2kW split system installed cost in Perth
$1,490 – $2,190 inc GST, supply & installed
Typical range for a premium-brand unit on a standard back-to-back install. Our value option comes in under it — every live price is in the table below.
The smallest splits we install — 2.0 to 2.2kW — are for genuinely small spaces: a nursery, a study, a single small bedroom up to about 13 m². They're the cheapest units to buy and to run, and the smaller Daikin sizes idle at a near-silent 19 dB(A), which is why they end up over so many cots. The one mistake to avoid is fitting one to a room that really wants a 2.5kW — an undersized unit runs flat-out on a hot afternoon and never quite gets there.

What moves the price inside $1,490 – $2,190
The bottom of the range is a standard back-to-back install, which includes:
- The indoor head and outdoor unit, mounted, levelled, and secured
- Up to 3 metres of insulated refrigerant pipework in neat trunking
- Electrical connection to a suitable existing circuit, with an isolating switch at the outdoor unit
- Condensate drain run to ground level
- Standard outdoor mounting (blocks at ground level, or a wall bracket where specified)
- Vacuum, pressure test, and refrigerant charge to the manufacturer's spec
- Full run test, commissioning, remote demo, and the compliance paperwork
Long pipe runs, two-storey mounting, awkward access and brand tier lift it from there. The full anatomy — with worked examples — is in our Perth split system cost guide, or try the cost calculator for your setup.
2kW split systems — common questions
How much does a 2kW split system cost installed in Perth?
$1,490 – $2,190 supply and installed (inc GST) for a premium-brand unit on a standard back-to-back install. The bottom of that range is an easy wall and a mid-tier premium unit; the top is a flagship unit or a more involved install. Our value-tier option (Midea Athena) comes in under it, and large-capacity units above it — the exact live prices for every unit are on this page, and every quote is fixed before work starts.
What size room does a 2kW split system suit?
up to 13 m² — nursery, study, small bedroom. Insulation, ceiling height and window orientation shift the answer at the margins, which is why we confirm sizing at a free quote rather than guessing from floor area alone.
Does a 2kW split system need new electrical work?
Usually not — at this size the unit can often run from a suitable existing circuit if it's compliant and has capacity. We check the switchboard as part of the free quote. If a dedicated circuit is needed, we run it in-house — we're dual-licensed in aircon and electrical.

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.”
