Cool. Cozy. Reliable.

A split-system air conditioner is a system made up of two main components:

• An indoor unit that delivers cool or warm air

• An outdoor unit that removes heat from inside your home

These systems use refrigerant to transfer heat, making them an efficient way to control indoor temperature. Because refrigerant gases are involved, installation and servicing must be carried out by a licensed technician to ensure safety and environmental compliance.

• Energy efficiency: Split systems (especially inverter heat pumps) use less electricity because they move heat rather than generate it, making them more cost-effective to run.

• Heating and cooling in one system: Unlike traditional heaters, a split system can both heat your home in winter and cool it in summer.

• Better temperature control: You can set and maintain a consistent temperature, improving comfort throughout the day.

• Lower running costs: Compared to electric heaters, split systems typically cost less to operate over time.

• Quieter and safer: No exposed heating elements or fans blowing hot air, making them safer for homes with children or pets.

The amount of energy a split-system air conditioner uses depends on:

• The size of the unit (e.g. 2.5kW, 7kW, etc.)

• How often it is used

• Your temperature settings

Modern systems are designed to be energy efficient, but incorrect installation or sizing can increase running costs and reduce efficiency. ARC guidance also highlights that poor installation or maintenance can lead to unnecessary costs and environmental impact.

Choosing the correct size system is critical.

Factors include:

• Room size and layout

• Ceiling height

• Insulation and windows

ARC also emphasises that getting expert advice is important, as installing a system that is too large or too small can lead to wasted money and poor performance

KoolnKozy can assess your space and recommend the right system.

If your air conditioner stops working:

• Check power supply and remote batteries

• Clean or inspect filters

• Look for error codes

If the issue continues, contact a licensed air conditioning technician.

ARC strongly recommends using properly licensed professionals, as they are trained to safely diagnose and repair systems that use refrigerants, reducing risk to both your system and the environment.

Old air conditioners must be handled properly because they contain refrigerant gases.

You should:

• Have the unit decommissioned by a licensed technician

• Ensure refrigerants are safely recovered and disposed of

• Consider upgrading to a more energy-efficient system

ARC highlights that refrigerants must be handled and disposed of safely and legally, only by licensed professionals

KoolnKozy can safely remove and dispose of your old system when installing a new one.
