  • What size air conditioner do I need for my home?

    Choosing the correct size air conditioner is crucial for effective and efficient cooling. The size of an air conditioning unit is typically measured in BTUs (British Thermal Units) or kilowatts (kW). 


    Several factors determine the right size, including the room’s square footage, ceiling height, insulation, window size and amount of sunlight. For instance, a small room of 10-15 square meters might only need a 2.5 kW unit, while a larger living space of 40-50 square meters could require a 7-8 kW unit. 


    An undersized unit will struggle to cool the space effectively, leading to increased wear and tear, while an oversized unit may cool too quickly without dehumidifying properly. Consulting with an HVAC professional can help accurately assess your cooling needs based on your home’s unique characteristics.

  • What is the difference between a ducted and split system air conditioner?

    Ducted and split system air conditioners serve different purposes and suit different types of spaces. A split system air conditioner cools a single room or small area, with the indoor unit mounted on a wall and the outdoor unit positioned outside. These systems are ideal for individual rooms, as they provide targeted cooling and are generally more affordable.


    In contrast, a ducted system is a centralised cooling solution that distributes conditioned air throughout multiple rooms via ductwork, typically installed within the ceiling or walls. Ducted systems are more discreet, as only vents are visible, and allow for zoned cooling, where specific areas of the home can be controlled independently. While ducted systems are more expensive to install, they are highly effective for whole-home or large commercial space cooling.
