Authorised installer across the Waikato, King Country, Coromandel & Bay of Plenty
NZ's most-installed heat pump brand — installed properly
Mitsubishi Electric is the most-installed heat pump brand in NZ homes for good reason — quiet operation, strong cold-weather performance, long warranty, and a depth of range that covers every room size, house type, and budget.
Airmax is an authorised Mitsubishi Electric installer. That means we're trained directly by Mitsubishi Electric NZ, we install to their specifications, the full 5-year manufacturer warranty applies, we have direct technical support, and we use genuine parts on every service and repair.
Six reasons we recommend Mitsubishi Electric for most homes
NZ market leader
Mitsubishi Electric has been the most-installed heat pump brand in NZ homes for over a decade. The build quality and reliability are why — and why we recommend them as our default for most installs.
Quietest in their class
Modern Mitsubishi Electric high-wall units run at 18–19 dBA on low setting — quieter than a whisper. That matters most in bedrooms, home offices, and open-plan living areas.
Strong cold-climate performance
Mitsubishi Electric units (especially with HyperCore variants) maintain rated heating output down to -15°C — important for King Country, Te Kuiti, and Te Awamutu winters that drop well below zero.
Long manufacturer warranty
Mitsubishi Electric heat pumps come with a 5-year residential warranty on the unit when installed by an authorised installer like Airmax — among the longest warranties on the NZ market.
Smart Wi-Fi control
Most Mitsubishi Electric units now ship Wi-Fi-ready (or with adapter), controllable via the MELCloud app. Remote schedule, geofencing, energy tracking — all from your phone.
Genuine parts & support
As an authorised installer, we have direct access to Mitsubishi Electric NZ for technical backup, genuine parts, and warranty claims. No third-party parts, no chasing the importer.
The Mitsubishi Electric range we install
Mitsubishi Electric's NZ range covers every room size, house type, and aesthetic preference. Below are the model series we install and service most across the Waikato.
MSZ-AP High Wall Series
The mainstay range for NZ homes — high-wall heat pumps from 2.5kW to 9kW. Quiet operation, energy-efficient inverter tech, Wi-Fi ready. Our default recommendation for most rooms.
MSZ-AP details →EcoCore Designer Series
Premium designer heat pumps in Rich Black Diamond, Matte Silver, and Pure White finishes. For homes where the look of the unit matters as much as performance.

Mitsubishi Electric's quietest premium range — 19 dBA, Plasma Quad Plus filtration, 3D i-See sensor, dual barrier coating. Optional HyperCore variant for -15°C operation.
View premium range →Floor Console (MFZ)

That means we install to Mitsubishi Electric's specifications, the full manufacturer warranty applies, we have direct technical support from Mitsubishi Electric NZ, and we use genuine parts on every service and repair.
What's the best Mitsubishi Electric heat pump for a NZ home?
The Mitsubishi Electric MSZ-AP series is the best heat pump for most NZ homes — strong heating and cooling in a single unit, quiet operation, energy-efficient inverter technology, and Wi-Fi ready. For premium homes, the EcoCore Designer or Black Diamond LN series add quieter operation, advanced filtration, and designer finishes. We confirm the right model after a free site visit.
How much does a Mitsubishi Electric heat pump cost installed in NZ?
A Mitsubishi Electric heat pump in NZ typically costs $2,800–$4,800 installed for a single high-wall MSZ-AP unit, $3,500–$5,500 for the premium Black Diamond LN range, and from $11,000 for a fully ducted PEA Splittable system. Pricing depends on capacity (kW), installation complexity, and any add-ons like Wi-Fi adapters or zone controllers. We provide fixed quotes after a free site visit.
What's the warranty on Mitsubishi Electric heat pumps?
Mitsubishi Electric heat pumps come with a 5-year residential warranty on the unit when installed by an authorised installer like Airmax, plus 1 year on labour and parts. Commercial warranties differ — typically 1 year. Annual servicing is required to keep the warranty valid; we offer service plans to handle that automatically.
Do Mitsubishi Electric heat pumps work in cold Waikato winters?
Yes — Mitsubishi Electric heat pumps are designed for NZ conditions and maintain rated heating output down to -15°C ambient on HyperCore-equipped models, and to around -10°C on standard models. That covers every Waikato winter including the coldest King Country mornings. Sizing the unit correctly for the room is more important than worrying about cold-weather performance.
Can Mitsubishi Electric heat pumps be controlled by phone?
Yes — Mitsubishi Electric heat pumps with the MAC-587IF-E Wi-Fi adapter (built into most current models or sold separately) work with the MELCloud app for iOS and Android. The app gives you remote on/off, schedule, mode switching, energy tracking, and geofencing — useful for holiday homes, rentals, or just turning the heat pump on before you get home from work.
Do you service and repair Mitsubishi Electric heat pumps?
Yes — we service and repair Mitsubishi Electric heat pumps across the Waikato, King Country, Coromandel, and Bay of Plenty, including units we didn't install. As an authorised installer we have direct access to genuine parts and technical support from Mitsubishi Electric NZ, which makes diagnosis faster and warranty claims smoother.
What other brands do you install?
Beyond our authorised Mitsubishi Electric work, we also install heat pumps from Daikin, Hitachi, Fujitsu, and Panasonic across the Waikato. If you have a preference, we'll spec your install around your chosen brand. If you don't, we'll usually recommend a Mitsubishi Electric model because we know the range deeply and the warranty support is direct.
