We install, service and repair splits and multi-head systems across Sunbury from the depot in town, and we size on the room rather than sell the unit on the van.

Split systems in Sunbury
A split system does one thing well: it heats and cools one room, quietly and cheaply, without ductwork. In Sunbury that is exactly what many households need, whether it is the upstairs bedroom that will not cool down on a January evening, the home office at the back of the house, or a living area in an older home that has never had ducted heating or cooling. We install, service and repair splits and multi-head systems here from our depot in town, with our own technicians and no subcontracted crews. The split system installation page sets out how an installation runs.
Installation sized for the room
The unit is sized on the room’s real load: floor area, ceiling height, insulation, the size and orientation of the windows and how the room is used. In Sunbury the summer load on a west-facing room is the design case, and the winter load on a frosty morning has to be met too. The indoor unit is positioned so the airflow does not blow across the bed or the couch and the outdoor unit for airflow, service access and noise, which matters on a compact estate block. Pipe runs and drains are planned at the quote, particularly on double storey homes where the outdoor unit may be a floor below. Our installation workmanship carries a 9 Year Labour and Workmanship Warranty.
Multi-head systems
Where two, three or four rooms need heating and cooling and a ducted system does not suit the house, a multi-head system runs several indoor units from one outdoor unit. It is the usual answer for an older Sunbury home without ducting, or for a household that wants the bedrooms and the living area conditioned without the cost or roof work of a whole-home system. Rinnai is a primary multi-head brand for us. Our multi-head versus ducted comparison sets out the trade-offs, and where whole-home comfort is what you want, the Sunbury ducted reverse cycle page is the place to start.
Service and repairs
We service and repair split systems of every major brand across Sunbury: Mitsubishi Electric, ActronAir, Rinnai, Daikin, Fujitsu, Panasonic, LG, Samsung and the rest. A service cleans the filters and indoor coil, checks the outdoor unit, drain and electrical connections and tests the system in both modes. A repair starts with the symptom you tell us when you book, so the technician arrives with the likely parts. Our guide on a split system that is not cooling or heating covers the checks you can make yourself first.
The brands
We install Mitsubishi Electric, ActronAir and Rinnai split and multi-head systems. We are factory-trained ActronAir and Rinnai dealers buying direct from the manufacturers, and we have substantial hands-on experience installing and servicing Mitsubishi Electric. We recommend one unit for your room rather than list three.
Local knowledge
What we see in Sunbury
West-facing bedrooms in double storey homes
Sunbury has a high proportion of double storey estate homes, and the upstairs bedrooms on the west side hold heat long into a summer evening. A correctly sized split in the main bedroom is one of the most common jobs we do in Sunbury, and sizing it on the room's orientation and glazing rather than its floor area is what makes it work at nine o'clock at night.
Older homes without ducting
In the established parts of Sunbury there are plenty of homes that have never had ducted anything. For a living area or a couple of rooms a split, or a multi-head system covering two or three rooms from one outdoor unit, gives good heating and cooling without cutting into ceilings, and it is often the better spend than a ducted system in a house that does not suit one.
Compact blocks and outdoor units
Estate blocks put the outdoor unit close to a fence line or a neighbour's window. We position it for airflow, service access and noise, and choose quiet units, so the split is not the loudest thing in the street on a still night. On double storey homes the outdoor unit placement and the pipe run are planned at the quote, not improvised on the day.
Hot, dry summers and cold winters
A Sunbury split works hard in both directions: cooling on 38 degree afternoons and heating on frosty mornings. We select units for their capacity at both extremes, which is why a size that looks fine on a brochure can be wrong for a Sunbury room.
Home base
We are based in Sunbury, so a split system installation, a service or a repair here is often the first or last job of a technician's day and we can usually be flexible on times. Diggers Rest, Bulla and Toolern Vale are covered from the same depot.
Why our installations perform
The MRGA Standard
What a properly designed and installed system includes, and what our quote is built around.
Sized for your home, not a rule of thumb
We size heating and cooling from the home: floor area, ceiling heights, insulation, glazing, orientation and how the rooms are used. An oversized unit short-cycles and an undersized one runs flat out on the coldest and hottest days, which is exactly when you need it.
Outdoor unit positioned properly
Clearances for airflow and service access, a level base or bracket, noise considered for you and the neighbours, and a position that keeps pipe runs sensible. It is the difference between a unit that lasts and one that struggles every summer.
Refrigerant work done by licensed technicians
Pipework is brazed, pressure-tested and evacuated before charging, and the charge is set to the manufacturer's specification. Our technicians hold the ARCtick refrigerant handling licence the law requires.
Electrical supply done by licensed electricians
Reverse cycle systems need the right circuit, cable size and isolator at the outdoor unit, installed to AS/NZS 3000 by a licensed electrician with a certificate of electrical safety. We tell you up front if the switchboard needs work, rather than discovering it on installation day.
Factory-trained dealers
Trained by the manufacturers, buying direct
We are factory-trained dealers for ActronAir, Brivis and Rinnai and purchase equipment directly from these manufacturers.
We also install, service and repair all major heating and cooling brands, including Mitsubishi Electric.
Accountability
9Year Labour & Workmanship Warranty
It applies to the installation work our own team does. Equipment is covered by the manufacturer's warranty, repairs and servicing carry their own workmanship warranty, and pre-existing or reused components are not covered by the nine years.
Split systems in Sunbury: your questions
What size split system do I need for a Sunbury bedroom?
It depends on the room's floor area, ceiling height, insulation, window size and orientation. A west-facing upstairs bedroom in Sunbury needs more capacity than the same room facing south downstairs. We size on the room and will tell you if the size you have in mind is wrong in either direction.
Should I get a split system or ducted?
For one or two rooms a split is usually the better spend. For whole-home comfort in a family home, ducted reverse cycle is usually better, and for two to four rooms without ductwork a multi-head system sits between the two. The site visit settles it; our multi-head versus ducted comparison sets out the trade-offs.
Which brands do you install in Sunbury?
Mitsubishi Electric, ActronAir and Rinnai splits and multi-head systems. We are factory-trained ActronAir and Rinnai dealers buying direct from the manufacturers, and we have substantial hands-on experience installing and servicing Mitsubishi Electric. We service and repair Daikin, Fujitsu, Panasonic, LG, Samsung and other brands as well.
My split is running but not cooling. Can you repair it?
Yes. Tell us the symptom when you book and one of our own technicians comes with the likely parts. Our guide on a split system that is not cooling or heating covers the checks you can make first, including the filter, which is the cause more often than people expect.
Do you service split systems in Sunbury?
Yes. A split system service cleans the filters and indoor coil, checks the outdoor unit, drain and electrical connections, tests the system in both modes and picks up faults before they become breakdowns. Book it with an evaporative or gas heater service if you want one visit.
