The cost of installing split system air conditioning.

Table of Contents

Australia is a country of weather extremes. When the heat is on or the temperature drops, we turn on the air conditioner. With such temperature extremes split system air conditioners are ideal for both cooling and heating a specific area of a home. So, you may ask, what is a split system air conditioner and how much is it going to cost me? Well, let’s find out.

What is a split system air conditioner?

As the name suggests, this is an air conditioning system that is split into two parts–an indoor unit which is either freestanding (but still attached to the lower part of the wall) or hung on the wall, near the ceiling in the room you want to temperature control, and a condenser, which is installed outside the house. Both units are connected through insulated copper piping and electrical cables which run through the wall, to ensure the aesthetics of the room are not spoilt.

Types of split system air conditioners

As we’ve mentioned, each home has its unique requirements and therefore it is important that you also know the different types of systems available as these work on the same principle but are suitable for different homes and heating/cooling needs. In turn, affecting the price you pay.

  • Reverse cycle split system: used to cool your home on hot summer days and heat your home in winter.
  • Inverter system: makes sure the air conditioner’s compressor is at an appropriate speed to maintain the desired temperature. In turn, being more energy-efficient and saving you money on your bills. These days most systems have inverters.
  • Multisplit system: unlike a regular split system which has one indoor unit and one outdoor unit, a multi-split system has one large outdoor unit that is connected to two or more indoor units. Allowing you to heat/cool multiple rooms at the same time. In this case, extra piping is required and therefore, it is recommended that the outdoor unit be located as centrally as possible.

So, now that you have a gist of what a split system air conditioner is and how it works, let’s take a closer look at the factors that will affect the pricing.

  • The air conditioning unit you have chosen: Different brands of split system air conditioner differ slightly from one another, but the installation process is the same. However, the price will vary depending on the size of the unit and the type of system.
  • How many units you are installing: Such installations incur extra costs in terms of material and labour. For instance, the more units you install, the more time it will take, in which case increasing the price.
  • Ease of access and installation on your property: Every house has its unique layout and is designed differently. Bearing this in mind, access to the roof and tight spaces may create more work and impact the installation costs.
  • Additional services: In some cases, upgrading of the switchboard may be necessary or it may require electrical tasks for which you will need to hire an electrician. The extra labour and components will lead to more costs.

As mentioned earlier, the cost of installation will depend on several factors and a true quote can only be provided once we carry out an onsite assessment and we know the size of the split system we are working with.

Getting the right price

If you are seeking quotes for split system air conditioning systems, we will work with you to tailor a solution that suits you and your home, while providing you with an accurate quote.

Before you go ahead and make any purchases and commitments, there are a few things we suggest you consider:

  • What type of air conditioning system is right for me and my home?
    Depending on the size and layout of your home, a split system air conditioner unit may not necessarily be the most appropriate, you may instead require a ducted system.
  • What size air conditioner do I need?
    To determine what capacity air conditioner you need, you will need to consider:
    The size of your home: larger homes require larger capacity units. If you own a multi-storey home, then you may require units in different areas, adding to the cost.
    The ceiling height: a home with high ceilings requires a unit with a larger capacity system due to the larger volume of air.
  • How much does an air conditioning unit cost?
    You will want to remain within your budget but at the same time consider the quality, energy efficiency, long-term costs and longevity of the system. All of which will affect the price you pay.
  • What factors will affect the quote?
    As mentioned earlier, several factors will influence your final quote. Other influencing factors include:
    – the amount of refrigeration piping and interconnecting cable used,
    – amount of trunking required,
    – switchboard upgrade (if required).

Key things to remember before you purchase and pay

So, you think you have found the perfect split system air conditioner and decided on finalising a quote. Before you go ahead and finalise a quote and make payments, here is some advice to consider:

  • Ensure you have two to three quotes for comparison so that you can get a sense of what the current market rates are.
  • Always choose a reputable installer who is correctly licensed.
  • Ensure you get the quote in writing. If they cannot provide this, then don’t bother.
  • Most importantly, the air conditioning industry is guided by regulations placed by the Department of Fair Trading. This allows contractors to charge a maximum deposit of 10%. If a contractor asks for higher deposits, refer them to the department’s rules.
    At Peninsula Air Conditioning we strongly abide by these guidelines and you will only receive a final bill once we complete the installation, this is usually a day or two after.
