What changes a Rinnai repair bill
- Brand tier — Large Australian ducted-heater, gas space-heater and evaporative-cooler installed base with an unusually deep openly-traded parts catalogue. Placed at the mainstream baseline on genuine HVAC (space-conditioning) parts ONLY: A20 A-Series evaporative-cooler N-E6+B main control box A$502.00, A20 6-blade fan A$177.00, A20 fan capacitor 8uF A$35.00 and A20 solenoid A$98.00, plus a gas-heater thermocouple/overheat-switch pilot flame sensor A$174.00 — all in line with Bonaire's A$52.00-A$424.00 gas-control band. Water-heating parts (tank thermostats, water filters) are excluded from the basket per this file's scope rule, so Rinnai's large hot-water catalogue is not used as an HVAC price anchor
- Parts vs labour — the brand and tier shift the parts price; labour tracks your area's wage index, not the brand.
- The specific fault — a sensor, seal, or valve is far cheaper than a compressor, motor, or control board.
- DIY vs professional — Some Rinnai faults (filters, seals, hoses) are DIY-feasible for confident owners; sealed-system and control-board work is a professional job.
