FAQ
What size air conditioner do I need for my home?
Choosing the right size air conditioner for your home depends on several factors including room size, ceiling height, insulation, number of windows, and local climate. In general, for a standard room with average insulation, you’ll need around 1 to 1.5 kilowatts (kW) of cooling power per 10 square metres. For example, a 20m² bedroom might need a 2.5kW unit, while an open-plan living area of 60m² could require a 7kW unit or more. However, other factors—like sun exposure, number of occupants, and whether the space is upstairs or downstairs—also influence the ideal capacity. An undersized unit will struggle to cool effectively, while an oversized unit may short-cycle and waste energy. For the most accurate recommendation, a licensed technician should conduct an on-site assessment.
What’s the difference between split system and ducted air conditioning?
Split systems are single-room air conditioners made up of one indoor and one outdoor unit, making them ideal for bedrooms, studies, and living rooms. They’re cost-effective, easy to install, and efficient for targeted cooling or heating. Ducted systems, on the other hand, are designed to cool or heat an entire home using a central unit and a network of ducts in the ceiling or floor. Ducted systems are more discreet and offer zone control, which allows users to cool certain rooms while leaving others off. While the upfront cost of ducted air conditioning is higher, it offers a more seamless look and comprehensive climate control across the home. The choice between the two depends on your layout, budget, and how many rooms you want to cool.
How often should home air conditioning units be serviced?
Residential air conditioning systems should be serviced at least once a year to maintain efficiency, prevent breakdowns, and ensure healthy indoor air quality. In Darwin’s humid climate, more frequent servicing—every 6 to 9 months—may be necessary due to higher dust, moisture, and mould risks. A typical service includes cleaning the filters and coils, checking refrigerant levels, inspecting electrical components, and ensuring the drain is clear to prevent water leaks. Regular maintenance also helps identify minor issues before they become costly repairs and ensures the unit continues to operate at peak performance. Keeping up with servicing not only extends the life of your air conditioner but may also be a condition of your warranty.
