5MXM48AVJU9

Daikin 48,000 BTU 4 Ton
Multi-Zone
Ductless Heat Pump

The 5MXM48AVJU9 is a Daikin regular (standard) multi-zone outdoor heat pump designed to connect to up to five indoor units. It’s the “max flexibility” option in this standard multi lineup — one condenser supporting a full set of zones across a home.

 

This model is best when you truly need five separate comfort zones — for example: a main living area, multiple bedrooms with different temperature preferences, a basement, and a bonus room that never balances well. It can also be a great solution for homes where you want to avoid ductwork changes, but you still want full-room control and a clean outdoor look.

 

With five zones, we’re extra disciplined:

- We don’t oversize indoor heads “just in case.”

- We keep head selection intentional (you can mix types).

- We plan piping and installation so service access and long-term reliability are protected.

The goal is a system that’s quiet, stable, and easy to live with — not one that’s constantly fighting itself.

We confirm sizing and pricing on site – no pressure, no upsells.

Technical documents

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.
