Choosing between a ducted heat pump vs high-wall heat pump isn’t as straightforward as most people think. Both use the same underlying technology, both run on electricity, and both heat and cool your home efficiently. But get the wrong one for your situation, and you’ll either overspend on a system you don’t need, or end up with something that doesn’t actually keep your whole home comfortable.
We break down what a ducted heat pump is, how it differs from a standard one, what they cost to run, and which one makes sense for your home.
Quick Answer:
Both systems work the same way at their core. They pull heat from the outside air and move it into your home in winter, then reverse the process in summer to cool things down. The difference is in how that conditioned air gets delivered.
A standard heat pump has a wall-mounted unit in each room you want to heat or cool. You see it, you can hear it (a little), and it does a great job for the room it’s in.
A ducted heat pump system runs ducting through your roof space and delivers air through ceiling grilles. The system itself is almost entirely hidden. All you see is a wall controller, an air intake grille in the hallway, and a ceiling grille in each room.
The outdoor unit works the same as any heat pump. But instead of blowing conditioned air directly into one room, it feeds into a central indoor unit sitting in your roof cavity. That unit pushes air through a network of insulated ducts, out through ceiling grilles, and into each room you want to heat or cool. One system, multiple rooms, virtually no noise inside the house.
Standard heat pumps are a great fit for targeted heating or cooling. If you mostly need to warm up the lounge in the evening, or keep the main bedroom cool through summer, a single-room or multi-head heat pump gets the job done well and at a lower upfront cost.
They’re also easier to install in most existing homes since there’s no need to run ducting through the roof space.

If you want whole-home comfort at a consistent temperature, a ducted heat pump system is hard to beat. Nice Air installs ducted systems that heat or cool every room in the house from a single outdoor unit, with no bulky wall units in sight.
Wondering how ducted heating works? The system is virtually silent inside the home. There’s no noise from a wall-mounted unit blowing air across the room. You just feel the temperature change.
Ducted systems also come with zone control options. Zone control means you can turn individual rooms on and off. With room-by-room temperature control (available from around $9,990 installed), you can set a different temperature in every room. Nice Air offers this through Fujitsu General’s anywAiR system, which includes a Wi-Fi touchpad controller and an app so you can adjust settings from anywhere.

When comparing ducted heat pump vs high wall, both systems are significantly cheaper to run than gas heating or electric resistance heaters. But here’s where ducted heat pump systems stand out.
For every 1kWh of electricity used, a ducted heat pump produces around 4kWh of heating output. That’s 400% efficiency. Compare that to a gas heating system, which produces roughly 1kWh of heat per 1kWh of energy used. Nice Air puts the cost comparison plainly: at current electricity rates, a ducted heat pump costs about half as much per kWh of heat delivered as gas heating does. Compared to electric fan or oil column heaters, it’s around 75% cheaper to run.
Unlike a gas system, a ducted heat pump also cools your home in summer. Gas heating doesn’t.
Nice Air’s ducted systems start from around $6,990 installed. Systems with room-by-room temperature control start from around $9,990. Larger homes may require a larger system or multiple systems, which can affect the final price.

Not sure what a ducted heat pump is or whether it’s right for you? For most Hamilton and Tauranga homeowners wanting whole-home comfort, a ducted heat pump system is hard to beat. It’s hidden, quiet, efficient, and gives you the flexibility to heat or cool every room from a single system. But if you only need one or two rooms conditioned, a standard heat pump does the job well at a lower upfront cost.
The best way to know for sure is to talk it through with someone who knows both systems inside out. Nice Air offers a free home consultation across Hamilton, Tauranga, and the wider Waikato and Bay of Plenty regions, so you can get a recommendation that’s based on your actual home rather than a guess.
Yes. Nice Air regularly retrofits ducted systems into existing homes, provided there’s adequate roof space for the ducting and indoor unit.
Nice Air installs Mitsubishi Electric and Fujitsu General ducted systems. Mitsubishi’s Wi-Fi zone control and Fujitsu General’s anywAiR room-by-room temperature system are both available.
Fujitsu General ducted systems installed by Nice Air come with a 6-year parts-and-labour warranty.
Effectively, yes. Both terms are often used interchangeably. However, the difference is that ducted air conditioning only cools, while a ducted heat pump provides both heating and cooling through a single system.
Zone control lets you turn rooms on or off. Room-temperature control (like Fujitsu General’s anywAiR system) lets you set a specific temperature for each room. Nice Air can walk you through both options during a free consultation.
