FAQs

A split system air conditioner operates using two interconnected units. The indoor unit extracts warm or cool air from your room. This air is then transferred to the outdoor unit, where it undergoes a heat exchange process to either cool it down or warm it up. The conditioned air is subsequently returned to your home by the indoor unit.

Absolutely! Reverse cycle air conditioners are versatile units that can heat or cool your home. By reversing the refrigeration cycle, they can efficiently provide warmth during colder months and cool air during warmer periods, ensuring optimal comfort throughout the year.

While initially more costly, reverse cycle air conditioners offer superior heating efficiency compared to other heating methods. Their lower energy consumption makes them a more economical choice than portable electric, ceramic, and fan heaters. To maximise energy efficiency, consider the energy rating of the air conditioner before purchasing.

To optimize your air conditioner's efficiency, use energy-saving features like 'Eco' mode and motion sensors. Adjust temperature settings mindfully, as each degree can significantly impact energy consumption. Close doors and blinds to enhance the cooling or heating effect. For smart air conditioners, leverage app features to monitor usage, set schedules, and optimise energy consumption.

A smart air conditioner offers several benefits, including remote control, energy efficiency, voice control, and scheduled operation. While it may have a higher upfront cost and require a stable internet connection, it can significantly enhance your home comfort. Consider your budget, lifestyle, home layout, and tech-savviness before deciding if a smart air conditioner is the right choice for you.
