In this emergency operation mode, you can test the cooling operation of your unit after installation or to complete a maintenance task.

In auto mode, each unit provides air for your home at your desired comfort level. Set your desired temperature, and the HVAC unit will determine how much heat or air conditioning is needed. You can also set this system to a drying function, which will continue to control the space’s air temperature while dehumidifying.

If you desire to keep a room quiet and minimize lighted alerts, you can mute each indoor unit. By muting the system, the buzzer for alerts will not sound and the LED lit display will turn off.

Our previous AC unit was unbearable, but this system has been a game-changer. A huge shoutout to the Chill team, and a special nod to Garrett, who patiently guided me through the selection process. Their customer service was spot on

Thanks for your aid

Helpful staff. I messaged them on their online chat and they got back to me about the different sizes of line sets. Once the unit got here, it went pretty smoothly installing it. We are happy with it.
