Trane M5THS1912A11NA Ductless Mini Split Condenser 12000 Btu/h 19 Seer R-454B 208-230V

Product Description

The Trane M5THS1912A11NA is a single-zone ductless mini split outdoor condensing unit rated at 12,000 BTU/h with a 19 SEER efficiency rating. It operates on R-454B refrigerant, a lower-GWP alternative to R-410A, and is designed for single-phase 208-230 volt power supplies. Part of the Runtru 19 Series lineup, this unit is intended for residential ductless cooling and heating applications. Licensed HVAC technicians handle installation, refrigerant connection, and electrical hookup in compliance with local mechanical and electrical codes.

This condensing unit pairs with a compatible Runtru or Trane M5 Series indoor air handler for single-zone ductless applications. It is suited for residential spaces such as individual rooms, additions, sunrooms, garages, and other areas where ducted systems are impractical. The unit handles both cooling and heating functions as part of a mini split heat pump configuration, making it applicable in moderate to cold climates.
