Split System Air Conditioning means Room-by-Room Comfort
How Split Systems Work
Split systems are simple, efficient, and perfect for controlling individual rooms.
- There is an indoor component to distribute air.
- There is an outdoor unit housing the compressor and condenser.
- The two units are connected by refrigerant pipes that move heat in or out.
Inverter technology adjusts compressor speed for steady comfort, lower energy use, quieter operation, and longer system life.
For multiple rooms, multi-split systems connect several indoor units to one outdoor unit for precise zone control.

Frequently Asked Questions
Your Split System Air Conditioning Questions, Answered.
How do I choose the right size split system?
Choosing the right size split system air conditioner is critical for efficiency and comfort. A unit that is too small won’t cool effectively on the hottest days, while a unit that is too large will cycle on and off too frequently, leading to poor dehumidification and wasted energy.
We determine the correct size by calculating the cooling capacity required, which is measured in kilowatts (kW).
Key factors considered by our COYCO Electricians are:
- Room size (floor area and volume)
- Environmental factors (heat load through windows, sun exposure)
- Usage factors (occupants, appliances, room function)
As a general reference:
- Up to 20m² (small bedroom or office) → 2.5kW unit
- 20–40m² (living room or larger bedroom) → 3.5–5kW unit
- 40–60m² (open-plan area) → 5–7kW unit
Can split systems be used for heating too?
Yes! Reverse-cycle split systems offer both heating and cooling, making them a year-round solution that’s more energy-efficient than conventional electric heaters.
How much does a split system air conditioning installation cost?
In Perth, installation costs typically range from $600 to $1,500, depending on the unit size and complexity of the installation. Contact us for a detailed quote tailored to your space.
How long do split system air conditioners last?
With proper care and maintenance, most split system air conditioners last around 10–15 years. If your system is struggling to cool or making unusual noises, it may be time for repairs or a replacement. Learn more about our air conditioning repair services.
Do split systems improve indoor air quality?
Yes. Many modern units include advanced filters that trap dust, pollen, and other allergens. Some also have dehumidifying features, which help reduce mould and improve overall air quality.
Can I use a split system in multiple rooms?
A single split system is best suited for one room or open space. For multiple rooms, a multi-split system allows several indoor units to connect to one outdoor unit, giving you control across different areas.
How often should I service my split system air conditioner?
To keep your split system running efficiently, it’s recommended to have it serviced once a year. Regular servicing helps maintain performance, improves energy efficiency, and prevents costly breakdowns. Learn more about our air conditioning maintenance services.
