Book a defined visit

Send the system model, last service record and any reported symptoms. Confirm whether the appointment includes both heating and cooling equipment or just one. Ask who approves additional work and whether the quoted visit includes diagnostic time.

Before closing the appointment, obtain the technician’s findings and recommendations. Put “service completed” and “recommended repair approved” in separate fields; an inspection does not mean every defect was corrected.
