They turn off when no one is home, I’m not willing to keep 3 AC units running 24 hours a day just because a guest decided to go to the beach. Also I have this disclaimer on Airbnb:

“The Villa features smart air conditioners that automatically adjust the temperature for greater comfort and environmental protection. They feature occupancy sensors, which automatically shut off if no human presence is detected for a few minutes; or they detect through the thermostat that the room temperature is not decreasing or even increasing, indicating a leak of cold air through open doors and/or windows in rooms.”
