TCL's RapidComfort+ dual-hose design eliminates negative pressure, locking in cold air while keeping the heat out to ensure faster, stronger, and more efficient cooling. Enjoy up to 47% energy savings with TCL's advanced AI Inverter technology with whisper-quiet operation, as low as 45 dB, so you can relax or work without interruptions. This 3-in-1 solution combines an air conditioner, fan, and dehumidifier. Despite its compact 14.1x16.5in footprint, it cools spaces up to 450 sq. ft. Control your AC with the TCL mobile app, voice commands via smart home devices, or the included remote. With easy compatibility for windows up to 59", TCL delivers smarter, seamless cooling tailored to your life. Actual coverage may vary based on room size and configuration (ceiling height, number of windows, and other varying conditions) and environmental factors such as number of occupants, home insulation, etc. Up to 47% energy savings is calculated using the Energy Guide's estimated yearly cost of a 10,000 BTU Single Hose Portable AC with single-speed compressor ($119) vs the TCL 10,000 BTU Dual Hose Inverter Portable AC ($63) as of 2024/2025.
