Split system installation in Wilson

Wilson sits on the bend of the Canning River in Perth's established south-east, and its quiet, leafy streets are full of older homes that were never built with modern cooling in mind. That is exactly where a well-planned split system earns its keep.

Split system air conditioning for Wilson homes

Much of Wilson is original 1960s and 70s brick-and-tile on generous blocks, the kind of solid double-brick home that holds heat through a long Perth summer and was wired well before reverse-cycle was common. When we quote a split system installation in Wilson, the first thing we look at is the switchboard. Plenty of homes here still run older boards with limited spare capacity, and a new high-wall or ducted-style split needs its own dedicated circuit. Because Otter Air is dual-licensed for both air conditioning and electrical, we add that circuit, upgrade tired switchboards and bring the wiring up to standard in-house, so you are not chasing a separate sparky to finish the job.

The most common request we get for air conditioning in Wilson is cooling the main living zone and the master bedroom, often replacing a noisy, end-of-life unit that has finally given up. On the larger, deeper blocks around the riverside pockets, the outdoor condenser sometimes needs a longer line run to reach a discreet, shaded spot, which we plan up front so performance and warranty are not compromised. Where homes have been extended or had a second storey added, a multi-head system lets us cool several rooms from one outdoor unit and keep the exterior tidy.

Being inland and close to the Canning River bushland, Wilson runs hot and still on summer afternoons, so we size each unit to the room and the home's brick mass rather than guessing. Every install is left neat, properly sealed and tested before we leave.

“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.”
