How Often Should a Heat Pump / Air Conditioner be Serviced?

Heat pumps / air conditioners usually need to be serviced every 1–2 years by a licensed technician, depending on the type of system you have, frequency of use and local climate conditions. If the system is run year-round or heavily over summer, yearly servicing is recommended.

In this article, we’ll explain how often to service a Fujitsu heat pump / air conditioner depending on the system, and why keeping up with maintenance makes such a difference to comfort, performance and energy costs.

Why Regular Servicing Matters for Heat Pumps / Air Conditioners

In New Zealand, heat pumps are not just used for heating in winter; they are also a common form of home cooling during summer. Using your system year-round, puts more pressure on the parts and filters. To keep your residential heat pump system running smoothly all year long,  providing reliable comfort without raising energy costs, it needs to be serviced regularly.

Booking professional heat pump service not only avoids unexpected breakdowns but also ensures your system delivers steady comfort when you need it most.

How Often Do Heat Pumps / Air Conditioners Need Professional Servicing?

How often should heat pumps be serviced in NZ often comes down to the type of unit you have.

A wall mounted air conditioner used for a single room may need less frequent servicing compared to ducted air conditioning, which cools or heats multiple areas through a network of ducts and has more components to maintain.

A regular professional servicing ensures the system is cleaned, tested and ready for the new season, reducing the risk of breakdowns and improving efficiency. You’ll have peace of mind that your unit will keep running smoothly, providing reliable comfort no matter the season.

How Often Should Ducted Air Conditioning Be Serviced?

Ducted systems are best serviced on a yearly basis, especially before peak summer or winter months. Because ducted air conditioning cools or heats multiple rooms through a network of ducts, there are more components to maintain compared to a single split system. This includes checking and cleaning the ducts, inspecting the fan coil and ensuring the zone controls are working properly.

When an air conditioner is in constant use or if airflow drops, it’s worth booking a service sooner.

How Often Should a Split System Air Conditioner be serviced?

A split system air conditioner will generally require servicing every 1–2 years, depending on usage. Because split systems cool or heat individual rooms rather than the whole home, they typically require less maintenance than ducted systems. Still, knowing how often to service an AC unit is important for preventing small issues from becoming costly repairs.

It’s also worth keeping an eye out for signs your system may need servicing sooner than scheduled. Unusual noises, weak airflow, unpleasant odours or a sudden rise in energy bills can all indicate your unit is struggling. Booking a service when these issues appear helps prevent bigger problems.

No matter the type of heat pump / air conditioner that you have, regular maintenance will help to maintain air quality, lower energy usage and extend the lifespan of your system.

Recommended Service Schedule for Fujitsu Heat Pumps / ACs

To keep your Fujitsu system performing at its best, it’s important to know how often should a heat pump be serviced. If your unit is running heavily through summer or used year-round for heating and cooling, then at a minimum, it should be serviced once a year. Here are recommended service schedules based on how often you use it and the environment it operates in.

Light use – If your heat pump / AC is only used occasionally or in one season, a professional service every two years may be enough.

Regular or heavy use – For households that run the system daily through summer or year-round with heating and cooling, annual servicing is best.

Environment – Houses close to the ocean or in dusty locations may need extra servicing, as dust and salt can build up and affect performance.

It’s a good idea to start planning your next service ahead of peak seasons, for example, in spring before the summer cooling load or in early autumn before relying on heating for winter. This ensures your system is ready to handle the busiest times of the year without interruption.

Fujitsu recommends using only authorised service agents who understand the technology inside and out. To book your next appointment, find a service agent near you and keep your system performing at its best.
