      Outstanding execution. The job involved removing gas under floor ducting and replacing with heat pump ducting in our renovated villa. There were many challenges.Heat pump ducting needed to be bigger than the gas ducting and access was limited by downstairs bedroom, steel beams and the vents had to be made slightly larger. In the kitchen there was very poor access due to a structural beam in the way. The gas people just crunched up the pipe and wrapped duct tape around it. ACG custom made a tin trough to perfectly fit in the floor. The system also needed inlet vents for air and this was cleverly accessed and designed using the downstairs hallway and cupboard. All the old rubbish was taken away and the job was left spotless. The final result is much better than the gas system as we now also have cooling in the summer. This was a very complex job and I would doubt other aircon companies would have been able to complete such a skilled job. I highly recommend ACG.

      We needed our air con de-gassed for some other work to be done on our property. Even though Steve said they were fully booked, he went the extra mile to try to help and managed to fit us in at very short notice. The guy who came to do the job was really efficient and good. Thank you so much for the fantastic customer service!

      Fantastic company to work with from start to finish. Communication was clear and consistent throughout the entire process, from the initial quote right through to installation. The installation team was polite, professional, and took great care to ensure everything was fitted perfectly. Couldn’t be happier with the service and the end result. Would highly recommend them.

      Responsive. Affordable. Quick. 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.

      I would give 10 starts to these guys if I could. Steve replied and came around to quote almost immediately after my inquiry. Our layout was a bit tricky, but he figured out the best way to position the heat pumps. On the day, Ethan and Matt turned up on time, which was already a win for me. They were professional, engaging, checkin in with me and being respectful. They worked so hard to finish the install and I couldn't be happier with the outcome. Everything looks and works perfect. Highly recommend to everyone and will be using their services again for my parent's house. Great work team 👍

      Had full house ducted installed this week and so far so good. Good service through and the team did a decent job on the fitting. 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.

      We bought the Diaken central heating system in August 2021. From day one, our lounge of 5 bedroom house, never gets warm enough and mostly is just cold as switched off. We requested help for few times. They attendeded once and replaced the thing and still no effect. Very hard to get in touch. Not so effective product after paying $14,000. Do not recommend.

      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.
