Andrew and the teamAussie Services

Penrith Aircon Installers is the air con team at Aussie Services: the Aussie logo you see here, family owned in Sydney since 2009. Andrew started the business and has been a licensed electrician since 2008, which is why the electrical side of every install stays in-house. Our techs and electricians work under the Aussie name you’ll see on their shirts and utes.

Who comes out: a tech from our air con team measures up and quotes on site, and our own electricians do the circuit and any switchboard work. One company, one licence, one fixed price.

Split, ducted and replacement air conditioning for St Clair houses

Almost every home in St Clair is a freestanding house, split close to evenly between three bedrooms and four or more. A three-bedroom place suits splits in the living room and main bedroom, or one multi-split running both. Four bedrooms and an open living area make a strong case for zoned ducted, with the bedrooms on their own zone.

Plenty of St Clair homes are owned outright, and a tired system in a long-held house is a job we know well. On the visit we measure each room and its sun, look over the roof space and the board, and ask whether the old outdoor unit's spot still makes sense. Our electricians run a fresh circuit for the new system, quoted in the same price.

Summer heat and a long-settled 1970s estate

Every St Clair install starts from the heat. Air temperatures here reached 47.3 °C between mid-December 2019 and early January 2020, and the area around Penrith is the hottest part of Western Sydney. A wall unit that coped years ago can struggle on those afternoons, so we size the new system for the hottest day, not the average one.

St Clair stayed rural until the housing estate arrived in the 1970s, taking its name from a 1970 estate, and the suburb kept filling out for years afterwards. Until late 1981 it shared one development area with Erskine Park. That long build-out means homes from several eras sit side by side, so we look at each one fresh: roof space, insulation, switchboard and the window that takes the afternoon sun.

The suburb is framed by Mamre Road to the west, Erskine Park Road to the east and the M4 to the north, with its shopping centre, refurbished in 2008, in the middle. Houses sit next to each other on suburban blocks, so where the outdoor unit goes matters to you and to the people over the fence.

Replacing an older St Clair unit and keeping it neighbour-friendly

Still running the original wall unit? We remove it, reclaim the gas safely, seal the old wall penetration and fit a new inverter system sized for the room as you use it now. If the old outdoor unit sat under a neighbour's window, the replacement is the moment to move it.

Quiet hours apply across NSW. Monday to Friday, your unit mustn't be audible in a neighbour's bedroom or living room until 7 am or from 11 pm; on weekends and public holidays the quiet runs until 8 am and again from 11 pm. Those limits lift while a severe or extreme heatwave warning is current. We place units well away from neighbours' bedrooms either way.

Tips for St Clair homes

  1. Note which neighbour's windows face your old outdoor unit. A replacement is the easy time to move it somewhere quieter for everyone.
  2. If your switchboard still has old ceramic fuses, mention it when you book. Our electricians plan the upgrade into the same visit as the install.
  3. Pick a shaded wall for the outdoor unit, south or east if you have the choice. Out of the western sun, it runs cooler and more efficiently.

St Clair questions

Another question? Call 1300 952 521, or ask it in the quote form.

Which St Clair is this?

St Clair 2759, the Penrith suburb between Mamre Road and Erskine Park Road, south of the M4. Every quote, install and service visit here is handled by our own team, with the electrical work done in-house.

Should I replace my St Clair wall unit with splits or go ducted?

Keep to splits if you cool two or three rooms; go ducted if you want the whole house comfortable. In a four-bedroom St Clair home with an open living area, zoned ducted is the better fit. We price both at the measure-up so you can compare.

What happens to the old system when you replace it?

We recover the refrigerant properly, remove the indoor and outdoor units, and take them away. The old pipe hole is sealed or reused, the new system goes in on its own circuit, and you're left with a tidy wall and nothing to dispose of.

Will a new system cope with St Clair's hottest days?

Yes, because we size it for them. St Clair reached 47.3 °C over the 2019–20 summer, so each room gets capacity for its hottest afternoon, not an average day, and we choose an inverter system that runs efficiently at full load.

What customers say about the air con team

Excellent service. Installed new aircon. They came a week earlier to fit me in. Highly recommend them. And a human being answered the phone when I cold called them. Not like competitors who blabbed on and on with recorded message and then I had to leave my number for a calkback.
