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 South Auckland

Drawn from 199 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

Supply and installation of a standard single split-system heat pump for a small bedroom or office runs between $2,000 and $3,000. A medium-sized living area unit with more capacity sits in the $3,000 to $4,500 range. Multi-head or multi-room systems start around $5,000 and can reach $12,000 or more depending on the number of indoor units. One reviewer cited $1,850 per unit all-inclusive, which sits at the competitive end and reflects that prices vary meaningfully between installers, so getting at least three quotes is worthwhile.

Full heat pump installation cost guide, with sources

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

The clearest legal 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 at ewrb.govt.nz. Ask the installer for their EWRB registration number before you book, and check it yourself rather than taking their word for it. On refrigerant handling, there is no government occupational licence for heat pump technicians in New Zealand, so what you are looking for instead is an industry credential, typically issued through the Refrigerant Licence Trust Board, which confirms the technician has demonstrated competence to handle compressed refrigerant gases. Also ask which brands the installer is factory-authorised to fit, because installing through an unauthorised trader can void the manufacturer warranty regardless of how competent the work appears.

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 looks at your room's square meterage, ceiling height, insulation, window area, and local climate before a unit is recommended, not just a rough guess based on room size alone. As a starting point, expect around 100 to 125 watts of heating capacity per square metre, meaning a small bedroom of 20 to 30 square metres suits a 3 kW unit, while an open-plan living area of 50 to 70 square metres needs 5 to 7 kW or more. One reviewer flagged that a well-intentioned free upgrade to a higher-capacity unit actually caused problems because the units were overpowered for the rooms, which shows that oversizing is a real issue, not just undersizing.

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 (EWRB) registration number on request, or who gets defensive when you ask, is a serious red flag.
  • Vague or evasive answers about what refrigerant handling qualification the technician holds suggest the person doing the work may lack recognised industry competence.
  • Reviewers reported installers placing outdoor units in positions that blocked gates or access paths, with no prior discussion, which points to poor site planning and a lack of care about the outcome.
  • Multiple reviews described repair visits that failed to fix the problem, followed by no communication and no follow-up, which is a sign the business does not back its own work.
  • An unboxed unit supplied on arrival, or a unit substituted from the one in the contract without prior notice, are signs of a supplier cutting corners in ways that could affect warranty coverage.
  • Charging for repeat call-outs caused by the installer's own diagnostic errors, rather than absorbing that cost, is a sign you will be left out of pocket when things go wrong.
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 verify it yourself on the EWRB public register before agreeing to anything.
  • Ask what refrigerant handling qualification the technician holds, since there is no government licence but a recognised industry credential through the Refrigerant Licence Trust Board is the standard to look for.
  • Ask which brands they are factory-authorised to install, because using an unauthorised installer can void the manufacturer warranty on the unit itself.
  • If you are applying for a Warmer Kiwi Homes subsidy through EECA (Energy Efficiency and Conservation Authority), confirm the installer is accredited under that programme before proceeding, as the grant requires it.
  • Ask how they determine the right unit size for your room, and expect a genuine answer that references your room dimensions, insulation, and ceiling height rather than a ballpark figure.
  • Ask for a fully itemised quote that spells out what is included: the indoor unit, outdoor unit, pipework, electrical connection, brackets, and a test run, so there are no surprises on invoice day.
