Service overview
What this service covers
Review supported heat-pump and backup-fuel controls, changeover settings, and operating behavior. For Massachusetts homes and residential properties, the useful scope depends on the installed equipment and the conditions present at the property. Control work starts with the intended sequence, schedules, setpoints, sensors, actuators, equipment interfaces, alarms, and observed response of the connected HVAC system.
Service begins by confirming the request, equipment identity, building use, access, operating history, and the result the owner or manager needs. Green Flow then defines the appropriate maintenance, diagnostic, installation, documentation, or replacement path based on the conditions found and the approved scope.
- Document the requested sequence, setpoints, schedule, zones, and current symptoms
- Review sensors, control wiring, communication, and accessible actuators
- Compare commanded operation with actual equipment response
- Record changes and preserve useful before-and-after settings
- Verify the complete control sequence under the available operating conditions
- Confirm the requested outcome and the equipment or areas included in the scope
- Document completed work, observed conditions, and useful next steps
