New installs and builder-grade upgrades for Marsden Park's new estates. Since 1991.

Covering Marsden Park and the north-west growth corridor.
New homes, new installs, and a steady stream of builder-grade systems that were never sized for the house.

Marsden Park is new-build country and that shapes everything we do here. Half the work is first installs into homes that came without air con, and the other half is upgrading builder-grade systems that look good on a brochure but can't hold the open plan on a real January day. We know the estate floor plans by heart at this point.

30+ Years

The stock is almost all post-2015: two-storey family homes on compact blocks, big open-plan living, dark roofs, and double glazing that helps until the western sun finds the glass. Plenty came with a basic ducted or a single split from the builder - sized to a budget, not to the house.

About Us

Air Conditioning in Marsden Park

After air conditioning in Marsden Park? Jay's Air has been doing it since 1991. A typical two-storey 4-bedder here wants a 14 to 16kW zoned ducted system at $9,000 to $12,500. A 2.5kW split for one room runs $1,800 to $2,100. Fault-finding is $250 plus GST with the fix quoted first. 4.8 stars from 280+ reviews.

The question we hear most out here: why doesn't my brand-new house cool properly? Because the builder-grade system was priced into the package, not engineered for it. A 10kW unit on a 280-square-metre two-storey with western glass never had a chance. The fix is honest sizing - sometimes zoning changes, sometimes a bigger unit.

Dark roofs and open plans change the numbers

The estate spec of dark roof tiles, high ceilings and open-plan living adds serious heat load. Homes here regularly need a size up from what the floor area alone suggests - 14kW where an older suburb's 4-bedder takes 12.5. Zoning matters double on two storeys so the bedrooms upstairs aren't fighting the living areas downstairs all evening.

If you're building, rough in the air con before handover - pipe runs and circuits cost little during the build and plenty after. Run your plans through the sizing calculator and check the pricing guide before signing anything with the builder.

Marsden Park anchors our north-west run alongside Riverstone, Schofields and Quakers Hill.

Ducted Air Conditioning in Marsden Park

Most of the ducted air conditioning Marsden Park orders from us is either a first install into a home that came without it, or replacing an undersized builder unit that never coped. Mick has run our installs since 2009 and the two-storey estate homes are his daily bread - 14 to 16kW, properly zoned, $9,000 to $12,500 on a fixed quote with lifetime workmanship warranty. We also do air conditioning installation Marsden Park builders rough-in at frame stage.

Why Marsden Park Calls Jay's

Because we size for your house, not for a package price. The estate spec sheet says one thing - the western glass, dark roof and open stairwell say another, and we quote for the second one.

Mick Daly runs the ducted installs and has since 2009. Noah Hall handles the splits and garage conversions. Ben does quotes and diagnostics himself.

Full ducted install in a two-storey 4-bedder

Problem

Two-storey family home delivered with no air con at all - the package upgrade had been cut to hit the build budget, and the first summer made the family regret it.

Diagnosis

Mick fitted a 16kW Panasonic ducted with 6 zones, upstairs and downstairs running independently. Two days, $12,100 fixed, lifetime workmanship warranty.

Builder system that never cooled the living room

Problem

Eighteen-month-old home with a builder-grade 10kW ducted that ran flat out and still lost the open plan every afternoon. Owners thought it was faulty.

Diagnosis

Ben tested it - nothing wrong, just undersized for the western glass. Rezoned the system to prioritise the living areas and resized airflows. $480 of rework bought years of usability before a future upgrade.

Split for a garage home office

Problem

Converted garage office on an estate block, unworkable past 10am in summer with the dark roller door soaking up the sun.

Diagnosis

Noah fitted a 3.5kW Panasonic split sized up for the door heat load. Half a day, $2,300 fixed, and the office works year-round now.

FAQs

Air Conditioning Marsden Park - Common Questions

FAQs

The typical two-storey estate 4-bedder wants 14 to 16kW zoned, which runs $9,000 to $12,500 installed. Single-storey homes land around $8,000 to $11,000 for 12.5kW. Fixed quote off your floor plan or a site visit.

Usually because the builder-grade system was sized to a budget, not the house. Dark roof, open plan and west glass add load the spec ignored. Sometimes rezoning fixes it cheaply, sometimes the unit needs a size up – we test before we recommend.

Yes. Pipe runs, drains and circuits cost little at frame stage and a lot after handover. We do rough-ins for owner-builders and can work in with your builder’s schedule.

Air Conditioning Advice for Marsden Park Homeowners

Check your builder warranty before paying for repairs on a young system. Plenty of builder-installed units carry 5-year parts warranties that owners never knew about. We'll tell you if your fault should be a warranty claim instead of our invoice.

And keep the outdoor unit breathing. The compact estate blocks tuck condensers into side passages where fences trap the hot air - if yours sits in a dead-air corner, it's working harder than it should.
