Best Heat Pump Installers in New Zealand, Town by Town

A heat pump is a big spend, and the installer matters as much as the unit. Fitted well, it gives you a warm, dry home and lower power bills. Fitted badly, you get cold rooms, noise and callbacks. There are picks for 13 places: Auckland, Christchurch, Dunedin, Hamilton, Lower Hutt, Napier, Nelson, New Plymouth, Palmerston North, Tauranga, Upper Hutt, Wellington and Whangārei.

Each pick explains what the business does, where it is based and why it made the list. Smaller places carry shorter lists, because fewer installers there make the grade, which tells you something about the local market. Treat any list as a starting point. Get two or three written quotes, compare what each covers, and check the electrician is registered with the Electrical Workers Registration Board.

What it takes to make a town's list

Two things get a business onto a list. The first is a Google rating of 4.5 stars or better from at least 10 reviews. The second is a website that shows real heat pump work, not general electrical or plumbing jobs with a heat pump mention tacked on. Ratings alone prove little, since a busy sparky can collect plenty of happy customers without touching a heat pump. The website is where the work itself shows up.

Each pick is written after reading that business's website and its reviews, and covers what the business does, where it is based and why it made the list. Each town's picks come with local detail too: the climate, the housing stock, what to ask an installer in that town and the questions locals raise. Lists are reviewed and updated, and ratings come from Google, so they shift over time. A good rating today is a fair sign, not a permanent badge. Where a town has fewer than 10 picks, it comes down to size, since smaller places have fewer installers who meet the standard.

Questions homeowners ask about choosing a heat pump installer

What should a written quote include?

Ask for the unit make and model, the size in kilowatts, where the indoor and outdoor units will sit, pipework and drain runs, the electrical work, removal of the old unit and the warranty terms. Check whether GST is included and whether the price covers commissioning and a walkthrough of the controls. A quote without a model and size is hard to compare with another.

What size heat pump does my home need?

It depends on the room, not just the floor area. Ceiling height, insulation, glazing, how much sun the room gets and the local climate all change the answer. A good installer will look at the room and work out the heat loss instead of matching the old unit or guessing. Ask how the size was worked out, and be wary of a figure given over the phone.

Does the brand matter more than who installs it?

Both count, but a good unit fitted poorly will underperform. Ask which model is being supplied and why it suits the room, who handles warranty claims locally and how quickly parts can be sourced. Then weigh the quality of the quote and the installer's reviews. A careful installer will explain the reasoning behind a choice rather than push whatever is on the ute.

My town has no picks. Where do I start?

Every installer is in the town pages, where you can filter by the job you need, whether that is a new install, a replacement or a repair. Picks cover the bigger towns and cities. Elsewhere, shortlist two or three, read their reviews and websites yourself, then ask for written quotes.
