Inverter and Durable Compressor
More Efficient, Stable Cooling
TOSOT inverter technology has less power loss, lower noise, and saves more energy.
The high-frequency inverter DC compressor cools and heats rooms quickly. This unit won’t wake you up at night by constantly turning the compressor on and off.
Energy Cut by 32% to Save Money
AHRI Certified
The higher the SEER2, the better the energy performance. Rated at 19 SEER2, the Cosmo series split AC is estimated to lower energy costs up to 32% per year, compared to standard 13 SEER2 units.
Work Under Exteme Summer and Winter
Cool at 118°F, Warmth at -13°F
The advanced technology that drives the compressor still achieves stable performance under extreme weather conditions. Built with tough material that resist strong winds and salt corrosions.
R32 AC: Climate-Friendly Cooling
75% less. Zero ozone risk.
Compared to R22 and R410A, R32 has a very low potential impact on the depletion of the ozone layer and global warming.
FRESH, CLEAN AIR
4-in-1 for homes and business
The dehumidification and fan function removes excess moisture from the air. This model is perfect for anyone looking for an all-season AC/heater combo for their home or business.
Zzzz…
The noise level of the indoor unit is only 22 dB, bringing you back to complete silence and keeping the noise of the compressor entirely out of your room. Your comfort will no longer be interrupted by a loud compressor.
