Trane M5THS1924A11NA Ductless Heat Pump Condenser 24000 Btu 19 Seer R-454B 208-230V Single Phase

Product Description

The Trane M5THS1924A11NA is a single-zone ductless heat pump outdoor condensing unit from the RunTru product line, rated at 24,000 BTU/h with a 19 SEER efficiency rating. It operates on 208-230 volts, single phase, and uses R-454B refrigerant, a lower-global-warming-potential alternative to R-410A. This unit handles both cooling and heating functions, making it a year-round comfort solution. Licensed HVAC technicians install this type of equipment as the outdoor half of a ductless mini-split system, paired with a compatible wall-mounted or ceiling-cassette indoor air handler.

The M5THS1924A11NA is suited for residential and light-commercial single-zone applications where ductwork is not practical or available. Typical installations include room additions, converted garages, sunrooms, server rooms, and multi-family units. The unit is designed for wall-bracket or ground-pad outdoor mounting. At 24,000 BTU/h, it serves spaces typically in the 800 to 1,200 square foot range depending on local heat load conditions. The heating operating temperature range extends down to -13 degrees F, supporting cold-climate performance.

Key Features

• 24,000 BTU/h cooling and heating capacity for single-zone ductless systems
• 19 SEER efficiency rating reduces operating costs compared to lower-efficiency alternatives
• R-454B refrigerant compliance meets current and anticipated low-GWP refrigerant regulations
• 208-230V single-phase power supply fits standard residential and light-commercial electrical service
• Heating operation rated down to -13 degrees F for cold-climate installations
• Inverter-driven compressor technology for variable-capacity operation and efficiency

Compatibility

Designed for use as the outdoor unit in a Trane RunTru single-zone ductless mini-split system, paired with a compatible R-454B indoor air handler. Confirm indoor unit compatibility with Trane product documentation before installation.

Installation Notes

Installation must be performed by an EPA Section 608-certified HVAC technician familiar with R-454B refrigerant handling procedures. Disconnect and lock out all electrical power before servicing either the indoor or outdoor unit. The outdoor unit requires a level mounting surface with adequate clearance on all sides per manufacturer specifications and local mechanical codes. Do not mix refrigerant types or attempt to retrofit this unit with refrigerants other than R-454B.
