Split system air conditioning for Mount Pleasant homes

Mount Pleasant sits on the south-east side of the river near the Canning and Swan confluence, an older, leafy suburb where the housing stock tells two stories. Plenty of the original post-war brick-and-tile homes are still here, often on generous blocks, and many still run the switchboard they were built with. When we fit a split system to one of these, the air conditioning side is only half the job - we frequently need to add a dedicated circuit and, in older homes, recommend a switchboard upgrade with RCD protection. Because Otter Air is dual-licensed for both air conditioning and electrical, that all happens in-house, so you are not waiting on a separate sparky to finish the wiring.

The other half of Mount Pleasant is the knock-down-rebuild wave that has reshaped the suburb, especially closer to the river. These double-storey homes suit multi-head systems, where one outdoor unit feeds several rooms, and they often call for careful planning to route lines up to upstairs bedrooms cleanly. We also see a steady stream of replacements - tired ducted or wall units in homes that have been here for decades. Whether it is cooling a master and open-plan living, or a full multi-head layout for a two-storey rebuild, we size the unit to the room and the aspect, not just the floor area.

For a split system installation Mount Pleasant homeowners can rely on, we focus on tidy line runs, sensible outdoor unit placement that respects neighbours and river-view sightlines, and compliant electrical work signed off properly. As a local south-east Perth contractor based nearby in Huntingdale, we know the area well.

“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.”
