Features

All star performer
Serene Series 2 is one of Actron Air’s most energy efficient air conditioners yet, with our 2.65kW model reaching the highly sought after 7 star energy rating*.
*7 star energy rating applies to WRC-026DS / WRE-026DS combination. Rated under new climate zone SEER rating.

More cooling in extreme heat
With a market-leading operating range of up to 60°c, Serene is guaranteed to keep working in hotter temperatures. Not only that, Serene is also able to maintain far better capacity in extreme heat than comparable systems, which provides you with more cooling comfort right when you need it most.

R32 for efficient energy performance
Serene uses R32 refrigerant – a gas that offers a low Global Warming Potential – reducing its impact on our environment.

AC vs DC for rockin’ efficiency and performance
Serene uses more energy efficient Direct Current (DC) inverter technology in its inverter compressor, indoor fan and outdoor fan. While some competitors use less efficient AC technology, or combinations of both, we choose DC technology as it can make a huge difference to your electricity bill. With an impressive 25 frequency stages, our DC inverter compressor is up to 35% more efficient than AC technology, while Serene’s DC outdoor fan with five speed settings is up to 40% more efficient. The result is improved efficiencies overall, as well as optimal cooling performance at high and low ambient temperatures, and quieter operation on part load.

What our Experts Think

• Strong energy performance: Delivers efficient cooling and heating with high EER/COP ratings typical of Serene Series 2 systems
• Ultra-quiet operation: Designed for bedroom comfort with very low noise levels in sleep mode and smooth airflow control
• Smart airflow distribution: 3D swing function ensures even cooling and heating across the entire room
• All-season reverse cycle: Provides reliable cooling in summer and heating in winter with wide operating range
• Energy-saving smart features: Includes Eco Mode (up to ~65% reduced energy use), Boost Mode, and Proximity Sensor for adaptive operation
• Health-focused air care: Integrated ioniser and filtration system helps reduce dust, allergens, and odors
• Australian climate ready: Built to handle extreme temperature conditions while maintaining performance stability

Q&A

Q: What is the ActronAir WRE-035DS air conditioner?
A: The ActronAir WRE-035DS is a 3.5kW wall-mounted split system indoor unit from the Serene Series 2, designed for efficient cooling and heating when paired with a compatible outdoor unit.

Q: What size room is it suitable for?
A: It is ideal for small to medium rooms such as bedrooms, studies, or small living areas, depending on insulation and climate conditions.

Q: Does it provide both cooling and heating?
A: Yes, it is a reverse-cycle system, delivering cooling in summer and heating in winter when connected to its matching outdoor unit.

Q: Is it energy efficient?
A: Yes, it uses DC inverter technology and R32 refrigerant, which helps reduce power consumption and improves overall efficiency compared to older systems.

Q: How does it distribute air?
A: It features multi-directional airflow and adjustable fan speeds, helping maintain consistent comfort throughout the room.

Q: Is this a complete air conditioning system?
A: No, this is an indoor unit only, meaning it must be installed with a compatible ActronAir outdoor unit to operate.

Q: Why choose a 3.5kW split system like this?
A: It offers efficient room-specific climate control, quiet operation, and lower running costs, making it a popular choice for bedrooms and compact living spaces.

Maintenance Tips

• Clean filters every 2–4 weeks: Maintains strong airflow, quiet operation, and high energy efficiency (critical for ~3.5kW room coverage).
• Wipe indoor unit panels & louvers: Prevent dust buildup that can block airflow and reduce cooling performance.
• Check condensate drain: Keep clear to avoid water leaks, dripping, or ceiling damage.
• Run dry/fan mode occasionally: Helps reduce internal moisture and prevents odor or mold in the indoor coil.
• Ensure airflow is not blocked: Keep furniture and curtains away from return/supply airflow paths for even temperature control.
• Listen for abnormal noise: Rattling or weak airflow usually signals dirty filters or fan obstruction.
• Avoid constant extreme settings: Running max cooling continuously increases power use and system wear.
• Annual professional service: Clean coils, check refrigerant levels (R32), and verify electrical safety for optimal performance and lifespan.
