Frequently Asked Questions

  • How often should a split system air conditioner be serviced?

    It’s recommended to service a split system at least once a year, ideally before the peak summer season. In Darwin’s tropical climate, dust, humidity, and heavy use can strain your system. A professional service includes cleaning filters, checking refrigerant levels, inspecting electrical components, and ensuring the unit runs efficiently. Regular servicing not only improves cooling performance but also reduces energy costs and helps prevent unexpected breakdowns.

  • What size split system air conditioner do I need?

    The size of your split system depends on the room’s dimensions, insulation, ceiling height, and how much natural heat enters through windows or doors. For example, a small bedroom might need a 2.5kW unit, while a large open-plan living area may require 7kW or more. Choosing the wrong size can lead to inefficient cooling, higher bills, and unnecessary wear on the system. An expert assessment ensures you get the right balance of comfort and efficiency.

  • What are the benefits of a split system compared to other types of air conditioning?

    Split systems are a popular choice because they are energy-efficient, quiet, and versatile. Unlike ducted systems, they allow for individual room control, which means you only cool the spaces you use. They’re also quicker to install, require less invasive building work, and are available in a wide range of capacities to suit different room sizes. For Darwin homes and businesses, split systems provide cost-effective cooling that can be tailored to both small and large spaces.
