Marayong is older Blacktown - post-war fibro and brick homes on generous blocks, plenty of original owners and long-term families, and air con that gets added a room at a time rather than all at once. We've worked it for decades off the Blacktown run. The jobs are honest: splits installed properly, old gear repaired when it makes sense, replaced when it doesn't.
After air conditioning in Marayong? Jay's Air has been doing it since 1991. A 2.5kW split for a bedroom runs $1,800 to $2,100 installed, a 5kW living room unit $2,500 to $3,000, and whole-house ducted lands at $7,000 to $11,000 where the roofline suits. Fault-finding is $250 plus GST, fix quoted before we start. 4.8 stars from 280+ reviews.
With splits of mixed ages doing the work here, the honest rule matters: under $600 on a unit under 15 years, repair it. The 20-year-old one rattling in the back bedroom? Put the repair money toward its replacement instead.
A typical Marayong home runs a newish living room split and a couple of older bedroom units. When one fades, the answer depends on which one: the five-year-old gets repaired without question, the fifteen-year-old gets the honest maths. We test before we talk, so you're deciding with real numbers - not replacing gear with years left or pouring money into gear without any.
Granny flat or duplex going in? Dedicated splits beat extending anything. Numbers first with the sizing calculator and the pricing guide.
Marayong sits on our Blacktown run with Blacktown, Quakers Hill and Doonside.
The air conditioning repairs Marayong rings about are the staples of hard-working splits: capacitors on hot days ($150 to $180), slow gas leaks showing as fading cooling ($200 to $350 once repaired), blocked drains dripping inside ($120 to $150), and fan motors squealing their notice ($300 to $500). Most done same visit, quoted first, 12 months on parts. Ben does the diagnostics.
Because we fix what's worth fixing and say plainly when it isn't. In a suburb where most homes run several units of different ages, that triage honesty is the whole service.
Mick Daly runs the ducted installs where rooflines suit. Noah Hall does the splits, and split system installation Marayong bedrooms and granny flats order is his regular work here. Ben handles quotes and diagnostics himself.

Jays Air Jobs Done in Marayong
Three recent ones from around the suburb.
A 2.5kW bedroom split is $1,800 to $2,100 installed, a 5kW living room unit $2,500 to $3,000 – mounted properly into the studs on fibro homes, with old holes sealed when we replace existing units.
Under $600 and under 15 years old, repair. Past both, replace. With multiple units of different ages, we test each and give per-unit verdicts – no blanket answers.
Where the roofline suits, yes – $7,000 to $11,000 for 10 to 12.5kW. Plenty of the post-war homes do better with two or three well-placed splits for less money. We tell you which yours is.
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 triaging three mixed-age splits in one visit to a flat install before Christmas, we install, repair and service the lot across Marayong and the Blacktown area.
On fibro, the bracket must hit the studs - sheeting-only mounts pull out and take wall with them. If your existing split wobbles, get it remounted before it becomes a repair bill with a plasterer attached.
Building a flat out back? Rough the split's pipe run in during the build and save the retrofit money.
