  • Size of your roof space. This is important for ducted air-con as the unit sits in your roof cavity and so needs a large area in which to be installed
  • Your Budget for installation and running costs. It is important to consider not just the unit cost and installation but also what you are able to pay for ongoing running costs and servicing when required for air conditioning installation Bundaberg

So what types of air conditioning units / system best suits you

Let's have a look now at the various types of units available

  • Ducted air conditioning systems
  • Split system air conditioning
  • Multi-split system
  • Portable air conditioners
  • Zone controlling air conditioning
  • Smart Air Conditioning
  • Floor mounted air conditioning
  • Window mounted air conditioners

Ducted Air Conditioning or central systems

A ducted system has a central fan coil mounted in your roof space with ducts leading from it to your various rooms.

The advantage of this is that the system is therefore concealed from view other than a vent in each room usually in the ceiling. The result being the system is almost hidden and so is much more aesthetically appealing and far less invasive from that viewpoint.

Additionally

  • the unit allows for zone control in each individual room allowing each room's occupant to adjust the cooling to their liking
  • As there is only one unit efficiency is improved rather than having multiple units, one for each room.
  • Noise is also cut down significantly as the central unit is usually out of hearing.
  • Can be fitted with SMART technology allowing you to remotely access controls via your mobile phone using WiFi technology

Disadvantages to the system are

  • The initial cost of setup can be quite high
  • A large space is needed for the central fan coil unit to fit in the roof cavity
  • The unit is not energy efficient if only used for an individual room
  • The unit is definitely not a DIY due to the complexity of the installation
  • The system suits larger houses with numerous rooms or multiple units
  • There is a small amount of loss of cooling through the ducting material
  • Usually very difficult to fit to existing and older buildings or houses

Split Systems

A split system as the name implies has an indoor fan coil unit usually mounted on the wall of the room to be cooled or heated and an outside condenser unit with the two linked by pipes and wiring conduits. Some internal fan coil units can be floor mounted if desired which makes cleaning the filters more easily accessible

  • Suits most residential and smaller commercial applications
  • Usually, only a small space is needed for the units
  • The units are aesthetically appealing and generally inobtrusive
  • Can be fitted with SMART technology allowing you to remotely access controls via your mobile phone using WiFi technology

Disadvantages are

  • The cooling or heating is only effective in the room in which the internal fan coil unit is installed
  • There is a visible unit in each room of the installation
  • Some find the internal unit unappealing
  • The external compressor unit can be a little noisy and in some cases noisy for your neighbours

Multi-Split Systems

As the name implies multiple internal fan coil units operate with usually one large external compressor unit thus cutting down on the need for numerous external units around the building.

Advantages are

  • High energy efficiency and in fact the most efficient system available to date
  • Multi-room availability from the one external unit
  • The flexibility of having additional units installed if needed, as long as the external unit has the capacity to handle the increased load
  • The external unit can be up to 15 metres away from an internal fan coil unit without loss of cooling efficiency
  • There are cost efficiencies at installation due to only one large external unit being fitted
  • Cost efficiencies for repair, maintenance, servicing and replacement
  • Can be fitted with SMART technology allowing you to remotely access controls via your mobile phone via WiFi technology

Disadvantages are

  • If there are problems with the external compressor unit it will affect all internal units
  • The external unit can only cool or heat so its mode dictates the mode of all internal units

Advantages are

  • Mobility can be moved from room to room
  • The unit is very affordable initially and is a DIY job usually
  • The applications suit rentals particularly as they can be removed easily and don’t breach rental agreements
