Mitsubishi Electric is the brand I see most in Auckland homes and there's a reason for that. They keep heating properly when it gets cold outside, where cheaper units start struggling. Quiet indoors, solid warranty, and parts are easy to get hold of when something needs fixing down the track.
Mitsubishi Electric has won the Reader's Digest Most Trusted Heat Pump Brand award nine times in eleven years. That is not marketing, that is Kiwi homeowners voting with their wallets after living with the units. Here is what keeps them at the top.
The AP Smart runs at 18dBA indoors. A quiet bedroom sits around 30dBA. This unit runs below that threshold. You can leave it on overnight in a bedroom next to a sleeping child and not hear it.
For every $1 of electricity used, you get $3 to $5 of heat back. That is how heat pumps work. Mitsubishi Electric's EcoCore inverter pushes toward the higher end by adjusting constantly rather than blasting on and off at full power.
Most heat pumps lose grunt as the temperature drops below 5 degrees outside. HyperCore technology keeps producing full output well below zero. The nights you most need the heat are exactly when this matters.
Mitsubishi Electric engineers both units for quiet operation. My Mt Eden specialist positions the outdoor unit carefully relative to your boundary and your neighbours' windows. Nobody wants to be the house on the street that keeps everyone up.
The AP Smart has built-in wifi and energy monitoring. Set a schedule, control it from your phone, or check what it cost to run last week. No extra hardware, no subscription, it is all in the app.
Mitsubishi Electric backs every residential unit with a 5-year parts and labour warranty in NZ. If the unit develops a fault in that time the repair bill does not come back to you. And if it was installed through me, you call us directly.
Mitsubishi Electric make more residential models than most brands. The differences between them matter. Here is what each one does and who it suits.
Every install is different, but these are the typical ranges for supply and installation in Central Auckland in 2026. Your free quote will give you a fixed price for your specific home.
AP Smart or EF Designer. Supply and install. This covers a back-to-back install where the outdoor unit sits directly behind the indoor one. Longer pipe runs are priced up at quote time. No surprises.
One outdoor unit, multiple indoor heads. Price varies by number of rooms and pipe run length. Each job is priced individually at quote time.
Fully hidden in ceiling or floor. Price depends on home size, number of zones and access for ducting. Most popular for new builds and full renovations.
For a full breakdown see our heat pump installation cost guide. The Warmer Kiwi Homes subsidy can reduce the high-wall cost significantly if you qualify.
Most installation problems come down to two things: wrong size and wrong position. Too small and it runs flat out all day. Wrong position and the airflow never reaches the far end. He checks four things before he quotes:
My Mt Eden specialist holds an EPA Refrigerant Handling Licence. A registered electrician handles all wiring. He applies corrosion protection to every outdoor unit as standard, because Mitsubishi Electric's own warranty documents flag this as a specific risk in New Zealand conditions. It costs you nothing extra.
Most installers disappear once the unit is on the wall. He does not. He handles every service and repair for his own customers. Annual service to keep the warranty valid, a question three years down the track, anything that comes up: you call him. He installed it, he knows it, and he will look after it. He does not work on heat pumps he did not install.
The Warmer Kiwi Homes grant covers up to 90% of the cost, capped at $3,450. Most eligible homeowners pay just $400 to $700 out of pocket. My Mt Eden specialist is a registered provider and handles all the paperwork. Takes 2 minutes to check your eligibility.
Which Mitsubishi Electric model is right for my room?
For most rooms the AP Smart is the answer. It is quiet, efficient and well priced. If noise is your priority above everything else, the AP Smart is hard to beat at 18dBA. If the look of the unit matters, the EF Designer gives you colour choices and a slimmer profile. If the room is south-facing or hard to heat, the KW RapidHeat gets there faster and keeps going when it is cold outside. My Mt Eden specialist assesses the room when he comes for the quote and tells you exactly which one fits.
How long does the install take?
A standard high-wall install takes a few hours. Multi-room systems usually take a full day. Ducted systems take one to two days depending on the size of the home. He confirms the timeframe when he comes out for the quote.
Do I need council consent?
Usually not. Heat pump installation is a permitted activity under the Building Act, which means no consent required in most cases. The one thing to watch is how close the outdoor unit ends up to your boundary, because there are noise rules that apply. He checks your site at quote time and flags anything before he starts, not after.
What warranty does a Mitsubishi Electric come with?
Mitsubishi Electric offers a 5-year parts and labour warranty on all residential heat pumps installed in NZ. That covers both the unit and repair labour if something goes wrong with it. The installation work is separately covered by a 12-month workmanship guarantee on top of that.
Who handles servicing and repairs after the install?
Most installers disappear once the unit is on the wall. My Mt Eden specialist does not. He handles every service and repair for his own customers. Call him directly for your annual service, a warranty check, or anything else that comes up. He installed it, he knows it, and he will look after it. He does not do repairs on units other companies installed.
Do you cover the whole of Central Auckland?
Yes. The specialist I recommend covers Mt Eden and the wider Central Auckland area including Grey Lynn, Ponsonby, Kingsland, Epsom, Sandringham, Balmoral, Mt Albert, One Tree Hill, Royal Oak, Three Kings and surrounding suburbs. Call to confirm your suburb is covered.
