Mulherin Air & Electrical
John Eddy personally oversaw one customer's Daikin install — and another kept coming back five times over eight years.
That said, the signal from those 3 reviews is clean: John Eddy is named directly by a customer as being present and engaged during the installation itself, pricing is described as competitive, and one customer has come back five or more times over several years. For a business that's been trading roughly a year, that repeat-use behaviour is the most practically useful data point — it suggests the experience after the sale is good enough to bring people back. If you're considering them for a new split system or ducted install, ask specifically whether John will be on-site for your job.

About Mulherin Air & Electrical
John Eddy leads the installations side of the business directly — one customer notes he answered all their questions and oversaw the Daikin 9kW reverse cycle fitout himself, which is the kind of hands-on principal involvement that's rare once a company starts scaling. The business spans both air conditioning and electrical work, which means they can handle the full scope of a split system or ducted installation without subcontracting the wiring side. Daikin systems appear to be a product line they're comfortable recommending and installing, including models with integrated air filtration — worth knowing if indoor air quality is a priority for your household. At least one customer has returned five or more times across several years for servicing and repairs, suggesting the relationship-based side of the business is intact even as the company is relatively new to trading under this name. Pricing is called out in the reviews as competitive without any prompting, which is a signal worth noting when getting quotes in Mackay's market. They suit homeowners looking for a single contractor who can manage both the refrigerant and electrical licensing requirements of a new install, or anyone wanting continuity of service across annual maintenance and repair callouts.
Best for: new Daikin split system or reverse cycle installs where you want the principal on-site, homeowners wanting a single contractor for both electrical and refrigeration licensing, and repeat maintenance or repair servicing on existing systems.

Does Mulherin Air & Electrical handle both the air conditioning and electrical work for a new install?+
Yes — the business holds credentials across both air conditioning and electrical trades, which means they can manage the refrigerant and wiring components of a new installation without bringing in a separate electrician. This is worth confirming when you call, but their Google categories list both electrician and general contractor, and customer reviews describe full system installations rather than partial work. For homeowners in Mackay getting a new split system or ducted unit fitted, this single-contractor setup can simplify scheduling and accountability.
What brands does Mulherin Air & Electrical install?+
At least one customer review specifically mentions a Daikin 9kW reverse cycle system being installed, including a model with an integrated air filtration system. This suggests familiarity with the Daikin product range, though the reviews don't confirm whether they're an authorised Daikin dealer. If brand certification matters for your warranty, ask them directly when requesting a quote.
Does John Eddy show up on-site, or does he send a crew?+
One customer specifically notes that John Eddy answered their questions and personally oversaw the installation — that level of principal involvement is mentioned as a positive. Whether that's standard practice for every job or reserved for larger installs isn't clear from the available reviews, so it's worth asking upfront if you want the owner on-site for your job. With only 7 total reviews to draw from, we can't say this is a guaranteed pattern, but it's been called out as a distinguishing quality.
How does Mulherin Air & Electrical handle ongoing maintenance and repairs?+
One repeat customer mentions using the business for cleanings and repair callouts roughly five times over eight years, describing them as responsive and professional across those visits. This suggests the business maintains service continuity beyond the initial install rather than focusing exclusively on new sales. If you're looking for a single provider to handle annual servicing and ad-hoc repairs on an existing system, that pattern is encouraging — though with a small review sample, confirm directly that they service all major brands, not just systems they've installed.
Is Mulherin Air & Electrical pricing competitive in the Mackay market?+
Pricing is described as competitive in one of the reviews, mentioned unprompted alongside workmanship quality — which is a stronger signal than when it appears in response to a direct question about cost. That said, only 7 reviews exist in total, so this isn't a large-sample consensus. Getting two or three quotes for any job over a few hundred dollars is still good practice, but nothing in the available reviews suggests pricing has been a point of contention.
