Split system air conditioning for Southern River homes
Most of Southern River went up from the late 1990s onward, so the housing here skews modern: brick-and-tile family homes on generous estate blocks, plenty of double-storey designs, and the large open-plan kitchen-living-meals zones that newer builds favour. Those big rooms are the number one thing we plan around. A single undersized head will run flat out and never quite get there, so for an open-plan heart-of-the-home we'll size the unit to the actual volume of the space, not just the floor area, and position the indoor head to throw air across the whole room rather than into a wall.
Being inland in the 6110 corridor, Southern River cops the dry, baking summers Perth's south-east is known for, well away from any coastal salt. That makes a reverse-cycle split a strong all-rounder here: hard cooling through February, gentle heating on those cold winter mornings. A common job for us is cooling a master bedroom plus the main living area, or running a multi-head system in a double-storey home so upstairs bedrooms stay liveable without a row of outdoor units along the side of the house. We plan upstairs refrigerant runs carefully and finish them in neat conduit.
Because Otter Air is dual-licensed in air conditioning and electrical, we handle the whole split system installation Southern River homeowners need under one roof. If your switchboard is full or needs a new dedicated circuit for the unit, we do that in-house on the same visit - no waiting on a separate sparkie. Replacing a tired old unit on an established block? We'll reuse what we sensibly can and quote it straight, with upfront fixed pricing.

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.”
