Housing in Mosman is grand. Big Federation and interwar homes on established blocks, plus apartment buildings near the village and toward the harbour. The houses usually suit ducted, the apartments need a split or multi-head with strata sign-off.
About Us

Air Conditioning in Mosman

Mosman homes are some of the nicest on the lower North Shore, and the air con has to suit them.

What system suits a Mosman home. For a large Federation or period home, ducted is almost always the answer if the roof space allows, kept discreet with slimline grilles. A big 4 or 5 bedroom home runs a 14 to 16kW system with 8 to 10 zones. Apartments around the village need a split or multi-head, and strata controls where the outdoor unit goes, so we sort that first. Use the sizing calculator for a rough kW figure, or the ducted cost calculator for a ballpark. To compare running costs and star ratings, the government energy rating site is a good reference. We also cover Manly and Chatswood across the lower North Shore.

Air Conditioning Repairs in Mosman

We do repairs across Mosman Monday to Friday. The common ones here are ageing ducted systems losing capacity in older homes, outdoor units worn by the harbour air, and splits low on gas. Ben handles the diagnostics. You pay a call-out, we find the fault, then quote the fix before we touch it. See our air conditioning repairs page for how it works.

Frequently Asked Questions

Air Conditioning FAQs - Mosman

Usually ducted, kept discreet with slimline grilles so it does not spoil the ceilings. A big home runs a 14 to 16kW system with 8 to 10 zones. If the roof space is tight, a multi-head split is the fallback.

For a large home you are typically looking at $9,500 to $12,500 installed, more for 16kW with lots of zones. You get a written quote before anything is ordered.

Yes. Apartments take a split or multi-head, and strata controls the outdoor unit spot, so we check that with the building before we quote.
