Daikin Inverter Ducted 12.5kW: your questions
How much does a 12.5kW ducted system cost installed?
Installed cost for a ducted system depends on the number of zones, duct runs and outlets, roof space access, whether the outdoor unit needs single or three phase power, and any switchboard work. That is why we quote each home individually rather than publishing a flat rate. Call or email with your floor plan or photos, and we book a site visit if the job needs one, then give you a fixed quote in writing before any work starts.
What size home does a 12.5kW ducted system suit?
As a guide, 12.5kW of cooling covers roughly 81 to 100 square metres of conditioned area, typically run as zones so you are not cooling the whole home at once. Ceiling height, insulation and glass move that band, so we confirm sizing from your floor plan before anything is ordered. Our capacity calculator gives you a quick starting point.
