4MXM36AVJU9
Daikin 36,000 BTU 3 Ton
Multi-Zone
Ductless Heat Pump
The 4MXM36AVJU9 is a Daikin regular (standard) multi-zone outdoor heat pump designed to connect to up to four indoor units. It’s the next step up when you want more coverage — multiple rooms or floors — without installing multiple outdoor units.
This unit typically makes sense when a home has several comfort problem areas that need independent control: a couple bedrooms, a main living space, and a basement; or a main floor plus three bedrooms; or a mix of wall units and concealed options where aesthetics matter. It can also be a smart way to keep the outside of the home clean — one condenser instead of a row of single-zone units.
At four zones, the design details become even more important:
- Shared capacity means the outdoor unit distributes output based on demand.
- Indoor unit selection matters (wall vs floor vs ceiling vs slim duct).
- Piping limits and layout planning matter (total length, per-room runs, height differences).
Our job is to design it so it feels simple and predictable for the homeowner — not finicky.
We confirm sizing and pricing on site – no pressure, no upsells.

Key features of the MXM Multi Zone Heat Pump
- Key features of Daikin Standard Multi-Zone (2MXM / 3MXM / 4MXM / 5MXM)
- One outdoor unit, multiple zones: supports up to 2 / 3 / 4 / 5 indoor units depending on the model.
- Independent zone control: each indoor unit can be controlled separately for room-by-room comfort.
- Cleaner exterior footprint: fewer outdoor units compared to installing multiple single-zone systems.
- Flexible indoor unit options: can pair with common indoor styles (wall mounts, floor consoles, ceiling cassettes, slim ducts), depending on the matched system design.
- Inverter-driven modulation: ramps output to reduce on/off cycling and maintain steadier indoor temperatures.
- Shared-capacity reality (important): total outdoor capacity is shared across zones when multiple areas call at once — design and sizing matter.
- Installation limits matter: total piping length, per-room runs, and height differences must be planned correctly for performance and reliability.
- Peak Comfort install standard: correct design, clean line routing, pressure test + evacuation, and start-up/commissioning with real measurements — no guesswork.
- No upsell / no scare tactics: we recommend what fits the home and usage, explain tradeoffs plainly, and price it clearly.
