Trane M5THS1936A11NA Runtru Ductless Heat Pump Condenser 36000 Btu 19 Seer R-454B 208-230V

Product Description

The Trane M5THS1936A11NA is a RunTru-series ductless heat pump outdoor condensing unit rated at 36,000 BTU/h with a 19 SEER efficiency rating. It operates on R-454B refrigerant, a lower-GWP A2L refrigerant now standard in newer residential and light-commercial mini-split systems. The unit runs on 208-230 volts, single phase, and functions as both a cooling condenser and a heat pump for year-round operation. Licensed HVAC technicians install this unit as part of a single-zone ductless split system, pairing it with a compatible indoor air handler. It is suited for residential and light-commercial applications where ducted distribution is not practical or cost-effective.

The M5THS1936A11NA is designed for single-zone ductless installations in residential and light-commercial settings. Typical applications include room additions, garage conversions, server rooms, and supplemental zoning in existing structures. The unit pairs with a matched RunTru indoor wall-mount or ceiling-cassette air handler to form a complete ductless split system. Its heat pump capability makes it appropriate for climates with moderate heating demand, with a published heating operating range down to -13 degrees F, allowing continued operation in cold-weather conditions without auxiliary heat in many applications.

Key Features

• 36,000 BTU/h cooling and heating capacity for large single zones
• 19 SEER efficiency rating for competitive energy performance
• R-454B refrigerant — lower global-warming-potential A2L refrigerant compliant with current regulations
• Heat pump operation with a heating operating range down to -13 degrees F
• 208-230V single-phase power supply for standard residential and light-commercial electrical service
• Outdoor condensing unit designed for single-zone ductless split system configurations

Compatibility

Designed for use as the outdoor condensing unit in a RunTru single-zone ductless split system. Requires a matched RunTru indoor air handler rated for R-454B refrigerant. Verify indoor unit compatibility against Trane RunTru match-up tables before installation.

Installation Notes

Installation must be performed by an EPA Section 608-certified HVAC technician familiar with A2L refrigerant handling procedures, as R-454B carries a mild flammability classification requiring specific precautions during brazing, evacuation, and charging. Disconnect and lock out all electrical power before servicing the unit. Follow local mechanical codes and the manufacturer installation manual for refrigerant line sizing, outdoor unit placement, and clearance requirements. Do not mix refrigerant types or reuse line sets from systems previously charged with R-410A without proper flushing and inspection.
