Perth summers regularly bring runs of days above 35 degrees, and suburbs away from the coast miss out on much of the relief the Fremantle Doctor sea breeze brings in the afternoon. That makes cooling a serious purchase for most households, and choosing among the air conditioning companies Perth has to offer is worth some care.
Perth homes use three main types of system. Ducted evaporative cooling is common in older homes because it works well in dry heat and is cheap to run, ducted reverse cycle systems heat and cool the whole house, and split systems suit single rooms or smaller homes. A good installer will explain which type suits your home rather than steering you to one product.
We checked each business below on its own website for a Perth base, the systems it installs and any licences it displays. ARCtick licence numbers are only mentioned where the company shows them. For other trades and home services, see our Perth hub.

Best Air Conditioning Companies In Perth
1. Mouritz — Willetton Air Conditioning Specialist With Three Perth Locations
Mouritz has its main office and showroom at 11 Yampi Way in Willetton, a second showroom in Wangara and an office in Midland, which gives it coverage north, south and east of the city. The company says it has been in business for more than 40 years. It installs reverse cycle split systems, ducted evaporative cooling, ducted refrigerated air conditioning and ducted gas heating for homes, and it also works on offices, factories, shops, hospitality venues and schools.
Its brand range is wide, from Actron, Daikin and Fujitsu to Breezair, Braemar, CoolBreeze and Brivis, so it can quote on nearly any system type. Mouritz lists dealer awards including Fujitsu number one WA dealer across many years and Bonaire number one WA dealer, and its site links to ARCtick. It also handles servicing, repairs and upgrades, and offers finance through a third-party provider. It suits homeowners who want to see units in a showroom and compare evaporative against reverse cycle before deciding.
2. Ford & Doonan — WA Reverse Cycle Network Operating Since 1985
Ford & Doonan says it has been a WA air conditioning name since 1985, growing from one small Perth workshop. Its head office is in Kardinya, and it lists stores in Joondalup, West Perth, Clarkson, Canning Vale, Osborne Park, Midland, Malaga, Victoria Park and Mandurah, plus Bunbury and Busselton. The business focuses on ducted reverse cycle systems, split and multi-split systems and ceiling cassettes, with Daikin, Panasonic, Samsung and Rinnai among its brands.
A useful service for older Perth homes is its evaporative to reverse cycle replacement, along with ducted system replacements and air diverters. It also runs a builders direct program for new homes, commercial servicing and maintenance, and recommends at least one service a year. The company states it won the HIA Western Australia Customer Service award in 2024 and 2025. The business also offers franchise opportunities, so ask which store will handle your job. It suits households switching from evaporative to reverse cycle.
ACSIS Airconditioning is based at 2/145 Rockingham Road in Hamilton Hill and describes itself as family run and owned. It says it began in 1999 and calls itself one of Western Australia’s largest Daikin retailers. Its site displays ARCtick licence AU 27248 and states that its technicians are fully licensed and qualified. The company supplies and installs ducted systems, split and multi-split systems, ceiling cassettes, zone controllers and air purifiers for homes and commercial premises.
As well as Daikin, ACSIS lists Panasonic, Mitsubishi and Samsung, and it provides after-sales support. It does not mention evaporative cooling, so it is better suited to buyers who have already decided on reverse cycle. A published ARCtick number makes it easy to confirm that refrigerant work will be done by licensed people. A Hamilton Hill base is handy for Fremantle, Cockburn, Melville and the wider southern suburbs. It suits households and small businesses wanting a long-running family dealer for Daikin systems.
Wanneroo Gas & Air Centre is based at 2/8 Baretta Road in Wangara and says it has been cooling and heating Perth homes since 1972. It describes itself as a small, independent company where every step of the job, from the initial quote to installation, is done by its own team. It installs ducted air conditioning, evaporative air conditioning and split systems, and it is a specialist dealer for Panasonic cooling and heating products.
Gas heating is a strong second line. The company installs ducted gas heating and repairs gas heaters, and at the time of checking it advertised a flat fee for portable gas heater repairs. That combination is practical for northern suburbs homes that run evaporative cooling in summer and gas heating in winter. Office hours are weekdays only. The site does not show an ARCtick number, so ask for it when you get a quote. It suits households in Wanneroo, Joondalup and surrounding suburbs who want a long-established local business.
Jarrahdale Heating & Cooling has its showroom at 10 Malcolm Road in Maddington and describes itself as a local, family-owned business. It has made and supplied slow combustion wood heaters since 1981 and says it has been installing air conditioning in WA homes for more than 25 years. Its cooling range covers ducted reverse cycle, ducted evaporative and wall split systems, along with replacement units, smart controls, servicing and repairs.
Brands include Fujitsu, Daikin, Haier and Braemar for refrigerated systems, and Coolair, Breezair and Braemar for evaporative cooling. The company also sells gas log fireplaces and describes itself as WA’s exclusive dealer for Archer. Air conditioning is offered as a turnkey service from design through to aftercare, and the site advertises interest-free finance on air conditioning. It suits homes in the hills and eastern suburbs, such as Kalamunda, Gosnells and Armadale, that want cooling and winter heating from one supplier.
6. Langler Air — Balcatta Mitsubishi Electric Diamond Dealer Installing Since 1995
Langler Air operates from an office and warehouse at Shop 2, 3 Cressall Road in Balcatta and says it has installed air conditioning in Perth since 1995. It describes itself as a Mitsubishi Electric Diamond Dealer and also lists Daikin and Rinnai. Its work covers ducted, split system and reverse cycle installations, smart air conditioners, upgrades and system removals, for residential and commercial clients.
The business is clear about what it does not do. It only performs supply and install work and does not offer maintenance, and its Balcatta site is not a showroom. Evaporative cooling is not listed either. That focus can be an advantage if you simply want a new reverse cycle system installed by a team that does nothing else, but you will need a separate business for future servicing. Its specialists are described as trained and licensed. It suits buyers who know which system they want and are comparing installation quotes.
7. All Air Services — Wangara Installer For Repairs, Servicing And Commercial VRF
All Air Services is based at 2/1 Opportunity Street in Wangara and says it has helped homes and businesses with heating and cooling for more than a decade. It installs split, multi-split, ducted reverse cycle, inverter and evaporative systems, and on the commercial side it handles VRV and VRF systems, upgrades and retrofits. Mitsubishi Heavy Industries is its featured brand.
Where it differs from installer-only businesses is its service work. The company offers routine maintenance, urgent repairs and breakdown callouts for all major brands, so it can look after a system someone else installed. That matters during a Perth heatwave, when a failed unit becomes urgent. The site does not list an ARCtick number or founding year, so check licensing when you book. It suits offices, shops and households in the northern suburbs who want one business for installation and ongoing service.
8. Slater Air — Family-Owned Perth Installer Of ActronAir And Advantage Air Systems
Slater Air describes itself as a family-owned, West Australian-owned business serving Perth and surrounding areas. Its principal, Darrell Slater, says he started in air conditioner manufacturing more than 30 years ago and set up his own business about 15 years ago. The company lists memberships of the Housing Industry Association and the Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH).
Slater Air handles residential and commercial installation, upgrades, maintenance and scheduled annual servicing. It works with ActronAir, Toshiba and Advantage Air, the last being a zoning and control system often used with ducted installs. A manufacturing background can help when designing duct layouts and zoning for larger homes. The site does not publish an ARCtick number or street address, so confirm these when you request a quote. It suits builders and homeowners planning a ducted system with zoning control.
How To Choose An Air Conditioning Company In Perth
Evaporative Or Reverse Cycle For A Perth Home?
Evaporative cooling works by pulling outside air through wet pads, so it performs best in dry heat and needs windows or doors open. It is usually cheaper to run, but it does not heat and is less effective on humid days. Ducted or split reverse cycle systems cool and heat in sealed rooms and handle humid days better, but cost more to run in peak summer. Many Perth households replace ageing evaporative systems with reverse cycle, so ask any Perth air conditioning installer to quote on both.
Which Licences Should An Installer Hold?
Anyone who handles refrigerant, which includes installing split and ducted reverse cycle systems, needs a licence from the Australian Refrigeration Council, known as ARCtick, and the business needs an ARCtick refrigerant trading authorisation. Electrical connection work in WA must be done by a licensed electrician working for a licensed electrical contractor, regulated by Building and Energy. Ask for both numbers, and check the ARCtick licence on the ARC’s online search.
How Is A System Sized For Perth Heat?
A proper quote should be based on a site visit that looks at room sizes, ceiling height, insulation, window orientation and how many rooms will run at once. West-facing rooms and upstairs areas in Perth heat up quickly in the afternoon, so they often need more capacity. Be wary of a quote given over the phone from floor area alone, because an undersized system will run flat out on a 40 degree day and still struggle.
What Should An Installation Quote Include?
Compare quotes on the same basis: the exact model numbers, the number of outlets or zones, the controller, any electrical upgrades, removal of the old system and the warranty on both the equipment and the installation. Ducted systems in particular vary on duct quality and roof access, which can change the price a lot. Ask whether the company services what it installs, since some businesses only supply and install.
When Is The Best Time To Book?
Demand peaks in late spring and the first heatwave of summer, when lead times stretch and urgent repairs take priority. Booking an installation in autumn or winter usually means more choice of dates and more time to compare quotes. An annual service before summer, including cleaning filters and checking evaporative pads, reduces the chance of a breakdown when you need cooling most.
Conclusion
Among the top air conditioning companies in Perth for 2026, Mouritz and Ford & Doonan offer the widest coverage and showroom access across Perth, while ACSIS, Wanneroo Gas & Air Centre and Jarrahdale Heating & Cooling are long-running family or independent businesses with strong local followings. Langler Air suits buyers who only need installation, All Air Services covers repairs and commercial systems, and Slater Air is a good option for zoned ducted work.
Whichever company you choose, ask for a site visit, a written quote with model numbers and the ARCtick and electrical licence details. For other household trades, see our guide to plumbers in Perth, or browse the Perth hub.
