New Plymouth faces straight out into the Tasman, and most of its weather arrives that way. NIWA describes the westerly airstream as the reason Taranaki is one of the windiest regions in the country, and you feel it on the Coastal Walkway on a grey July afternoon when the rain comes in sideways off the sea. Winters here are rarely bitter. They are damp, though, and a house that never quite dries out feels colder than the thermometer says.
That damp is the real job for a heat pump in this town. Older weatherboard villas and bungalows in Westown, Vogeltown and Fitzroy were built long before anyone thought about insulation, while the newer streets out at Bell Block and Highlands Park are tighter and easier to heat. Add salt spray along Strandon, Moturoa and Ōākura, and the mountain sending cold air down to Inglewood, and you can see why local advice matters. These are the installers we'd ring first.
When a New Plymouth home needs an installer
Few people here call about heating on a still, sunny day. It's usually the third wet week in a row that does it. Here's what tends to tip people over.
- Windows stream with condensation every morning and you're wiping black spots off the bedroom ceiling. A heat pump on dry mode helps, and our guide on whether heat pumps dehumidify explains how.
- A gusty westerly makes the outdoor unit rattle, or the lounge loses its warmth every time the wind gets up.
- You live near the sea and the outdoor unit's casing or fins have started to rust or flake.
- The house is warm in the living area but the back bedrooms stay cold and musty, which is the moment to price a multi-room system.
- The unit is old enough that parts are hard to find, or it smells stale when it starts. Our guide to replacing a heat pump helps you decide between a repair and a new one.

1. Premier Heating Ltd
New Plymouth Central, New Plymouth
Aaron's Egmont Street team, best known for hot water heat pumps
Run by Aaron from an office in the Egmont Business Centre, Premier Heating brings heating, gasfitting and plumbing together in one Taranaki business. That mix shows in what it fits: underfloor and radiator heating, central heating, smart thermostats with zoning and wi-fi options, and gas appliances. It is also the Escea service agent for Taranaki, which covers Infinity gas hot water units and gas fires.
Hot water heat pumps are the specialty. The team works out how much hot water a household actually uses before recommending a size, then handles the install, repairs, maintenance and the swap from an old cylinder. Panasonic and Ritter are among the brands it works with, and it can guide you through applications for energy efficiency incentives. Light commercial jobs are taken on as well as homes.
Why they made the list
If your hot water cylinder is near the end of its life, this is a team that thinks about water heating first rather than as an add-on. Heat pump installs, radiators and underfloor heating are what customers bring up most, along with hot water and boiler repairs. The gas and plumbing skills mean one crew can handle a mixed system.

2. Summit Refrigeration
New Plymouth Central, New Plymouth
A family refrigeration firm on Courtenay Street that works on farms as well as homes
Summit Refrigeration is a family owned and operated business with more than 80 years of combined experience across its team. From its base on Courtenay Street it installs, repairs and replaces heat pumps for homes and offices, and designs and maintains systems for small to medium-sized businesses.

Refrigeration is the other half of the business. It builds and services freezers and cool rooms for light commercial clients, and on dairy farms it handles milk vat cooling, heat recovery and water chiller systems. Quotes are free and come with no obligation.
Why they made the list
Heat pump installs make up the bulk of what customers talk about, and the comments keep returning to a smooth process, quick installations, tidiness and polite staff. Mitsubishi units and ducted installs both come up, as do quiet running and honest advice. A firm that also keeps farm and shop refrigeration going knows its way around refrigerant work.

4. Re:Lume Electrical
New Plymouth Central, New Plymouth
Women-owned electricians on Leach Street who pair heat pumps with solar
Family owned and run, Re:Lume Electrical works from Leach Street and takes on new builds, renovations, residential jobs and commercial work across Taranaki. It is a women-owned business, and its team likes to work alongside architects and builders rather than arrive at the end of a project.
Renewable energy is a big part of the work. The team designs, installs and maintains solar and battery systems for owners who want more control over their power use, and heat pumps sit next to that as a service of their own. If you're building, renovating or adding solar, the heat pump wiring can be planned at the same time instead of squeezed in later.
Why they made the list
Communication is the thing customers mention more than anything else, well ahead of the rest. After that come workmanship, promptness, efficiency and a responsive team, with heat pump installs and EV charging among the jobs people describe. Every review it has is five stars, and working closely with builders suits anyone in the middle of a renovation.

5. New Plymouth Home Heat Pumps
New Plymouth Wide
Coastal siting and a rinse routine for homes from Ōākura to Waitara
Lingering moisture and salt air shape how New Plymouth Home Heat Pumps goes about a job. Near the coast it fits outdoor units on corrosion-resistant brackets and mounts, and it recommends rinsing the outdoor coil now and then to help it last. The service area runs from Ōākura and the coast through Bell Block and Waitara to Inglewood and the inland towns under the mountain.
Every common type is available, from a single wall unit or floor console to cassettes, multi-split and ducted setups, each sized for the room rather than the floor plan. Renovated bungalows and the open-plan newer builds at Bell Block are typical jobs. An install includes insulated pipework, graded drainage so condensate clears, the electrical connection and certification, and commissioning. It services and repairs only the systems it fits, and quotes are free and fixed.
Why they made the list
Without any customer reviews, judge it on its approach. It plans for salt and damp from the start, offers every common system type, and keeps the install and the later servicing with the same people. Each unit carries the manufacturer's warranty, and the fixed quote means you know where you stand.

Waiwhakaiho, New Plymouth
Waiwhakaiho's Panasonic specialists, from one high wall to ducted
Based on Bridle Street in Waiwhakaiho, HeatCool Taranaki is a locally owned heat pump and air conditioning company working with homes and commercial premises around the region. It sells Panasonic exclusively and has earned Elite dealer status with the brand, and the Panasonic units it supplies come with a five-year warranty.

Why they made the list

Having ventilation and hot water from the same people makes it easy to tackle damp and heating together.

10. Tengo Electrical

Choosing the right installer for a Taranaki house
Ask first about where the outdoor unit will go. In a town this windy, a spot sheltered from the full force of a westerly helps the unit run steadily and keeps it quieter. Close to the sea, ask what brackets and coatings the installer uses and how often you should rinse the coil. Our guide to heat pump noise covers placement too.
Next, think about damp as much as warmth. A house in Westown or Vogeltown that stays cool and clammy all winter may need a unit that runs low and steady through the day, and possibly some ventilation as well. Ask how the installer sized the unit for your rooms, and read what size heat pump you need so you can check the answer.
If the house has separate rooms off a hallway, compare a single high wall unit with a ducted system or a multi-room setup. The ducted or high wall guide lays out the trade-offs.
Line up quotes side by side: the brand and model, the indoor and outdoor positions, the pipe run, and what the workmanship guarantee covers on top of the manufacturer's warranty. Then ask who will service it. Salt and damp both make regular servicing worthwhile; see our heat pump servicing guide for what should be checked. Last of all, make sure the people wiring the unit and handling the refrigerant hold the right tickets; who can install a heat pump sets out the qualifications to ask about.
