Trane, known for its ductless systems for heating and cooling—a definite plus when installing ductwork is impractical or expensive—has taken a northern route with its latest product, the 4MXW38 Ductless Indoor High Wall unit. Designed for cold climates (but also perfectly suitable for warm weather), the residential model features SEER ratings up to 38, EER ratings up to 16.5, and HSPF ratings up to 15. It functions as low as minus 22 degrees, with 100 percent capacity at zero.
The beauty of ductless is its ability to conserve energy and lower your home’s carbon footprint. Air ducts from a central forced air system are less efficient when they travel through unconditioned places like an attic or basement, requiring the heating or cooling system to work harder to achieve a desired temperature. Trane’s models generally do not require ductwork and avoid that environmental setback.
The 4MXW38 uses variable-speed inverter technology, which allows its compressor to continually modulate and adjust to the most-efficient speed. Variable-speed inverters are about 35 percent more efficient than conventional single-speed compressors. Also, all Trane indoor ductless units feature an Auto Clean function with triple air filtration for best air quality.
And, managing the unit’s settings is a…breeze, courtesy of a wireless controller. This makes it possible to mount the system high on a wall or even on the ceiling, reducing clutter, while still enjoying the indoor environment.
