What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in New Zealand typically run above the national range; smaller towns below it.

- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.

Frequently asked questions
Is an emergency heating call more expensive?
Yes — nights, weekends and holidays carry premium call-out rates, sometimes double the standard fee. If you're safe and warm enough, waiting for regular hours saves money. Treat a gas smell, carbon-monoxide alarm or no-heat in freezing weather as genuine emergencies where the premium is worth paying.
Why is my heating not working?
Common culprits: a tripped thermostat or dead batteries, a clogged filter starving airflow, a pilot/igniter fault, low refrigerant on a heat pump, or a safety lockout from a blocked flue. Change the filter and check the thermostat first; if that doesn't fix it, a technician's diagnostic is the safe next step, especially with any gas smell.
What are red flags when hiring a heating contractor?
No proof of gas/HVAC registration, no diagnostic before quoting a big repair, pressure to replace immediately without explaining why, quotes with no unit model or sizing, cash-only with no invoice or safety certificate, and skipping permits. Anyone who'll work on gas without showing registration is an immediate walk-away.
What's the difference between a furnace, boiler and heat pump?
A furnace blows heated air through ducts; a boiler heats water for radiators or underfloor heating; a heat pump moves heat electrically and both heats and cools. They need different specialists and have very different running costs — heat pumps are efficient but pricier to install, furnaces cheaper up front. Match the technician to your system type.
Should I repair or replace my heating system?
Weigh three things: the system's age, the repair cost, and its efficiency. A repair over about half the cost of a new system, on a unit past its expected life, usually means replace — you're otherwise pouring money into something that will fail again. A newer system with a cheap part failure is almost always worth repairing.
How much does heating repair cost in New Zealand?
A service call runs roughly NZD 100-170, common repairs NZD 200-700, and a new heat-pump install commonly NZD 3,000-7,000 for a single unit. Whole-home ducted systems cost more; eligible homeowners may get a subsidy.
