Rinnai Split System Air Conditioning

RDS Electrics installs Rinnai split system air conditioners for residential and commercial customers who demand high-performance, all-season heating and cooling solutions in Australia. Rinnai inverter split systems offer precise temperature control, quiet performance, and year-round comfort for bedrooms, living areas, and workspaces.

Why Choose Rinnai with RDS Electrics

Rinnai inverter split systems employ sophisticated DC inverter technology that varies compressor speed according to changing room conditions, which helps to maintain a more consistent temperature with lower energy bills than fixed-speed compressors. Reverse cycle functionality provides strong cooling during hot summer months and adequate heating during cooler seasons, making Rinnai an attractive all-season solution for most residential applications. When we properly design and install these systems, you can enjoy reliable comfort, controlled operating costs, and a sleek, modern wall-mounted appearance.

Comfort, Functionality, and Room Sizing

We size each Rinnai split system to the individual room, taking into account floor area, ceiling height, insulation, and window orientation. The Rinnai split system product line offers capacities from small bedrooms and studies to larger open-plan living areas, allowing us to avoid the drawbacks of undersized units that work too hard in hot weather and oversized units that short-cycle. Many Rinnai models offer additional functions such as long-throw air discharge (up to approximately 15 meters for selected J Series capacities), sleep mode, turbo/boost mode, timers, and fine temperature control, which enable comfortable, even temperature distribution with low noise levels.

Rinnai Series and Formats We Install

RDS Electrics deals with the major Rinnai split and multi-split ranges, so we can match performance and configuration to your space. This includes J Series wall splits for everyday space heating and cooling, JX Series inverter splits with Wi-Fi and voice control, and T Series and PB Series inverter splits where particular performance or functionality requirements are best met by your project. We also offer the CJ and CJ1 series, where available, cassette systems for ceiling-suspended commercial or open-plan space heating and cooling, and floor console units for low-wall installations or where wall mounting is impractical.

Where your project requires multiple indoor units served from a single outdoor unit, we design Rinnai inverter multi-split solutions using slim-ducted indoor units, wall-suspended units, compact cassette units, or floor console multi units, depending on room type and ceiling or wall constraints. Throughout your Rinnai split system installation, we can select J Series, JX Series, T Series, PB Series, CJ/CJ1 series, cassette, floor console, or multi-split systems so that each space receives a suitable capacity and type.

Installation, Maintenance, and Service

When you choose Rinnai split systems from RDS Electrics, we will carry out system selection, correct sizing, correct electrical installation, installation of the refrigerant lines, and system startup. We also install indoor units for better airflow and less draught, and outdoor units for adequate ventilation, less noise transmission, and easier future maintenance. To keep your Rinnai split systems running efficiently and effectively, we can usually arrange a professional service visit annually in a residential setting, which includes filter and coil cleaning, checks on the refrigerant system, checks on the electrical system, and checks on operating conditions and airflow so that your Rinnai split systems continue to operate effectively.
