Your multi-split system gets professional maintenance from a company that doesn't sell or install new units.
Three Things a Professional Service Protects.
The air in every room your family uses. Each indoor head in your home circulates air through its own room independently. Over time, mould and dust build up inside each unit behind the filter where you cannot see it. That is what gets into the air your family breathes in the bedroom, the lounge, and every other room the system serves.
The outdoor unit your whole home depends on. Every indoor head in your system connects to one outdoor unit. When indoor heads aren't maintained, that outdoor unit carries a heavier load every time the system runs. Keeping each head clean and efficient is the most direct way to protect the one part of the system that, if it fails, takes every room with it.
Your power bill across multiple rooms. A multi-split system that hasn't been serviced uses more power than one that has. That inefficiency isn't limited to one room. It runs across every head, every day the system operates.
What your multi-split system loses when it isn't maintained
Every indoor head accumulates its own buildup.Every indoor head in your home accumulates mould and dust over time. As that buildup restricts airflow, each unit has to work harder to heat or cool the room it serves. On a single-head system, that extra load stays in one place. On a multi-split, every head that isn't keeping up adds load to the one outdoor unit handling the whole house.
The outdoor unit carries all of itYour outdoor unit is doing the heavy lifting for every room at once. The more strain it carries over time, the harder it works and the faster it wears. It's also the most expensive part of the system. If it fails, every room loses heating and cooling. Because the outdoor unit on a multi-split carries more combined load than a single-head unit ever would, it's more exposed to the consequences of indoor heads not being maintained.
When every head is clean, the outdoor unit runs as it should.When each head is doing its job properly, the outdoor unit runs at normal load.
What your Multi-Split Restore includes
Your multi-split system accumulates mould and dust in the parts a filter rinse never reaches, independently, in every head. The more heads your system has, the more of that buildup the outdoor unit carries every time it runs. What your Restore covers and why every unit gets its own full service.
The filter and internal components
Behind the filter is where most of the buildup lives. It's the part a standard filter rinse doesn't reach.. Your filter is removed, washed with a specialist cleaning solution and refitted dry. The internal coil is the surface the air passes through to be heated or cooled. The internal fan moves that air. The fan accumulates a layer of organic growth on its blades over time. Left long enough, that causes the unit to vibrate and work harder than it should. Both get a full clean on every visit. This happens in every room. Every unit.
The drain and casing
Your drain removes the moisture each indoor unit produces during cooling. Buildup from inside the unit drips into the drain over time and blocks it. When it blocks, it overflows. The drain is flushed clear and a slow-release tablet dropped in to inhibit future blockages. The outside of every unit and every remote control is wiped down and sanitised on every visit.
The outdoor unit
Your outdoor unit does the heating and cooling for every room simultaneously. Debris builds up around it over time and restricts airflow to the internal coil. The area around it is cleared and the unit washed down on every visit.
The manifold
The manifold is where the refrigerant pipes from all your indoor units connect to the outdoor unit. It's specific to multi-split systems and doesn't exist on single-head installations. Your technician visually inspects the pipe connections and insulation at the outdoor manifold as part of every Multi-Split Restore. The inspection checks for insulation degradation, visible refrigerant staining and any physical damage to the pipe connections. Findings are documented in your condition report. Anything outside MiHT's maintenance scope is noted with a recommendation to engage a refrigeration technician.

What you receive after every Multi-Split Restore.
After every Multi-Split Restore, you receive a single written condition report covering the whole system. Each indoor unit is documented individually. The outdoor unit is documented separately. Before-and-after photographs show exactly what was found in the parts of your system you can't access yourself. The load test result is recorded. The report is the evidence that every room was serviced and every component was measured.

Written notes on every finding, what was done and what needs a follow-up visit
A condition record useful for warranty purposes, insurance or property records
One visit or ongoing care, here's how to choose.
If your system has never been professionally serviced, start with a One-Off Restore. If you want your system looked after year after year without having to think about it, an ongoing care plan is the better option.
Annual Care Plan: Scheduled once per year. Recommended for all multi-split systems in year-round use and for any system installed in a coastal or high-use environment.
Biennial Care Plan: Scheduled every two years. Suitable for systems used seasonally or in low-occupancy properties. Note that condition can deteriorate between biennial visits in older installations.
One-Off Restore: The right starting point if your system has never been professionally serviced or you want to know exactly what condition it's in. From $374 inc GST. Includes the full service and a written condition report. No ongoing commitment required.
Pricing: Multi-Split Restore: $374 inc GST for 2 indoor units and 1 outdoor unit.
Additional indoor units: $189 inc GST per unit.

Common questions about multi-split heat pump servicing in Auckland
A multi-split system has one outdoor unit connected to two or more indoor heads in different rooms. The outdoor unit will have multiple refrigerant pipe connections running to different parts of the house. If your home has two or more indoor heat pump units but only one outdoor unit, you have a multi-split. If each indoor unit has its own separate outdoor unit, those are individual systems and are serviced under a standard wall and floor heat pump Restore. If you are not sure, note your system configuration when booking and we will confirm before the visit.
Yes. Each indoor unit on a multi-split system can be individually controlled, scheduled, and set to its own temperature. This is one of the key advantages of a multi-split over a ducted system. The one constraint to be aware of is that all indoor units on the system must operate in the same mode at the same time: all on heating, or all on cooling. You cannot run one room on heating and another on cooling simultaneously. Within that constraint, each room operates independently.
Annual professional servicing is the standard for multi-split systems in year-round use.. Systems with three or more indoor units, homes with pets or high dust levels, and households with occupants who have respiratory sensitivities benefit from servicing every twelve months. With a multi-split, each indoor unit is accumulating its own buildup at the same time. The combined effect on the outdoor unit is greater than it would be on a single-head system, which is why keeping up with regular servicing matters more, not less. The Home Energy Health Assessment takes about three minutes and gives you a personalised result based on your own system.
MiHT services all major multi-split heat pump brands operating in New Zealand, including Mitsubishi Electric, Panasonic, Fujitsu, Daikin, LG, Samsung, Toshiba, Hitachi, and others. The Multi-Split Restore process is brand-agnostic: the same process applies to every indoor unit regardless of manufacturer. MiHT does not install, so there is no brand affiliation and no incentive to recommend one make over another. If you are unsure whether your system is covered, contact us before booking and we will confirm.
Book online, 24 hours a day. Select your service type, choose a time that suits you and receive instant confirmation. On the day of your service you'll receive a live tracking link so you know exactly when to expect your technician. The full Restore takes two to four hours depending on system size.
Each indoor unit in a multi-split system accumulates its own buildup independently. The internal fan in one room develops its own layer of organic growth. The internal coil in another builds up its own contamination. Servicing without individual containment risks circulating contamination from one room to another. MiHT installs a separate wash bag and full site protection in each room before beginning work. Each unit is treated as its own service. The system is only tested as a whole at the end, once every unit has been individually restored.
The manifold is where the refrigerant pipes from all indoor units connect to the outdoor unit. It's specific to multi-split systems and doesn't exist on single-head installations. MiHT includes a visual inspection of the pipe connections and insulation at the outdoor manifold as part of every Multi-Split Restore. The inspection checks for insulation degradation, visible refrigerant staining and any physical damage to the pipe connections. Findings are documented in the condition report. Any issues outside MiHT's maintenance scope are noted with a recommendation to engage a refrigeration technician.
Once every indoor unit has been restored, all heads are operated simultaneously. This tests that the outdoor unit can handle the full combined load of the system without triggering a fault or error code. A single-unit service can't perform this test, because the outdoor unit is never asked to run every head at once. The load test result is documented in your condition report. A clean load test confirms the system is performing as designed across every room. An error code during the load test is documented.
Professional maintenance by a qualified technician supports rather than affects a heat pump warranty. Most manufacturers require evidence of regular maintenance, and a lack of service history is more likely to affect a warranty claim than a documented service record. The condition report produced at every MiHT Multi-Split Restore provides written evidence that every indoor unit and the outdoor unit have been professionally maintained. Manufacturer warranties typically exclude damage caused by neglect, which regular professional servicing is designed to prevent. For specific warranty questions, refer to your unit's documentation or contact the manufacturer directly.
