Before you hire a heat pump installer in New Plymouth

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 215 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 from $2,000 to $4,500 for a standard room or living area. Multi-head systems covering several rooms range from $5,000 to $12,000 or more depending on the number of indoor units.

Installation complexity, such as long pipe runs or high walls, pushes costs up, as does any electrical upgrade needed to support the new unit. The Warmer Kiwi Homes programme, administered by EECA (Energy Efficiency and Conservation Authority), can cover up to 80% of costs for eligible low-income homeowners, so check eligibility before accepting any quote.

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

The clearest legal check is electrical: connecting a heat pump to mains power is prescribed electrical work, so the person doing 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 and look it up before signing anything.

On refrigerant handling, there is no government occupational licence for refrigeration and air conditioning technicians in New Zealand, so do not be misled by vague claims of official licensing. Instead, ask what industry certification their technician holds, as training and certification in this area is run through the Refrigerant Licence Trust Board, and ask which brands they are manufacturer-authorised to install, since that accreditation directly affects your warranty.

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

A legitimate installer will carry out a heat load calculation factoring in your room's square meterage, ceiling height, insulation, window area, and local climate before recommending a unit size. As a rough guide, plan for 100 to 125 watts of heating capacity per square metre, meaning a small bedroom of around 20 to 30 square metres suits a 3 kW unit, while a 50 to 70 square metre open-plan area needs 5 to 7 kW. Undersizing leaves the unit running constantly without reaching temperature, while oversizing causes short cycling and poor humidity control, so push back on any recommendation that is not backed by a room-specific assessment.

What are the warning signs of a heat pump installer you shouldn't hire?
  • –An installer who cannot or will not provide an Electrical Workers Registration Board registration number before work begins should not be trusted with the electrical connection.
  • –Vague answers about what refrigerant handling certification their technician holds, or dismissing the question entirely, is a red flag on competency.
  • –Recommending a unit brand or model without carrying out any room assessment or heat load calculation suggests the advice is driven by stock availability rather than your needs.
  • –Installation damage left unresolved, such as a drilled joist or incomplete pipe cladding, with no follow-up plan, signals poor accountability after the job is done.
  • –Billing that is unclear or hard to verify line by line, or invoices that arrive without a detailed breakdown, has caused real problems for New Plymouth customers based on review evidence.
  • –Telling a customer to contact the manufacturer directly when the installed unit fails to work properly is a sign the installer will not stand behind their work.

Why over a quarter of heat pump one-star reviews are about what happened after the install

What should you ask before hiring a heat pump installer?
  • –Ask for their Electrical Workers Registration Board registration number and verify it on the EWRB public register before any work begins.
  • –Ask what refrigerant handling certification the technician holds, since this is an industry credential and a sign of genuine competence in the trade.
  • –Confirm which brands they are manufacturer-authorised to install, as unauthorised installation can void the manufacturer warranty on the unit.
  • –If you may be eligible for a Warmer Kiwi Homes subsidy, ask whether they are EECA-accredited under that programme before committing.
  • –Ask how they determine the right unit size, and expect a room-specific assessment rather than a generic recommendation.
  • –Confirm exactly what the quoted price includes: the indoor unit, outdoor unit, all pipework, electrical connection, and a test run should all be itemised so there are no surprises on the final invoice.

How are the top heat pump installers in New Plymouth chosen?

We build this page from Google Maps results for heat pump installers in New Plymouth. 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.
