One living room
A high-wall or floor unit is often the simplest place to start. If glass, joinery or artwork leaves little wall space, we can check whether an AireTile ceiling cassette will fit.

Heat pumps for Otago homes.
A lounge that stays cold in the evening needs a different solution from three bedrooms behind closed doors. We supply and install Mitsubishi Electric heat pumps and can help you choose between a single-room, multi-room or ducted system.

Mitsubishi Electric / Choosing a system
Which rooms matter most?
Start with the room that’s uncomfortable and when you use it. That tells us more than the floor area on its own.
Bedrooms behind closed doors
For two bedrooms that get hot at night, we can compare separate units with an OmniCore multi-room system using one outdoor unit. We check pipe runs, noise near sleeping areas and which rooms need to run together.
Compare bedroom optionsA new build or whole home
Before the ceiling is lined, we can check where the grilles and return air will go, which rooms need their own controls, and how the unit will be reached for servicing. Send your floor and ceiling plans and the lining date if you know it. On compatible ducted systems, optional ZoneIQ can adjust individual room settings within the same heating or cooling mode.
Send floor or ceiling plansFresh air as well as heating
A heat pump generally recirculates indoor air. If you want fresh air with heat recovery, we can assess Mitsubishi Electric Lossnay separately and show what adding it changes in the scope. If condensation is the starting point, compare SmartVent options for your home.
Discuss ventilationFrom the estimating desk
One home, two different heating needs.
A recent pricing brief had a long open-plan living area and a separate bedroom wing. The questions were where the air would reach, how each area would be controlled, and how to fit discreet grilles into the ceiling.
We looked at air supply at both ends of the living area and separate bedroom control. Fresh air was a separate option in the price. That’s the sort of detail we can work through from a floor plan before a builder closes in the ceiling.
Design example · pricing stageFrom enquiry to handover
What you get back.
A recommendation you can compare
We explain the proposed system, the rooms it serves and why it suits your use. For a ducted job, we identify the grille and return-air allowances, electrical work, controls and fresh-air options. The quote sets out what still needs checking on site.
A conversation before the builder needs an answer
Tell us your drawing issue and ceiling-close date. We can agree who needs the answer and when the next update would help. For a Queenstown or Wānaka build, we review the plans from Dunedin and agree travel, installation and service arrangements before booking a visit.
Help after installation
We source Mitsubishi Electric equipment through Black Diamond Technologies, its New Zealand distributor. At handover we’ll take you through the controller, filter care and where to find the model number. If something needs attention, call Leading with that number so we can help identify the next step.
Mitsubishi Electric NZ manuals and support (opens in a new tab)After installation
Already have a heat pump?
Sometimes it’s the controller. Sometimes the room has changed since the unit went in. Tell us what’s happening and we can work out the next step with you.
Help with controls or servicing
If you know the model, send it through with your suburb and what you’ve noticed. A photo of the controller or a displayed fault code helps. Let us know if Leading installed it. We’ll confirm whether we can help by phone, need to arrange a visit or should point you to manufacturer support.
Ask about an existing system →Considering replacement?
Tell us the age if known, how the old unit performs in winter, which rooms are uncomfortable and whether the layout has changed. We can discuss what’s worth assessing before you commit to replacement equipment.
Discuss repair or replacement →Looking after several units?
For a workplace or rental portfolio, start with the locations, approximate number of units and who arranges access. We’ll confirm service coverage and what can sensibly be grouped into one visit before proposing a schedule.
Discuss a maintenance visit →Coastal Otago
Where will the outdoor unit go?
If salt spray reaches the house, tell us which side faces the sea. We’ll check the proposed position, the protection the unit needs and how a technician could reach it for a service. If you’re up the coast, give us the town first so we can confirm travel and future service cover before you commit.

Questions about heating
Will one heat pump warm the bedrooms down the hall?
Don’t assume it will. A closed door limits air movement. Tell us which rooms you want warm at night so we can compare another indoor unit with a ducted option.
Can ducted heating go into an existing house?
Often, yes. We need to see the roof space, access, possible grille positions and the route back to the unit before quoting.
Can different parts of the house have different settings?
That depends on the system and controls. We’ll check which rooms need separate schedules or temperatures and show what zoning is included in the quote.
Is ventilation included in a ducted price?
Only when it’s specified. We show heating and fresh air separately so you can see what each option does.
What should I send for a price?
Send your suburb, a floor plan or room dimensions, which rooms matter most and what heats them now. For a new build, include the ceiling plan and build stage if you have them.
Talk to Leading
Have a floor plan handy?
Send it through with the rooms you want warm and when you use them. For an existing home, a couple of room photos are a good start. You can also talk it through without plans.
