Mitsubishi Electric installer, Melbourne’s south-east.

The 2.5 kW MSZ-AP is our workhorse bedroom unit — quiet at 21 dBA on low fan, sips power on standby, and the parts pipeline is genuinely never a worry. If you want a single unit in a kid's bedroom, this is what we install.

The 3.5 kW is the sweet spot for a big master bedroom or a smaller open-plan. Same reliability as the 2.5, same low-noise profile, just enough extra capacity to handle the doors-open scenario without running at 100% all summer.

The 5.0 kW MSZ-AP is our default recommendation for an open-plan living zone in a modern brick-veneer family home. Big enough to handle a Melbourne heatwave with the doors open, small enough that it doesn't cycle constantly on a mild day.

The step between the 5.0 and the 7.1 — for the awkward room size that's between a normal living and a proper great-room. Cathedral ceilings or a big north-facing glass wall usually push us up to the 6.0.

The 7.1 is the biggest wall-mounted unit we'd typically spec — beyond this, ducted or multi-head makes more sense. For a big north-facing living zone in Berwick or Officer, this is usually the answer.

The biggest wall split Mitsubishi makes. Beyond this size a ducted system usually delivers better airflow distribution — but for a large single space where you don't want ducting, this is the pick.

The LN is the Design-series MSZ-AP — same reliability underneath, flush glass front, matte finish. About $500 more than the AP but people who care about the look on the wall don't mind the premium.

The 3.5 kW Design — our recommendation when the customer specifies a matte black or ruby red unit to match a feature wall.

The Design 5.0 goes into a lot of high-end Berwick and Officer new-builds where the interior designer has specified a matte finish. Same 5.0 kW performance as the AP, just wrapped in glass.

The EF is a mid-tier design option between the AP and the LN. Sleeker face than the AP but without the LN's glass premium.

3.5 kW in the EF trim — the split we recommend when someone wants the design cue without the LN price step.

The FH-series is the only Mitsubishi that holds rated heating capacity down to -15°C outdoor. It's not overkill for the Dandenong Ranges — a normal MSZ-AP loses ~30% of its heating capacity at 0°C, the FH doesn't. We spec it for every Cockatoo / Emerald / Gembrook install.

3.5 kW cool, 4.8 kW heat at -15°C — the FH35 punches above its weight when it's a cold morning in the ranges. Costs more up-front but pays for itself in comfort inside a couple of winters.

5.0 kW in Hyper Heating trim — the pick for a large hills-country living space where cold-morning performance genuinely matters.

The 2F is the smallest multi-head — one outdoor condenser feeding two indoor heads. Ideal for an apartment where you only have one balcony spot for the outdoor unit.

The 3F is our most-installed multi-head. One outdoor unit, three bedrooms — cleaner externally than three separate splits, and the individual room controllers give proper zone control.

The 4F is our recommendation for a family home that's outgrown ducted zones and wants individual per-room setpoints. Fewer outdoor units, per-room controllers, one refrigerant loop to service.

The 5F is the biggest multi-head Mitsubishi makes. Five heads, one outdoor unit. Beyond this we'd move to ducted.

The PEAD-M is our default ducted indoor unit. Mid-static means it has enough duct capacity for a typical 3-4 zone family home without oversized fan power. Pairs with the PUZ outdoor and any Mitsubishi zone controller.

The PEA-RP is the high-static big brother — necessary when you've got long duct runs or a double-storey with six or more zones. Enough fan power to actually deliver rated flow to the furthest zone.

The SEZ-KD is a slim-line ducted indoor that fits into a 200mm ceiling void — the pick when the ceiling cavity is too shallow for a normal PEAD. Common in the older Berwick and Officer weatherboards.

The SLZ-M is the 600×600 compact cassette — the standard for small commercial and medical fit-outs. Slots into a suspended ceiling tile grid without cutting, 4-way airflow.

The PLA-M is the bigger 840×840 cassette for larger commercial spaces. Better throw distance, better for rooms with higher ceilings.

The MFZ-KJ sits on the floor like an old radiator — the answer when there's no wall space at high level, or the customer wants direct floor-level warmth.

The PAR-42 is the physical touchscreen wall controller — the option for anyone who doesn't want to reach for their phone to change the temperature. Standard on our commercial cassette installs.

MELCloud plugs into any Mitsubishi indoor unit and adds phone + web control. We fit it as standard on new installs — you'd rather have it and not need it than the reverse.
