5 kWCarrier Indigo 5kW Split System
The 5 kW Carrier Indigo Split System suits rooms around 32 to 40 square metres as a guide. Sun exposure, ceiling height and insulation move that band, which is why we confirm sizing before we quote.
Part of the Carrier Indigo Split System range, Carrier's split system line, in 6 sizes. Running costs below use the Sydney median rate; the Eastern Suburbs and Western Sydney pages cost systems on their own network tariffs. Check the size against your rooms, compare it with other 5 kW options, or ask about supply and installation.
About $311 a year at the current Sydney median electricity rate: $108 of cooling plus $203 of heating, from the official GEMS test figures.
The Carrier Indigo 5kW uses 373 kWh per year for cooling and 703 kWh per year for heating, based on official GEMS testing in Sydney's climate zone. These figures let you calculate running costs using your current electricity rate. The system achieves a 4-star energy rating for cooling and 2.5 stars for heating under Sydney conditions.
Efficiency is measured by AEER (cooling) and ACOP (heating) ratings. The Indigo delivers an AEER of 3.67 and ACOP of 3.66. It uses R32 refrigerant. Your actual energy consumption will depend on how often you run the system and the temperatures you set.
