Life-changing comfort. I was skeptical that a thermostat could impact my well-being, but CoolAir proved me wrong. My home feels like a cozy retreat every day now, and I love knowing I’m saving energy too!

DIY-friendly and intuitive. I’m not an especially techy person, but I installed CoolAir by myself in about 10 minutes. The app walked me through it and now my house is perfectly comfortable all the time. I feel so accomplished – and relieved I didn’t need to hire anyone!

Sets a new standard for smart homes. As a gadget enthusiast, I’ve tried other smart thermostats – CoolAir is on another level. The integration with my phone and Alexa is seamless, and I can even check detailed energy reports. I travel a lot for work, and being able to warm up the house before I get home (or adjust it from 1,000 miles away) gives me such peace of mind.

Comfort for the whole family. We have a two-story home and it used to be impossible to keep everyone happy – the bedrooms were freezing while the downstairs was warm. Not anymore. CoolAir balances our home’s temperature perfectly, and we even added a sensor in the nursery. Now every room feels just right. No more bedtime thermostat battles, just comfortable kids and a happy mom!

Finally, a thermostat with style. CoolAir is gorgeous – it’s the first thermostat I don’t rush to hide when guests come over. The polished design looks like a piece of modern art on my wall. And of course, it works like a dream. It’s maintaining the perfect temperature and even adjusting itself when the afternoon sun hits. Who knew something as simple as a thermostat could add so much luxury to my daily life?

Frequently Asked Questions

No – in most homes you won’t need a C-wire to install CoolAir. The thermostat includes a Universal Power Module that provides its own power supply, so it can work without an existing common wire. We designed it for easy installation, meaning you can likely set it up yourself without special wiring. If your system already has a C-wire, CoolAir will use it, but if not, the included module covers it. The result is a straightforward, hassle-free install for nearly any home.

It works with Amazon Alexa, Google Assistant, and Apple HomeKit, so you can control your thermostat with simple voice commands or include it in your automated routines. No additional hub is needed – just connect CoolAir to your Wi‑Fi, and it syncs up for hands-free convenience.

Each CoolAir also uses dual temperature sensors for ultra-precise climate control, keeping the temperature within about ±0.5°F of your setting to avoid uncomfortable swings.
