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 Auckland

Drawn from 200 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, costs between $2,000 and $4,500 for a single room, with one reviewer citing $1,850 per unit as a competitive all-inclusive price. Multi-head systems covering several rooms range from $5,000 to $12,000 or more depending on the number of indoor units and pipe run complexity. Ducted systems sit at the higher end of that range, and reviewers who had ducted installations confirm costs can push well past $10,000 for a whole-home setup. The quote must include the indoor unit, outdoor unit, all pipework, electrical connection, and a test run before you accept it.

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

The non-negotiable 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 using the number the installer provides. On refrigerant handling, there is no government occupational licence for refrigeration and air conditioning technicians in New Zealand, so do not be misled by anyone claiming one exists. What does exist is an industry certification through the Refrigerant Licence Trust Board, and you should ask what credential the technician holds rather than assuming it is a statutory requirement. If you are applying for a Warmer Kiwi Homes subsidy through the Energy Efficiency and Conservation Authority (EECA), your installer must also be accredited under that programme, which is a separate programme-specific requirement.

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 uses a heat load calculation that accounts for your room's square metres, ceiling height, insulation quality, window area, and local climate, rather than a rough guess or a one-size recommendation. As a starting point, budget around 100 to 125 watts of heating capacity per square metre, meaning a 20 to 30 square metre bedroom suits a 3 kW unit and a 50 to 70 square metre open-plan living area needs 5 to 7 kW. Undersizing causes the unit to run flat-out and still fail to hit target temperatures, while oversizing leads to short cycling and poor humidity control, so push back on any installer who skips a proper site assessment before recommending a unit.

What are the warning signs of a heat pump installer you shouldn't hire? expand_more
  • –Refuses or cannot provide an Electrical Workers Registration Board (EWRB) registration number and current practising licence number when asked directly.
  • –Gives vague or evasive answers when asked what refrigerant handling qualification the technician holds, or claims a government licence exists when none does for this trade in New Zealand.
  • –Provides a quote without visiting the site first, then arrives with a significantly higher price and no explanation for the difference, a pattern seen in multiple reviews.
  • –Leaves hazardous debris such as screws on the site after installation, or causes property damage such as trampled garden beds or leaking drain pipes, and then refuses to take responsibility or respond to follow-up contact.
  • –Fails to show up at agreed times without any communication, or repeatedly reschedules with no apology, both of which are strong predictors of how warranty and after-sales issues will be handled.
  • –Charges for repeat call-outs to fix problems that resulted from their own misdiagnosis or incorrect installation, rather than standing behind their work at no additional cost.
What should you ask before hiring a heat pump installer? expand_more
  • –Ask for their Electrical Workers Registration Board (EWRB) registration number and current practising licence number so you can verify both on the EWRB public register before work starts.
  • –Ask what refrigerant handling qualification the technician holds, since no government occupational licence exists in New Zealand and you want to know their industry credential through the Refrigerant Licence Trust Board.
  • –Ask which brands they are authorised to install, because manufacturer accreditation affects whether the product warranty is valid after installation.
  • –If you are eligible for a Warmer Kiwi Homes subsidy, ask whether they are accredited through the Energy Efficiency and Conservation Authority (EECA) scheme before committing.
  • –Ask how they determine the right unit size and whether they will carry out a site-specific heat load calculation rather than a generic estimate.
  • –Ask for a fully itemised quote that explicitly covers the indoor unit, outdoor unit, all pipework, electrical connection, a commissioning test run, and their workmanship warranty period, so there are no surprise charges after the job is done.
