Heating Repair & Installation in Nelson

Most jobs start with a diagnostic/service-call fee, then parts and labour on top. A minor fix (thermostat, igniter, capacitor) is modest; a failed heat exchanger, blower motor or control board runs into serious money. The key decision is whether repair cost approaches replacement — past roughly half the price of a new system on an old unit, replace.

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.

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.

Annually, ideally before the cold season — a service checks safety (combustion, flue, gas), cleans components and catches small faults before they become breakdowns. Regular servicing is also commonly required to keep manufacturer warranties valid, so skipping it can cost you a claim later.

Use a properly licensed/registered technician in Nelson — heating work involves gas, combustion and electrical hazards, so registration isn't optional. Get two or three itemized quotes, check they'll pull permits and provide safety certification, and confirm both a parts warranty and a labour warranty in writing.

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.
