Air Conditioning Installation Costs VIC 2026 - Get Free Quotes
Air conditioning installation in Victoria involves considerably more than mounting a unit on a wall, and the quality of the work decides whether a system performs for fifteen years or fails in five. Two licences apply to every job, the placement of both units affects comfort permanently, and the commissioning readings are the only evidence you have that it was done properly. Advertised installation prices assume a simple back to back arrangement that many Victorian houses cannot offer. Once the pipe run stretches around a corner or up a storey, additional metres are charged at $60 to $120 each and the base price stops being the price. Electrical capacity is the other common surprise, with a dedicated circuit running $250 to $600 and a switchboard upgrade $800 to $2,500 on older Victorian homes. Outdoor unit placement matters as much as indoor, since a condenser crowded against a fence or baking on a western wall loses capacity on exactly the days you need it. This guide works through the site assessment, both placement decisions, the electrical requirements, what happens on installation day, and the commissioning figures worth asking for.

Cost Depth: Why Two Quotes Differ
When two installers quote wildly different figures for what looks like the same job, the difference is almost never the equipment. It is what each has assumed about the site. One may have priced a back to back arrangement with the indoor unit directly opposite the condenser through a single wall, while the other has walked the house and worked out that the pipework needs to travel eleven metres around two corners. Additional pipe at $60 to $120 per metre accounts for hundreds of dollars on its own. Electrical assumptions differ just as widely, since one quote may include a dedicated circuit at $250 to $600 while another assumes a spare way exists in a switchboard that has none, leaving a $800 to $2,500 upgrade to surface as a variation on the day. Mounting arrangements, height access, core drilling through solid brick, condensate pumps where gravity drainage is impossible, and removal of an existing unit at $150 to $400 all sit in the same category of things that are either priced or discovered.
Refrigerant handling licences are issued by the Australian Refrigeration Council and electrical licensing is administered by Energy Safe Victoria, with installation standards published by Standards Australia. Building permits and practitioner registration sit with the Building and Plumbing Commission, and efficiency programs with the Victorian Government. Consumer rights and domestic building contracts sit with Consumer Affairs Victoria, consumer guarantees with the ACCC, disputes are heard at VCAT, and general information appears at vic.gov.au.
Air Conditioning Installation in Victoria
Installation quality decides more about how a system performs than the badge on the front of it. A Daikin or Mitsubishi Electric unit fitted carelessly will underperform a mid range Fujitsu or Panasonic unit fitted well, and it will do so for its entire working life. Most of what determines the outcome happens in the first two hours and is invisible afterwards. Households have almost no way to judge it once the crew has gone.
Two separate licences apply to every installation, and that surprises people who assume one trade covers the lot. Handling refrigerant is controlled work, since the gas may not lawfully be vented and these systems run at pressures that demand training. Connecting the unit to your electrical supply requires a licensed electrician registered with Energy Safe Victoria, who should issue a compliance certificate afterwards. Some businesses hold both capabilities in house while others subcontract the electrical portion. Either arrangement works provided you know which applies.
The word standard does an enormous amount of work in advertised pricing. A standard installation means the indoor head mounted directly opposite the outdoor unit through a single wall, a pipe run of three to five metres, a spare way available in the switchboard, and ground level access on both sides of the wall. Victorian housing frequently offers none of those conditions, particularly across the older inner suburbs where solid double brick and narrow side passages are the norm rather than the exception. An installer quoting without seeing the property is pricing a house they have imagined rather than yours. Ask any installer directly what their advertised figure assumes about your property. Condensate must run downhill the whole way to its outlet.
Placement decisions are permanent in a way households do not always appreciate until afterwards. Once the wall has been cored, the bracket fixed and the pipework run and insulated, moving either unit means patching a sixty five millimetre hole, making good the render or brickwork, and paying for the labour a second time. Ten minutes spent walking the site and agreeing positions before anybody picks up a drill saves a great deal of frustration later. It is also the only stage at which your preferences cost nothing to accommodate. Nothing about the arrangement can be reconsidered once the pipework is lagged and clipped.
Commissioning is the stage that separates a professional installation from a quick one, and almost nobody thinks to ask about it. Charging the system to the manufacturer's specified weight, holding a proper vacuum to prove the joints are tight, and measuring performance in both modes at handover produces numbers that can be written down and kept. An installer who records those figures without being prompted is telling you something useful about how they work. One who cannot produce them has skipped steps you paid for. The whole exercise takes perhaps twenty minutes at the end of a job. Nobody skips it because of time pressure alone.
Timelines vary more across system types than households expect when they book. A single split system is a half day with two people, a multi split runs one to two days, and a new ducted installation takes two to four days because carpentry and roof cavity work are involved. Replacing existing ducted equipment is considerably quicker, since the ductwork and ceiling outlets usually stay where they are. Ask for the expected duration when booking so you can plan around the disruption. Ducted work in an occupied house is considerably more intrusive than a single split.
The sections that follow walk through the job in the order it actually happens, from the site assessment to the handover conversation. Placement, electrical scope and the Victorian site conditions that shape all of it are covered along the way. Choosing between system types and comparing prices sits under air conditioning costs. Nothing here requires technical knowledge to follow, only a willingness to ask the questions.
What Installation Involves
Knowing the sequence helps you judge whether a quote is complete and whether the work is progressing as it should on the day. Every installation follows broadly the same stages regardless of the system type, and the differences are matters of scale rather than method. Recognising which stage the crew has reached tells you whether the day is running normally. Stages that pass quickly are usually fine, and it is the ones skipped entirely that cause problems later. Watching for the sequence costs nothing on the day. Flattened fins after a storm cost capacity for good.
Assessment comes first and should happen on site rather than over a phone. The installer examines the rooms to be conditioned, the wall construction, the switchboard, the proposed positions for both units and the route between them, then confirms the system type and capacity. A quote produced without that visit is an estimate wearing a quote's clothing. Every assumption inside it becomes a variation once it proves wrong.
Mounting is the first physical step and it sets up everything after it. The indoor bracket goes onto the wall and is checked for level, then a core hole roughly sixty five millimetres across is drilled through to the outside at a slight downward angle. That angle exists so condensate drains away from the room rather than back into it, and getting it wrong produces water damage months later. Getting that fall wrong produces water damage on the wall months later. It is a small detail with disproportionate consequences for the room below. A level checked twice costs nothing at this stage.
Pipework and cabling follow together through the same penetration. Refrigerant lines, the condensate drain and the interconnecting cable all run across to the outdoor unit, insulated continuously along their length and secured at intervals so nothing sags or chafes. On a long run around corners or up a wall, this is the most time consuming part of the entire day. It is also where a rushed installer leaves gaps in the lagging that cost efficiency for years. Insulation gaps are easy to spot before the crew leaves and impossible to fix afterwards.
Electrical connection is done by the licensed electrician rather than the refrigeration technician. A dedicated circuit is pulled through to an isolating switch near the outdoor unit, sized for the equipment and properly protected. This is where a switchboard with no spare way brings the job to a halt. Discovering that now means either an unplanned upgrade or a second visit.
Evacuation and charging come next, and technique matters here more than anywhere else in the job. The pipework is drawn down with a vacuum pump to remove air and moisture, held under that vacuum long enough to confirm it holds, and only then is the refrigerant released or added by weight. Moisture trapped in a sealed circuit reacts with the oil and slowly damages the compressor. Air and moisture left inside a sealed circuit cause acid formation and shorten compressor life, and because the damage is gradual rather than immediate, shortening this step rarely produces a complaint that anybody connects back to installation day. The pump either holds the vacuum or it does not, and that reading is unambiguous.
Commissioning and handover close the job properly. The system runs in both heating and cooling, temperatures and pressures are measured and recorded, the controller is set up, and somebody who actually uses the system is shown how it works. Problems caused by poor installation usually surface as faults months afterwards, and those are covered under air conditioning repairs. By then the connection between the two is easy to miss. Somebody who uses the system daily should be present for the walkthrough. A manual left on the bench is not a handover.
The Site Assessment
The site visit is where a good installer earns their price, and what they choose to look at tells you a great deal about the quality of what follows. An assessment that takes five minutes and never leaves the living room is not an assessment, it is a sales call with a tape measure. What a proper assessment covers is set out below, and none of it is difficult to observe. An installer working through that list is worth the wait for an appointment. Expect the visit to take twenty minutes rather than five.
Room characteristics come first because they drive the capacity calculation. Dimensions including ceiling height, the area and orientation of every window, insulation levels in the ceiling and walls, the number of people usually in the space and any heat producing appliances all feed into the load the system has to carry. A room with large west facing glass behaves completely differently from an identical room facing south, and an installer who does not ask about orientation is guessing at the capacity. An installer who never asks about orientation is guessing at the capacity. That guess is the origin of a great many comfort complaints. Bring up any room that has never been comfortable.
Wall construction determines how the penetration gets made and what it costs in labour. Timber frame behind brick veneer is quick to core, solid double brick common through the older inner suburbs takes considerably longer and produces far more dust, and rendered or clad walls need care to avoid cracking the finish around the hole. Weatherboard brings its own considerations around sealing the penetration against wind driven rain. None of it changes what is possible, only what the work costs in hours. Ask which construction you have if you are unsure, since it shapes the labour estimate.
The switchboard needs inspecting rather than assuming, and this is the single most common source of unexpected cost. Older Melbourne boards frequently have no spare way at all, a great many built before the 1990s still carry ceramic rewireable fuses that cannot accept a modern circuit breaker, and some lack the residual current protection that any new circuit now requires. Photographing the board and sending that image with your initial enquiry saves everybody a wasted conversation. It is the cheapest thing you can do to make a quote reliable. Older boards across the inner suburbs are frequently full to the last way. That single fact accounts for most variations on Victorian installation invoices.
Outdoor positions get assessed for considerably more than convenience. Airflow clearance around the condenser, shade from the western afternoon sun, distance from bedroom windows and from the neighbouring boundary, drainage away from the base, and whether the ground is stable enough for a pad or the wall solid enough for brackets all matter. A condenser dropped into a hot enclosed corner because it was the easiest place to reach will struggle for its entire service life. Walk the possible positions with the installer rather than accepting the first suggestion. Two or three candidate positions usually exist on any property.
Access and the pipe route are the last considerations and they affect the labour directly. How the equipment physically reaches its position, whether ladders or a scaffold are needed for height work, and whether the pipe route has to cross obstacles all add hours to the day. Ducted installations add a roof cavity inspection on top of all of it, as covered under ducted air conditioning installation. Access into that cavity determines a great deal about the price. Photographs of the side passage save an argument about access on the day. Bracket type depends on whether the unit sits on ground or wall.
Indoor Unit Placement
Where the indoor unit ends up affects comfort every single day the system runs, and it is worth having an opinion about rather than leaving to whoever happens to be holding the drill. The default position on a quote is frequently chosen for ease of installation rather than for how the room will actually feel. Raising the question early costs nothing and occasionally changes the answer. A position chosen for the drill rather than the room is a decision you live with daily.
Airflow across the room is the primary consideration. A wall mounted head should throw air along the length of the space rather than into a wall a metre away, and it should not blow directly onto a bed, a desk or a dining table where somebody sits for hours. High level mounting suits cooling because cold air falls naturally through the room, which is why most units sit close to the ceiling. That reasoning is what sits behind an arrangement most people read as a default.
Heating works against that logic, and in Melbourne that matters more than it would further north. Warm air rises, so a high mounted unit in heating mode can leave a comfortable layer at ceiling height while feet stay cold, which is why decent units angle their louvres downward when heating. Floor mounted consoles reverse the trade off, heating a room more effectively and cooling it less effectively, and in a heating dominated climate they deserve consideration rather than automatic dismissal. Few installers raise the console option unprompted, so it is worth asking about. In a Melbourne house the heating performance usually matters more than the cooling. Condensate trays on ducted plant want checking each service.
Obstructions defeat even a well chosen position. Curtains, pelmets, tall furniture and doors left open all interrupt the airflow pattern the unit was designed around, and a head mounted above a doorway pushes much of its output straight into the hallway. Check what sits below and in front of the proposed position before agreeing to it, because that furniture is rarely moved afterwards. That furniture is rarely moved afterwards to suit the unit. Pelmets in particular are easy to overlook when standing in an empty room.
Drainage governs what is physically possible regardless of what looks best. Condensate has to run away under gravity, which means the drain must fall continuously from the unit to a discharge point outside, and a position that cannot achieve that needs a condensate pump instead. Pumps work perfectly well, and they add cost, a small amount of noise and one more component with a service life shorter than the system's. Establishing the drainage path at assessment avoids finding this out with the bracket already fixed.
Proximity to the outdoor unit affects both the price and the performance. Every additional metre of pipe adds refrigerant charge and marginally reduces efficiency, so a position on the same wall as the condenser is cheaper to install and very slightly better in operation. Balancing that against the position that actually suits the room is the real decision, and single room work sits under split system installation. Comfort should usually win that argument. The efficiency penalty over a few extra metres is small in practice. Anything on a roof needs a safe way to reach it later.
Outdoor Unit Placement
The condenser is the component households think about least and the one that most determines whether the system performs as specified. A badly sited outdoor unit works harder for less output, costs more to run every day, and fails years earlier than it should. None of that deterioration is visible on the day the unit goes in. It is worth spending five minutes on the decision even though nobody ever looks at the unit again. Those five minutes affect running costs for fifteen years.
Airflow clearance is the fundamental requirement and the one most often compromised. The unit rejects heat by drawing air across its coil and discharging it out the front, so it needs properly open space ahead of the fan plus clearance at the back and sides, commonly several hundred millimetres depending on the model. Boxing a condenser into a narrow side passage or behind a solid screen strangles it, and the unit then recirculates its own hot discharge air. A strangled condenser recirculates its own hot discharge air. Clearance dimensions are published in every installation manual for a reason. Check the manual's clearance figures against the proposed spot.
Shade makes a substantial difference through a Melbourne summer. A condenser sitting in full western sun on a forty degree afternoon is trying to reject heat into air that is already hot while its own casing bakes, which cuts capacity at exactly the moment the house needs it most. Southern or eastern walls, or a position tucked under the eaves, all perform noticeably better for no additional cost. This is the cheapest performance gain available on any installation. Afternoon sun on the western wall is the worst position available.
Noise is the consideration that produces neighbour disputes, and it is entirely avoidable at the planning stage. Condensers generate a low hum plus fan noise that carries further at night than during the day, so a unit mounted on a shared boundary wall or directly outside a neighbour's bedroom window will eventually become a difficult conversation. Anti vibration mounts and a few metres of thought prevent almost all of it. Sound levels are published for every model sold in Australia.
Mounting method follows from what the site offers. Ground mounting on a concrete pad or purpose made feet is the simplest arrangement and keeps the unit accessible for servicing, wall brackets suit properties with no usable ground space provided the masonry can carry the load, and roof mounting appears where nothing else works at all. Each option carries different cost and access implications, and roof positions in particular need a safe route for whoever services the unit in five years. Whichever applies, the unit needs to stay reachable for servicing. Nitrogen purging during brazing keeps oxidation out of the lines.
Height off the ground matters for drainage and for flood risk. A unit sitting directly on soil draws in leaf litter and debris through the coil and stands in water after heavy rain, so raising it on feet or a pad keeps it clear of both. In an area prone to inundation this is not a small detail, and neither is the mud that splashes up onto the fins. Splashback onto the fins is a slower problem but an equally real one. Purpose made feet cost very little against the difference they make. Debris drawn into a ground level coil shortens its life noticeably.
Service access deserves thought before installation rather than after the first fault. A condenser reachable only by lifting a fence panel or crawling behind a shed costs more to attend and consequently gets serviced less often than it should. Routine attention is covered under air conditioning servicing. A condenser boxed in behind a fence is expensive to attend and gets attended less often.
Electrical Requirements
Electrical work is the part of an air conditioning installation most likely to produce an unexpected variation on the day, and it is almost entirely predictable if somebody looks at the switchboard beforehand. Every system needs a supply of its own rather than sharing an existing circuit. The whole problem disappears with one photograph sent in advance. Very few households think to send it. One photograph of the switchboard sent in advance removes almost all of the uncertainty. Conductor size accounts for distance, not just current.
A dedicated circuit is a requirement rather than a recommendation. Air conditioning cannot share a circuit with general power outlets, so a new circuit runs from the switchboard to an isolating switch positioned within sight of the outdoor unit. Where the board has capacity, that work costs $250 to $600 and adds an hour or so to the installation. Sharing a circuit is not a shortcut an electrician can offer you.
Switchboard capacity is where jobs stall entirely. A great many Melbourne houses built before the 1990s have boards that are completely full, and older ones still running ceramic rewireable fuses cannot accept a modern breaker at all without being replaced. An upgrade runs $800 to $2,500 depending on the board and the property, and that work is covered under switchboard upgrade. That figure is the single largest surprise on Victorian installation invoices. It is also entirely knowable beforehand. A photograph resolves the question before anybody quotes.
Residual current protection applies to any new circuit and is not something an electrician can waive. Where a board lacks it entirely, adding protection for the new circuit forms part of the job, and many households take that moment to bring the whole board up to current requirements rather than doing it piecemeal later. That decision is worth making deliberately with a quote in hand rather than under time pressure on installation day. Doing the board once rather than piecemeal usually works out cheaper. Flare nuts are tightened to a figure rather than by feel.
Three phase supply becomes relevant on larger ducted systems serving substantial houses. A big ducted unit may draw more than single phase can comfortably deliver alongside everything else in the property, and converting to three phase is a significant piece of work that involves the electricity distributor and their timeframes. Establish whether it is needed at quoting stage rather than discovering it when the equipment arrives. Distributor timeframes sit outside any installer's control.
Cable sizing and isolator placement are the details that separate careful work from adequate work. The cable must suit both the current draw and the length of the run, and the isolating switch belongs somewhere a technician can safely reach it without a ladder. Voltage drop over a long run affects performance in ways nobody blames on the wiring. General electrical work sits under electrical services. Filter driers are fitted whenever the circuit is opened. Breaker ratings are set by the equipment data plate.
Installation Day
Knowing what a normal installation day looks like helps you recognise when something is not normal. A single split installation runs three to five hours with two people, and a crew moving considerably faster than that is worth watching. The stages below run in order on almost every job. Preparation, drilling, pipework, evacuation, electrical connection and handover each take their own time.
Preparation begins with confirming both positions before anything is drilled. The installer should mark the indoor bracket location and the outdoor position and walk both past you, because this is the last moment either can change without cost. Floor protection and dust sheets go down at the same time, and their absence tells you something about the standards being applied. Ten minutes here is the last opportunity to change anything without cost.
Drilling the wall penetration is the noisiest and dustiest part of the whole day. A core drill cuts through the wall at a slight downward fall toward the outside, and through solid double brick that takes considerably longer than through a timber frame. Dust control varies enormously between installers, and it is entirely reasonable to ask how they intend to manage it before they start. Solid brick in an occupied house makes a considerable mess without proper dust control. Raising the question before the drill comes out is perfectly fair.
Mounting and pipework occupy the middle of the day. The indoor head goes onto its bracket, refrigerant lines are run and lagged, flare joints are made up and tightened to the specified torque rather than by feel, and the outdoor unit is set onto its pad or brackets. Where joints are brazed rather than flared, the pipework should be purged with nitrogen to prevent oxidation forming inside the lines, and that residue circulating through a new compressor is exactly the sort of damage nobody sees coming. Nitrogen purging costs the installer almost nothing and protects the compressor. This is the stretch where an experienced crew visibly differs from an inexperienced one. Neat, supported, fully lagged pipework is a reasonable thing to expect.
Evacuation takes time that cannot be compressed, and it is where corners get cut most often. The vacuum pump draws the system down to remove air and moisture, and it needs to hold that vacuum long enough to prove the joints are tight rather than simply reaching a reading and stopping. An installer who runs the pump for a couple of minutes and moves straight to charging has not done the job, and nothing visible will indicate that for several years. Nothing visible will indicate a shortened evacuation for several years. Vacuum depth is measured with a micron gauge rather than guessed. Point the fan discharge away from adjoining bedrooms.
Electrical connection and testing follow, and only then does the system run for the first time. The electrician terminates the new circuit, fits the isolator within sight of the outdoor unit and tests the installation before energising anything. A certificate of electrical safety should follow for that work, and it belongs in your paperwork rather than in an inbox somewhere. Ask for that certificate before final payment rather than afterwards.
Cleanup and handover finish the day properly. Offcuts, packaging and drilling dust leave with the crew, the old unit goes with them if one was removed, and somebody walks you through the controller rather than leaving a manual on the bench. Where ducting needed concealing behind dropped ceiling work, that sits under bulkhead and pelmet installation. Leaving the manual on the bench does not count as showing anybody anything. Somebody who actually uses the system should be walked through the controller. A poured base lifts the unit above ground level debris.
Commissioning and Handover
Commissioning is the difference between a system that was installed and a system that was installed properly, and it produces evidence you can keep. Very few Victorian households know to ask for any of it. The measurements themselves take only a few minutes to complete. Asking for it is the difference between hoping and knowing.
Refrigerant charge should be weighed rather than judged. Manufacturers specify a base charge for the unit plus an additional quantity per metre of pipe beyond a stated length, and a technician working with scales is following that specification rather than approximating it. Charging by pressure alone or by feel produces systems that run slightly undercharged for years, delivering less than they should while nobody can point to anything obviously wrong. Scales are not expensive equipment for a business doing this work daily. Weighed charge follows the manufacturer specification exactly. Clearance dimensions are specified in the installation manual.
Leak testing confirms the joints hold before anybody hands over the keys. Pressure testing with nitrogen and electronic leak detection both have their place depending on the installation, and a system losing charge slowly will decline in performance gradually without ever failing outright. That slow decline is the single most common cause of complaints eighteen months after installation, and it traces back to a joint that was never properly tested. Catching a weeping joint now costs nothing compared with finding it in two summers. Anti vibration mounts reduce structure borne noise. Lead times stretch sharply during hot weather.
Performance measurement is quick and highly revealing. Measuring the temperature difference between air entering and leaving the indoor unit shows immediately whether the system is doing what its specification promises, and operating pressures on both sides confirm the charge is correct under load. Both measurements take only a few minutes to complete. Ask for the numbers rather than a verbal assurance that all is well. Superheat readings confirm the charge under working load. Terminal covers protect connections from moisture ingress.
Documentation is the part of the job you keep afterwards. Commissioning readings, the certificate of electrical safety, equipment serial numbers and the warranty registration all belong together somewhere you will find them in four years. Manufacturer warranties frequently depend on being able to produce exactly this material, and reconstructing it later is close to impossible. Reconstructing this material four years later is close to impossible. Isolator switches seize when they are never operated.
The handover conversation matters considerably more than it appears to. Controller operation, where the filters sit and how often to clean them, what the various modes actually do, and what to check before calling anybody out all save future callouts at $120 to $250 each. Symptoms that do warrant a call are covered under air conditioning not cooling or heating. Every avoided callout is $120 to $250 that stays in your pocket. Static pressure readings reveal restricted ductwork. Entry points for cabling are sealed against weather.
Warranty terms deserve reading rather than filing unopened. Most manufacturers require installation by a licensed technician and periodic servicing for the warranty to remain valid, and some require registration within a set window after the installation date. Losing cover on a technicality years later is entirely avoidable with ten minutes of attention now. Registration windows in particular are easy to miss entirely. Weatherproofing the penetration matters on exposed walls.
Victorian Conditions
Four conditions in this state shape how installation should be approached, and a Melbourne installer working across the metropolitan area will raise all of them without being asked. Each affects placement or specification rather than the equipment itself. All four are worth raising before you accept a quote. A local installer will usually mention them without being asked. Airflow measurement confirms a ducted system performs. Condensate pumps introduce a component that can fail.
Older housing stock is the first and it dominates the inner suburbs. Solid double brick construction through Fitzroy, Carlton, Richmond, Northcote and much of the inner north and east means core drilling rather than a quick penetration, and side access across those areas is frequently too narrow to carry equipment through comfortably. Terraces with no side access at all sometimes leave a roof position or a rear courtyard as the only viable option for the condenser. Expect a quote on an older property to reflect that difficulty accurately. Service valves should remain accessible after installation.
Small blocks and townhouse developments are the second and they constrain outdoor positions severely. Melbourne's infill development has produced a great many properties where the only available condenser location is a narrow passage hard against a boundary fence, which puts clearance and neighbour noise in direct conflict. Clearance and neighbour noise come into direct conflict in that setting. Growth corridor housing generally offers more room to work with.
Coastal exposure is the third and it attacks the outdoor unit specifically. Properties around Port Phillip and Western Port, through Frankston, Mordialloc, Brighton and Williamstown and along the Bellarine, see airborne salt corrode coil fins and cabinets years before an inland unit shows any deterioration. Coastal specification units with treated coils and protective coatings exist for precisely this reason, and the premium is modest against replacing a condenser early. Raise the coastal specification question before the equipment is ordered. The premium is small against replacing a condenser five years early. Remote sensors improve control in awkwardly shaped rooms.
Apartment and owners corporation rules are the fourth and they can override every other consideration. Buildings commonly restrict where condensers may be mounted, what noise levels are acceptable, which hours trades may work and whether balcony or facade installation is permitted at all. Some require written approval before anything is fixed to common property, and getting an installer to attend before checking those rules wastes a day for everybody. Lift access usually needs booking as well as approval. Attending before checking the rules wastes a day for everybody involved.
Heritage overlay properties add a planning consideration across the inner suburbs and older country towns. Councils may restrict equipment visible from the street, which can rule out a front facing wall bracket entirely and push the condenser to the rear of the property with a longer pipe run. Establishing that position early avoids an installer arriving with equipment and nowhere compliant to mount it. Council planning departments will confirm what applies to your particular address.
Regional Victoria adds distance and a wider climate range rather than additional complexity. Installers travel further, temperature extremes exceed Melbourne's in both directions across the Mallee and the alpine districts, and dust loading is considerably heavier through the north west. Duct cleaning intervals reflect that difference, as covered under duct cleaning and sanitisation. Filter intervals in those districts need shortening accordingly. Servicing schedules should reflect the local conditions rather than the manual.
What Affects the Cost
Pipe run length is the most common variation on any quote and the easiest to establish in advance. Advertised prices include three to five metres, and additional pipe runs $60 to $120 per metre including the lagging and the labour to install it. A rear bedroom with the condenser at the side adds several hundred dollars. Pacing the intended route gives you a sense of what to expect.
Electrical scope is the second and it ranges from modest to substantial. A dedicated circuit into a board with spare capacity is $250 to $600, a full board upgrade is $800 to $2,500, and a three phase conversion is a larger project again involving the distributor. This is the item to resolve before the day rather than on it. Nothing else on a quote moves as far as this one line. Nothing should block the return grille in any room.
Wall construction affects the labour directly and predictably. Core drilling through solid double brick takes considerably longer than a timber frame penetration, rendered surfaces need care to avoid cracking the finish, and heritage brickwork sometimes calls for a gentler technique entirely. Inner Melbourne housing costs more to work for this reason alone. It is not a premium being charged for the postcode.
Mounting arrangement and working height both add cost. Wall brackets cost more than ground mounting and need masonry solid enough to carry the load, roof positions add access equipment and time, and a second storey indoor unit means working at height for the entire pipe run. Send photographs of both intended positions with your enquiry and most of this can be priced properly rather than estimated. Photographs are worth considerably more than descriptions here. Airflow to individual rooms is trimmed at commissioning.
Condensate handling occasionally forces a pump into the job. Where gravity drainage cannot be achieved from the indoor position, a condensate pump adds a few hundred dollars plus a small ongoing consideration around noise and reliability. It is a simple thing to check during the visit. Ask where the condensate will discharge before the bracket goes on the wall.
Removal of an existing system runs $150 to $400 including recovery of the refrigerant, which is licensed work because the gas cannot lawfully be released. System swaps where old equipment comes out and new goes in are covered under air conditioning replacement and upgrade. Refrigerant cannot lawfully be released to atmosphere. That recovery work has to be done by somebody licensed to do it. Ceiling access hatches make later servicing far easier.
Melbourne and Regional Victorian Pricing
Installation labour holds reasonably steady across metropolitan Melbourne, and the house explains far more of the variation than the postcode does. Wall construction, switchboard condition and access account for most of the difference between two quotes on the same equipment. The tables below cover installation labour and materials on a unit supplied separately. Two quotes on identical equipment can differ by hundreds for site reasons alone.
| Melbourne Area | Split Install | Ducted Install Labour |
|---|---|---|
| Inner Melbourne & CBD | $900-$1,900 | $4,500-$8,000 |
| Northern Suburbs | $700-$1,400 | $3,600-$6,500 |
| Eastern Suburbs | $800-$1,600 | $4,000-$7,200 |
| Western Suburbs | $700-$1,400 | $3,600-$6,500 |
| South Eastern Suburbs | $750-$1,500 | $3,800-$6,900 |
Two characteristics of Melbourne housing explain most of that spread. Inner suburban work involves solid brick penetrations, dated switchboards, narrow side access and frequently no obvious condenser position, all of which consume hours before any equipment is touched. Growth corridor housing offers timber framing, modern boards and open access on every side, which is faster on every count and priced accordingly. Neither observation is a judgement about the properties themselves. Both are simply about the hours the work consumes.
| Regional Area | Split Install | Ducted Install Labour |
|---|---|---|
| Geelong & Surf Coast | $750-$1,550 | $3,900-$7,000 |
| Mornington Peninsula | $800-$1,600 | $4,000-$7,200 |
| Ballarat & Bendigo | $800-$1,650 | $4,100-$7,400 |
| Gippsland | $850-$1,700 | $4,300-$7,700 |
| Wimmera, Mallee & North East | $900-$1,800 | $4,500-$8,100 |
Regional installation pricing reflects travel far more than any difference in the work itself. A technician driving ninety minutes each way carries that time in the quote, and a business with several jobs booked through your district on the same day spreads it across all of them. Asking whether they have other work nearby is a reasonable question and occasionally moves the number. Businesses covering wide districts generally batch their jobs geographically.
Older regional housing frequently needs more electrical work than its metropolitan equivalent. Farmhouses and older town properties through the Wimmera, Gippsland and the north east commonly have boards that predate current requirements entirely, and that work sits on top of the installation rather than inside it. Photograph the board and have it assessed before committing to a figure. Farmhouse switchboards in particular are worth photographing early. A great many of them predate current requirements entirely.
Scheduling is more constrained in regional areas because fewer businesses cover them. During a heatwave a household in the country may wait considerably longer than a Melbourne one, since the same handful of operators serves an area the size of a small state. Booking outside the peak periods matters more here than in the city. Autumn and early spring are the easiest months to get attention.
Combining work into a single visit produces real savings at distance. Installing two or three splits at once, or pairing an installation with a service on existing equipment, spreads the travel component across more billable work. Ask what the difference would be before deciding to do rooms one at a time across separate visits. The saving is usually larger than households expect it to be. Roof cavity temperatures swing enormously through summer.
What to Look Out For
Ask for both licence numbers before booking anything. Refrigerant handling and electrical work are separately licensed, and a legitimate business tells you immediately who holds each without needing to check. Vagueness on this question is the clearest warning sign available to you at no cost. A legitimate business answers without needing to check anything.
Insist on a site visit before accepting any quote at all. Phone quotes rest on assumptions about pipe run, wall construction and switchboard capacity, and every one of those assumptions becomes a variation when it proves wrong. The visit costs the installer an hour of their time and costs you nothing whatsoever. Anybody unwilling to attend is quoting on assumptions rather than observation. Duct insulation ratings vary between suppliers.
Have the switchboard photographed and assessed at quoting stage. It is the commonest source of unexpected cost on a Victorian job, entirely knowable in advance, and discovering a full board on installation day means either an unplanned upgrade or a return visit at your expense. Send the photograph with your first enquiry and the problem largely disappears. It is the highest value thing you can do before booking.
Confirm both unit positions in writing before the day begins. Placement becomes permanent the moment drilling starts, and installers choosing positions for their own convenience is a common complaint after the fact. Walk the site with them and agree both positions out loud. Written confirmation removes any later disagreement about what was said. Flexible duct sags where supports are inadequate.
Ask how long the system will be held under vacuum before charging. Proper evacuation removes air and moisture and takes real time, and it is the most frequently skipped step in the trade precisely because nobody can verify it afterwards. The question itself signals you know what to look for. Expect a specific answer rather than a general reassurance.
Request the commissioning readings at handover rather than afterwards. Temperature differential across the indoor unit, operating pressures on both sides and the weighed refrigerant charge are all quick to measure and record. An installer who produces them without hesitating is one who took them. Keep the figures with your warranty documents. Compliance certificates follow every piece of electrical work.
Get the certificate of electrical safety and the warranty documents before final payment. Certificates are required for electrical work, warranty registration frequently sits with the owner rather than the installer, and contract requirements are administered by Consumer Affairs Victoria. Unresolved disputes are heard at VCAT, and consumer guarantees sit with the ACCC. Ask who is responsible for lodging it before the crew leaves.
What to Look for in a Quote in VIC
An installation quote worth comparing names the model and capacity, states the included pipe run and the rate beyond it, specifies both unit positions, confirms the electrical scope including any switchboard work, states whether removal of an old system is covered, notes the mounting arrangement, and lists what sits outside the price. A single figure against the words supply and install tells you nothing about what has been assumed, and every assumption is a variation waiting to appear. Every unstated assumption is a variation waiting to appear on the invoice. Ask for the detail in writing before comparing anything. Circuit labelling helps whoever attends next.
Send every installer the same information so the comparison means something. Provide room dimensions and ceiling heights, window sizes and orientations, photographs of the proposed indoor and outdoor positions, a photograph of the switchboard, the wall construction if you know it, and your suburb. Say whether you are in a house, a townhouse or an apartment. Identical briefs are the only way quotes become comparable.
Four questions will tell you whether an installer is careful or merely quick. Who holds the refrigeration and electrical licences, how long will the system be evacuated before charging, what electrical work does this house actually need, and will you provide commissioning readings at handover. Specific answers to all four point to somebody worth engaging, and hesitation on any of them is informative. Hesitation on any of them is informative in itself. None of the four requires you to understand the answer technically.
Compare quotes on inclusions rather than on the bottom line. A quote several hundred dollars higher that includes a longer pipe run, a dedicated circuit and removal of the old unit may well be cheaper than a lower one excluding all three. Line them up side by side against the same list and the ranking frequently inverts. The cheapest headline figure is very rarely the cheapest job.
Budget the installation as a whole rather than the advertised figure. Electrical work, additional pipe, mounting hardware and removal add fifteen to thirty per cent over a headline price on a Victorian property. Posting the job on The Quote Yard puts one brief in front of several installers at once, and multi room systems sit under multi split air conditioning installation. Electrical work, extra pipe, brackets and removal all sit outside the advertised number. Fifteen to thirty per cent is a realistic allowance on a Victorian property.
