2.5 kWCarrier Indigo 2.5kW Split System
The 2.5 kW Carrier Indigo Split System suits rooms around 16 to 20 square metres as a guide. Sun exposure, ceiling height and insulation move that band, which is why we confirm sizing before we quote.
The Carrier Indigo 2.5kW uses 146 kWh annually for cooling and 281 kWh annually for heating under official GEMS testing in Sydney's climate zone. These figures account for typical residential use patterns and allow you to calculate your running costs based on current electricity rates. The system achieves a 6-star energy rating for cooling and 3.5 stars for heating, both zoned to Sydney conditions.
The Carrier Indigo 2.5kW delivers an AEER (cooling efficiency) of 4.98 and an ACOP (heating efficiency) of 5.16. These ratings indicate how much cooling or heating output you receive per unit of electricity consumed. The system uses R32 refrigerant, a modern low-GWP option. Combined with the verified annual energy figures, these efficiency ratings help you understand the unit's operating performance in your home.
