Diagnostics first
Good service decisions start with measured symptoms
Controls, refrigerant, electrical, airflow, alarms, and system-response issues should be documented before the repair or replacement path is chosen.
- Controller screen, error code, or thermostat behavior
- System type, symptom timing, and recent service history
- Photos of readings, gauges, panels, leaks, ice, or nameplates if safe
- Whether the issue affects occupied or temperature-sensitive spaces
If occupied spaces, operations, tenants, customers, or critical equipment are affected, call first so the request can be routed with the right urgency.
