We recommend servicing your air conditioning unit at least once a year. Regular servicing helps maintain efficiency, extends the lifespan of the unit, and prevents unexpected breakdowns.

A ducted reverse cycle installation involves installing an indoor unit typically in the roof space, an outdoor compressor unit, and ductwork throughout the home. We handle everything from the initial site inspection and design through to final commissioning and testing.

To improve performance, ensure your filters are cleaned regularly, keep windows and doors slightly to allow air circulation, and have the cooling pads inspected and replaced if worn. Our team can also assess your system for any underlying issues.

The right size depends on the floor area, insulation, ceiling height, and number of windows in your home. As a rough guide, a 2.5kW unit suits rooms up to 20m², while a 6–8kW unit is better for larger-plan areas. Contact us for a free assessment.

Strange noises can indicate various issues — rattling may mean loose components, banging could signal a compressor fault, and hissing often points to a refrigerant leak. If your unit is making unusual sounds, contact us for a prompt diagnosis and repair.

We do both! Otter Air can source and supply the right system for your home or business, as well as handle the full installation. We also install units supplied by the customer if preferred.
