Air Conditioning Costs in Victoria

Air conditioning in Victoria runs from $1,100 for a small split system in a bedroom through to $25,000 for a fully zoned ducted reverse cycle system in a large house. A single split system in a living area is the most common purchase at $1,600 to $2,800 installed, and a ducted system for a three bedroom house sits between $9,000 and $16,000. Those figures all assume a standard installation, which many Victorian houses cannot offer. Additional pipe, electrical work and removal of an old unit sit on top.

The thing worth understanding before anything else is that Melbourne is a heating dominated city. The number of days requiring heating substantially exceeds those requiring cooling, which means a reverse cycle system spends far more of its working life warming the house than cooling it. Households who think of the purchase as buying air conditioning are only considering half of what they are actually buying. Household routines should shape the control strategy. A system fought against every day was specified wrong.

That reframing changes which system makes sense. A system chosen purely on cooling capacity may be poorly matched for winter, since heating output falls as the outdoor temperature drops and the specification sheet figure is measured at a temperature Melbourne does not stay at. Asking for the heating capacity at two degrees rather than at seven is the question a good installer will answer without hesitating. Slab or bracket mounting suits different ground conditions. Manufacturers publish heating capacity at seven degrees outdoors. Melbourne mornings routinely sit well below that.

Victoria's shift away from gas heating is the largest single force in this market. Ducted gas heating has been the Melbourne standard for decades and a great many of those units are now reaching end of life, with households deciding whether to replace like for like or convert to reverse cycle. That decision has rebate implications worth checking before anybody quotes. Rebate arrangements for efficient electric appliances change periodically and are worth checking at the outset. Ducted gas heating was the Melbourne standard for decades.

Sizing is where most money is wasted, in both directions. An undersized system runs constantly and never comfortably, while an oversized one costs more to buy, cycles on and off inefficiently and dehumidifies poorly. Neither problem is visible on a quote, and both follow from an installer who sized the system from the room's floor area alone. Two installers can quote the same house very differently. Matching the inclusions is the only fair comparison. Compressor cycling frequency shows whether sizing was right.

The gap between an advertised price and a final invoice is wider in this trade than in most. Additional pipe runs, electrical upgrades, access difficulties and removal of an old unit are all commonly excluded from the headline figure. Establishing what a quote actually includes is worth more than shaving a hundred dollars off it. Written scope is what you rely on if something fails. Reading the exclusions matters more than comparing the headline figures.

The sections below cover each system type, sizing done properly, the gas to electric decision, running costs across a Melbourne year, and the site factors that move the price. Installation detail sits under air conditioning installation. Pricing across Melbourne and the regions follows toward the end. Compare quotes on what each includes rather than the bottom line.

System Types Compared

Five system types cover almost every Victorian installation, and choosing between them is mostly a question of how many rooms need conditioning rather than personal preference. Getting this right first narrows everything that follows. Sizing errors cannot be corrected after installation. Most households overestimate how much system they need before anybody assesses the rooms. Room count drives the choice far more than personal preference does. Start there rather than with a brand.

A split system is one indoor unit connected to one outdoor condenser, and it is the default for a single room or an open plan living area. At $1,100 to $3,800 installed depending on capacity it is the cheapest way to condition a space properly, and modern inverter models are efficient enough to run all day without alarming bills. The limitation is that each room needs its own head unit and its own outdoor condenser. Ask which capacity the installer arrived at and how.

A multi split solves that by running several indoor units from one outdoor condenser, usually two to five heads. At $6,000 to $11,000 for a three head system it costs more than the equivalent individual splits, and it uses only one outdoor unit, which matters enormously on a small block or in a townhouse where there is nowhere to put three condensers. Detail sits under multi split air conditioning installation. Seasonal demand distorts both pricing and lead times. Pipe runs on a multi head system are longer by definition.

Ducted reverse cycle conditions the whole house from a central unit through ceiling or underfloor ducting, at $9,000 to $25,000 depending on capacity and zoning. It is the most expensive option and the only one that delivers even temperatures throughout a house with no visible indoor units beyond the outlets. Zoning is what makes it economical to run, and full detail sits under ducted air conditioning installation. Electrical capacity decides more than households expect.

Cassette units sit flush in a ceiling and blow in four directions, at $3,500 to $6,500 installed. They suit large open plan areas and rooms where wall space is at a premium, and they need ceiling cavity depth to fit. Commercial and larger residential spaces use them most, as covered under cassette air conditioning installation. They need adequate ceiling cavity depth to fit at all. Commissioning readings belong on the handover paperwork.

Evaporative cooling works on a completely different principle and cools only, at $3,500 to $7,000 for a whole house system. It suits Melbourne's dry summer heat well and fails during humid spells, and because it cannot heat it leaves the winter problem entirely unsolved. That combination is why it has lost ground to reverse cycle, and it is covered under evaporative cooling installation. Because it cannot heat, the winter problem is left entirely unsolved.

Split and Multi Split Systems

The split system is the workhorse of Victorian air conditioning and the right answer far more often than households assume. Before spending on ducted, it is worth asking whether two or three well placed splits would do the job for a third of the money. Two or three well placed splits often do what a household actually needs. Model availability narrows sharply through summer months. Warranty registration is usually the owner's responsibility.

Capacity determines price more than brand does. A 2.5kW unit suited to a bedroom runs $1,100 to $1,800 installed, a 5kW unit for a living area $1,600 to $2,800, and a 7 to 8kW unit for a large open plan space $2,300 to $3,800. Those bands overlap between brands considerably, so a premium 5kW unit can cost the same as a budget 7kW one. A premium 5kW unit can cost what a budget 7kW one does. Drain pans on ducted units need periodic checking. Roof pitch determines how much cavity is usable.

Brand differences are real but narrower than marketing suggests. Daikin, Mitsubishi Electric, Fujitsu and Panasonic all make reliable inverter systems with good Victorian parts and service networks, and the gap between them matters less than installation quality does. A premium unit fitted badly will underperform a mid range unit fitted well every time. Parts availability through Victorian wholesalers matters more day to day than any specification difference. Service agent coverage in your area matters more than a specification sheet.

Inverter technology is now standard and worth understanding. Rather than switching fully on and off, an inverter compressor varies its speed to match demand, which holds the temperature steadier and uses considerably less power than an older fixed speed unit. Any system sold new in Victoria today will be an inverter model. A Victorian HVAC contractor answers this immediately. Circuit protection ratings come from the unit specification. Trade accounts give faster access to wholesaler stock.

Multi split systems make sense in specific circumstances rather than generally. Where a house needs three or four rooms conditioned but has nowhere sensible for multiple condensers, or where a body corporate restricts outdoor unit placement, running several heads from one condenser solves a genuine problem. The trade off is that a fault in the outdoor unit affects every room at once. Branch boxes add another component to the refrigeration circuit that can eventually fail. Body corporate rules on outdoor units frequently force the decision. One condenser is easier to get approved than three.

Placement of both units affects performance and neither is arbitrary. The indoor head wants a position that lets air circulate across the room rather than straight into a wall, and the outdoor condenser wants shade, airflow and distance from bedroom windows. An installer who walks the house before quoting is doing the job properly, and single room work sits under split system installation. Ordering early secures the specification you actually chose. Manufacturer accreditation affects the warranty available.

Ducted Reverse Cycle

Ducted reverse cycle is what most Melbourne households picture when they think about conditioning a whole house, and it is a substantial investment that repays careful specification. The difference between a well designed system and a poorly designed one is not visible until the first hot week. Record the answer beside the other quotes you have. Roof cavity depth and duct routing decide most of what a ducted system will cost you.

Pricing runs $9,000 to $16,000 for a typical three bedroom house and $13,000 to $25,000 for a larger home with multiple zones. Capacity, duct runs, the number of outlets and the zoning arrangement all feed into that. A single storey house with a generous roof cavity is considerably cheaper to duct than a two storey or a house with a shallow pitch. Inverter compressors modulate output rather than switching. Manufacturer training differs between brands considerably. Accredited installers access longer warranty terms.

Zoning is the feature that determines running cost more than anything else. Dividing the house into separately controlled areas means conditioning the living area during the day and the bedrooms overnight rather than the whole house continuously, which can halve the running cost. Four to six zones suits most family homes, and controls sit under thermostat and zone controller installation. Check the answer against a second installer. Beyond six zones the cost climbs faster than the benefit does.

Duct quality and insulation are where cheap systems cut corners invisibly. Ducting run through a Melbourne roof cavity experiences extreme temperatures in both directions, and thin insulation means conditioned air arrives at the outlet several degrees off what left the unit. Asking what R-value the ducting carries is a question few households think to ask. Efficiency ratings compare units of similar capacity only.

Ceiling versus underfloor placement depends on the house. Most Victorian homes use ceiling ducting because roof cavities are accessible, though older homes on stumps with limited roof space sometimes use underfloor systems. Underfloor delivers heat more effectively and cooling less effectively, which suits Melbourne's balance reasonably well. Older homes on stumps with shallow roof space are the usual candidates for underfloor. Lead times stretch during peak installation periods.

Bulkheads become necessary where there is not enough cavity depth for ducting, particularly in single storey homes with low pitched roofs and in apartments. A bulkhead is a boxed section of dropped ceiling concealing the duct run, and it is joinery work costing extra on top of the system. That work sits under bulkhead and pelmet installation. Seasonal figures describe real operation better than peak ones.

Evaporative Cooling

Evaporative cooling deserves an honest assessment because it suits Melbourne better than it suits most Australian cities, and it still leaves half the problem unsolved. Households considering it should understand both halves. Check whether that is already inside the quoted figure. Water consumption runs continuously while an evaporative system operates. Substitutions should be agreed rather than assumed.

The principle is simple and quite different from refrigerated air conditioning. Outside air is drawn through wet filter pads, which cools it as the water evaporates, and that cooled air is pushed through the house while windows stay open to let it out. There is no refrigerant, no compressor and no closed loop at all. Windows stay open so the air has somewhere to go.

Where it works, it works well and cheaply. Melbourne's hot days are frequently dry ones, with northerly winds bringing low humidity air down from the interior, and evaporative cooling performs strongly in exactly those conditions. Running costs are a fraction of refrigerated cooling because the only significant load is a fan and a water pump. Sound levels are published for every model sold here. Delivery access matters on upper floor installations.

Where it fails is during humid spells, and Melbourne gets those too. When a northerly swings around to a humid easterly or a summer storm approaches, the air already holds too much moisture for evaporation to cool it further, and the system delivers warm damp air. Those are precisely the nights households most want relief. A cool change usually breaks the pattern within a day.

The larger limitation is that it cannot heat. In a heating dominated climate, buying a cooling only system means keeping or installing a separate heating system, which is why households replacing ducted gas heating rarely choose evaporative. A reverse cycle system covers both from one installation. Photographs of the location settle this quickly. Older houses hide surprises above the ceiling. An installer should inspect the cavity before quoting ducted.

Water use and maintenance are the practical considerations. The system consumes water continuously while running, pads need replacing every few years, and the unit requires draining before winter to prevent damage. The unit needs draining before winter to prevent frost damage. At $3,500 to $7,000 installed it undercuts ducted reverse cycle substantially. Site protection covers floors during any installation.

Getting the Sizing Right

Sizing is where most air conditioning money is wasted in Victoria, and the error runs in both directions. Neither an undersized nor an oversized system can be fixed after installation without replacing it. Both are described below with what causes them. Wall brackets need masonry solid enough to carry the load.

Undersizing is the more obvious failure. A unit too small for the space runs continuously without reaching the set temperature, which is uncomfortable, expensive and hard on the compressor. It happens when an installer quotes to a price point rather than to the room. Neither problem is visible anywhere on a quote. Model numbers differ between similar looking units. Dimensions matter where wall space is limited.

Oversizing is less obvious and more common. A unit too large cools the air quickly then shuts off, cycling on and off repeatedly, which uses more power than steady operation and removes less humidity because the run times are too short. The room ends up cold and clammy rather than comfortable. Compressor wear accelerates alongside the extra consumption. Weatherproofing the penetration matters on exposed walls.

Floor area alone is not enough to size a system and any installer using it alone is guessing. Ceiling height changes the volume substantially, glazing area and orientation change the heat load enormously, insulation levels in ceiling and walls change how fast that load enters, and the number of people and appliances in the room adds to it. A west facing room with large windows needs far more capacity than a south facing room of the same size. Concrete pads keep a condenser clear of soil and debris.

As a rough starting point, Melbourne homes need roughly 130 to 160 watts per square metre for a well insulated room with modest glazing, rising above 200 watts for a poorly insulated room with large west facing windows. That is a sanity check rather than a calculation. A proper load assessment considers the whole envelope. Clearance dimensions appear in every installation manual. Filter driers are fitted whenever a circuit is opened. Service valves should stay accessible after installation.

Heating capacity deserves separate attention in this climate and rarely gets it. Manufacturer heating figures are quoted at an outdoor temperature of seven degrees, and Melbourne winter mornings routinely sit below that, with output falling as the temperature drops. Ask for the heating capacity at two degrees, and insulation improvements sit under ceiling and wall insulation installation. Output falls as the outdoor temperature drops below the rated condition. Return air paths need to stay clear of furniture.

Replacing Ducted Gas Heating

This is the decision facing more Victorian households than any other in this market, and it deserves its own section. Ducted gas was the Melbourne standard for decades and many systems are now failing. Refrigerant type on current equipment is generally R32. Compressor warranties often run longer than parts cover. Sound power and sound pressure are different measurements. Both figures appear on the product label.

Victoria has been moving deliberately away from gas in new residential construction, and that policy direction shapes the replacement market for existing homes as well. Households whose ducted gas heater has failed are increasingly comparing a like for like gas replacement against a ducted reverse cycle system that heats and cools. Current program details sit with the Victorian Government. Current program details are worth confirming before accepting a quote. Cable glands seal where wiring enters the outdoor unit. Terminal covers protect connections from moisture ingress.

Rebates and incentives are the first thing to check and they change periodically. Programs supporting efficient electric appliances have at various points offered substantial discounts on reverse cycle systems replacing gas heating, administered through accredited providers rather than claimed directly. The value can be significant enough to change which system you choose, so confirm what is current before accepting any quote. Wi-fi control ships as standard on many mid range units. Zone dampers are wired back to the central controller.

Existing ductwork can sometimes be reused and sometimes cannot. Gas ducted systems generally use ducting sized for the airflow of a gas furnace, which differs from what a reverse cycle system needs, and the ducting in a thirty year old system is often degraded regardless. An installer should inspect the existing ducting rather than assuming either way. Filter access varies between models and affects upkeep. Vacuum depth is measured with a gauge rather than guessed. Weighed charge follows the manufacturer specification exactly.

The running cost comparison has shifted considerably as gas prices have risen. A reverse cycle system delivers roughly three to five units of heat for each unit of electricity consumed, which is a fundamental advantage no gas appliance can match since combustion cannot exceed one to one. Combustion cannot exceed one to one, which no gas appliance can escape. Whether that means a lower bill depends on your tariff and any solar. Insulation displaced by other trades reduces efficiency.

Electrical capacity is the practical obstacle and it catches households out. Replacing gas heating with reverse cycle adds substantial electrical load, and older Melbourne switchboards frequently need upgrading at $800 to $2,500, with some larger systems requiring three phase supply. Have that assessed before committing, as covered under switchboard upgrade. Remote sensors help in awkwardly shaped living areas.

Running Costs

Running cost is where the real money sits over a system's life, and it varies far more with how you use the system than with which brand you bought. A few habits change the annual figure more than a star rating does. The main ones are set out below. Ceiling fans widen the comfortable range for very little. Drain lines need continuous fall to discharge properly. Condensate pumps add a component that can eventually fail.

A 5kW split system running four hours a day through a Melbourne summer costs $80 to $160 for the season, which surprises households who expect worse. Winter heating on the same unit costs more because the season is longer and the temperature difference greater, commonly $200 to $400 across the colder months. Reverse cycle heating remains among the cheapest ways to heat a room. Draught sealing improves any system's effectiveness cheaply. Rodents damage ductwork and wiring in roof spaces.

Ducted systems cost considerably more to run and zoning is what controls that. An unzoned ducted system conditioning an entire house continuously can run $600 to $1,200 a year, while the same system properly zoned to condition living areas by day and bedrooms by night frequently halves it. Zoning pays for itself faster than almost any other option. Window furnishings cut solar gain before conditioning starts. Balancing dampers set the airflow reaching each outlet. Grille throw patterns affect comfort in larger rooms.

Thermostat setting has more effect than most people realise. Each degree of additional cooling or heating adds roughly five to ten per cent to the running cost, so setting 24 degrees in summer rather than 21 makes a substantial difference across a season. Twenty four to twenty five in summer and eighteen to twenty in winter are the settings that balance comfort against cost. Those settings balance comfort against cost sensibly. Flexible duct sags where supports are inadequate.

Solar changes the arithmetic considerably for daytime cooling. Summer cooling load peaks in the middle of the day when a rooftop system is generating strongly, which means much of the cooling can run on self consumed generation rather than grid electricity. Winter heating peaks morning and evening when generation is weak, so the benefit is one sided, and panels sit under solar panel installation. External shading on west glass reduces the peak load sharply. Occupancy patterns shape which zones matter most. Glazing performance feeds directly into capacity selection.

Maintenance affects running cost more than households expect. Blocked filters force the system to work harder for less output, and a system that has lost refrigerant charge runs continuously without reaching temperature. Cleaning filters monthly during heavy use costs nothing, and servicing sits under air conditioning servicing. Return air sizing limits what a ducted system can deliver. Duct insulation ratings vary between suppliers.

Victorian Conditions

Four Victorian conditions affect what should be installed and none appears in national product literature. All four are worth raising before accepting a quote. Condensate drainage needs a fall and somewhere to discharge. Wall construction affects how the pipe penetration is made. A compliance certificate should follow any electrical work. Position any access panels before the ceiling is closed up.

The heating dominated climate is the first and it should drive the whole decision. Melbourne records substantially more heating degree days than cooling degree days, which means a reverse cycle system spends most of its operating hours heating. Specifying on cooling capacity alone, which is how systems are usually marketed, gets the priority backwards. Damper motors are the part most likely to need attention. Plenum boxes outlast the flexible duct attached to them.

Melbourne's summer pattern is the second and it explains why evaporative cooling persists here. Hot days frequently arrive on dry northerly winds carrying low humidity air, which is exactly what evaporative cooling handles well, and those spells break with a cool change rather than grinding on for weeks. Extended humid heat is less common here than in Sydney or Brisbane. Cool changes break most heatwaves within a few days. Setting the system back overnight reduces consumption noticeably. Room orientation determines the afternoon heat load.

Coastal salt air is the third and it attacks outdoor condensers directly. Properties along Port Phillip, Western Port, the Bellarine and the Surf Coast see corrosion of coil fins and cabinets, which shortens system life considerably, and suburbs from Frankston and Mordialloc round to Brighton and Williamstown are all affected. Manufacturers offer coastal or marine specification units with treated coils, and the premium is modest against replacing a condenser early. The premium for a coastal specification unit is modest against early replacement. Outlet count follows room count rather than floor area.

Regional temperature extremes are the fourth and they exceed Melbourne's in both directions. Mildura, Swan Hill and the Mallee run substantially hotter in summer, while Ballarat, Bendigo, the Macedon Ranges, the Dandenong Ranges and the alpine districts run much colder overnight in winter. Capacity suiting a Melbourne house may be inadequate in either setting. Ask a local installer what they specify for the district. Ceiling access hatches make future servicing far easier. Roof mounted condensers need a safe route for whoever attends.

Condenser placement raises two further Victorian considerations. Apartment and townhouse owners face owners corporation rules governing where outdoor units may sit and what noise they may make, and heritage overlay properties may face restrictions on units visible from the street. Both are worth checking before an installer arrives with equipment. Vibration isolation keeps a condenser quiet for neighbours.

Bushfire prone areas add a further consideration for outdoor equipment. Condensers sited against a wall in a designated area need care over ember accumulation and clearance from vegetation, and some households choose protective cages. Local guidance is worth seeking, and repairs generally sit under air conditioning repairs. Some households choose protective cages for exposed positions.

What Affects the Cost

Capacity and system type set the band, from $1,100 for a small split to $25,000 for a large zoned ducted system. Within each type the spread reflects capacity, efficiency rating and brand. Those bands overlap enough that a premium small system can cost what a budget larger one does. Controller placement affects how accurately it reads the room. Nitrogen purging during brazing keeps scale out of the pipework. Torque settings on flare joints prevent slow leaks developing.

Pipe run length is the most common variation on a split system quote. Advertised prices include three to five metres of refrigerant piping, and anything beyond that runs $60 to $120 per metre. A back to back installation is the cheapest possible arrangement and anything else costs more. Ductwork joins are where poorly built systems leak air.

Electrical work is the item households most often fail to budget for. Every system needs a dedicated circuit, older Melbourne switchboards frequently have no spare way, and an upgrade runs $800 to $2,500. Larger ducted systems sometimes require three phase supply. That is a substantially bigger piece of work again. Altitude affects performance in the alpine towns. Outdoor design temperature differs across Victorian districts.

Access and height affect the labour directly. Second storey indoor units, condensers requiring roof mounting or difficult ground positions, and houses with restricted side access all add hours and occasionally equipment hire. Send photographs of the intended locations with your enquiry. Restricted side access adds hours before anything is mounted.

Zoning and controls on a ducted system are a substantial line item and worth every dollar. Motorised zone dampers, a controller and the associated wiring add several thousand to a ducted installation while cutting running costs by around half. Skipping zoning to save on the install is a false economy. Roof cavity temperatures swing enormously through February. Anti vibration mounts reduce noise carried through the structure. Discharge air should not blow toward a neighbour's window.

Removal of an old system runs $150 to $400 including degassing, which must be performed by a licensed technician because refrigerant cannot lawfully be vented. Bulkhead work, condenser cages, concrete pads and brackets all sit outside base pricing too. Whole system swaps sit under air conditioning replacement and upgrade. Insulation levels change the load more than floor area does.

Melbourne and Regional Victorian Pricing

Rates hold reasonably steady across metropolitan Melbourne and the house explains far more of the variation than the postcode does. Access, switchboard condition and pipe run length account for most site differences. The tables below assume a standard installation with no electrical upgrade. Access and switchboard condition explain most of the rest.

Two features of Melbourne housing account for most of that spread. Inner suburban housing is predominantly older with dated switchboards, restricted side access and frequently no obvious condenser position, all of which add hours. Growth corridor housing through Werribee, Point Cook, Tarneit, Melton and Craigieburn is newer, with modern switchboards and generous roof cavities, which is faster to work and cheaper per installation. Both are about the housing stock rather than the postcode. Roof mounted condensers need a safe access route.

Regional pricing carries a travel component rather than a large equipment premium. Units are distributed through the same wholesalers statewide and the difference is mostly the installer's time getting to you. A local installer with other work booked in your district will usually beat one travelling from Melbourne. Country wholesalers carry narrower stock, so specific models may need ordering ahead.

Capacity requirements differ substantially in regional Victoria and that shows in the totals. Northern districts through Mildura and Swan Hill see sustained summer temperatures Melbourne rarely reaches, which justifies larger capacity, while the highlands and alpine areas need stronger heating performance at low outdoor temperatures. Northern districts justify larger capacity while the highlands need stronger heating output. Roof cavity temperature swings are extreme through summer.

Servicing access is worth weighing at the point of purchase rather than afterwards. A brand with a local service agent in your regional centre will be attended faster than one requiring a technician from Melbourne, and that matters when a system fails in a heatwave. Ask who services the brand locally before choosing it. Night setback saves more than most households assume. Hail damage to coil fins reduces output permanently.

Timing affects both price and waiting time more sharply than in most trades. Demand spikes with the first heatwave and again with the first cold snap, and installers are booked out for weeks at those points. Arranging installation in autumn or early spring usually gets a keener price and a faster start. Servicing intervals differ between ducted and split systems.

What to Look Out For

Confirm the installer holds a current refrigerant handling licence and that the electrical work will be done by a licensed electrician. Refrigerant work is licensed nationally through the Australian Refrigeration Council and electrical licensing is administered by Energy Safe Victoria. Ask for licence numbers rather than assurances. Coil cleaning restores output lost to accumulated dust. Airflow measurement confirms a ducted system performs as designed. Static pressure readings reveal restricted ductwork.

Establish exactly what the quoted price includes. A quote that lists inclusions and exclusions is worth more than a lower headline number. Mounting hardware should match the wall construction. Brackets, switchboard work and disposal of the old unit routinely sit outside the advertised number.

Ask how the system was sized and expect more than floor area in the answer. Ceiling height, glazing area and orientation, insulation levels and occupancy all affect the load, and an installer who has not asked about any of them is guessing. Both undersizing and oversizing cause problems that cannot be fixed later. External shading on west glass reduces peak load sharply.

Ask for the heating capacity at low outdoor temperature specifically. Manufacturer figures are usually quoted at seven degrees while Melbourne mornings sit below that, and output falls as it gets colder. In a heating dominated climate this is the number that matters most. Refrigerant loss shows as gradual decline rather than failure. Pollen ingress matters for households with allergies. Dust loading is heavier through the northern districts.

Check what rebates or incentives currently apply before accepting any quote. The value can change which system makes sense. Programs are claimed through accredited providers rather than directly. Three phase supply changes what larger systems can draw.

Have the switchboard assessed before committing to a ducted system. Older Melbourne boards frequently lack capacity for the additional load, an upgrade runs $800 to $2,500, and larger systems sometimes need three phase supply. Discovering that on installation day is the worst possible time. Hail damage to coil fins permanently reduces output. Roof mounted condensers need a safe way to reach them.

Get warranty terms and the licensing position in writing before any deposit. Manufacturer warranties frequently require installation by an accredited installer and regular servicing to remain valid. Contract requirements sit with Consumer Affairs Victoria, consumer guarantees with the ACCC, and disputes are heard at VCAT. Registration windows apply in the weeks after installation on several brands.

What to Look for in a Quote in VIC

An air conditioning quote worth comparing names the exact model and capacity, states the pipe run length included and the rate beyond it, confirms whether a dedicated circuit and any switchboard work are covered, specifies indoor and outdoor unit locations, states whether removal of an old system is included, gives the warranty terms, and lists exclusions. A single figure against the words split system installed tells you nothing. Ask for the exclusions listed as well. Compliance certificates follow any electrical alteration. Cable sizing follows run length as well as load.

Brief every installer with identical information so the numbers mean something. Provide the rooms to be conditioned with rough dimensions and ceiling heights, window sizes and orientations, the age of the house and its insulation if known, photographs of the proposed indoor and outdoor locations, switchboard photographs, and your suburb. Mention whether the property is a house, townhouse or apartment. Isolator switches must stay reachable without a ladder.

Four questions separate a careful installer from a cheap one. How did you size this system, what heating output does it deliver at two degrees, what is included beyond the base install, and what electrical work does the house need. Specific answers to all four indicate somebody doing the job properly. Condensate pans on ducted units want periodic checking. Vacuum and pressure testing precede charging the system.

Price two approaches against each other rather than two brands. Three well placed split systems against a ducted installation makes the real decision visible, since the ducted system costs several times more and delivers even temperatures throughout. Many households find splits do what they actually need. Seeing both figures makes the decision visible.

Budget the installation rather than the unit. Electrical work, additional piping, removal and any bulkhead or bracket work add fifteen to thirty per cent over an advertised price. Posting the job on The Quote Yard puts one brief in front of several Victorian installers, and system types sit under reverse cycle air conditioning. Electrical work and extras add fifteen to thirty per cent.
