8 kWCarrier Indigo 8kW Split System
The 8 kW Carrier Indigo Split System cools a room of up to about 57 to 67 square metres as a guide. That is from Mitsubishi Heavy Industries' sizing chart for an insulated room: the larger figure if it faces north, the smaller if it faces east. Sun exposure, ceiling height and insulation move those figures, 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 8 kW options, see every 8kW split system ranked by running cost, or ask about supply and installation.
About $579 a year at the current Sydney median electricity rate: $223 of cooling plus $356 of heating, from the official GEMS test figures.
The Carrier Indigo 8kW uses 673 kWh per year for cooling and 1076 kWh per year for heating, based on official energy label test data for Sydney's climate zone. These figures show how much electricity the system consumes under standard test conditions.
The unit carries a 3-star energy rating for cooling and 2.5-star rating for heating under the zoned energy label. Its rated cooling efficiency (AEER) is 3.40 and heating efficiency (ACOP) is 3.56. The system uses R32 refrigerant. Your actual running costs will depend on your local electricity rate and how you operate the system.
