We recommend a professional service once a year, and that's the same advice you'll get from the manufacturers. In Rotorua it matters more than most places, because sulphur in the air works away at coils and connections continuously. An annual visit catches corrosion and wear early, while it's still a small job. In between services, cleaning your own filters every three months will keep the system breathing properly.

Our technician checks the overall operation of the unit in both heating and cooling, cleans the filters and indoor coils, clears the drains, inspects electrical connections and flare fittings, checks refrigerant levels, clears debris from the outdoor unit, and inspects your sulphur corrosion protection, reapplying it where needed. You'll get a clear rundown of the system's condition before we leave, along with anything worth keeping an eye on.

Yes, and we'd encourage it. Filter cleaning is straightforward once you've been shown how, and it makes a real difference to efficiency and air quality. If you run your heat pump year-round, aim for every three months. Ask our technician at your next service and they'll walk you through it on your own unit. Filter cleaning doesn't replace an annual service though, as most of what we check sits behind the filters.

Rotorua's geothermal activity releases hydrogen sulphide into the air. It reacts with the copper and aluminium used in heat pump coils, fins and electrical connections, causing corrosion far faster than in other parts of New Zealand. You'll often see it first as a dark film or visible rust on the outdoor unit. Left alone, it reduces efficiency, and eventually causes refrigerant leaks and component failure. It's the single biggest reason heat pumps in Rotorua don't reach their expected lifespan.

Yes. Protection is most effective when applied before installation, but existing systems benefit too, and it's one of the most cost-effective things you can do for a heat pump in Rotorua. We'll assess the current condition of your unit, treat the vulnerable components, and let you know honestly whether corrosion has already progressed too far for treatment to be worthwhile. Once applied, we check and reapply it as part of your annual service.

It certainly helps. Most manufacturers expect systems to be maintained properly, and a documented service history protects you if you ever need to make a warranty claim. Because we're an authorised service agent for Panasonic, Mitsubishi Electric and Daikin, work carried out by our team is done to manufacturer specification using genuine parts, so your warranty stays intact.

Absolutely. We service and repair most makes and models across Rotorua and the wider Bay of Plenty, whether the system came from us or not. Plenty of our service customers inherited their heat pump with the house, or bought it years ago from someone no longer in business. You're just as welcome.

We're available 24/7 for urgent repairs and we prioritise systems that have failed completely, particularly in the middle of winter or for households with young children, elderly residents or health needs. Give the office a call on 07 348 5149 and we'll let you know honestly when we can be there. For non-urgent faults and annual servicing, we'll book a time that suits you.

It depends on the age of the system, the cost of the repair, and how efficiently it's still running. As a rough guide, if a unit is over ten to twelve years old, needs a major component like a compressor, and is costing more to run each year, replacement usually makes better financial sense. If it's younger and the fault is straightforward, repairing is almost always the smarter option. We'll give you our honest assessment either way, including what a replacement would cost, so you can make the call with the full picture.
