TopChoice recommendations are editorially curated by our New Zealand team. Rather than listing every business that pays to appear, we research each local market and shortlist only the heat pump installers who consistently stand out.
We don't host our own reviews. Instead, we draw on public reputation signals from Google and other platforms, alongside the wider research that goes into each list. Every heat pump installer is assessed using a consistent framework that considers factors such as:
Every Top 5 list is reviewed periodically and can change over time as businesses grow, improve, or fall short — so the recommendations stay current and worth trusting.
Before you commit, it pays to ask a few key questions.
A unit that's too small will struggle; too big can short-cycle and feel uneven.
Placement affects noise, airflow, drainage and long-term performance.
For whole-home comfort ducted can be ideal — but it needs proper design.
Confirm electrical, pipe runs, brackets, drainage and any roof or ceiling work.
Ask who you call for servicing and issues after install.
TopChoice takes a curated approach by limiting each city to just five recommended heat pump installers. This avoids the clutter common in open directories and makes it far easier to compare your options without endless scrolling.
Choosing a heat pump installer can be a big decision — and it's hard to know who to trust. We do the legwork, so you can shortlist quickly and reach out with confidence. Every heat pump installer on our lists is independent, local, and chosen on merit. Featured placements may be available and are clearly labelled, but they never influence the editorial rankings.
Pricing depends on unit type (standard vs ducted), access, electrical requirements, and whether you're replacing an existing system. Get an itemised quote that confirms what's included.
Ducted can be excellent for whole-home comfort, but it's a bigger install and needs design planning. Standard heat pumps are often the best value for single rooms or targeted areas.
Yes — regular cleaning and maintenance helps efficiency, air quality and reliability. If the unit smells, leaks or struggles to heat, it is worth getting checked.
We editorially assess local heat pump installers using a consistent framework — public customer reviews and feedback, evidence of workmanship, clarity of service and quoting, professional standards, and communication quality. We don't host our own reviews; rankings reflect real-world reputation drawn from Google and other public sources.
No. Featured placements are available and clearly labelled, but they do not influence the editorial rankings within our Top 5 heat pump installers lists.
