"In our rental apartment, it gets unbearably hot in the summer, and the landlord doesn't allow a split system. We tried fans, but they just blew the hot air around. The Coolzy has been amazing so far! It cools the living room in minutes, and I can roll it into the bedroom at night. Plus, it's whisper-quiet—I barely notice it's running." Emma R. – Berlin

Our old duct system costs a lot of money, and we just needed to cool the living room. I saw an ad for this device and thought, why not, it can’t hurt. So far, I’m happy with the purchase. The living room stays cozy without the electricity bill skyrocketing.

We spent a fortune on electricity bills for the central heating just to keep one room warm in winter. Now we only use the one in the living area. It heats up quickly and the bills are much lower. In summer, the cooling is just as effective. We're really very happy with it.

So easy to move. I take it from my office to the bedroom during the day. No fuss at all. I don't have to buy two different heaters or coolers for each room, which saves money and space.

I hated having to get an air conditioner installed. Too expensive and way too complicated. This one was literally just plug in and go. No tools, no handyman. You can easily control it from the couch with the remote. I couldn't be happier.
Frequently Asked Questions
How does the cooling system work?
How does the cooling system work?
Coolzy uses advanced heat exchange technology for fast and efficient cooling. Warm air is drawn in through the vents, passed over cooling coils that absorb the heat, and then blown back into the room as refreshingly cool air. The condensate evaporates inside the unit, so there's no need for a drain hose, water tank, or any complicated setup.
