FAQ
Daikin Bulkhead: common questions
How much does a Daikin Bulkhead model cost installed?
Typically $6,500 to $10,500 supplied and installed in 2026, depending on size and the job. Under 10 kW: $6,500 to $10,500. Pipe runs, a new circuit or a second storey add to it. Get up to three local quotes for your actual job.
Which is the most energy efficient?
For the average climate zone, the Daikin FDYBA25AV1 (2.5 kW) has the highest cooling rating here at 2.5 stars. Star ratings on the zoned label run to 10, and a star is worth more in a hot zone than a mild one. For cold-climate heating, the Daikin FDYBA35AV1 leads at 2 stars.
What size ducted system do I need?
Most three-bedroom homes land around 10 to 14 kW and four-bedroom homes 14 to 18 kW, but insulation, ceiling height and zoning change it. Our sizing guide explains how installers work it out.
