Before you hire a heat pump installer in Nelson

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.

The questions below are drawn from 200 customer reviews collected for this page.

What does heat pump installation typically cost in New Zealand?

A single split-system heat pump, supply and installation combined, runs between $2,000 and $4,500 for most living rooms and bedrooms. Multi-head systems covering several rooms range from $5,000 to $12,000 or more.

Ducted systems cost more again, given the additional labour and materials involved. Factors pushing prices up include long pipe runs, high wall mounting, and any electrical switchboard upgrades needed.

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

The electrical connection to mains power is prescribed electrical work under the Electricity Act 1992, so anyone doing it for payment must be registered with the Electrical Workers Registration Board (EWRB) and hold a current annual practising licence, which you can verify on the EWRB public register using the number they give you. Ask for that registration number before you agree to anything.

On refrigerant handling, there is no government occupational licence for heat pump technicians in New Zealand, so what you are looking for is an industry credential issued through the Refrigerant Licence Trust Board, which restricts access to refrigerants among technicians who can demonstrate competence. 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 rather than a general legal one.

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

A legitimate sizing assessment uses a heat load calculation that accounts for your room's floor area, ceiling height, insulation, window size, and local climate, not just a rough guess from square metres alone. As a starting point, budget around 100 to 125 watts of 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 or more. Nelson's climate sits in the middle of the New Zealand range, but an undersized unit will run flat out and still fall short in winter, while an oversized unit short-cycles and handles humidity poorly, so push any installer to show their working before you accept a recommendation.

What are the warning signs of a heat pump installer you shouldn't hire?
  • –An installer who cannot give you an EWRB registration number on request, or becomes evasive when you ask to verify it, is a clear red flag.
  • –Vague or dismissive answers about what refrigerant handling qualification the technician holds suggest the business may be cutting corners on a specialised part of the job.
  • –Charging for a site visit that was advertised as free, as one reviewer reported, signals that terms are not being communicated honestly upfront.
  • –Promising a quote and then going silent, with no follow-up and no explanation, wastes your time and suggests poor business practices that will likely continue post-installation.
  • –A business that books appointments without telling the customer the date or time, and then ignores follow-up calls, points to a serious communication problem at the admin level.
  • –Complaints about workmanship with no offer to remedy the issue, and refusal to provide a fully itemised invoice, are signs you should walk away.

What should you ask before hiring a heat pump installer?
  • –Ask for the installer's Electrical Workers Registration Board (EWRB) registration number and check it on the EWRB public register before any work begins.
  • –Ask what refrigerant handling qualification the technician holds, since it is an industry credential rather than a government licence, and a credible installer will name it clearly.
  • –Ask which brands they are authorised to install, because manufacturer accreditation is tied directly to the warranty on your unit.
  • –If you may be eligible for a Warmer Kiwi Homes subsidy, ask whether the installer is accredited through the Energy Efficiency and Conservation Authority (EECA) approved provider scheme before committing.
  • –Ask how they determine the right unit size for your space, and expect an answer that references your room dimensions, insulation, and local climate rather than a generic figure.
  • –Confirm exactly what the quoted price includes: indoor unit, outdoor unit, all pipework, electrical connection, and a test run, and ask what would trigger additional charges.

How are the top heat pump installers in Nelson chosen?

We build this page from Google Maps results for heat pump installers in Nelson. Each one is scored on its public rating and review record, using the same published method on every page. Businesses outside the area, or whose reviews describe a different line of work, are left out. Every category and city is rechecked on a rolling cycle, about every two to three months. See how we rank for how rankings are made and who is left out. On specialist pages like this one, a business's reviews count in proportion to how many of them are about heat pump installers, so a business mostly reviewed for other work cannot win on review volume alone. See the words we look for.
