Commercial HVAC + Property Management HVAC
Scheduled inspections and maintenance that reduce downtime and support equipment life.

Service overview
Scheduled inspections and maintenance that reduce downtime and support equipment life. For commercial buildings and managed facilities, the useful scope depends on the installed equipment and the conditions present at the property. Air-conditioning diagnostics connect the thermostat call, indoor airflow, coils, condensate, electrical starting components, refrigerant operation, and outdoor heat rejection.
Maintenance focuses on condition, cleanliness, controls, drainage, airflow or water flow, electrical connections, wear items, and operating performance appropriate to the equipment. Findings should distinguish completed maintenance from repair needs and create a useful baseline for seasonal readiness and future service.

The appropriate first step depends on the equipment and request. Green Flow may begin with equipment identification and an on-site review before confirming repair, maintenance, installation, or replacement scope.
Access, occupants, tenant impact, operating schedules, and site constraints can be discussed during planning so the approved work can be coordinated appropriately.
