Air Conditioning System Supplier in Perth metropolitan
An air conditioning system supplier sells and usually arranges installation of cooling and heating equipment: split systems, multi-head splits, ducted refrigerated units, and evaporative systems suited to Perth's hot, dry summers. Some suppliers stock a single brand and run their own installation crews. Others act as agents for several manufacturers and subcontract the fit-out. Either way, the supplier is your first point of contact for sizing the system to your home, quoting the job, and standing behind the product if something goes wrong.
With 342 businesses in this category across the Perth metro area, the range runs from small local operators who mainly service split systems to larger firms that handle whole-house ducted refrigerated jobs in new builds and renovations. Getting a fair comparison between them isn't always easy, because quotes can vary by brand, unit capacity, ductwork complexity, and whether electrical work is included.
When you're comparing suppliers, look for a proper load calculation rather than a rough guess based on room size, a clear breakdown of what's included (unit, install, electrical, warranty, any ducting or roof work), and licensing for both the refrigerant handling and electrical components of the job. Ask how they handle warranty claims and callbacks, since that's where the difference between suppliers usually shows up years after installation, not on install day.
Our scoring looks at how businesses in this category are reviewed over time, how consistently they respond to jobs, and other public signals of reliability, so you can shortlist suppliers worth getting a quote from rather than starting from scratch.

Common questions about air conditioning system supplier
- How much does a new air conditioning system cost in Perth?
- A single split system for one room typically runs from around $1,500 to $3,500 installed, depending on capacity and brand. Ducted refrigerated systems for a full home are a bigger job, often anywhere from $8,000 to $20,000 or more, depending on house size, number of zones, and ductwork access. Evaporative systems generally sit below refrigerated ducted options but cost more to run efficiently in humid weather. Always get an itemised quote so you know what's covered.
- How often does an air conditioning system need to be replaced?
- Most residential systems last 10 to 15 years with regular servicing, though compressors and outdoor units in Perth's heat can wear faster if the system is undersized or run hard through summer. Annual servicing (cleaning filters, checking refrigerant, inspecting the outdoor unit) extends the working life and is usually cheaper than emergency repairs.
- What should I expect during the quoting and installation process?
- A reputable supplier will visit or ask detailed questions about room sizes, ceiling height, insulation, and sun exposure before quoting, rather than pricing off a phone call alone. Expect a written quote covering the unit, installation labour, any electrical upgrades, and warranty terms. Installation for a single split system usually takes half a day; ducted systems can take several days depending on roof access and zoning.
- How can I judge whether a supplier does good quality work?
- Check whether they're licensed for both refrigerant handling (required under Australian law) and electrical work, or whether they use a licensed electrician for that part. Ask how they handle warranty issues after install, since call-back response is often the clearest sign of a supplier that stands behind its work rather than one that disappears once the invoice is paid.
