Rooftop and package unit service for working facilities.

Read the building signals

Rooftop units need coordinated mechanical, electrical, airflow, and control checks.

Economizers, belts, motors, coils, drains, controls, and curb or duct connections can all affect performance. Focusing on only the obvious symptom can miss the system issue.

• Poor zone temperature
• Repeated lockouts
• Belt or motor noise
• Economizer problems
• Water intrusion or drain issues

Plan around operations

Access, equipment condition, and operating impact shape the work.

We evaluate the unit in operation, review accessible components and airflow, and account for roof access and building schedules.

• Package and rooftop unit diagnostics
• Economizer and control review
• Belt, motor, coil, and drain checks
• Repair or replacement planning
• Roof-access coordination

Plan the right service

Plan rooftop access and the complete service scope

Package equipment puts several systems in one cabinet, but a rooftop complaint can still begin in the ducts, controls or occupied space. Describe which zones are affected and whether the problem follows a schedule. Record unit identifiers so the office can distinguish similar units serving different areas.

Roof access, safe working arrangements and building permissions should be settled before a visit. If the work coincides with reroofing, clarify disconnection, protection and reinstallation responsibilities. A reroofing job walk is required; do not assume units will be removed from the roof.

Before the visit

Information that helps define the work

• Unit count, model labels and areas served
• Roof access contact and work-hour restrictions
• Coordination with roofing, lifting and electrical contractors

• Rooftop HVAC coordination for reroofing 
• Request California service
