit, 10 feet of tested connecting line, and the smallest rated indoor evaporative coil match; final system charge must be verified according to the unit nameplate and applicable charging procedure.

Controls & Comfort

The 5TWA4036A3 uses single-stage heat-pump operation with a direct-drive, single-speed outdoor fan and expansion-valve refrigerant control. Trane also offers an optional anti-short-cycle timer, TAYASCT501A, which prevents compressor recycling until five minutes have elapsed after a satisfied call or power interruption and is identified for applications including commercial installations and long line sets.

Small Commercial Applications

The Trane 5TWA4036A3 is designed as part of Trane's small commercial split-system lineup for applications including small retailers, low-rise buildings, and other small commercial spaces. Trane's commercial product information identifies the small split-system range as covering 1.5 to 5 tons, with heat pump configurations and compatible air-handler choices available for system design flexibility.

Service & Maintenance

The 5TWA4036A3 provides service-oriented accessory options for different installation conditions. Available options include the TAYASCT501A anti-short-cycle timer, BAYISLT101 rubber isolator kit, BAYECMT004 extreme-condition mounting kit, BAYSDEN003 sound enclosure, BAYSEAC001 seacoast kit, BAYLOAM107 low-ambient kit, and TAYSVPANL0044AA service valve panel cover.
