A Quick Guide to Installing a Split System Air Conditioner

Homeowners across Australia might think about installing a split-system air conditioner when the temperature drops or the heat is on. As a country of extreme weather conditions, it seems that the temperature is getting worse for every Australian. In 2020, a report from the Bureau of Meteorology showed that the country’s climate has warmed on average by 1.4 degrees Celsius.

This has led to an increase in the frequency of extreme heat events, which explains why almost three-quarters of Australian homes have some form of air conditioning. Understandably, air conditioning can be expensive, but split system air conditioners prove to be energy-efficient and pocket-friendly. In today’s post, we’ll look at reverse cycle split system air conditioning, how much it would cost, and what factors need to be considered for installation.

Split Air Conditioners: What Are They and How Do They Work?

These ACs consist of two main parts: an inside air outlet unit and a compressor located outside. They don’t require a series of ductwork networks throughout the ceiling. Instead, they rely on a set of pipes connecting the outdoor compressor to the inside air unit.

This is why they are often referred to as ductless air conditioners. To generate heated or cold air, their refrigerant is dispersed through the copper sides that cycle through the system. What’s good about split system air conditioners is that they have a high energy efficiency rating (as can be seen on their Zoned Energy Rating Label or ZERL), helping you lower your monthly power bill by using less energy.

Factors to Consider When Installing Split Air Conditioners

Whether you’re a residential or commercial property owner looking to install split system air conditioning, you need to tick the following factors off your list before installing an AC system:

1. Location of indoor and outdoor units

   Before the technicians arrive at your property, you have to decide where to put your indoor and outdoor units. Ideally, the inside air outlet unit should be located where the air can be distributed thoroughly without any distractions. You want it wall-mounted at least 8-10 feet from the floor so that it can generate and distribute air thoroughly and still be accessible enough for easy cleaning and maintenance.

   If you’re installing the air conditioner in your bedroom, it should be mounted above the bed so you can enjoy the maximum cooling effect it gives off. For air conditioners going above the window, they should be symmetrical to that window. You want to make the AC look cohesive with the rest of the space, so symmetry is the key here.

   As for the outdoor compressor unit, you want it installed in an open space like the terrace. This is for the air to flow freely over the compressor and condenser. If not practically possible, you can have it mounted on an external wall that’s sturdy enough to hold it firmly and still facilitate proper airflow.

2. Wall strength

   Another thing to consider is the strength of the wall where the unit will be mounted. The wall should be strong enough to hold the unit, otherwise, the unit will crash. To avoid accidents, split air conditioners should not be installed on uneven or false walls. This will also save you from paying additional installation costs.

   While you know your wall more than technicians do, they know how to install reverse cycle split system air conditioners to the highest standard possible.

3. Distance between indoor and outdoor units

   Also, take note of the proper distance between the indoor unit and compressor unit. To maximise the cooling capabilities of your split system, it’s advisable to keep the distance between the outside compressor and the indoor unit as close as possible. They should not be separated by more than 15 metres. This is to facilitate faster flow of the unit’s coolant.

4. Space between the AC and the wall

   Be cautious about the space between the AC and the wall. There should be 15 centimetres surrounding the top and sides of the inside unit, and the same goes for the outdoor compressor unit.

The Cost of Installing Split System ACs

On average, the cost of split system air conditioner installations in Australia varies. Some companies will install a split system you have purchased and only charge for installation. Other companies will supply and install the unit, so they know where the product came from and also customers a piece of mind if there was a manufacturing fault with the system being installed, the installing company will look after organizing warranty repairs.

How much the ac system will cost depends on what size system you need. They range from 2.5kw for a small room such as a study to 9kw for a large open plan area. And also what brand and features you want. Some features such as WIFI control are extra.

In determining how much the install will cost, several factors have a say in the final figure. The type and size of the unit being installed; the ducting, piping, and cabling required; the site of installation; the electrical infrastructure of the property in which the unit will be installed; all these factors are considered when calculating the installation cost. Before making any decisions, it’s a good idea to collect a few quotes from many different contractors.

Bear in mind that only licensed and qualified professionals are permitted to install split system air conditioners. Tradies, such as plumbers, gas fitters, and electricians, could perform the installation but need to be licensed to handle refrigerants as well as having regular qualifications to do the work. If they’re not licensed, you should consider looking for another contractor.
