- 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 Bunbury, Australind, Eaton and the South West coast and estuary suburbs.
- 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 dozens 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 bigger 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, cleaners and other trades left out. These searches also pull up air con stores and showrooms, supply warehouses, auto mechanics and split-system cleaning specialists. 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.
Jazac Air – Heating and Cooling Specialists
A 4.9 held across 287 reviews is by a clear margin the deepest body of proof on this page, and that depth is exactly why the volume weighting puts them first. Heating and cooling is the whole job here, from a single bedroom split in Withers or College Grove to a whole-home ducted reverse-cycle fit-out out at Treendale, Millbridge or Dalyellup, plus servicing and no-cool repairs across the South West. When a rating that strong holds up over that many jobs, it usually points to consistent sizing and tidy, repeatable work, so this is a safe first call for the Bunbury end of the cluster.
View listing & contact ▸DG Air South West
A spotless 5.0 across 64 reviews, which is a strong base to hold a perfect score over, and enough proof to sit just behind Jazac on the weighting. A clean sheet that many customers deep usually means careful sizing, tidy installs and problems sorted without fuss. For supply-and-install and servicing around Bunbury, Australind, Eaton and the estuary suburbs, this is about as safe a first call as you’ll find down here.
View listing & contact ▸Bunbury Refrigeration and Air Conditioning
A 5.0 across 50 reviews and a genuine air conditioning and refrigeration outfit carrying the town’s name. A perfect rating over that many jobs points to steady, careful work, and a firm that does refrigeration as well as air con generally knows its way around a system inside and out. A strong choice right across the cluster, from splits in the older brick homes to ducted work in the newer estates.

A note on the ranking: Jazac Air leads clearly on the deepest verified base here, a 4.9 across 287 reviews, well ahead of the pack on proof. Behind them sits a tight run of perfect 5.0 scores ordered by how many jobs back them up: DG Air South West (64), Bunbury Refrigeration and Air Conditioning (50), CoolPro (46) and Pergo Air (37). QM Airconditioning’s 5.0 across 17 and Ford & Doonan Bunbury’s 4.7 across 55 land in a photo finish at sixth and seventh, the perfect-but-thinner score edging the bigger-but-lower one by a whisker on the weighting. AirCo South West and Bissaker Air & Electrical round out the ten on clean 5.0s that just need a few more jobs behind them to climb. We list only real, review-bearing installers and never pad the list. NIXON Bunbury, the biggest name in the search, is an electrician-first firm that also fits air con, and it already sits at the top of our best electricians page for Bunbury, so we’ve named it here rather than doubling it up on the aircon ranking. A couple of listings at or below our 4.3 rating floor, and the local auto mechanics and auto electricians the search throws up, were left off.
What air conditioning actually costs around Bunbury and Australind (2026)
Nobody likes ringing an installer blind on price. These are honest ballpark ranges for the common jobs around Bunbury, Australind, Eaton and the South West suburbs, 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 |
Bunbury sits right on the coast, and that shows up in the quotes. From the beaches and Koombana Bay in town out to Usher and Pelican Point, the salt air chews through outdoor condenser units faster than most of inland WA, 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 homes ringing the Leschenault Estuary at Australind, Eaton and Pelican Point cop that salt load plus a bit more humidity off the water, which is hard on coils. The newer estates at Treendale, Millbridge, Dalyellup and Gelorup are mostly ducted-reverse-cycle territory, while the established brick-and-tile streets of Bunbury, Withers, Carey Park and College Grove are steadily swapping tired evaporative units for reverse-cycle splits. The South West runs colder and wetter in winter than Perth, so reverse-cycle earns its keep for heating as much as cooling down here. Jobs out at the edges, Brunswick Junction, Stratham, Gwindinup and Capel, can carry a small travel loading. 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.
- No plan for the salt air. Right on the coast at Bunbury and around the Leschenault Estuary, a standard condenser can rust out years early. A switched-on local installer will talk to you about a coated or marine-grade outdoor unit and where to site it out of the worst of the salt spray. If salt never comes up, they don’t know this patch.
- 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.
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.
- Coastal-rated outdoor unit. If you’re near the beach or the estuary, ask about a coated or marine-grade condenser and sensible siting away from the salt spray.
- 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 Bunbury, Australind, Eaton and the South West coast and estuary suburbs. We weight the rating by review volume so a proven score from dozens of customers isn’t leapfrogged by a perfect score from a handful. That same weighting is why Jazac Air, on a 4.9 across 287 reviews, leads the page by a clear margin, why a run of perfect 5.0s sits behind it ordered by how many jobs back them up, and why QM’s 5.0 across 17 and Ford & Doonan Bunbury’s 4.7 across 55 land in a near tie at sixth and seventh. All ten are working air con installers, not retailers, wholesalers or cleaners.
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 in the South West?
Both suit the WA 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 off the estuary, 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. Because the South West winters are colder and wetter than Perth, plenty of Bunbury and Australind homes are choosing reverse-cycle so one system handles both seasons, and near the coast and the Leschenault Estuary a reverse-cycle split with a coated condenser tends to be the safer long-term pick.
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. West-facing homes catching the afternoon sun off the water carry extra load, which is a lot of houses down here. 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.
Does the coastal salt really matter for my air con?
Yes, more than most people expect. Salt-laden air rusts standard outdoor condenser coils and casings, and right on the beach in Bunbury or around the Leschenault Estuary at Australind, Eaton and Pelican Point, a unit can age years faster than the same one a few kilometres inland. A coated or marine-grade condenser, sensible siting out of the direct salt spray, and a yearly wash-down and service all add up to a system that lasts. It’s worth raising with any installer you call.
