Split systems are among the most preferred types of air conditioning. They are specifically popular around Australia and consumers are always on the lookout for a quality split aircon to keep cool during extremely hot summers. Split systems, as well as reverse cycle split systems, are typically quiet, compact and efficient to run.
While split systems are commonly used in Australian homes, it is still best to know more about this type of air conditioning and what it does before paying for anything significant.
We’ll help you with your buying decisions in this blog. We’ve put together some of the most important things to know when choosing a split air conditioning system for your home or office installations.
What is a Split System?
A split air conditioning system comes in two parts: there’s the outdoor unit and the indoor unit. The outdoor unit is composed of a compressor and a condenser unit, while the indoor unit contains the evaporator. The indoor unit is in charge of blowing cool air inside the property and the outdoor unit dissipates hot air from inside.
Reverse cycle split systems also have condensers but they are placed inside the indoor unit. The outdoor and indoor units of this type of split system are connected via insulated tubes that are piped through a hole in the wall.
Basic features to consider
- Filters and dehumidifier – Several split system units already come with dust and allergen filters which help improve indoor air quality. Consider this feature if there are people within the property who are suffering from asthma. There are also air conditioners that come with dehumidifying technology, which are perfect for properties located in tropical places.
- Air conditioning with heat pump – Some air conditioners are a combination of cooling and heating system. It functions as both air conditioner and heater when in reverse mode.
- Timers – Most split type models are built with timers that let you efficiently control indoor temperatures. The sleep mode feature lets the unit shut off automatically after about an hour so homeowners can fall asleep and save energy at the same time. Some models also let users set the system to their desired temperature in time for their return to the property.
- Remote control – Split systems allow the convenience of having a handy remote users can use to turn their air conditioners on and off without having to get up and reach for it.
- Odour removal – ACs with air purifying feature typically come with the odour removing function. Consider this feature if there are unpleasant smells in the office (e.g. cigarette smoke) or to remove pet odours and the smell of mildew in residential homes.
The right size
In choosing a split system for any property, the starting point is typically size. You will need a split air conditioning system with around 1 to 1.5 kW of cooling capacity for every 10 sqm of space.
Other factors to consider
Here are other factors that have an effect on your AC’s performance:
- Ceiling height
- Level of insulation
- Location and size of windows
- Outdoor space limits
- Number of people occupying the property
- Climate (this should tell whether or not a reverse cycle with heating and cooling capacity is the best option)
Check the energy star rating of the model you are planning to purchase. Energy Star-rated models are proven to significantly contribute to air conditioning energy savings while providing excellent cooling (and/or heating) performance.
Purchase and running cost
Good quality split systems today could cost between $900 and $3,000. There are also running costs involved and these costs quickly add up over time. This is why having an energy-efficient model is important.
