Who the Panasonic RZ 3.5kW is for
At 3.5kW the RZ hits the most popular size in Perth at the best premium-brand price on our list. It's the unit we suggest when someone says 'good brand, sensible money' — a standard bedroom or small living room covered without paying for features you won't use.
Sized right, 3.5kW comfortably covers around 23 m² in Perth conditions — standard bedroom, small living. Every RZ has a Quiet mode that drops fan speed and noise for bedrooms and night running. If you're between sizes, we'll tell you straight at the quote which way to go — an undersized unit runs flat-out and wears early, an oversized one short-cycles.
The RZ is Panasonic's workhorse wall split — premium build without the premium extras. You get the same compressor and chassis quality as the flagship Z series, a three-in-one anti-bacterial filter, a dedicated Quiet mode, and Panasonic's 5-year warranty, at the sharpest price we sell a premium brand for. Wi-Fi control is optional rather than built in — for a lot of rooms that's money better kept in your pocket.
Installed price
What $2,075 includes
The from-price is a standard back-to-back install — indoor and outdoor unit on opposite sides of the same wall — and it includes the whole job, not a stripped-down teaser:
- 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
What lifts a quote above the from-price: long pipe runs, two-storey or high mounting, tricky access. The full breakdown is in our Perth split system cost guide, or get a number for your wall with the cost calculator.
The Panasonic RZ range
Why we fit the Panasonic RZ
Anyone who wants premium-brand reliability at the best price and doesn't need app control or air purification built in.
Premium guts, sharper price
Same inverter compressor platform as the flagship Z series — the savings come from trimming extras, not quality.
Anti-bacterial filter
Three-in-one anti-allergen, anti-virus and anti-bacterial filtration, easy to remove for regular cleaning.
Quiet mode
A dedicated Quiet setting drops fan speed and noise for bedrooms and overnight running.
Optional Wi-Fi
Add Panasonic's network adaptor later if you want app and voice control — it's a plug-in accessory, not a different unit.

Other Panasonic RZ sizes
Panasonic RZ 3.5kW — common questions
How much does the Panasonic RZ 3.5kW cost installed in Perth?
From $2,075 inc GST, supply and installed as a standard back-to-back install. That covers the unit, mounting, up to 3 metres of pipework, the electrical connection and isolator, and full commissioning. Longer pipe runs, height access or switchboard work lift the price — you get an exact fixed quote free before any work starts.
What size room does the Panasonic RZ 3.5kW suit?
As a Perth rule of thumb, 3.5kW of cooling comfortably handles a room of around 23 m² — standard bedroom, small living. Ceiling height, insulation, and big west-facing windows shift the answer, which is why we always confirm sizing at the quote.
Can the Panasonic RZ 3.5kW run off an existing circuit?
Often, yes — at 3.5kW it can usually share a suitable existing circuit if it's compliant and has capacity, which keeps the install cost down. We check your switchboard as part of the free quote and tell you either way before any work starts.
What warranty does the Panasonic RZ 3.5kW come with?
Panasonic 5-year parts and compressor warranty, plus our own workmanship warranty on the installation. Installation by an ARC-licensed tech and a licensed electrician — the same team, on the same job — protects your manufacturer warranty; an unlicensed install is the usual reason a claim gets knocked back.
