Before you hire
Heat pump specialists range from installers of single high-wall units to ducted systems, and most also service existing units. 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 Wellington
Drawn from 424 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 complexity.
Ducted systems, which reviews confirm some Wellington installers offer, sit at the higher end and often take one to two days to install. The Warmer Kiwi Homes programme, administered by EECA (Energy Efficiency and Conservation Authority), can cut costs by up to 80% for eligible low-income homeowners and Community Services Card holders, so check eligibility before accepting any quote at full price.
Factors that push prices up include long pipe runs, high wall mounting, difficult roof or ceiling access, older wiring that needs upgrading, and whether existing pipework needs replacing. One reviewer flagged that a key question across competing quotes was whether replacement of existing 15-year-old pipes was included, which shows how easily like-for-like comparison can break down. Get at least three quotes and confirm each one covers the indoor unit, outdoor unit, all pipework, electrical connection, and a test run before you sign anything.
How do I know if a heat pump installer is qualified and certified? expand_more
The statutory requirement that matters most is electrical: connecting a heat pump to mains power is prescribed electrical work under the Electricity Act 1992, so whoever does that work for payment 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 using the number the installer should give you on request. On refrigerant handling, there is no government occupational licence for refrigeration and air conditioning technicians in New Zealand, as a licensing proposal from MBIE in 2019 remains on hold, so ask instead what industry certification the technician holds, with training and certification run through the Refrigerant Licence Trust Board being the recognised credential in the trade.
Manufacturer accreditation is a separate but practical concern: installing a brand the company is not authorised to fit can void the manufacturer warranty, so ask which brands they are accredited for before you commit. If you are applying for a Warmer Kiwi Homes subsidy through EECA, the installer must also be accredited under that programme specifically, which is an eligibility requirement for the grant rather than a general legal requirement to install heat pumps.
How do I know if the heat pump I'm being sold is the right size for my room? expand_more
A credible installer will carry out a heat load calculation before recommending a unit, factoring in your room's square metres, ceiling height, insulation quality, window area, and Wellington's climate, rather than simply quoting the cheapest or most popular size. As a rough guide, budget around 100 to 125 watts of heating capacity per square metre, meaning a small bedroom needs roughly 2 to 3 kW while an open-plan living area of 50 to 70 square metres needs 5 to 7 kW.
One reviewer noted that good advice on sizing relative to the space being heated was a deciding factor in their purchase, and another reported that switching from gas to a heat pump meant accepting the system was slower to warm the house, a trade-off that should be explained upfront. Undersizing causes the unit to run flat out without reaching target temperatures in winter, while oversizing leads to short cycling, poor humidity control, and money wasted on unnecessary capacity.
What are the warning signs of a heat pump installer you shouldn't hire? expand_more
- –An installer who cannot or will not provide an Electrical Workers Registration Board (EWRB) registration number and current practising licence number is a hard stop: walk away.
- –Vague answers about what refrigerant handling certification the technician holds suggest the company may be cutting corners on a task that requires demonstrated industry competence.
- –Poor upfront explanation of where pipes, conduits, and the outdoor unit will be placed is a red flag: one reviewer discovered only after installation that visible pipes would run through an unplanned wall location, and the company's response was dismissive.
- –Failing to identify structural constraints such as fire walls before the installation day wastes your time and signals the company has not done adequate pre-installation assessment.
- –Installation damage left unacknowledged or followed up only after the customer raises it, with no apology, points to a company that will not back its own workmanship.
- –Unexplained charges added to an invoice after the fact, or a refusal to provide a written quote broken down by labour, materials, and unit cost, are signs of billing practices you do not want to deal with after the job is done.
What should you ask before hiring a heat pump installer? expand_more
- –Ask for the installer's Electrical Workers Registration Board (EWRB) registration number and current practising licence number, then verify both on the EWRB public register before booking.
- –Ask what refrigerant handling qualification the technician holds, since this is an industry credential rather than a government licence, and a credible company will know the answer immediately.
- –Ask which brands they are manufacturer-authorised to install, because fitting a unit outside their authorisation can void the manufacturer warranty.
- –If you are claiming a Warmer Kiwi Homes subsidy, ask whether they are accredited under the EECA (Energy Efficiency and Conservation Authority) programme, as only accredited installers can deliver grant-eligible installations.
- –Ask how they determine the right unit size, and expect a specific answer referencing your room dimensions, insulation, and local climate rather than a guess or a standard package.
- –Ask for a written quote that itemises the indoor unit, outdoor unit, pipework, electrical connection, any required electrical upgrades, and the workmanship warranty period, so you can compare quotes on equal terms.

How are the top heat pump installers in Wellington chosen? expand_more
We build this page from Google Maps results for heat pump installers in Wellington. Each one is scored on its public rating and review record. Businesses outside the area, or whose reviews describe a different line of work, are left out, and a business whose main Google category is a different trade is held back until a person has checked what it does. A business whose website no longer resolves and that has had no Google review for six months is treated as dormant and left off the page until either changes. Every category and city is rechecked on a rolling cycle, about every two to three months. A location with a subscribing business is rechecked every month, and the whole page updates with it. See how we rank for the full method.
