Air conditioning for Bridgeman Downs homes

Larger Bridgeman Downs homes are where aircon quotes get wildly different. One installer wants to swap the unit and keep the old ducting, another wants to redo everything, and a third suggests five wall splits. Each one costs you a morning on site.

That’s the bit we’ve already done. We send one vetted installer who does larger ducted jobs, checks the whole system and quotes it upfront in writing.

Bridgeman Downs is known for bigger blocks and larger family homes than many northside suburbs, with plenty of four- and five-bedroom houses, some on acreage-style lots, and a mix of single and double storey designs from the 1980s onwards.

Larger homes are where ducted air conditioning really earns its keep. Rather than five or six separate split systems, a properly sized and zoned ducted system can cool bedrooms at night and living areas by day from one controller. Many homes here already have ducted systems installed 15 to 20 years ago that are now due for replacement, sometimes with ductwork that needs replacing too.

Bigger blocks also mean more outbuildings. Granny flats, home offices, studios and pool rooms are common, and they usually suit their own split system on a separate circuit rather than being tacked onto the main system.

Power supply and solar on larger homes

Some larger homes have three-phase power, which can open up a wider range of large ducted units. Others are single-phase, which is fine for most residential systems but worth confirming for bigger capacities. The contractor will check your supply and switchboard as part of the quote.

If you have rooftop solar, running your air conditioning during the day while the panels are generating can make good use of that power. Many controllers let you schedule cooling in the afternoon so the house is comfortable when everyone gets home.

Common questions

Bridgeman Downs air conditioning FAQs

What size ducted system does a large Bridgeman Downs home need?

Larger four- and five-bedroom homes often need somewhere in the region of 14 to 20 kW or more, but floor area alone isn’t enough to size a system. Ceiling heights, insulation, glazing, orientation and how many zones run at once all matter. Ask the contractor for a heat-load calculation, not a rule of thumb.

Should I replace my old ductwork along with the unit?

If the ducting is 15 to 20 years old, it’s worth having it inspected. Older flexible ducting can sag, tear or lose insulation, which wastes cooling into the roof space. Replacing ductwork costs more up front but can noticeably improve performance. The contractor should tell you whether reusing it is sensible.

Can a granny flat run off the main house aircon?

Usually it’s better to give a granny flat or studio its own split system. It keeps running costs separate, avoids long duct runs and lets the occupant control their own temperature. The electrical side needs a suitable circuit, which may come from the main board or a sub-board in the building.
