Can a Heat Pump Installer Recommend the Best Brand, or Are They Brand-Tied?

Many NZ homeowners are surprised to discover that not all heat pump installers give brand-neutral advice. Some installers are authorised dealers for one or two specific brands, while others work across a wider range. Understanding the difference helps you make a more informed decision — and potentially save money or get a better-suited system for your home.

Brand-Tied vs Independent Installers

Brand-tied installers (sometimes called authorised dealers or preferred installers) have a formal relationship with a specific manufacturer. They may receive training, rebates, marketing support, or preferential pricing in exchange for promoting and installing that brand. This isn't necessarily a bad thing — authorised installers often have deep product knowledge and access to manufacturer warranties — but it does mean their recommendation may be limited to one brand's range.

Independent installers can quote across multiple brands and are more likely to match the system to your specific needs rather than their supplier relationship. However, "independent" doesn't automatically mean better — the quality of the installation itself matters just as much as the brand chosen.

Common Heat Pump Brands in New Zealand

The NZ market is well-served by a range of reputable brands. Some of the most widely installed include:

All of these are legitimate, well-supported brands in New Zealand. The "best" brand for your home depends on factors like room size, insulation levels, climate zone, and budget — not just brand reputation.

How to Tell If Your Installer Is Brand-Tied

It's perfectly reasonable to ask your installer directly:

• "Are you an authorised dealer for a specific brand?"
• "Can you quote me on more than one brand?"
• "Do you receive any incentives for recommending this brand?"

A trustworthy installer will answer these questions honestly. If they only ever recommend one brand without explaining why it suits your situation, that's worth questioning. A good installer should be able to explain why a particular unit suits your home — room volume, ceiling height, insulation, orientation, and local climate all play a role.

What Makes a Good Recommendation?

Regardless of brand, a quality installer should:

• Assess your space properly — measuring the room or zone to be heated/cooled and calculating the required kilowatt (kW) capacity
• Consider your climate — NZ's climate varies significantly from Northland to Southland; cold-climate models (rated to operate at -15°C or lower) matter in colder regions
• Check your insulation — a well-insulated home needs a smaller unit; BRANZ has good guidance on insulation and thermal performance
• Discuss running costs — inverter-driven units are more energy-efficient; Energywise provides useful comparisons on heating efficiency
• Explain warranty terms — manufacturer warranties vary; authorised installers often unlock extended warranties

Licensing and Restricted Work

In New Zealand, the electrical connection of a heat pump must be carried out by a registered electrician — this is restricted electrical work under the Electricity Act. The refrigerant handling side of the installation also requires a person with the appropriate refrigerant handling certification. Always confirm your installer holds the relevant credentials. You can check electrical worker registrations through the Electrical Workers Registration Board (EWRB).

Building consent is generally not required for a standard wall-mounted heat pump installation under Schedule 1 of the Building Act, but always confirm with your local council before proceeding, as circumstances vary.

⚠️ Safety note: Never attempt to connect a heat pump to your electrical supply yourself. This is restricted work and must be completed by a licensed electrician.

Getting Multiple Quotes

The best way to protect yourself from brand-biased advice is to get at least two or three quotes from different installers. This lets you compare:

• Brands and models recommended
• Capacity (kW) of the unit proposed
• Installation costs
• Warranty terms
• Energy star ratings

You can find qualified local heat pump installers on tradedirectory.co.nz to compare your options.

When to Call a Professional

Always use a qualified, licensed installer for heat pump work. This applies whether you're installing a new system, replacing an existing unit, or relocating an indoor head unit. If you're a landlord, note that heating requirements under the Healthy Homes standards specify minimum heating capacity — a professional installer can confirm your unit meets these requirements.
