Brick building with fire escapes and air conditioning units

at home

your old window AC unit is loud, bulky, and leaves you burning fossil fuels. there's a better way. sensible is the world's first compact, low-carbon window heat pump. it heats and cools year round, installs in under 5 minutes, and looks nothing like an air conditioner. finally, a single solution for whole-home comfort that you can be proud to use.

sensible benefits

year-round comfort in one sleek unit

stop wrestling with your window AC every spring and hauling in a space heater every fall. sensible heats and cools year-round from a single, compact window unit - no construction, no contractors, and no burning fossil fuels to stay warm or cool. one unit, every season, done.

lower your utility bills

sensible uses high-efficiency heat pump technology to deliver more heating and cooling per dollar than legacy AC units or fossil fuel heating systems. reduce your energy bills month after month while upgrading the comfort of your home.

easy to install on your own

at less than 50 lbs, sensible was designed to be installed by one person in under 5 minutes, without the fear of dropping it out the window. if you've ever installed a window AC unit, you can install sensible. no electrician, no contractor, and no scheduling headaches.

sensible features

electrify heating without high-GWP refrigerants

sensible uses R-290 refrigerant (GWP=3) - the same natural refrigerant used in the world's most efficient appliances - making it the world's first truly low-carbon window heat pump. heat and cool your home all year without the climate impact of conventional air conditioners or heating systems.

ultra compact and whisper quiet

legacy window AC units are noisy, heavy, and dominate your window sill. sensible was engineered from the ground up to be quieter and smaller than anything else on the market. you can sleep through the night, keep your view, and actually enjoy your space while keeping it comfortable.

heating, cooling, dehumidification, and air filtration

sensible replaces four appliances in one sleek package: heating, cooling, dehumidification, and air filtration. ditch the space heater, the dehumidifier, the AC and the air purifier. reclaim your space with one compact unit that lives in your window and handles it all.
