Ultima Air
Wayne has saved multiple customers from five-figure replacements by repairing what other companies said was beyond fixing.
That's a meaningful differentiator when a ducted replacement can run to $15,000. Josh and the installation crew are specifically praised for fast, tidy on-site work and thorough handovers where they walk customers through new control systems step by step. One review raises a concern about a builder-managed install where handover was never completed and airflow issues went unresolved — this appears to be an isolated case in the sample, and it's worth confirming directly with Wayne that all post-install walkthroughs are scheduled before work begins, particularly on new-build projects coordinated through a third-party builder.

About Ultima Air
Wayne (owner) and Josh (lead installer) are the two names that appear repeatedly across dozens of jobs — Wayne handles consultations, system design, and diagnostics, while Josh leads the installation crew on-site. What sets them apart in Adelaide's crowded AC market is a willingness to repair systems that competitors have written off: multiple customers describe being quoted $10,000–$15,000 for replacements by other companies, only for Wayne to fix the fault with a capacitor or sourced part for a few hundred dollars. They hold Diamond Mitsubishi dealer status and work across Actron, Panasonic VRF, and AirTouch 5 systems, with particular depth in complex ducted retrofits — attic conversions with minimal ceiling cavity, multi-split systems built into bulkheads with no visible wall units, and full duct redesigns to fix poorly performing inherited systems. New builds are a core niche: a building company (Ad Homes) that has partnered with them for over a decade notes that an independent building inspector called one of their installs 'one of the best residential air conditioning installations I have seen.' Post-installation follow-up is a recurring pattern — Wayne personally phones customers after jobs and has returned years later, free of charge, to service filters and fine-tune airflow on systems he originally fitted.
Best for: complex ducted retrofits in homes with non-standard layouts, second opinions before committing to a costly system replacement, new builds requiring end-to-end AC design and installation, and homeowners who want long-term aftercare from the company that did their original install.

Does Ultima Air do repairs, or only new installations?+
Repairs are a genuine specialty — multiple customers in reviews describe Wayne diagnosing faults that two or three other companies had declared unfixable or not worth repairing. Common fixes include capacitor replacements, refrigerant leaks, and duct airflow corrections. Wayne has also sourced obsolete parts for systems over 20 years old to avoid unnecessary replacements. If you've already been told you need a full new system, it's worth getting a second opinion from Ultima Air before committing.
What brands does Ultima Air work with?+
Reviews mention installations across Actron, Mitsubishi Electric, and Panasonic VRF systems, as well as AirTouch 5 smart control panels. Ultima Air holds Diamond dealer status with Mitsubishi, which is the top tier of their residential dealer program. They've also worked with less common configurations like Panasonic multi-split VRF systems built into ceiling bulkheads — a setup that several other Adelaide companies told one customer they couldn't do.
How does Ultima Air handle complex or non-standard jobs?+
Complex retrofits and non-standard designs appear regularly in their reviews — including attic conversions with minimal ceiling cavity, homes where old evaporative and gas systems needed removing before a new ducted system could be designed, and multi-split systems hidden in bulkheads with custom-fabricated grilles. Wayne handles the upfront design work personally and is specifically praised for thinking through constraints that other companies didn't engage with. Customers with challenging layouts consistently describe this as the reason they chose Ultima Air over others who quoted.
What is the installation process like — how long does it take and is the house left tidy?+
Most residential ducted installs appear to be completed in a single day based on customer reviews, with Josh leading the on-site crew. Cleanup is consistently mentioned — old systems, packaging, and off-cuts are removed at the end of the job. Josh is specifically praised for walking customers through the new system controls during handover, including WiFi app setup where applicable. Wayne typically follows up by phone after installation to check the system is performing as expected.
Does Ultima Air manage related trades like plasterers and electricians?+
Yes — several reviews mention Ultima Air coordinating electricians, plasterers, and painters as part of the job, particularly where old systems left holes in ceilings or walls. Customers describe this project management as one of the things that distinguished Ultima Air from competitors who left the homeowner to coordinate other trades themselves. If your job involves removing old systems or making good after installation, it's worth asking Wayne at the quote stage what's included in their scope.
