SPLIT SYSTEM INSTALLATION GUIDE
Split Systems can be installed in a few different ways depending on the layout of your home. They are extremely versatile and easy to install on the ground, on the wall or even on the roof. This page will go through some of the installation types to give you an idea of what options are available.
Back to Back Installation
you have probably come across this term “back to back installation” a few times by now, so what exactly does it mean? as we have explained earlier a split system is made up of 2 separate parts, an indoor unit and an outdoor unit. the term “back to back installation” simply means that wherever you decide to have the indoor unit installed, the outdoor unit gets installed directly behind it on the ground on outside of the wall (see pictures). All split systems installed on the ground must be mounted on a concrete slab and special feet to keep them slightly elevated and fixed in position. This is the easiest and most cost effective way to install a split system air conditioner as there is minimal work required and there is minimal use of electrical cables and copper refrigeration pipes.
Wall Mounted Installation
In some situations it can be beneficial to have your split system mounted on a wall bracket to keep it up of the ground.
Available in 100kg or 200kg maximum weight capacity, wall brackets are a great option if you don’t want to have your split system condensor unit installed on the ground. perhaps your outdoor surface is uneven or prone to flooding. Or perhaps you don't have a whole lot of outdoor space and a condensor unit of the ground would block your walking path.
For most applications, the 100kg wall bracket option is more than sufficient. Wall brackets also come in both powder coating or stainless steel options to make sure they dont rust and maintain their strength. they also use rubber mounting pads to stop the vibrations from travelling through your wall. all in all wall brackets a great alternative option to an installation on the ground
Roof Mounted Installation
Another installation option is to have your split system condensor unit installed on the roof. this type of installation is usually only used when a ground or wall mount installation is available. roof mounts are quite common in townhouses because the houses are so close together or even sometime sharing the same external walls that a split system simply will not fit in between them leaving only the option of a roof mount.
roof mounts can be quite different depending on if you have a pitched or flat roof. Flat roofs are generally easier to work with, pitched roofs can be more challenging and require a specially designed roof mount that attached to the truses (timber) inside the roof to secure it and uses rubber pads to stop any vibration passing into the roof itself. This roof mount is also adjustable to suit the pitch of each roof.
There is also the question of how to get your split system up onto the roof for the installation! if your house is single story then this will be quite simple. but if your house is double story and you have a large heavy unit to install then a hydroponic lifter can be used
Double Story Installation
if you have a double story house you've most likely experienced the intense heat that can build up in bedrooms upstairs during summer making sleeping almost impossible. Because hot air rises the second story ends up with most of the heat from the day trapped inside. This is the reason 50% of our installations are for double story homes.
Installing a split system into a second story comes with many variable installation options (mainly where to mount the outdoor unit) and costs. some double story installation will be the same as a "back to back" with a ground mounted condenser. the only difference being extra distance the pipes and capping have to travel up the wall between the indoor and outdoor unit. (see photo 1)
Special care must be taken when preforming a second story installation as working at heights using an extension ladder is required to make penetrations in the brickwork. in some instances if there are obstacles in the way, such as the eaves of the first level roof blow, a wall bracket may be required (see photo 2)
Apartments come in all shapes and sizes. there are small apartment buildings 5-10 apartments, there are older style apartments building that were built anywhere between the 60s to the 90s, and there are high rise apartment buildings with over 100 apartments. Split system installation in your apartment will usually require a bit more thought and pre-planning.
first thing to think about for your apartment installation is getting body corporate approval. this can mean making a small plan of where the split system will be installed and sending it to your body corporate to approve.
most apartment installation will use a balcony for the outdoor unit as there is no other outdoor space. in most instances the unit can be tucked away in the corner of the balcony or mounted on a wall bracket to save balcony space. first option is to use whats called a"side back to back installation" this mean that the indoor unit is mounted with the side budded up against an external wall, the piping and cabling can then exit through the side of the indoor unit making its way outside to the outdoor unit (see photo 1). If a "side back to back installation" is not possible, due to the fact that most apartments have no roof space or internal walls to run piping, internal capping may need to be used (see photo 2)
Replacing an Old Split System
Do you have an old clunky split system that is struggling to keep your room even remotely cool? these are a thing of the past and it might be time for an upgrade. an old split system air conditioner is noise ugly and inefficient, it is most likely running your electricity bill through the roof every time you turn it on.
the latest Split systems air conditioners have come along way. they are loaded with great features, cutting edge technological upgrades and they also look sleek and stylish hanging on your wall. all the best split systems now use an inverter system which significantly increases the systems lifespan while at the same time keeping running costs at an all time low. New split systems are also equipped with powerful filter that keep your home dust and allergy free.
Your old split system must be removed by a professional ensuring that the refrigerant gas is disposed of correctly as it is quite harmful to release into the atmosphere. we also offer an addition service of taking your split system to be disposed of at a metal scrap yard. once the old unit has been removed the new unit can be installed in the same location using the previous penetrations made.
if you have an old box air conditioner in most instances a split system can be installed above it, and it can be removed at a later date.
Medium to large sized split systems require a new direct electrical circuit with circuit breaker protection to be installed from the switchboard as they tend to draw a fair amount of power to run the compressor, for some old homes and apartments with old switchboards this can pose a problem.
although some old switchboards can be slightly altered to allow for this new power circuit to be installed, we recommend getting your switchboard upgraded to improve the safety of your home and family. to kill two birds with one stone we can arrange your switchboard upgrade and split system installation to be completed on the same day by our team.
Old Fuse switchboards (Photo 1) use old style ceramic style fuses, which are a thing of the past. These types of old switchboard offer little or no protection from electrocution and short circuiting which can cause fires. A switchboard upgrade will mean installing Electrical safety switches and circuit breakers bringing your home up to the new electrical safety standards
