Do you need to hire a professional to install an air conditioner in Sydney?

Even the most skilled home and business owners are not permitted to install their air cons. The exception is a portable unit, which needs only unboxing and plugging into a nearby outlet. Of course, these are also the least effective at cooling spaces of any notable size.

Only a certified and licensed air con professional can install the following types of air conditioners:

These regulations are in place to keep everyone and everything safe. Air conditioning installation needs electrical work and wiring. Some units also run off of natural gas, which requires work from a certified gas fitter. Larger ducted systems entail a lot of metal work, as well as routing, venting, and proper supports.

How to choose the right air con size to install

A professional installer can help you calculate this based on a set of common factors. It’s important to have the right size air con for the space to avoid the unit straining to achieve the desired temperatures. This can cause spikes in your energy bills and general discomfort when your rooms are not as cool as you’d like. Some of the factors that can impact the size you’ll need to include:

  • Space size
  • Room insulation quality
  • Wall composition
  • Window quantity and type

To get the best efficiency, you must install an air con with the proper power for the size of your room. A very large room will not be cooled using a device that has too few kilowatts of power. But, an appliance with too many kilowatts will waste power in the small room.

Generally, you will need 0.12 to 0.15 kW of power per m². To calculate this, multiply the length of the room by the width of the room. The result will be the square meters for that area. Here’s a sizing guide for you:

Room Size Typical Room Type System Size
10-25 m2 Bedroom | Study | Small lounge |

Small kitchen | Small office

2.6 kW
25-35 m2 Mid-size Bedrooms | Bedrooms with ensuites |

Mid-size lounges | Mid-sized kitchens |

Small rooms with high ceilings | Offices

3.5 kW
45-60 m2 Large bedroom | Bedroom with ensuites |

Mid-size lounges | Large kitchens |

Mid-sized rooms with high ceilings | Offices

5 – 6 kW
60-80 m2 Large lounges | Large open plan areas |

Small shops | Offices

7 – 8 kW

Where is the best place for air conditioning installation?

Where the actual air con unit (or units) are installed will be a factor of their type. Ducted systems will have the unit placed outside by a professional installer, with good access to electrical. Ductwork is then routed to the rooms you specify. Though in most ducted systems, all rooms are included to allow for proper temp control.

Places that are under shade and well ventilated are preffered to prevent heat transfer as well as the unit running less efficiently. For split systems, the outdoor unit is installed close to the indoor unit to maximise efficiency. Most brands allow installation up to 20m apart without the need for extra refrigerant. But, we recommend keeping this distance within 5m if possible.

How much do installers charge in Sydney?

The rate of air con installers will depend on the particularities of your home or office, the type of air conditioner and the number of units you want. For example, an old terrace home in Newtown may offer a more complex install than a standalone property in Glebe.

In Sydney, professional installers charge an average of $90 to $120 per hour for installation.

Frequently Asked Questions About Air Conditioning Installation In Sydney

What do I need to know about air con maintenance?

After installation, we recommend you get a maintenance service every 6 to 12 months. This depends on how much you use the air con and the quality of air in your neighbourhood. This ensures that the unit will work optimaly with clean filters and without any blockages. If you don’t maintain your AC in regular intervals, you will experience a drop in performance.

What are the factors that increase the cost of installing an air conditioner?

Be sure to request a quote for your exact needs:

  • System brand and model
  • System size
  • Installation site access
  • Meter board upgrades
  • Ductwork length
  • Interconnecting cable length
  • Refrigeration piping
  • Existing system removal

What is the best place to install a split system in a house?

In the bedrooms, each split should be located in a place where the air does not flow directly over beds. Throughout the rest of a home, it is recommended that each unit be placed in the centre of each room to provide fair airflow.

What is a back-to-back air conditioning installation?

It is a way of installing wall-mounted split systems where the distance between the indoor and outdoor units is the smallest possible. This is achieved by installing them on the same wall, back to back, with one outside and one inside and only separated by the wall itself. Since the appliances are close together, less equipment is used than in other installations, making this one the cheapest there is.

Another way to save costs when installing an AC is the so-called side-to-back installation. Here, the indoor unit is installed in the upper corner of the room. The outside compressor is placed at ground level and perpendicular to the indoor unit. Both installation types allow the water produced by the internal unit to flow toward the external unit so that the latter expels it.

How long does it take to install a split AC system?

This will vary depending on the type of system you are having installed. Split systems can be fairly straightforward to get in place. If the installation takes place in an area where no other air conditioner has been placed, setting up the new unit may take 4-8 hours. Removing existing units and older wiring can add time to the project, in some cases extending the entire installation to a full day.

In contrast, a ducted system will take a bit more time. Installing the ductwork itself can take one to two days. It will be even longer if the existing ductwork has to be repaired or completely removed and replaced. The air con unit itself will also need several hours for installation including placement, proper wiring, and testing.
