Alliance Air Conditioning
Glenn fixed a Daikin fault in one visit that three years of brand servicing couldn't resolve.
The sample is too small to map the full range of work Alliance handles, but across these five accounts, pricing is described as fair or slightly below comparable local quotes, and the crew consistently handles both the installation and the electrical coordination internally. If you're dealing with a fault that's already stumped another technician, or you want a written quote from a tradesperson who'll actually respond, the review pattern here suggests Alliance is worth calling — just confirm their availability in your part of Mandurah before booking.

About Alliance Air Conditioning
Glenn is the name that comes up repeatedly in these reviews, and what he's specifically praised for is troubleshooting problems that other technicians — including brand service teams — couldn't resolve. One reviewer spent three years chasing a Daikin central unit fault through a builder's service agreement before Glenn diagnosed it in a single visit, tracing the issue to a controller and zone panel installed too close together, causing a 4°C temperature sensor error. Brad and Shona are also mentioned by name for handling storm-damage repair jobs with urgency and clear communication throughout. The team operates across new split system installations, existing system repairs, and diagnostics on complex multi-zone setups in double-storey homes — not just straightforward swap-and-go work. Quotes are provided in writing promptly, which several customers contrasted against local competitors who didn't respond at all, and installations are coordinated with electricians so homeowners deal with one point of contact rather than juggling trades. Workmanship reviews mention the crew arriving on time, explaining what they're doing, and leaving the job site clean — details that indicate a structured process rather than ad hoc scheduling.
Best for: complex ducted system faults that other technicians have failed to diagnose, new reverse cycle split system installations in residential homes, and homeowners who want a single point of contact for both the air conditioning and electrical work.

What does Alliance Air Conditioning specialise in?+
Based on the reviews available, Alliance handles both new split system installations and repairs or diagnostics on existing systems — including complex multi-zone ducted setups in double-storey homes. Glenn is specifically mentioned for fault-finding on systems that had already stumped brand service teams, suggesting a diagnostic depth beyond standard installation work. Brad is also named in at least one review involving storm-damage repairs. The business appears to suit homeowners with tricky existing systems as much as those after a straightforward new install.
Does Alliance Air Conditioning organise the electrical work, or do I need to book a sparkie separately?+
Multiple reviews mention that Alliance coordinates the electrician as part of the job, so you don't need to arrange that separately. One reviewer specifically noted this as a convenience when the electrical component was required to complete a repair. For installations, reviewers describe the fitters and electricians arriving in sequence on the same day. Confirm this is still the case when you get your quote, as trade coordination can vary by job type.
How quickly does Alliance Air Conditioning respond to quote requests and urgent jobs?+
Reviewers consistently mention prompt responses — one customer received a written quote within a day while other local companies didn't respond at all. A separate review describes Alliance attending at short notice to restore a system quickly. The business is a sole trader operation, so availability during peak summer periods may be tighter — it's worth calling ahead rather than assuming immediate availability. That said, the communication pattern in reviews suggests they keep customers informed about timing rather than going quiet.
What do customers say about Alliance Air Conditioning's pricing?+
Pricing feedback in the available reviews is consistently positive — one customer described Alliance as 'on par, perhaps a little cheaper' than other companies after getting multiple quotes, and another noted their work was 'fairly priced.' No reviewers flagged pricing as a concern in this sample. Because we only have 5 reviews to draw from, it's worth getting a written quote to compare — the good news is reviewers specifically mention that Alliance provides proper written quotes promptly, which makes comparison straightforward.
Is Alliance Air Conditioning suitable for diagnosing ongoing faults that other technicians haven't fixed?+
This appears to be a genuine strength based on the reviews available. One customer had spent three years trying to resolve a temperature control fault in a Daikin 16kW central system through the builder's service agreement with no success — Glenn diagnosed and fixed it on a single visit by identifying an installation error with the controller placement. Glenn is also described as taking time to explain what he found and why, rather than simply suggesting a system upgrade. If you've already had another company look at your system without resolution, this pattern suggests Alliance is worth a call.
