Common questions about buying, installing and running a heat pump in Auckland.
Choosing
Which heat pump system is best for me?
A single split is one indoor unit and one outdoor unit, for a single room. A multi split runs several indoor units off one outdoor unit, for several rooms. A ducted system connects one outdoor unit to one or more concealed indoor units and distributes the heat through ducting, so it can do a whole house.
You also choose the indoor unit shape. A high wall is the standard choice for bedrooms and living areas, from $1,071. A floor console sits low on the wall, for rooms with limited wall height, from $1,655. All prices include GST.
What size heat pump do I need?
An undersized heat pump runs flat out and never quite gets there. An oversized one short cycles and costs more than it needed to.
Our sizing tool asks three questions. Give us the room dimensions, pick the room type and how exposed it is, and we show every model that fits, at every price point.
Multi split or ducted for a whole house?
A multi split puts a visible indoor unit in each room, off one outdoor unit. A ducted system heats the whole home from one system, hidden in the ceiling.
Ducted systems are priced on the site two ways, the unit on its own and an all-in supply and install total for a standard scope. from $6,973 to $19,957 including GST, depending on the capacity and the brand
Multi splits are quoted, and we fit Daikin, Mitsubishi and Panasonic multi split systems. Multi split systems are quoted for your house rather than sold at a set price, because the price depends on how many rooms you are heating and how the pipework runs. We fit multi split systems from Daikin, Mitsubishi Electric and Panasonic. Call 0800 393 722 and we will price it.
What is an inverter heat pump?
An inverter uses a variable controlled compressor, so output is adjusted to the exact energy needed to hold your set temperature. Lower output draws less power, which saves energy and holds the room steadier.
Are heat pumps good for allergies and asthma?
Heat pumps carry filters that clean the air as they run. A catechin filter uses static electricity to absorb dust, mould spores and micro-organisms, and inhibits their growth with polyphenol extracted from apples. An ion deodorising filter decomposes odours using ions from an ultrafine particle ceramic. A plasma filter is an electronic air cleaner for dust and odours.
Do you install home ventilation systems?
Yes. 3Yes is a SmartVent dealer and we supply and install the SmartVent residential range across Auckland, Hamilton, Palmerston North and Wellington. Ventilation is a residential service for us.
SmartVent makes two kinds of system. A positive pressure system draws filtered air from the roof cavity and pushes it gently through the house, forcing the damp stale air out through the gaps an older home already has. A balanced heat recovery system extracts stale air and brings fresh air in at the same rate, passing the outgoing air across a core so most of the warmth is handed back to the incoming air, which suits newer, tightly sealed homes. Unit prices start at $1,876 for the SmartVent Lite+ and run to $7,300 for the SmartVent Balance, with installation quoted separately. See the full range on our ventilation page.
Cost and installation
What does a back to back installation mean?
It is the cheapest option, used for wall mounted split systems. The indoor unit is mounted backing onto an exterior wall and the outdoor unit sits directly behind it, back to back. Most homes need exactly this, so we publish that price on every product page. It is also the only kind of install sold on the website.
For a single level house it includes:
- A 4 metre pipe run
- Full installation by certified installers
- Power supply to the unit
- The manufacturer's warranty on the unit, plus one year from 3Yes on the installation and workmanship
If we are installing the unit, delivery to site is included at no extra charge. The delivery rates below apply to unit only orders, where you buy the heat pump without installation.
How much does installation cost?
| Item | Price, incl GST |
|---|---|
| Standard back to back install, single level house | $870 |
| Double storey house, same scope | Add $199 |
| Independent power circuit to the board, COC provided, up to 15 metres | $399 |
| Non standard install, such as long pipe runs or awkward access | Quoted |
Prices are published up front for a standard install, so no quote visit is needed to price a job. Non standard installs are not sold online: email photos of the site to info@3yes.co.nz, or call us, and we will quote it. Ducted and multi split are quoted as well. More on our installation page.
Do you do the electrical work as well?
Yes. We have registered electricians on staff, so the install and the wiring are one job, not two trades. Our installers fit the unit and our electricians handle the wiring, and we take on all electrical work, residential and commercial, whether or not a heat pump is involved. See our electrical page.
Do I need a new power circuit?
On any system over 5 kW cooling bought together with installation, an independent power circuit to the board is included at $399 and cannot be removed. It runs up to 15 metres and a COC is provided. If you buy the unit on its own, without installation, the power circuit does not apply.
What extras can I add to an install?
- Plastic platform for the outdoor unit, $80
- Concrete pavers for an outdoor unit platform, $80 a pair
- Stainless steel wall bracket, $195
- Stainless steel roof bracket, $249
- Custom made to size outdoor unit cover, quoted
- Wi-Fi control, from $44 depending on the system
What does delivery cost?
| Destination | Delivery, incl GST |
|---|---|
| North Island metro | $99 |
| North Island rural | $155 |
| South Island metro | $155 |
| South Island rural | $195 |

Where do you install?
We install and service across Auckland, Hamilton, Palmerston North and Wellington. The business is based in Auckland. If you are outside those areas, email info@3yes.co.nz and we will tell you what we can do.
How soon can you install after I order?
Three to five days from order for a standard install. If the job is urgent we can usually arrange it in one to two days, so tell us when you call.
Running and servicing
How much does a heat pump cost to run?
Heat pumps are efficient because they move heat rather than make it. At 300% to 400% efficiency you pay for roughly 1.5kW of electricity for every 5kW of heating, about a quarter of the cost of electric heating and a third of gas.
What temperature should I run my heat pump at?
Comfort is subjective, but many people find around 22 degrees right. Start there and adjust a degree up or down until it suits you.
How often should a heat pump be serviced?
A full service once a year keeps it running at its most efficient and extends its life. Book it before winter, so it catches problems before the cold sets in. Go to every six months if the unit runs close to non stop, if you are on the coast where salt air corrodes the outdoor unit, or if you have pets clogging the filters. Commercial sites want a service every three to six months. See our servicing page.
What does a heat pump service include?
Indoors we wash the filters and odour covers, clean and disinfect the evaporator coil and blower wheel, check the fan blades for mould, clear the drain pan and condensate line, inspect the electrical terminals and control board, and run the unit in both heating and cooling to confirm it is performing. Outdoors we clean the condenser coil fins and casing, check the coil, drain and electronics for obstructions, inspect the terminals, and check the refrigerant pressures. An anti bacterial treatment on the indoor coil is available as an optional extra. A single wall mounted unit usually takes 45 minutes to an hour and a half.
How much does a heat pump service cost?
Indicative Auckland pricing, including GST, is $120 to $200 for a standard service on a single unit and $80 to $150 for each additional unit done on the same visit. An anti bacterial treatment is $30 to $60 a unit and a refrigerant top up is $80 to $150 per kg. Ducted and ceiling cassette systems run from $250 to $500 and up, because the price follows the size and complexity of the system. We confirm the price when you book, once we know what is on site.
Do you come out after hours?
Yes. An after hours call out is $180, and that rate applies to every site we attend, including refrigeration and commercial work.
What happens if I do not clean my heat pump?
Dust and debris obstruct the air filters, which cuts airflow and efficiency and pushes energy use up. The filters also hold back outdoor pollutants such as pollen and dust, and they can retain moisture, which leads to mould growth.
Will you service a heat pump you did not supply?
Yes. We service all heat pumps, including units another company supplied or installed.
Warranty and brands
What warranty comes with my heat pump?
You get the manufacturer's warranty on the unit, and 3Yes add one year on the installation and workmanship on top of it. The warranty term itself is set by the manufacturer and varies by brand and model, so check the product page for the unit you are looking at. As an authorised dealer we supply the full manufacturer warranty on every brand we sell, not grey imports. Warranty questions go to warranty@3yes.co.nz.
Is the installation work itself covered?
Yes. 3Yes cover the installation and workmanship for one year from the date of install. That sits on top of whatever the manufacturer covers on the unit.
Which brands do you sell?
Seven, as an authorised dealer, 330 models between them: Daikin (72), Mitsubishi (60), Panasonic (53), Carrier (50), Fujitsu (39), Toshiba (38) and Rinnai (18). Browse them all on all heat pumps.
