New Zealand's most popular heat pump type
High wall heat pump supply and installation
Wall-mounted heat pumps for bedrooms, lounges, and open-plan living areas. Supply, installation, and subsidy application handled from start to finish. Papatoetoe and South Auckland.
Why high wall
New Zealand's most installed heat pump type — for good reason
High wall units suit the vast majority of South Auckland homes. Here's why they're consistently the right choice.
Works in almost any room
Mounted high on the wall, out of the way. Suits bedrooms, lounges, and open-plan areas in virtually any home layout — old or new.
Heating and cooling in one
One unit heats in winter and cools in summer. No separate systems needed — especially useful in Auckland's variable climate.
Cost-effective to run
Modern heat pumps move heat rather than generate it — producing around 3–4 units of heat for every unit of electricity consumed, compared to 1:1 for a standard heater.
Quiet operation
Modern high wall units run at low noise levels, particularly premium models from Mitsubishi Electric, Daikin, and Panasonic. Suitable for bedrooms and quiet living areas.
Straightforward installation
Most installations are completed in a single visit. Simpler than ducted or multi-room systems, which keeps installation cost down.
Subsidy eligible
High wall installations qualify for the Warmer Kiwi Homes subsidy for eligible homes. Up to $3,450 off for qualifying homeowners — we handle the application.
Getting the size right
Correct sizing makes all the difference
A unit that's too small won't heat your space. One that's too large will cycle on and off constantly, reducing efficiency and not properly dehumidifying. We calculate the right size as part of every free assessment.
What we assess during your site visit
Heat pump sizing depends on more than just floor area. These are the key factors we consider when specifying the right unit for your home.

Common questions
High wall heat pump FAQ
Answers to the questions we get asked most often.
How long does installation take?
Most single high wall installations are completed in 4–6 hours. We arrive with everything needed and complete the job in one visit, including testing and a walkthrough of the controls before we leave.
Will a high wall unit heat my whole house?
A high wall unit heats the room it's installed in well. Some heat will flow to adjacent areas, but it won't heat your entire home effectively. For whole-home heating, a ducted system or multi-room setup is the better solution.
Where should the indoor unit be positioned?
We position indoor units on interior walls away from direct sunlight where possible, at a height that allows good air distribution across the room. The outdoor unit needs good airflow and protection from prevailing winds — we assess the best location during your site visit.
Do I need electrical work done first?
Most installations require a dedicated electrical circuit. In newer homes this is usually straightforward. Some older homes may need minor electrical upgrades — we assess this during the site visit and factor it into your quote so there are no surprises.
How do I clean the filters?
We show you during installation. The filters slide out easily, can be rinsed under a tap, dried, and replaced. This should be done every few months during heavy use. For a deeper clean of the coils and internal components, see our professional cleaning service.
What if my outdoor unit frosts over?
Modern heat pumps have automatic defrost cycles that handle light frost buildup — this is normal in cold weather. If the unit becomes completely blocked with ice, turn it off and call us. This usually points to a refrigerant issue or a defrost sensor fault.
