How do brand & quality tier change the parts cost?
Brand and tier adjust the parts portion only — never labour. Fisher & Paykel is the New Zealand baseline with the widest, cheapest parts network; value brands (Haier, Simpson) sit below it, and premium and luxury lines (Bosch, Smeg, Asko, Miele) carry pricier, often OEM-restricted components. Pick a tier in the calculator for a class-typical estimate, or a specific New Zealand brand to override it.
| Brand | Parts factor | Basis |
|---|---|---|
| Basic tier parts ×0.875 | ||
| Moisture Master | ×0.9 | Parts ×0.9 (published rates from 2 local repair companies) |
| Haier | ×0.9 | Parts ×0.9 (published rates from 2 local repair companies) |
| Gree | ×0.85 | Parts ×0.85 (The volume NZ value brand: a NZ retailer lists complete Gree heat pumps from NZD 1,156.84 (Kingfisher R32) to NZD 2,524.00 (WEKA 8.5kW). The cheapest complete unit costs under twice a single genuine Mitsubishi inverter board (NZD 635), and even the largest is a complete installed-capable system rather than a single component — clear evidence of a low-cost component set. NZ installer comparisons position Gree as the affordable option with local service agents, supporting a value-tier 0.85 parts factor.) |

That agent's online spares catalogue (systemcontrol.co.nz) is live and carries the Bosch Hot Water parts range, but every part price is gated behind 'Sign In or Apply to view your price' — trade-only, quote-based pricing with no public retail figure — which confirms the closed channel first-hand rather than by inference. One agent, no open retail, no publicly published pricing and no NZ aftermarket found for its continuous-flow gas components means the highest parts premium among the gas brands here, shared with Escea at the 1.20 ceiling. No public NZD Bosch part price was observable (the catalogue figure is login-gated); the factor is channel-structure only.) |

Is it worth repairing a thermostat & controls?
If the repair quote exceeds roughly half the price of a comparable new thermostat & controls — or the unit is well past its typical service life — replacement is often the better value. Localize the repair range above first, then compare.
