How a Relocation Actually Works

The job starts with the refrigerant. On a working split system, the technician runs it in cooling mode and pumps the refrigerant back into the outdoor unit, closing the service valves so the gas stays trapped there. Where the system is not running, or the charge is uncertain, the gas is recovered into a cylinder instead. Either way, this must be done by someone holding a refrigerant handling licence from the Australian Refrigeration Council. Releasing refrigerant to the air is illegal and harms the environment.

Next comes the power. The electrical supply is isolated and disconnected, which is electrical work and needs a licensed electrician, although many air conditioning technicians hold both licences.

Then the units come off. The indoor head unhooks from its wall bracket, the outdoor unit is lifted off its feet or brackets, and the old pipework, drain and cable are removed or cut back.

At the new location, a fresh bracket goes up, a new wall penetration is cored, and pipework, cable and condensate drain are run to suit. Flares are made on the new pipe ends and the connections are tightened to the correct torque, because a poorly made flare is one of the most common causes of slow leaks later.

Commissioning finishes it. The pipework is pressure tested with nitrogen, evacuated with a vacuum pump to remove air and moisture, and then the refrigerant is released back into the system. Extra refrigerant is added if the new pipe run is longer than the unit's pre charged length. A final check of pressures, temperatures and drain flow confirms the system works. Most businesses offering air conditioning installation also do relocations.

Pipework, Refrigerant and Why Old Pipe Is Often Replaced

Reusing existing pipework sounds sensible. Sometimes it works, particularly on a short move where the old run can be extended with properly brazed joints. More often the technician replaces it. The old pipe may be the wrong length for the new position, it may have been bent and kinked during removal, and its flared ends have to be cut off and remade regardless. On older systems, pipework that has sat in the sun for years can have cracked insulation that lets condensation form.

Length matters for another reason. Every split system comes pre charged with enough refrigerant for a set length of pipe, commonly somewhere between five and ten metres, and runs longer than that need extra gas added by weight.

Each model also has a maximum pipe length and a maximum height difference between the indoor and outdoor units. Exceeding them reduces performance and can damage the compressor.

A good technician will measure the new run before quoting. Ask what length they have allowed for and whether extra refrigerant is included.

Top ups outside a relocation fall under air conditioning regassing. The condensate drain also needs a continuous fall to its outlet, since a drain that sags or runs uphill will back up and leak down the wall.

Choosing the New Position

Start with the indoor unit. It should sit high on a wall with a clear throw across the room, away from direct sun and not blowing straight onto a bed or couch. It also needs a practical path for pipe and drain to reach the outside. An internal wall with no easy route out is often a poor choice even if it looks best.

The outdoor unit needs shade, airflow and access. Keep it away from bedroom windows, including the neighbour's.

Leave clearance for servicing. Think about where the condensate and defrost water will go, as in winter a reverse cycle unit sheds water from the outdoor coil too.

Renovations are the other big driver. Extensions frequently land on top of where the old outdoor unit sat, and new decks, pergolas and pools do the same. Planning the relocation into the renovation, with pipework run before walls are lined, is far tidier and cheaper than moving it afterwards. Raise the air conditioner at the design stage of any home extensions.

Moving a Unit That Never Worked Well Where It Was

Plenty of relocations are about comfort. A split system mounted in the wrong spot can run all afternoon and still leave half the room warm, and the fix is often a better position rather than a bigger unit. Indoor units need a clear path to throw air across the room, so a head tucked into a corner of a long open plan living area, or mounted above a doorway facing the wrong way, struggles to reach the far end. Units that blow straight onto a bed or a couch make people turn them down or off, which defeats the purpose. The sensor that decides when the room is cool sits in the indoor head itself, so a unit catching direct afternoon sun through a window, or placed near a kitchen, can switch off before the rest of the room has cooled.

Before relocating for comfort, stand in the room on a hot afternoon and notice where the heat actually builds up. West facing glass, a skylight and an uninsulated section of ceiling are common culprits. Positioning the indoor unit to throw air toward those areas usually improves comfort more than moving it anywhere else. It is also worth checking the capacity. A unit that was undersized for the room when installed will still be undersized in a new position, and a technician can calculate the load for the room before any work starts. Where the room has grown through an extension, a larger unit or a second head may be the honest answer.

Noise and Neighbours

Noise is one of the most common reasons Adelaide homeowners move an outdoor unit. The compressor and fan produce a steady hum that carries further at night, when background noise drops, and a unit mounted on a boundary fence or under a neighbour's bedroom window can cause a genuine dispute. Mounting on a wall can also transmit vibration into the building, so rubber mounts and a solid base matter. EPA SA publishes guidance on noise from domestic air conditioners and heat pumps, and local councils handle neighbour complaints. Read the guidance from EPA SA before choosing a new position, so the move actually fixes the problem.

Newer units are much quieter than older ones. Where a fifteen year old outdoor unit is the source of complaints, replacing it may solve the noise problem more effectively than moving it. Acoustic screens and enclosures also exist, provided they leave the airflow the unit needs. Where the unit cannot move far, soundproofing installation in the nearest rooms can help.

Moving a Ducted Outdoor Unit

Ducted systems usually have only one thing that moves easily, and that is the outdoor unit. The indoor fan coil sits in the roof space connected to every duct in the house, so moving it means redesigning the ductwork, which is closer to a new installation than a relocation. Outdoor units are another matter. They can typically be moved to a new position around the house at $800 to $2,500, depending on the distance, the pipe size and whether the electrical supply needs upgrading.

Ducted pipework is larger and the refrigerant charge heavier. Longer runs need more gas. The unit is also far heavier than a split system condenser, so the new base has to be solid and level. Ducted systems approaching fifteen years deserve the relocate or replace comparison before any money is spent. Replacement guidance for older systems sits alongside new ducted air conditioning options.

Multi Split and Cassette Systems

Multi split systems run two or more indoor units from one outdoor unit, and moving any part of them is more involved than moving a single split. Each indoor head has its own pipe pair and cable back to the outdoor unit. Relocating one head changes the total pipe length on the system, and the refrigerant charge has to be recalculated for the whole installation rather than for that one run. Manufacturers also set limits on the combined pipe length and on the length to any single head, so a move that looks simple on paper may push the system past its design.

Moving the outdoor unit of a multi split affects every head at once. All the pipe runs need extending or replacing, and the job usually costs more than an equivalent single split move. Ask the technician to record the revised refrigerant charge for the whole system on the invoice, which helps anyone servicing it later.

Ceiling cassettes bring the roof space into play. The unit hangs from the framing above, with pipework, drain and power running through the ceiling, and a new position means a new opening in the plaster, new supports and patching the old hole. Cassettes also rely on a pumped or gravity drain that has to be rerouted carefully. Many owners find that a renovation needing a cassette to move is a good moment to reconsider the layout altogether, and cassette air conditioning installers can advise whether a new position or a different system suits the new room better.

Approvals, Heritage and Strata

Most relocations at a house need no approval. The exceptions are worth knowing though. Heritage properties and homes in historic areas may face limits on units visible from the street, and some positions near boundaries or on front facades can fall outside the usual exemptions. Check through PlanSA or with the council if the new position is prominent.

Apartments are different. The strata or community corporation usually controls external walls and balconies, and approval is typically needed before an outdoor unit moves. By laws can dictate appearance, noise limits and where condensate drains. Where an existing position has caused complaints, an independent strata inspection can help settle the dispute.

Regional Considerations Across South Australia

Older Adelaide homes in suburbs such as Norwood, Unley and Prospect often have soft sandstone, bluestone or old brick walls that need careful drilling and suitable fixings for new brackets. Coring through them takes time. Patching the old holes neatly in heritage masonry is its own skill, and the old penetrations should always be sealed against weather and pests.

Coastal suburbs expose outdoor units to salt, so relocation is a chance to move a unit away from the most exposed side of the house. Northern and inland suburbs see higher summer peaks, making shade for the new position more valuable. The Adelaide Hills lean on reverse cycle heating in winter, where defrost water from the outdoor unit can freeze on paths and steps. Regional towns have fewer technicians and longer travel times, which is worth factoring into the quote. Old penetrations in masonry homes are best finished with proper brick repair.

What Can Go Wrong After a Relocation

Most relocations go smoothly, but a few problems show up days or weeks later, and knowing the signs helps you raise them while the workmanship warranty still applies. A slow refrigerant leak at a poorly made flare is the most common. The system cools well at first, then gradually weakens over a month or two as the charge escapes. Ice forming on the pipework at the outdoor unit, or a hissing sound near the connections, points the same way. Oily marks around a flare nut are another clue, as refrigerant carries a little compressor oil out with it when it escapes.

Moisture left in the system causes a different kind of trouble. When the pipework is not evacuated properly before the refrigerant is released, air and water vapour stay inside, reducing performance and, over time, damaging the compressor. You cannot see this from outside, which is why asking for the vacuum and pressure test to be recorded on the invoice is worthwhile.

Water running down the inside wall below the indoor unit usually means the drain has been installed with too little fall, has a kink, or has come loose inside the wall. Humming or rattling that was not there before often comes from a bracket fixed to a hollow wall or an outdoor unit sitting without anti vibration pads. Error codes on start up can trace back to a loose or incorrectly terminated interconnecting cable. All of these should be fixed at no cost if the fault lies with the relocation work.

Ask the technician before they leave what workmanship warranty applies and for how long. Keep the invoice showing the date, the work done and any refrigerant added. If a problem appears, report it promptly in writing.

Timing, Access and the Day of the Move

A short split system move on a single storey home usually takes two to four hours. Moving an indoor unit to another room with a new pipe run, or relocating a ducted outdoor unit, can take most of a day, and a second storey wall or a roof mounted unit may need extra hands or a scaffold. Spring and autumn are the easiest times to book. Summer brings breakdowns that push relocations down the queue, and in a heatwave most technicians give priority to homes without cooling.

Power to the air conditioning circuit will be off during the work, and some jobs need the whole house isolated briefly. Clear the area under the indoor unit and around both the old and new outdoor positions. Keep pets away from the work area, because open wall penetrations and power tools do not mix with curious dogs. Make sure the technician can reach the roof space if pipework needs to run through it. Mention any tight side access, locked gates or steep driveways when booking, because a heavy outdoor unit often has to be carried by two people.

Expect some mess. Coring through brick or stone throws dust, and the old indoor position leaves bracket holes and a pipe penetration to fill. Ask whether patching is included and whether the patch will be ready to paint. Matching paint to an older wall is often the owner's job, and colour matching old walls is routine work for interior house painting businesses.

Rentals and Tenants

Anyone renting should not move an installed air conditioner without the landlord's written agreement, because the system is part of the premises. Where a unit is badly placed or noisy, raise it with the landlord or property manager, who can decide whether a relocation is worthwhile. Tenancy rights and obligations in South Australia are administered by Consumer and Business Services. A tenant who installs their own unit with the landlord's permission should agree in writing, before any work starts, whether it stays or goes at the end of the lease and who pays to make good the walls afterwards. Landlords weighing a relocation against replacement should factor in the age of the unit and whether a new, quieter model would avoid future complaints altogether.

What AC Relocation Costs in SA

A short move on a split system, such as shifting the indoor unit along the same wall, usually costs $400 to $900. Moving the indoor unit to another room runs $700 to $1,500 because it needs new pipework and often a new circuit. Moving just the outdoor unit costs $400 to $1,200. Ducted outdoor units run $800 to $2,500, reflecting the heavier unit and larger pipework.

Removing a system and refitting it at a new house typically lands between $900 and $2,000 per split system. Extra refrigerant for longer runs adds $80 to $300. Patching old penetrations costs $150 to $500 depending on the wall. A new electrical circuit runs $300 to $900, and older switchboards may also need switchboard upgrades.

What to Look Out For

Make sure the refrigerant is being recovered or pumped down by an ARC licensed technician. Anyone who suggests simply cutting the pipes is venting gas illegally. Ask whether the pipework is new or reused and what length has been allowed. Check the quote includes vacuuming and pressure testing, because skipping them leads to leaks and moisture in the system.

Think hard before moving an older or R22 system, because the move may cost most of what a new unit would. Check the contract of sale before taking a system to a new house. Get strata approval first in an apartment. Consumer guarantees on the work are explained by the ACCC, and disputes that cannot be resolved directly can go to SACAT.

How to Get Useful Quotes

Give the brand, model and age of the system, and say whether it is a split, multi split or ducted system. Describe which unit is moving and roughly how far. Photos of the current position and the new one help a lot. Say why you are moving it, whether renovation, noise, solar or moving house, since the reason often changes the best answer.

Mention the wall type at the new position, such as brick veneer, double brick, stone or weatherboard. Say whether the home is heritage listed or part of a strata scheme. Have each quote confirm refrigerant recovery, new or reused pipework, extra gas, electrical work, patching of old holes and the warranty on the relocation. Smaller units that plug in may need powerpoint and light switch installation, which can be booked alongside.
