Oakleigh Split System Installation by a Licensed Technician
Pergz Air provides split system installation in Oakleigh for residential and commercial properties throughout the area. Oakleigh’s housing stock is a mix of post-war brick veneer homes, older weatherboard cottages, and established strata units — many with narrow roof cavities, ageing electrical infrastructure, and limited wall penetration options. We know what these properties demand and we plan every installation accordingly, from sizing the unit correctly to routing pipe runs cleanly through walls that weren’t designed with air conditioning in mind. Licensed, local, and straightforward to deal with.

Why Oakleigh Homes Suit Split Systems
Oakleigh’s established character properties often make ducted systems impractical — limited ceiling space, original cornicing worth preserving, and older slab-on-ground construction all point toward split systems as the right fit. A reverse cycle split system delivers both heating and cooling from a single unit, which matters in Melbourne’s climate where a 38-degree January afternoon can be followed by a 12-degree July morning. For a suburb full of homes built in the 1950s through 1980s, split systems offer a practical upgrade that doesn’t require major structural work.
Single Head Split System Installation in Oakleigh
One indoor unit paired with one outdoor compressor — the most cost-effective way to bring reliable climate control to a bedroom, lounge room, or open-plan living area in an Oakleigh home. Single head systems are particularly well-suited to rental properties and owner-occupier homes where one primary living space needs sorting first, with the option to expand later. If you’re a property manager needing a documented, reliable installation for a tenant complaint or end-of-lease upgrade, a single head system installed by a licensed technician gives you a clear paper trail and a unit that performs consistently.
How We Handle the Installation
We begin with a proper assessment of the room and the property — wall construction, pipe routing options, proximity to the switchboard, and any constraints specific to older Oakleigh homes like double-brick walls or original timber framing. We calculate the right system capacity for the space, select a unit that suits the budget and the building, then install everything neatly with pipe runs concealed where the structure allows. Most single head installations in Oakleigh are completed within a half-day, leaving the property tidy and the system ready to run.
Multi Head Split System Installation Oakleigh
Multiple indoor units running off a single outdoor compressor, with each room independently controlled. For an Oakleigh property where you want the bedroom, lounge, and study all climate-controlled without three separate outdoor units cluttering the side of the house, a multi head system is the practical answer. Strata managers and property owners with older buildings particularly benefit here — one outdoor unit means one penetration point, less visual impact on the exterior, and a simpler compliance footprint when dealing with owners corporations or council requirements.
Our Multi Head Installation Approach in Oakleigh
Every multi head installation starts with a design stage. We work out which indoor units are needed, size each one to its room, then select an outdoor unit with the correct total capacity to support all connected heads without compromise. For Oakleigh’s established properties, we pay close attention to pipe routing — older homes often have limited eave space and original render that needs to be worked around carefully. We manage the full scope from design through to commissioning, and we provide documentation suitable for strata records or property management files.
Choosing the Right System for Your Oakleigh Property
Single head, multi head, or ducted — here’s how to think about which fits your situation.
Single Head
The right choice for one room or one defined area. Affordable, fast to install, and highly effective when sized correctly for the space. Ideal for Oakleigh rentals or homes where one room is the priority.
Multi Head
The better option when two or more rooms need independent climate control and you want to keep the number of outdoor units to a minimum — particularly relevant for Oakleigh strata properties and period homes where exterior aesthetics matter.
Ducted
A whole-home solution with all pipework and ductwork concealed in the ceiling cavity. Higher upfront investment, but the most seamless result for larger Oakleigh homes where ceiling access is available and consistent whole-home comfort is the goal.

Why Choose Pergz Air for Split System Installation in Oakleigh

Licensed Refrigeration Technician
Every Oakleigh installation is carried out by a fully licensed refrigeration technician — not a subcontractor handed the job on the day. For property managers who need compliant, documented work, that distinction matters.

Correct Sizing for Older Properties
Older Oakleigh homes often have higher ceilings, poor insulation, and single-glazed windows that affect load calculations significantly. We do the numbers properly before recommending any unit, so you’re not paying to run an undersized system that can’t keep up.

Careful Pipe Routing
Period homes and brick veneer properties in Oakleigh require more thought around pipe runs — original render, narrow eaves, and double-brick walls all affect how a clean installation comes together. We plan the routing before we drill anything.

Transparent, Fixed Pricing
You receive a clear written quote before any work begins. If a property assessment reveals complications — an ageing switchboard, a difficult penetration point — we tell you upfront, not after the job is done.

Melbourne-Based, Oakleigh-Familiar
We service Oakleigh and the surrounding suburbs regularly and understand the local building stock. You deal directly with Pergz Air from first contact through to sign-off — no call centres, no handoffs.
Split System Installation Oakleigh — Common Questions
How long does a split system installation take in Oakleigh?
A single head installation in Oakleigh typically takes between two and four hours. Older properties with double-brick walls or limited eave access can add time to the pipe routing stage, which we flag during the initial assessment. Multi head systems take longer depending on the number of indoor units and the complexity of the pipe runs through the building.
What size split system do I need for an Oakleigh home?
Sizing depends on room dimensions, ceiling height, insulation quality, window area, and aspect. Oakleigh’s older homes frequently have higher ceilings and single-glazed windows, both of which increase the heating and cooling load compared to a modern home of the same floor area. We calculate capacity properly during your quote rather than relying on a rough rule of thumb.
Do split systems handle Oakleigh winters effectively?
Yes. Modern reverse cycle split systems extract heat from outside air even when temperatures drop to around 5–7°C, which covers the vast majority of Oakleigh winter nights. They’re a genuinely practical year-round solution rather than a cooling-only appliance.
Can you install a split system in an older Oakleigh brick home?
In most cases yes, though older brick construction does require more planning around pipe penetrations and routing. Double-brick walls need core-drilling rather than standard drilling, and the outdoor unit placement needs to account for the building’s structure. We assess all of this during the site visit and won’t proceed until we have a clean installation path mapped out. If you’d like to see how we approach similar properties nearby, our Bentleigh and Bentleigh East pages cover comparable housing types.
How much does split system installation cost in Oakleigh?
Cost varies based on the unit selected, the number of heads, and the complexity of the installation — particularly relevant in older Oakleigh properties where pipe routing or switchboard proximity can affect the scope. Get in touch for a free, no-obligation quote specific to your property and we’ll give you a clear figure before anything is booked.
How often should an Oakleigh split system be serviced?
Once per year is the standard recommendation to maintain efficiency and catch developing faults before they become costly. For rental properties in Oakleigh, annual servicing also provides documented maintenance records that support landlord compliance obligations.
