Service overview
What this service covers
Diagnose commercial rooftop equipment that does not provide expected heating. For commercial buildings and managed facilities, the useful scope depends on the installed equipment and the conditions present at the property. Rooftop and packaged equipment combines heating, cooling, airflow, controls, economizer, curb, roof-access, and electrical considerations in a single service scope.
Because the symptom can have more than one cause, diagnosis should follow the operating sequence and evidence instead of assuming a single failed part. 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.
- Follow the heating sequence from thermostat call through controls, heat generation, circulation or airflow, and delivered heat
- Confirm model, serving area, access requirements, and reported operating mode
- Review filters, belts, blowers, coils, drains, controls, and economizer components as applicable
- Inspect visible curb, transition, electrical, and weather-exposure conditions
- Coordinate roof access, safety controls, occupants, and operational windows
- Verify heating, cooling, and airflow operation after approved work
- Reproduce or document the symptom before disturbing controls or replacing parts
- Confirm the complete operating sequence after the approved repair
