Mitsubishi Electric City Multi VRF installation across Sydney.

City Multi, Mitsubishi Electric's VRF range

City Multi is Mitsubishi Electric's VRF range: one outdoor system serving many indoor units, with each room or area on its own control. It covers heat pump systems, which heat or cool, and heat recovery systems, which can heat some areas while cooling others.

We design and install City Multi for homeowners, builders, developers and commercial clients across Sydney, and we can work to a City Multi specification from your architect or mechanical consultant.

What we install

• City Multi heat pump systems for homes and commercial spaces.
• City Multi heat recovery systems for buildings that need heating and cooling at the same time.
• City Multi indoor units: concealed ducted, ceiling cassette, wall-mounted and floor units.
• City Multi controls, from individual room controllers to central control.

Designed, installed and commissioned by one team

1. Plans and design. Send us the architectural drawings, or the mechanical design if a consultant has prepared one. We size the system room by room, select the outdoor and indoor units, and lay out the refrigerant pipework, branch joints, drainage and controls.
2. Written quote and scope. Equipment, indoor unit types and locations, outdoor plant position, power and drainage requirements, and exactly what is and isn't included, so there are no surprises at handover.
3. Coordination before rough-in. Ceiling and bulkhead space, plant location, penetrations, condensate drainage, electrical supply and controller positions are agreed with you and your trades before the frame is closed.
4. Rough-in. Refrigerant pipework brazed under nitrogen, insulated and supported, then pressure-tested. Drains and control cabling run at the same time, booked around your program.
5. Fit-off. Indoor units, grilles and outdoor plant installed after plaster and paint, with a clean, tidy finish.
6. Commissioning and handover. The system is evacuated, charged, started and checked against the manufacturer's requirements, every zone and controller is set up, and the owner is shown how to use it.
7. Servicing. We stay on as the service contact, so the owner and the builder have one number to call.
