Before you hire

Connecting a heat pump to mains power is prescribed electrical work, so confirm your installer is listed on the Electrical Workers Registration Board register before booking. Refrigerant handling is covered by industry certification rather than a government licence, so ask what qualification the technician holds. Ask installers which brands they are authorised to install, what the manufacturer warranty covers, and what the running cost estimate is for your space.

Before you hire a heat pump installer in Dunedin

Drawn from 186 customer reviews collected for this page. The first answer is what it costs.

What does heat pump installation typically cost in New Zealand? expand_more

A standard single split-system heat pump, supply and installation combined, runs between $2,000 and $4,500 for a single room or living area. Multi-head systems covering several rooms range from $5,000 to $12,000 or more depending on the number of indoor units. Ducted systems cost more again, with some Dunedin reviewers noting the investment pays back through lower power bills and whole-home comfort. The Warmer Kiwi Homes programme, administered by the Energy Efficiency and Conservation Authority (EECA), offers subsidies of up to 80% for eligible low-income homeowners, so check that before accepting any quote.

Full heat pump installation cost guide, with sources

How do I know if a heat pump installer is qualified and certified? expand_more

The most important check is electrical: connecting a heat pump to mains power is prescribed electrical work under the Electricity Act 1992, so the person doing it must be registered with the Electrical Workers Registration Board (EWRB) and hold a current annual practising licence, both of which you can verify on the EWRB public register. Ask the installer for their registration number before you commit, because some Dunedin operators use a separate electrician for this work and you should confirm that person is registered too. On refrigerant handling, there is no government occupational licence for refrigeration and air conditioning technicians in New Zealand, so ask what industry certification the technician holds, as competence credentials are managed through the industry-backed Refrigerant Licence Trust Board rather than a statutory register. Also ask which brands the installer is authorised to fit, because manufacturer accreditation is separate from any registration and directly affects whether your warranty is valid.

How do I know if the heat pump I'm being sold is the right size for my room? expand_more

A legitimate sizing assessment accounts for your room's square meterage, ceiling height, insulation, window area, and Dunedin's colder South Island climate, rather than relying on a rough guess at the time of quoting. As a starting point, expect around 100 to 125 watts of heating capacity per square metre, meaning a 20 to 30 square metre bedroom suits a 3 kW unit while a 50 to 70 square metre open-plan living area needs 5 to 7 kW, sized toward the higher end in Otago. One Dunedin reviewer learned the hard way that being sold an undersized unit meant the heat pump ran constantly and failed to heat the space adequately, with the cost of labour making the upgrade expensive, so push any installer to show their sizing calculation before you sign off on a unit.

What are the warning signs of a heat pump installer you shouldn't hire? expand_more
  • –An installer who cannot or will not provide their Electrical Workers Registration Board registration number before starting work is a red flag, as that registration is legally required for mains connection work.
  • –Vague or evasive answers about what refrigerant handling qualification their technician holds suggest they may not have the industry certification expected by equipment wholesalers.
  • –Poor follow-up after installation, including unanswered calls over multiple days or weeks, has appeared in Dunedin reviews and is a sign of how warranty or fault issues will be handled later.
  • –An installer who recommends a unit size without visiting your home or measuring your rooms is skipping the heat load assessment that proper sizing requires.
  • –Watch for installers who do not disclose upfront that a slightly larger unit costs only a little more in labour, leaving you locked into an underpowered system.
  • –Repeated return visits that fail to diagnose a fault, followed by blaming the house wiring without sending a registered electrician to confirm it, points to inadequate technical follow-through.
What should you ask before hiring a heat pump installer? expand_more
  • –Ask for their Electrical Workers Registration Board registration number and check it on the EWRB public register before agreeing to anything.
  • –Ask what refrigerant handling qualification the technician holds, as this is an industry credential rather than a government licence, and a credible installer will answer without hesitation.
  • –Ask which brands they are authorised to install, because fitting a unit outside the manufacturer's accredited installer network can void the product warranty.
  • –If you are applying for a Warmer Kiwi Homes subsidy through the Energy Efficiency and Conservation Authority (EECA), confirm the installer is accredited under that programme before proceeding.
  • –Ask how they determine the right unit size and request a written heat load calculation, not just a rough kilowatt estimate based on a glance at the room.
  • –Confirm exactly what the quoted price includes: indoor unit, outdoor unit, all pipework, electrical connection, a test run, and any consent or compliance costs, so there are no surprises on the invoice.
