Aircon Perth: Air Conditioning Installation
A reliable cooling system isn’t optional in Western Australia — it’s part of how a home or business stays liveable through summer. Whether you’re building new, renovating, or replacing a unit that’s reached the end of its working life, getting the installation right from the start makes a real difference to comfort, running costs, and how long the equipment lasts.
Our team designs and installs cooling systems for residential, commercial, and industrial properties across the metro area. We don’t believe in one-size-fits-all solutions. Every property has its own layout, sun exposure, insulation level, and usage pattern, and the system we recommend is based on those specifics rather than a standard package.
Why Installation Quality Matters
A poorly sized or badly installed unit causes more problems than people expect. Undersized equipment runs constantly and still can’t keep up on the hottest days. Oversized equipment cycles on and off too quickly, which wastes energy and wears components out faster. Incorrect duct placement or refrigerant line installation can lead to uneven cooling, strange noises, or leaks that show up months down the track.
Getting it right the first time means calculating heat load properly, choosing equipment that matches the space, and installing it to manufacturer specifications and Australian standards. It’s a step that’s easy to skip when a job is rushed, and it’s usually the reason a system that should last fifteen years starts having problems after three.
Types of Systems We Install
A split system is the most common choice for single rooms, smaller homes, or properties where ducted infrastructure isn't practical. It's a cost-effective option that's quick to install and easy to control room by room. We help clients choose the right capacity and the right indoor unit placement to get even airflow without an oversized footprint on the wall.
For whole-home or whole-building climate control, a ducted reverse-cycle setup offers consistent temperatures across multiple rooms or zones, controlled from a single point. This is a popular option for new builds and major renovations, where ductwork can be planned into the build from the start rather than retrofitted later. Zoning lets different areas of a property be heated or cooled independently, which helps manage running costs in larger homes.
A multi-head setup connects several indoor units to a single outdoor condenser, which suits properties that need cooling in multiple rooms but don't have the ceiling space or budget for full ducting. It's a middle-ground solution that still gives room-by-room control.
Offices, retail spaces, warehouses, and hospitality venues each have different cooling demands based on occupancy, equipment heat load, and how the space is used throughout the day. We design commercial installations around those practical realities, working with business owners and facility managers to minimise disruption during the install.
For larger properties needing high-capacity cooling without the energy demands of older systems, ducted refrigerated options offer efficient performance with the flexibility of zoned control.
Our Installation Process
Magna aliquip sunt pariatur reprehenderit aliqua culpa dolor sunt elit anim veniam. Labore quis minim sit voluptate temp.
We start with a site visit to assess room sizes, ceiling access, insulation, window orientation, and existing electrical infrastructure. This is where we calculate the actual cooling load rather than guessing at a unit size.
Based on that assessment, we recommend equipment suited to the property and budget, explaining the trade-offs between options like split systems versus ducted setups, and standard versus higher-efficiency units.
We provide a clear, itemised quote before any work begins, covering equipment, installation labour, and any additional work such as electrical upgrades or ductwork.
Our licensed technicians handle the full installation, including mounting, refrigerant line work, electrical connection, and commissioning, finished to manufacturer specifications and Australian Standards.
Once installed, we test the system fully, walk through the controls, and make sure everything is running as expected before we consider the job done.
New Builds and Renovations
If you’re building a new home or undertaking a major renovation, the best time to plan cooling infrastructure is before walls and ceilings are closed up. We work directly with builders, architects, and homeowners during the design and construction phase to plan ductwork, zoning, and unit placement properly, which avoids costly retrofitting and gives better long-term performance.
Comfort Starts With The Right System
From installation and repairs to ongoing maintenance, we provide reliable heating, ventilation and air conditioning solutions designed for Perth homes and businesses.
Replacing an Existing System
If an existing unit is no longer cooling effectively, has become noisy, or is simply old enough that running costs have crept up, replacement is often more cost-effective than repeated repairs. We can assess whether your current system is worth repairing or whether a replacement would pay for itself in lower energy bills and fewer breakdowns.
Servicing Homes and Businesses Across the Region
From coastal suburbs to the Hills and everywhere in between, our installation team covers the metro area. We’ve worked on single-room split system installs in established homes, full ducted systems in new builds, and multi-zone commercial fitouts, giving us a broad base of experience to draw on regardless of property type or scale.
Why Choose HVAC Perth
We offer end-to-end HVAC services for residential, commercial, and industrial clients across Perth.
We calculate heat load properly rather than estimating, which means better comfort and lower running costs over the system's lifetime.
We'll tell you if a cheaper option suits your needs just as well as a premium one, and we won't oversell capacity you don't need.
Every installation is completed by qualified tradespeople to manufacturer specifications and Australian Standards.
Our quotes are itemised and explained clearly, with no surprise charges once work begins.
We're available for servicing, maintenance, and repairs long after the install is complete, so you're not left without support down the track.

Frequently Asked Questions
Cost depends on the type of system, the size of the property, and how much additional work is needed (such as electrical upgrades or ductwork). A single split system is generally the most affordable option, while ducted reverse-cycle setups cost more upfront but cover larger areas with zoned control. We provide a free, itemised quote after assessing your property so you know exactly what’s involved before committing.
A standard split system install is usually completed in a few hours. Ducted systems take longer, typically one to three days depending on the size of the property and the complexity of the ductwork. For new builds, installation is generally staged across the construction timeline rather than completed in one visit.
The right size depends on room dimensions, ceiling height, insulation, window orientation, and how the space is used. Rather than relying on rough rules of thumb, we calculate the actual heat load for your property during a site assessment, which gives a far more accurate recommendation than sizing based on floor area alone.
Split systems suit single rooms or smaller properties and are generally more affordable to install. Ducted systems suit whole-home or whole-building cooling and offer a cleaner aesthetic with no visible indoor units, but involve a higher upfront cost. The right choice depends on your property layout, budget, and whether you need zoned control across multiple rooms.
Most residential split system and ducted installations don’t require council approval, though some strata properties, heritage-listed buildings, or larger commercial projects may have additional requirements. We can advise on this during your initial assessment and handle any necessary documentation as part of the job.
We recommend a service at least once a year, ideally before the start of summer, to keep the system running efficiently and to catch minor issues before they become costly repairs. Commercial systems with heavier use may benefit from more frequent servicing.
Yes. Split systems and multi-head setups are well suited to older homes without existing ductwork, since they don’t require ceiling space for ducting. Ducted systems can still be retrofitted into older homes, though it usually involves more invasive work to run ductwork through ceiling cavities.
We work with a range of established, reputable brands and will recommend equipment based on your budget, property requirements, and warranty preferences, rather than pushing a single brand across every job.
