Can Clean Air Come Without the Noise, Clutter, or Hassle?

A New Take on the Old Window Unit

Most air conditioners are bulky and noisy and block your window. Gradient was designed to change that. It’s a sleek heating and cooling system that hangs below your window instead of inside it, so you still get sunlight and fresh air without giving up comfort.

The unit pulls air in from the outside, warms or cools it as needed, and gently pushes it into your room without the loud hum or heavy cold blast you’re used to. There’s no need to modify your walls or hire an installer. It’s designed to be set up easily by the user, making it more accessible for apartment dwellers and city homes.

Comfort That Doesn’t Take Over Your Room

Gradient isn’t just about looks. Its compact shape and whisper-quiet operation make it practical for small spaces, shared apartments, or anyone who wants comfort without disruption. It runs on a heat pump system, which means it can cool your home in the summer and warm it in the winter, all while using less energy than traditional units. And because it doesn’t block your view or need permanent installation, it’s a better fit for people who move often or rent their space.

Cooler Homes, Cleaner Future

Heating and cooling account for a huge portion of household energy use and many older systems rely on refrigerants that harm the environment. Gradient’s system was built to work more efficiently and use cleaner technology that reduces climate impact. It's also designed with real-world living in mind especially for people in places where installing central heating or cooling just isn’t realistic. As cities grow and more people live in older buildings or rental spaces, there's a need for solutions that work without major renovations. Gradient offers a way to stay comfortable without relying on the same old systems that no longer fit how many of us live.
