Experience Working With Leading Brands
We replace and upgrade heat pumps from brands we know well, including Panasonic, Daikin, and Mitsubishi Electric. That matters because each brand has its own quirks, parts, controls, and installation requirements. Whether you’re doing a like-for-like swap or stepping up to a newer model, we take care of the details that keep performance reliable and warranties intact.

A reliable heat pump replacement comes down to correct sizing, correct placement, and correct commissioning. Here’s why customers choose Air Conditioning Group.

We remove the existing unit, handle refrigerant correctly, and dispose of old components responsibly.

excellent team, installation went very well, I'm very pleased,
would certainly recommend.
Very efficient install, great communication and really easy to deal with. Would recommend to anyone needing heat pumps installed.
Steve and the team provided excellent service from start to finish. Steve came out for a quote within hours of my initial enquiry. He was patient with me bumbling my way around the old aircon and heatpump units and helped me find an economical solution to bring my heating up to Healthy Homes specification and double-checked the assessment to ensure that we chose the right wattage and capacity.
Apart from its utility, the unit, a 73KW Panasonic number looks a million bucks in situ and has subtly facelifted the space on account of being a more modern, white unit.
Regretfully, I have forgotten the name of the technician who came to do the installation but he was excellent and updated the circuitry which will solve some issues with tripping the previous setup had.
They removed the old unit while they were at it and placed the outtake in a better location even though it was a last minute change.
effective product after paying $14,000. Do not recommend.
The installation team were fast, efficient and friendly to chat with, all of the rubbish was removed from the premises and the house was as clean as it possibly could be, in view of the muddy state of the garden. The quote was less than at least two competitors.
The ducting has all been put in the ceiling, so there are no unsightly ducts running all over the place, this is over and above what I thought I was quoted for , furthermore I was relieved to establish that my ceiling was quite clean and that there are no rodents in there (additional free service) which is very much appreciated, based on my fear of the fury little fiends!!!
During the course of the installation, the lawnmower guy came and did the lawns, as he came through the gate, some of the grass and mud splashed onto the white outside wall. Quite some time later, one of the team used the outside hose to clean off his ladder, he noticed the messy wall and used the hose to clean it off, while he was there.
Wow, just wow, it's the little things like that which turn a positive customer experience into an absolutely delightful one!!
I have no hesitation in recommending or even actively encouraging other customers to use this service.
Air Conditioning Group is a credit to all New Zealand installers and I only wish that other companies showed the same pride, expertise and exceptional customer service that I witnessed today.
Signing off, in shorts and a T shirt admiring my beautiful air conditioning with a Pinot Gris!!
Again, thank you for your excellent service!

Was upfront at quoting about need for using of powerboats due to size of unit ( and the only persons to do so! ) very very professional.

The recommendation and selection of units to use was done well.
Matt and his install team were helpful, clear and efficient, gave us a head's up on some maintenance he though we might like to look into they noticed when in the roof space (not related to them) also returned to reposition one of our vents after we felt it was in the wrong position with no questions asked or additional cost.
Will definitely use again should the need arise.
Once they arrived at my home, Steve and Matt quickly assessed the situation and provided me with a detailed plan of action. They were able to fix my air conditioning unit in no time at all, and I was blown away by their knowledge and skill.
Not only did Steve and Matt do a fantastic job, but they were also incredibly polite and friendly. They made sure to clean up after themselves and even gave me some tips on how to maintain my air conditioning unit in the future.

Heat Pump Replacement FAQs
This depends on a few factors. A like-for-like swap, in the same area, will often be cheaper than a completely different type of heat pump installed in a new location. Reach out to our team with a little information on what you’re looking for, and we can provide a tailored quote.
We recommend servicing over replacement when you’re experiencing a one-off issue. However, if you’ve had your heat pump for a while and you notice recurring problems, heat pump replacement often becomes a more cost-effective solution than constant maintenance.
We offer heat pump replacement and a range of other heating and cooling services across the wider Auckland region. Unsure whether you’re within our area of service? Reach out to our team.
