Best air conditioning installers in Stirling and Scarborough (2026)
Table of Contents
These are the ten best-rated air conditioning installers working Stirling, Scarborough and the surrounding coast-to-freeway belt, from the beach suburbs at Scarborough, Trigg, North Beach and Watermans Bay, through Karrinyup, Carine, Gwelup and Doubleview, and inland across the Osborne Park and Balcatta trade hub to Innaloo, Tuart Hill, Joondanna and Yokine. They’re ranked on real Google reviews, not on who paid us. Below the list you’ll find what a split-system, a ducted reverse-cycle job or a service actually costs around here in 2026, the red flags that tell you to hang up the phone, and a quick checklist to run before you let anyone drill through your wall.

- Google reviews do the ranking. We start with every installer’s live Google star rating and the number of reviews behind it, pulled fresh from Google Maps across Stirling, Scarborough, Osborne Park and Balcatta.
- Rating, weighted by volume. A 5.0 from a handful of jobs isn’t proof yet, so we weight the score by review count. A proven rating from hundreds of customers isn’t beaten by a perfect score from a few. It also means a very strong 4.9 or 4.8 backed by a big review base can sit ahead of some perfect scores with thinner bases.
- Licence matters. Split-system work handles refrigerant, so a legitimate installer holds an ARCtick (Australian Refrigeration Council) licence and uses a licensed electrician for the electrical connection. We tell you how to check both yourself in the checklist.
- Retail stores, wholesalers and other trades left out. The Osborne Park strip is thick with air con stores, wholesalers and electricians whose Google listings show up under these searches. They’re real businesses, but they’re not the house-call installer you book, so we’ve kept them off this list along with any listing carrying only a review or two.
- Paid spots are labelled, and never jump the queue. When a business pays for a “Featured” spot it’s marked as such. The review-based order below does not change to favour a payer. Right now, no spots are sold.
TOTAL AIR – All Things Air Conditioning Perth
A 4.8 held across more than 650 reviews is by a clear distance the biggest body of proof on this page, and that depth is exactly why the volume weighting puts them first. Based on the Osborne Park trade strip right in the middle of this cluster, they cover the lot, from a single bedroom split to a whole-home ducted reverse-cycle fit-out, plus servicing and no-cool repairs. When a rating that strong holds up over that many jobs, it usually means consistent sizing and tidy work, so this is a safe first call for the Stirling and Scarborough area.

A clean 5.0 across 75 reviews is a genuine standout, and being based in Balcatta puts them right in the heart of this cluster. A perfect sheet over that many installs points to careful sizing and neat finishing, which is what you want before someone runs pipe through your roof space. The volume weighting nudges them ahead of some bigger-but-lower-rated names because that perfect rating is backed by a solid base. A strong choice for supply-and-install work around Stirling, Karrinyup and the coast.
View listing & contact ▸Ford & Doonan Air Conditioning Osborne Park
A 4.8 across 164 reviews and the local branch of a name plenty of Perth homeowners already know. This is the house-call installer side of the business rather than the retail head office, so you get a well-resourced outfit that handles everything from a bedroom split to a full ducted or evaporative system. Any of the top few here is a solid first call; the order between them comes down to review weight and rating, not a gap in quality.
View listing & contact ▸A note on the ranking: TOTAL AIR leads on the biggest verified base by far, a 4.8 across more than 650 reviews, which the volume weighting keeps ahead of the perfect scores with thinner bases. Langler Air’s clean 5.0 across 75 edges past Ford & Doonan Osborne Park’s 4.8 across 164 on the weighting, and Crispair (4.6 across 374) and Airforce (4.6 across 247) earn their spots because a strong rating over a big base beats a perfect score from a handful. We list only real, review-bearing installers and never pad the list. Ford & Doonan’s head office (listed as an air conditioning store rather than a house-call installer), Response Electricians (an electrician), the Osborne Park wholesalers and supply houses, and Stinson Air & Solar (4.5 across 177, which lands right on our baseline so its volume gives no lift) were left off, along with thin listings carrying only a review or two. We’ve also held back Air Conditioning Industries WA and AAA Airconditioning & Electrical, two Perth-wide operators already featured in our Joondalup and northern-suburbs list, to keep this page anchored to installers based in and around Stirling and Osborne Park.
What air conditioning actually costs around Stirling and Scarborough (2026)
Nobody likes ringing an installer blind on price. These are honest ballpark ranges for the common jobs around Stirling, Scarborough and the Osborne Park belt, GST and standard install included. They’re a guide to keep you from being overcharged, not a quote. Air con pricing swings a fair bit on brand, capacity and how hard your house is to run pipe through, so always get the job priced in writing before work starts.
| Job | Typical range | What pushes it up |
|---|---|---|
| Service, clean & check (split) | $120-$220 | Multiple units, mould clean, coastal salt build-up |
| Re-gas / refrigerant top-up | $180-$450 | Finding and fixing the leak first, larger systems |
| Fault find / no-cool call-out | $90-$180 | After-hours, older systems, parts on top |
| Supply & install split (2.5-3.5kW, bedroom) | $1,200-$2,200 | Premium brand, double-brick wall, upstairs, long pipe run |
| Supply & install split (5-7kW, living area) | $2,200-$3,800 | Second-storey, roof access, switchboard upgrade |
| Multi-head split (2-3 indoor heads) | $4,500-$8,500 | Number of heads, pipe runs, brand |
| Ducted reverse-cycle, whole home | $9,000-$18,000+ | Home size, zones, single vs three-phase, roof space |
| Add a zone / extra ducted outlet | $300-$700 | Ceiling access, damper and controller |
| Evaporative cooler supply & install | $3,500-$6,500 | Roof type, ducting runs, controller |
| Evaporative service / pad replacement | $150-$400 | Pad type, pump or motor parts |
| Relocate an existing split head | $350-$700 | New pipe run, re-gas, patching the old spot |
This cluster is a real mix of housing, and that shows up in the quotes. Right on the coast at Scarborough, Trigg, North Beach and Watermans Bay, the salt air chews through outdoor condenser units faster than most of Perth, so a coated or marine-grade condenser and a yearly wash-down are worth the small premium, and units near the water simply wear out sooner. The established suburbs around Karrinyup, Carine, Gwelup, Doubleview and Wembley Downs are full of solid double-brick homes, many still on evaporative or older single splits and moving across to reverse-cycle, and double-brick walls mean more work to run and cover the pipe. Inland at Balcatta, Stirling, Tuart Hill, Joondanna and Yokine you get a spread of post-war homes and newer infill builds, with plenty of two-storey developments where roof access and longer pipe runs lift the price. A licensed installer should give you a fixed price or a not-to-exceed figure, in writing, before starting. If they can’t, that’s a red flag (see below).
Don’t get ripped off: red flags
- No ARC licence for the refrigerant. Anyone installing or decommissioning a split-system handles refrigerant, and that legally requires an ARCtick (Australian Refrigeration Council) licence. The electrical connection also needs a licensed electrician. If they can’t give you an ARC number, walk away, no exceptions.
- Quoting a system without sizing it. A good installer measures the room or home, ceiling height, window aspect and insulation, and sizes the kilowatts to suit. “She’ll be right, we’ll put a 7kW in” without measuring gets you an over- or under-sized unit that either short-cycles or runs your power bill up all summer.
- A cheap “supply & install” that skips the electrical or the brackets. Suspiciously low quotes often leave out the isolator switch, proper wall brackets, pipe covers or the electrical connection, then expect your own sparky to finish it. Get the inclusions in writing.
- Cash only, no receipt, no warranty paperwork. Manufacturer warranties (often five years) only stand if the unit is installed by a licensed installer with the paperwork to prove it. No paper, no warranty, and no comeback if it fails.
- Pushing ducted or a top-tier brand when a couple of splits would do. An upsell to a $15,000 ducted system when two well-placed splits would cool the house is common. On any big-ticket job, get a second quote before you sign.
Before you hire: quick checklist
- ARC licence. Confirm the installer holds a current ARCtick licence for refrigerant work, and that a licensed electrician does the electrical connection. Check the ARCtick number at arctick.org.
- Insurance. Ask for current public liability cover, it protects your home if something goes wrong.
- Written quote. Itemised and in writing, including brand, model, kW capacity and whether the electrical and isolator are included, before work starts.
- Capacity sizing. They measured the space and sized the unit to it, rather than eyeballing a number over the phone.
- Warranty. Confirm the manufacturer warranty is registered in your name and you get the installer’s workmanship warranty in writing.
- Recent reviews. Look for recent, specific reviews, not just a big number. A steady stream of detailed 5-star installs beats one old burst of them.
Frequently asked
How did you rank these installers?
By their live Google star rating and the number of reviews behind it, pulled from Google Maps across Stirling, Scarborough, Osborne Park and Balcatta. We weight the rating by review volume so a proven score from hundreds of customers isn’t leapfrogged by a perfect score from a handful. That same weighting is why TOTAL AIR, on a 4.8 across more than 650 reviews, leads the page, and why strong 4.6 operators with big bases sit ahead of some thinner perfect scores. All ten are working air con installers, not retailers or wholesalers.
Are these paid placements?
No. This list is ordered on Google review data. Businesses can pay for a “Featured” spot at the top, which is clearly labelled, but paying never changes the review-based order below. As of this update, no spots are sold.
Reverse-cycle or evaporative around Stirling and the coast?
Both suit the dry Perth heat, but they do different jobs. Evaporative cooling is cheaper to run and moves a lot of fresh air, but it struggles on the humid days, can’t heat in winter, and doesn’t love the salt air right on the coast. Reverse-cycle both cools and heats, works in any weather, and suits well-sealed homes. On the coast at Scarborough, Trigg and North Beach, reverse-cycle with a coated condenser tends to be the safer long-term pick, while plenty of the double-brick homes around Karrinyup and Gwelup are swapping tired evaporative units for reverse-cycle.
What size air conditioner do I need?
As a rough guide, a bedroom might need 2.5 to 3.5kW, a medium living area 5 to 6kW, and an open-plan living and kitchen 7 to 9kW or more, but ceiling height, window size and aspect, and insulation all move that number. Perth’s western sun through big windows adds load, which matters in a lot of these coast-facing homes. Don’t guess it: a good installer measures the space and sizes the unit, because an over-sized system short-cycles and an under-sized one never quite gets there.
Do I need a licensed installer?
Yes. Installing a split-system handles refrigerant, which legally requires an ARCtick licence, and the electrical connection must be done by a licensed electrician. DIY installs void the manufacturer warranty, can void your home insurance, and often leak refrigerant or trip out. Booking a licensed installer is the only way the warranty and the paperwork actually stand.
How often is this page updated?
Monthly. Ratings and review counts move, new installers earn their spot, and we re-pull the data so the list stays honest and current.
