Service overview
What this service covers
Diagnose supported HVAC building-automation alarms, schedules, sensor inputs, and equipment communication issues. For commercial buildings and managed facilities, 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.
Diagnosis should identify the failed condition and contributing causes before parts or system changes are recommended. The repair scope is based on the equipment found, test results, safe access, parts availability, and whether the system can be returned to stable operation. Completed work should include an operating check and a clear explanation of any remaining risk or follow-up need.
- 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
- Reproduce or document the symptom before disturbing controls or replacing parts
- Confirm the complete operating sequence after the approved repair

I needed 2 new AC units and decided to go with high efficiency heat pumps. I chose Greenflow because of the equipment they offered, and the price (2nd lowest quote and much cheaper than the average of all quote we received). Their technicians were very detail oriented and...

They showed up within an hour of me making the call on a Sunday. They fixed our system and taught us how to replace the fuse in the future. We would definitely call again.
