Glenhaven is the quiet end of the Hills and the homes are some of the biggest we work on - established two-storeys and acreage-style places on serious blocks, built properly and kept that way. Ducted is the default here, the systems are large, and the owners expect work that matches the house. Mick has run Hills installs for us since 2009, so this is genuinely home turf.
After air conditioning in Glenhaven? Jay's Air has been doing it since 1991. The typical Glenhaven 4-5 bedder wants 14 to 16kW of zoned ducted at $9,000 to $12,500 installed, with the smaller singles landing around $8,000 to $11,000 for 12.5kW. A split for a studio or teen retreat is $1,800 to $3,000. Fault-finding is $250 plus GST, fix quoted first. 4.8 stars from 280+ reviews.
The 2000s systems are the story here, same as much of the Hills: good gear that's done 15-plus summers and is starting to cost money. The honest line is the $600 rule - past that on an old system, the money belongs in a modern inverter that will cool the same house for noticeably less power.
Glenhaven's living areas run tall - voids, raked ceilings, double-height entries - and they hold more air than the floor plan suggests. Sizing on square metres alone undercooks these homes. We size on volume and glass, zone the voids sensibly, and the system holds the house without running flat out.
Replacements reuse sound duct runs, which keeps the swap efficient. Size yours properly with the sizing calculator and check the pricing guide before anyone quotes.
Glenhaven sits in the middle of our Hills run with Castle Hill, Dural and Kellyville.
The ducted air conditioning Glenhaven runs on is big and zoned: 14 to 16kW across two storeys, sleeping zones separate from the living core, voids handled properly. Mick has run our Hills installs since 2009 and Glenhaven's executive homes are his standard week. New installs and 2000s replacements both land at $9,000 to $12,500 fixed, with lifetime workmanship warranty and the duct runs reused where they're sound.
Because the Hills has been our installer patch for decades and the work shows it - clean penetrations, balanced airflow, zoning that matches how the family lives, and a fixed quote that doesn't move.
Mick Daly runs the installs and has since 2009. Noah Hall handles the splits. Ben does quotes and diagnostics, and for air conditioning repairs Glenhaven's bigger systems get instrument-led diagnosis rather than parts-swapping guesswork.

Jays Air Jobs Done in Glenhaven
Three recent ones from around the suburb.
The typical Glenhaven 4-5 bedder runs $9,000 to $12,500 for 14 to 16kW zoned. Smaller single-storeys land around $8,000 to $11,000. Replacements reusing sound ducts come in at the friendlier end. Fixed quote first.
Heat rises into the sleeping zones and voids pull cool air down to the living areas. The fix is zoning designed for it – separate upstairs zones with enough airflow allocated. On existing systems it’s often a rebalance, not a replacement.
Zone dampers, sensors and capacitors, yes – those are $150 to $500 fixes. A compressor or major refrigerant failure past 15 years, the money belongs in a new inverter. We quote both ways and tell you straight.
Jay’s Air. Family run since 1991, our own blokes not subbies, fixed pricing, 4.8 stars from 280+ reviews. Licence 273312C, ARCtick AU13058. (02) 9820 4500.
From a 16kW six-zone replacement in a two-storey executive home to a split in the backyard studio, we install, repair and service the lot across Glenhaven and the Hills.
Plan the 2000s system swap before it plans itself. The Hills installed heavily in that decade and the replacements are rolling through now - booking in spring beats competing for January install slots after a failure.
And give the upstairs its own zones with real airflow. Two-storey comfort lives or dies on that one design decision, and it costs little to get right at install time.
