Air Conditioning Sydney

MCM Air Conditioning delivers air conditioning installation, repairs and servicing to homes and businesses across Sydney. Whether it is one bedroom that will not cool down or a whole house that needs year-round comfort, the result is a system sized to the space and installed to last.

Based in Prestons, MCM services properties within 50 kilometres, from the south-west growth suburbs to most of the wider city. The work covers split systems, ducted air conditioning, multi head units and reverse cycle heating and cooling, along with the repairs and maintenance that keep running costs down and systems out of trouble.

Every install and repair is fitted to the manufacturer's warranty requirements, so the system performs the way it should for years. Send the quote form with a photo of the space, or call 0487 757 401 to discuss the job.

About MCM Air Conditioning

MCM Air Conditioning is Marco Meli's owner-run business, built on measured quotes, tidy installs and systems that perform as promised. The scope agreed at the quote is the scope delivered on the day, from single bedroom splits to full ducted systems.

The work is split between residential and commercial: houses and apartments on one side, shops and offices on the other. Much of it comes from the new estates around the south-west, where builder-spec homes are commonly handed over without cooling.

Everything is documented: ABN 71 226 676 403, ARC refrigerant handling licence L173546, and itemised quotes that show what the unit, the labour and the extras each cost, including the wall-hung Daikin splits that feature in most recent work.

What We Do

Wall-hung split system head high on a plain wall in a bright modern living room

Wall-hung split systems for single rooms and open living areas, sized to the space rather than the special of the week. Each unit is positioned for airflow, with piping and penetrations sealed and finished cleanly.

One concealed system conditioning every room through ceiling outlets. Zoning is designed around how the house is used, so bedrooms and living areas run separately instead of conditioning empty rooms.

Open-plan home with two wall-hung split heads serving the living area and hallway

One outdoor unit running two or more indoor heads. Suited to townhouses and apartments where balcony space is limited and strata caps the number of condensers on the wall.

Multi Split Systems

Cooling in summer and heating in winter from the same unit, at a fraction of the running cost of plug-in heaters. Most systems MCM installs are reverse cycle, because in Sydney they work all year.

Fault finding for units that will not start, will not cool, trip the power or leak. The fault is diagnosed and the repair quoted before any work begins, so a repair can be weighed against replacement with real numbers.

Homes, apartments, shops, cafes and offices. Commercial work is quoted around trading hours, so installs and repairs happen while the doors are shut rather than in the middle of service.

Areas We Serve

MCM Air Conditioning is based in Prestons and services the whole of Sydney within 50 kilometres, with most days spent in the south-west.

Liverpool 2170

The centre of the region and ten minutes from base. Air conditioning in Liverpool runs from apartment splits near the CBD to full ducted systems in the established streets around it.

Casula 2170

Just across the Hume from home, so Casula jobs often get the first slot of the day. A mix of established brick homes that suit ducted retrofits and townhouses that call for multi splits.

Carnes Hill 2171

Five minutes away, around the shopping precinct. Family homes here run hard on cooling through summer, and an oversized west-facing living room is a familiar quote.

Edmondson Park 2174

A growth suburb of new two-storey builds, many handed over with no cooling at all. Air conditioning in Edmondson Park is mostly first-time ducted installs while the paint is barely dry.

Hoxton Park 2171

Established streets with plenty of ageing units due for replacement. Air conditioning in Hoxton Park is often a straight swap: same wall, new unit, colder air, smaller power bill.

West Hoxton 2171

Larger blocks and larger houses, where a single split rarely keeps up. Multi splits and zoned ducted systems are the usual answer here.

Middleton Grange 2171

A newer estate where builder-spec homes arrive cooling-ready but empty. We run the electrical conversation with the sparky and have the system in before the first heatwave.

Green Valley 2168

Solid brick homes from the 80s and 90s, most with roof space that takes ducted well. Air conditioning in Green Valley splits evenly between new installs and keeping older units alive.

Hinchinbrook 2168

Tucked between Green Valley and Hoxton Park, so we are through it constantly. Repairs and maintenance make up a lot of the work in Hinchinbrook's established homes.

Austral 2179

One of the fastest-moving land releases in the south-west, with new homes finishing every week. First installs into new builds are the standard Austral job.

Moorebank 2170

Across the Georges River, ten minutes on the M5. A mix of older homes due for their first proper system and newer developments wanting zoned ducted.

Leppington 2179

New estates spreading in every direction from the station. Air conditioning in Leppington is dominated by ducted installs into two-storey family homes.

We also cover the rest of the ring around Prestons, including Lurnea, Cecil Hills, Horningsea Park, Denham Court, Glenfield, Warwick Farm and Chipping Norton, and take jobs across the wider city within 50 kilometres.

Frequently Asked Questions

Room size, ceiling height, insulation and which way the windows face all shift the answer, but as a rough guide a standard bedroom needs 2.5kW and an open living area 7kW or more. We measure rather than guess, because an undersized unit runs flat out and an oversized one cycles and never dehumidifies properly.

A back-to-back split system install starts around the low thousands including the unit, and ducted systems run well into five figures depending on home size and zoning. Every quote is itemised so you can see what the unit, the labour and the extras each cost, and there is no charge for quoting.

A straightforward back-to-back install, where the indoor and outdoor units share a wall, is usually done in half a day. Longer pipe runs, double-storey homes or awkward condenser positions can push it to a full day, and we tell you which it is before we book it in.

Once a year for a home that uses it seasonally, and every six months for units running daily or in commercial spaces. The difference shows up in the power bill and the lifespan, and a service visit is where small refrigerant and drainage problems get caught before they become repairs.

Nine times out of ten it is a blocked condensate drain, and the fix is quick. Less often it is a refrigerant issue causing the coil to ice up and thaw, which is worth catching early because it points to a leak that will eventually kill the compressor.
