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 South Auckland
Drawn from 276 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 single split-system heat pump, supply and installation combined, runs between $2,000 and $4,500 for a standard living area or bedroom. Multi-head systems covering several rooms start around $5,000 and can exceed $12,000 depending on the number of units and installation complexity.
One reviewer noted paying $1,850 per unit all-inclusive, which sits at the competitive end of the market for a standard install. If you qualify as a low-income homeowner or hold a Community Services Card, the Warmer Kiwi Homes programme run by EECA (Energy Efficiency and Conservation Authority) can cut your cost by up to 80%.
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 whoever does it must be registered with the Electrical Workers Registration Board (EWRB) and hold a current annual practising licence, both verifiable on the EWRB public register. Ask the installer for their EWRB registration number before work starts, and check it yourself online.
On refrigerant handling, there is no government occupational licence for refrigeration and air conditioning technicians in New Zealand, so treat any claim of a statutory licence with scepticism. Instead ask what industry certification the technician holds, as the Refrigerant Licence Trust Board runs the main competency programme, and also ask which brands the installer is authorised to fit, since manufacturer accreditation directly affects your warranty.
How do I know if the heat pump I'm being sold is the right size for my room? expand_more
A legitimate installer should carry out a heat load calculation that accounts for your room's floor area, ceiling height, insulation, window size, and your location before recommending a unit size. As a rough guide, budget around 100 to 125 watts of capacity per square metre, meaning a 3 kW unit suits a small bedroom and a 5 to 7 kW unit suits a medium open-plan living area, though Auckland's milder climate means you can often size toward the lower end of any range. One reviewer noted that an installer recognised a free upgrade unit was oversized for the room dimensions and flagged it, which is exactly the kind of assessment you should expect from a competent installer.
What are the warning signs of a heat pump installer you shouldn't hire? expand_more
- –An installer who cannot provide an Electrical Workers Registration Board registration number or a current practising licence number before work begins.
- –Vague or evasive answers about what refrigerant handling training their technician holds, since competent operators will name their industry certification without hesitation.
- –No site visit before quoting, because sizing without seeing the room, ceiling height, insulation, and pipe run distance is a red flag for a poor fit.
- –Repeated failure to return calls or provide updates after taking payment, a pattern that appeared across several installers in these reviews and often signals poor after-sales support.
- –Installing a unit incorrectly and then disputing responsibility when faults emerge, including charging repeat call-out fees for problems caused by their own work.
- –Leaving hazardous debris such as screws on site after installation and then refusing to accept accountability when damage results.
What should you ask before hiring a heat pump installer? expand_more
- –What is your Electrical Workers Registration Board registration number, and can I verify your current practising licence on the EWRB public register?
- –What refrigerant handling qualification does the technician who will do the work actually hold, and which body issued it?
- –Are you authorised by the manufacturer to install this brand, and does that accreditation protect the full manufacturer warranty?
- –If I am applying for a Warmer Kiwi Homes subsidy through EECA, are you an accredited installer under that programme?
- –How have you determined the right kilowatt capacity for my room, and can you walk me through the sizing calculation?
- –Does your quote include the indoor unit, outdoor unit, all pipework, electrical connection, and a test run, or are any of those charged separately?

How are the top heat pump installers in South Auckland chosen? expand_more
We build this page from Google Maps results for heat pump installers in South Auckland. 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.
