Outstanding performance, quiet, and energy efficient
03/16/2026I’ve had this ductless air conditioner for about six months now, and it’s the best investment for my 1500 sq.ft. home office/workshop. The heating performance in winter was phenomenal; it maintained a cozy temperature even during sub-zero days. Cooling is equally powerful and silent. The WiFi app is incredibly reliable for scheduling and remote adjustments. The installation kit was complete, and the included lineset was perfect for my setup. Highly recommend for anyone needing a reliable all-season climate solution.
