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.
Yes – CoolAir seamlessly integrates with all major smart home platforms. 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. This means you can ask Alexa or Siri to adjust the temperature, and CoolAir will respond instantly.

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. This means your living spaces stay evenly comfortable, without the hot or cold spots you might get with less advanced thermostats.
