When it's freezing outside, it's tempting to crank the heat pump up to 28°C or even 30°C in the hope that the house will warm up faster. It seems logical, but that's not actually how heat pumps work.

Every commercial property has unique requirements. Factors such as floor area, ceiling height, building materials, window placement, and occupancy levels all influence how much heating and cooling capacity is needed.

The real cost of NH₃ isn't the refrigerant — it's the PSM audits, hazardous area certs, operator licensing, and insurance premiums that come with it. There's a natural alternative: CO₂ (R744). Same performance. Smaller footprint. Drastically reduced compliance burden. Future-proof.

Celebrating the next generation of HVAC & Refrigeration tradespeople at FONKO. Congratulations to Declan, Jonathan, and Gurpinder on completing their apprenticeships and becoming fully qualified tradesmen. Your hard work and dedication have been outstanding. We’re also proud to welcome three new 1st Year Apprentices as we continue investing in the future of New Zealand’s HVAC & Refrigeration industry. Investing in young talent. Building the future of our trade. That’s the FONKO way.

Commercial refrigeration systems deal with far heavier use than residential ones, so over time, even the best setup will start to show signs of wear. It’s not really a question of whether maintenance will be needed, but when. Preventative maintenance gets ahead of those issues early, helping to avoid bigger repair costs, breakdowns, and unnecessary disruption later on.

Cold storage isn’t one-size-fits-all, even though plenty of off-the-shelf options try to be. Prebuilt cold rooms can work in some cases, but for most New Zealand businesses, they come with limitations that show up quickly once they’re in use. Layout constraints, inefficient use of space, and performance gaps are all common issues.

When the Auckland heat kicks in, your heat pump can make the difference between melting and feeling perfectly comfortable. It’s easy to think of it as a winter-only appliance, but it’s just as useful once the temperature climbs. The secret is knowing how to use it right. With the right settings and a few smart habits, you can keep your home cool without the shock of a sky-high power bill.

When your heat pump stops cooling properly, it’s frustrating, especially during a warm Auckland afternoon. The good news is that most of the time, the problem isn’t serious. A few simple checks can solve it quickly, saving you a service call and a sweaty wait.

A cold room isn’t just a big fridge out the back. For supermarkets, restaurants, and food suppliers, it’s the part of the business that makes everything else possible. Stock stays safe, quality stays high, and operations run without disruption. Get it wrong, though, and you’re looking at wasted product, higher bills, and a lot of unnecessary stress.
