How do brand and quality tier change the repair 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 for a class-typical estimate, or a specific New Zealand brand to override it.

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.) |

How much is a service-call fee for oil furnace repair?
Most New Zealand companies charge a call-out / diagnostic fee of $155–$310 NZD, often credited toward the repair if you go ahead. It is separate from the repair totals above. GST (15%) is already included in advertised New Zealand prices, and many sole-trader repairers fall under the NZ$60,000 threshold and add none — so don't add 15% on top.
Is it worth repairing a oil furnace, or should you replace it?
A common rule of thumb: if the repair cost exceeds roughly half the price of a comparable new unit — or the appliance is past ~8 years for a oil furnace — replacement is often the better value. The calculator's localized totals give you the number to weigh against a new-unit quote.
