Split system installation in Cannington
Cannington sits in Perth's established south-east, an inland activity-centre suburb where the housing runs from solid mid-century brick-and-tile to newer infill units and townhouses. That mix is exactly what shapes a good split install here.

Split system air conditioning for Cannington homes
A lot of Cannington's housing stock is the older brick-and-tile that defined Perth's south-east through the post-war decades. These homes are well built but often still run an original switchboard that was never sized for modern reverse-cycle air conditioning. The most common job we handle is adding a dedicated circuit so a new split can run safely on its own breaker. Because Otter Air is dual-licensed for both air conditioning and electrical, we do that switchboard and wiring work in-house on the same visit, rather than leaving you to chase a separate sparky to finish the job.
The typical Cannington brief is straightforward: cool the master bedroom and the main living area where the family actually spends time. On the older single-storey homes that usually means a tidy back-to-back install through a brick cavity, keeping the line set short and the outdoor unit neatly against a side or rear wall. Where there's a newer two-storey townhouse or infill build closer to the activity centre, we'll plan upstairs routing and longer runs, or talk through a multi-head system if you want several rooms zoned off one outdoor unit. Being inland, salt-air corrosion isn't a concern here, so unit placement is driven by airflow and access rather than coastal protection.
We also see plenty of replacement work in Cannington, swapping out tired old units that have stopped keeping up through Perth's long, dry summers. If you're after air conditioning Cannington homeowners can rely on, we'll size the unit to the actual room rather than overselling, check the existing wiring, and leave the site clean. Every split system installation Cannington job is quoted up front with no surprises.

See all reviews“Excellent Air Conditioning Installation Service! ⭐️⭐️⭐️⭐️⭐️ When looking to install 2 new aircons at my house, I was recommended to use Otter Air & Electrical and I couldn't be happier with the service provided by Matt and his assistant. From the initial enquiry through to the completion of the installation, the entire experience was seamless, professional and efficient. Matt responded promptly to emails, arrived exactly on time as scheduled, highly professional and the whole experience was stress-free. On the quote, he provided a few options with breakdown details of what is included in the price and makes it easier to make the decision. On the day of installation, the process was completed on schedule and I'm very happy with the quality of the work. They took great care to keep the work area clean and tidy throughout the job, and once finished, they thoroughly cleaned up, leaving everything spotless. Thank you very much, Matt and team and I would highly recommend this company to anyone looking for a reliable, professional and efficient aircon company.”
