Comfy is only available when your building's HVAC is already on.
If your building shows up as closed or off in the Comfy UI, it means that your building is off. In this case, please follow your usual methods to request after hours air in your facility. If you you believe your building is off during normal building hours, please file a ticket with Comfy Support.
Overall, Comfy cannot take immediate action when the central equipment in your building is off. If a request is made outside of the scheduled operating hours, Comfy still logs your request, but no immediate action can be taken.
