What ducted jobs has Delta Temp done in Birtinya?
We have replaced and installed ducted systems in Birtinya homes and in business or body corporate buildings. The work covers Mitsubishi Electric and Fujitsu systems, including a home with a large Mitsubishi Electric system and a smaller unit downstairs, plus rustproofing on a replacement.
Birtinya is a newer suburb close to the coast, and the work reflects that mix. A replacement Mitsubishi Electric system went in with rustproofing, and a larger and a smaller Fujitsu ducted unit were replaced for a business or body corporate site. On the home side, one job paired a large Mitsubishi Electric system with an AirTouch 5 control upgrade, and another was a straight ducted installation. Every job starts from the building in front of us, not from a standard package.

How does Delta Temp quote ducted air conditioning in Birtinya?
We book a free site inspection before we quote. We look at the roof space, the zones you want and the size of the home, then give you a fixed quote after the inspection. Most Sunshine Coast homes land between $11,000 and $18,000 installed, depending on home size, zones and roof space.
Larger homes can reach about $22,000. The exact price comes from the inspection, which is why we do not quote ducted work blind. We also check where the return air grille and the ducts can go, because roof space decides a lot in a ducted job. To book the inspection, call 1800 335 828 or visit deltatemp.com.au. We service the Sunshine Coast from Caboolture to Noosa.
How big a ducted system does a Birtinya home need?
We add up the heat load of every zoned room at about 150 W per square metre, then size the system at about 70% of that total. The zones are never all running flat out at once, so the system does not need to cover the full sum.
In practice a 12.5 kW system suits 5 zones, being 4 bedrooms plus an open kitchen, living and dining, or about 120 m2 of zoned rooms. A 14 kW suits 6 zones, the same plus a media room or similar, about 130 m2. The inspection then adjusts for insulation, glass, ceiling height and orientation, so these figures are starting points only. Our Birtinya jobs ranged from 7 kW to 25 kW, which shows how much the building matters.

Can an existing Birtinya ducted system be replaced and given zone control?
Yes. Replacement is a big part of our ducted work, and AirTouch 5 is the zone controller we install. One Birtinya job included an AirTouch 5 upgrade, and one replacement included rustproofing as part of the install.
