Split system air conditioning for Haynes homes

Sitting in the south-eastern corridor near Armadale, Haynes is a young estate suburb - most homes here have gone up over the last couple of decades on relatively compact lots. That newer building stock is generally a help for a split install: switchboards tend to be modern, often with RCD protection already in place and a little spare capacity, so adding a dedicated circuit for an outdoor condenser is usually straightforward. Because Otter Air is dual-licensed for both air conditioning and electrical, we handle the cabling, the circuit and the mount as one job rather than leaving you to chase a separate sparkie.

Two scenarios come up a lot in Haynes. The first is a single high-output split sized for an open-plan living, kitchen and dining zone - the layout most of these newer homes share. The second is the double-storey home, where owners want a head in the downstairs living area plus one or two upstairs bedrooms; a multi-head setup lets us run that from a single outdoor unit, with line sets routed neatly through the roof space and wall cavities. On the tighter estate blocks, careful condenser placement matters so the outdoor unit clears the boundary, stays serviceable and doesn't sit under a bedroom window next door.

Being inland and well off the coast, Haynes homes don't face the salt-air corrosion that plagues seaside suburbs, so standard units hold up well here. Summer heat through this part of Perth is the real driver, which is why correct sizing and a clean, efficient install pay off. Whether it's a first system in a new build or air conditioning Haynes owners are upgrading from a tired old unit, we focus on tidy pipe runs, a properly rated circuit and a quiet, well-positioned outdoor unit.

“Phenomenal service provided by Matt! The works was done on schedule and to a professional standard. The price was also very reasonable for the works done. I highly recommend for anyone looking to get aircon work done, and I wish Otter Air Conditioning the best for their future endeavours.”
