Runtime data of the HVAC unit is received at a control system remote from the HVAC unit. A service message is initiated, by the control system, to a service device associated with the HVAC unit in response to determining that a preventive maintenance visit is warranted based on the runtime data. A hot-cold test for the HVAC unit is activated by the control system in response to receiving the registration message of the preventive maintenance visit from the service device. A validation message is reported in response to validating the preventive maintenance visit based on a result of the hot-cold test for the HVAC unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System for preventive maintenance of HVAC units","description":"There is described a system and method of a building management system for preventive maintenance of an HVAC unit.
