Fujitsu heat pump service, cleaning and maintenance in Auckland
If your Fujitsu heat pump hasn't been serviced in the last 12 months, or you've noticed a smell, weaker airflow, or a power bill that's higher than it should be, get in touch. We'll talk through what it needs before you book anything.
Is this the right service for your situation?
Your Fujitsu heat pump hasn't had a professional clean in the last year. Fujitsu recommends a professional service every 12 months for daily use, or annually in a dusty environment. An unserviced unit can lose 10 to 25 percent of its operating efficiency over time. Filter cleaning alone doesn't reach the internal coil or fan, and ducted Fujitsu systems carry extra scope for duct runs, zone dampers and the air handler.
It's running but airflow feels weak or there's a smell. A blocked filter or a coated internal coil can cut airflow well before the system throws a fault code. A musty smell after cooling mode usually means moisture sitting in a fan that hasn't been cleaned. A proper service clears both.
Your Fujitsu unit is a GENERAL Airstage model. Fujitsu General NZ changed its trading name to GENERAL in 2026, with the range now marketed as Airstage. It's the same manufacturer and the same service process, just a new name on the box.
What a Fujitsu Heat Pump Restore includes
A full clean addresses buildup a filter wash alone can't reach: the internal coil, the internal fan, and the drain line. A well-serviced Fujitsu unit should show a gap of at least 8 to 10 degrees between return air and discharge in cooling mode. We measure this before and after every visit as proof the service worked.
This sits within our full heat pump servicing for Auckland homes.
Internal coil flush
a calibrated wash removes the dust and biofilm layer that builds up on the coil and reduces heat transfer.
Internal fan clean
the fan wheel is pressure washed to remove the mould and grime layer that causes noise and blocks airflow.
Drain line flush
the condensate drain is cleared to stop the algae buildup that causes indoor leaks.
Written condition report
photos, before-and-after notes, and a plain-English summary of the unit's condition, sent after the visit.
Common questions about Fujitsu heat pump service
How often should a Fujitsu heat pump be serviced?
What's Fujitsu's warranty on parts and labour?
Six years parts and labour when installed by a General Airstage Accredited Installer, or five years for a non-accredited install. The residential exclusion that matters is component failure traced to blockage from dust or debris, not a missed service schedule. Regular servicing removes that build-up before it causes a failure.
Does MiHT service GENERAL Airstage systems too?
Yes. Fujitsu General NZ changed its trading name to GENERAL in 2026 and now markets its range as Airstage. It's the same brand and the same service, whichever name is on your unit.
How often do filters need cleaning versus a professional service?
Standard mesh filters should be cleaned every two weeks during normal use. Models with specialised air cleaning filters need a flush every six months and full replacement every three years. Filter cleaning is a homeowner task, but the internal coil, internal fan and drain system aren't accessible without a professional service.
What if my Fujitsu heat pump needs a repair, not a service?
If the indicator lights are flashing after a power reset, or the unit won't turn on at all, that's a repair rather than a service. Check what the light pattern means first, then book a repair diagnosis if the fault doesn't clear.
