Is it better to have a combination of ducted heating/cooling and RCACs or switch to full RCAC?

  1. Reverse cycle (heating + cooling) systems cost about the same as cooling-only ones, so there’s no reason to bypass that added capability. 
  2. If by ducted heating you mean gas, this is a much more expensive option with ongoing costs.
  3. It is better with a new home to start with installing stand-alone RCACs. 
  4. Many people considering a reverse-cycle split system ask whether it provides the same warmth as a ducted or hydronic heating system. They worry that the air movement in a reverse-cycle system might have a slight cooling effect on the hot air, thus making the split system run at a higher setting for the same comfort level. While all convective heaters have a very subtle cooling effect, many reverse-cycle air con manufacturers have improved their product design to minimise it.
  5. For instance, many air conditioners now come with more (and wider) air outlets that circulate air at slower speeds. Many also direct airflows over the walls, floor, and/or ceiling (instead of blowing air directly onto occupants). This allows air to move further across the room at a slower pace, which will effectively warm (or, in summer, cool) your room at a low setting. 
  6. Finally, split-system aircons are ideal for people with allergies or asthma — many include high-quality air filters. Ducted systems are inherently dusty.
