A packaged rooftop unit brings heating, cooling, fans, and controls into one roof-mounted cabinet. Comfort complaints can come from the unit itself, duct distribution, a thermostat, or an operating schedule that no longer fits the building.
Rooftop work also needs access planning. Tell us about roof access, unit locations, model numbers, occupancy, and any building restrictions. Replacement planning may require curb, duct, electrical, fuel, and lifting coordination; these details need review before equipment is ordered.
Signs it is time to call
- A unit trips while other rooftop equipment keeps running

- Airflow and zone-service assessment
- Replacement compatibility and access planning
- Equipment inventory for planned service
Identify the unit before the visit
Label each rooftop unit by the area it serves and keep its model information accessible. This reduces confusion when several similar units share a roof and lets service findings be connected to the correct occupied space.
Common questions
Is roof access part of scheduling?
Yes. Access, building rules, and site safety need to be discussed before the visit. Do not send untrained staff onto a roof to investigate equipment.
Can an existing rooftop curb be reused?
Sometimes, but fit, condition, duct connections, and replacement requirements must be reviewed. Reuse should not be assumed.
