We know what you are feeling
Cold Rooms, High Bills, or a System That Never Feels Right?
We repair, replace, and upgrade heating systems so you can finally keep your home warm without wasting energy.
If your current setup never quite made the mark, or if you’re fed up with sky-high power bills, in many homes, the issue comes down to how the system was originally set up, and that’s why we focus heavily on correct sizing, layout, and commissioning. Efficiency problems usually come from things like design mismatches, incorrect sizing, or systems that were never fully commissioned. We’re focused on assessing and correcting those details properly.
At Highlander Heating, we install complete, fully specified systems designed to perform as intended, with all components, all protections, and all controls set up exactly the way the manufacturer recommends. Whether it’s an old villa in Dunedin or a new build-out in Queenstown, we ensure every system is installed, tested and commissioned correctly from day one.

“Thank you so much for the great advice. Knowledgeable and would highly recommend. Went out of the way to give up to date advice.”

Still Unsure If It’s the Right Time?
Here’s what most homeowners ask before they get started.
Yes, most older New Zealand homes can be retrofitted with hydronic systems or air-to-water heat pumps. If professionally designed and installed, even one-hundred-year-old Dunedin villas can enjoy reliable, efficient warmth with minimal disruption.
Design, supply, installation, and commission, Highlander Heating takes care of it all! Clear communication, accountability and a job done properly. No intermediaries, no call centres, just one expert taking care of your project as it should be.
Our systems are a larger initial investment because they’re constructed to be durable and perform well. But the savings can add up quickly. Lower energy use, fewer repairs and a longer life mean better value over time, along with the comfort of reliable warmth through Otago’s bitter winters.
Absolutely. We’ll tune up, service, and sometimes redesign any type of existing heating system, even if another company installed it. Whether it’s minor adjustments or a complete recommissioning, we’ll help your setup run better for longer. If it is fixable, we will find the most cost-effective way.
