- 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 Rockingham, Baldivis, Mandurah and the 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.
Ford & Doonan Air Conditioning Mandurah
A 4.9 held across 175 reviews is the strongest body of proof on this page, and that depth is exactly why the volume weighting puts them first. This is the Mandurah branch installer that does the house calls, not the retail store, and they work right across the Peel and southern coast, from a single bedroom split at Halls Head or Erskine to a whole-home ducted reverse-cycle fit-out over at Dawesville or Lakelands, 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 Mandurah end of the cluster.
View listing & contact ▸Total Kooling Solutions
The deepest review base on the whole page, a 4.8 across 310 reviews, and a well-known Rockingham name based on Dixon Rd. A rating that holds up over 300-plus jobs is serious proof of consistent work, and it sits just behind the leader only because that 4.8 is a hair under Ford & Doonan’s 4.9. For supply-and-install and servicing around Rockingham, Baldivis, Warnbro and Secret Harbour, this is about as safe a first call as you’ll find down here.
View listing & contact ▸MSF Electrical and Air Conditioning
A 4.9 across 113 reviews and a genuine air conditioning contractor that also carries its own electrical side, which is handy because the electrical connection is part of every split install. A near-perfect rating over that many jobs points to careful, consistent work, and having the sparky in-house can mean one team, one booking and no waiting on a second trade to finish the job. A strong choice across the cluster.

4.7 (122)
A note on the ranking: Ford & Doonan Mandurah leads on the strongest verified base here, a 4.9 across 175 reviews, which the volume weighting keeps just ahead of Total Kooling Solutions, whose bigger 310-review base sits at a 4.8. MSF’s 4.9 across 113 takes third. Further down, the weighting rewards a deep base over a thin perfect score, which is why iBreeze (4.8 across 170) and Air Craft HVAC (4.9 across 85) sit ahead of some smaller 5.0s, and Complete Refrigeration & Air rounds out the ten on a clean 5.0 that just needs a few more jobs behind it to climb. We list only real, review-bearing installers and never pad the list. Ford & Doonan’s head office and the Hearth House and Energy House showrooms (air conditioning stores rather than house-call installers), the Rockingham auto mechanics and auto electricians, The Good Guys and Betta (retail), a couple of listings below our 4.3 rating floor and any with only a review or two were all left off. We’ve also kept the local electricians who also fit air con, such as JFK Electrical Solar & Air and Dodds Electrical & Air, on our best electricians page for this area rather than doubling them up here.
What air conditioning actually costs around Rockingham and Mandurah (2026)
Nobody likes ringing an installer blind on price. These are honest ballpark ranges for the common jobs around Rockingham, Mandurah and the southern coastal 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 |
This cluster runs right along the coast, and that shows up in the quotes. From Rockingham, Shoalwater and Safety Bay down to Mandurah, Halls Head and Falcon, 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 canal and estuary homes around Mandurah, Port Kennedy, Silver Sands and Erskine cop that salt load plus a bit more humidity off the water, which is hard on coils. The newer two-storey estates at Baldivis, Secret Harbour, Golden Bay, Lakelands and Meadow Springs are mostly ducted-reverse-cycle territory, while the established brick-and-tile streets of Rockingham, Warnbro and Greenfields are steadily swapping tired evaporative units for reverse-cycle splits. Jobs out at the far ends, Singleton, Dawesville and the estuary’s south side, 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 and around the Mandurah canals, 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 canals, 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 Rockingham, Baldivis, Mandurah and the 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 Ford & Doonan Mandurah, on a 4.9 across 175 reviews, leads the page, why Total Kooling Solutions’ bigger 310-review base at 4.8 sits right behind it, and why a strong 4.8 over a big base (iBreeze) earns a spot ahead of some thinner perfect scores. 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 on 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 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. Along the Rockingham and Mandurah coast and around the canals, reverse-cycle with a coated condenser tends to be the safer long-term pick, while plenty of the older brick homes inland at Warnbro and Greenfields 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. 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 at Rockingham, Shoalwater and Safety Bay, or around the Mandurah and Port Kennedy canals, 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.
