As the cost of home energy consumption continues to soar
along with concerns about greenhouse gas emissions, choosing the right air
conditioner (AC) requires careful consideration of factors aside from cooling
comfort.
Air
conditioners come in various types, each of which has its own advantages and
disadvantages.
Ducted
A ducted AC system
is one that provides cooling to multiple rooms through a series of ducts which
are usually installed in the roof of your home. This is a more complex system
that requires the installation of a professional and is more expensive than
other types of systems.
Evaporative
An evaporative
cooling system works by drawing hot air from the outside and turning it into
cool air inside your home. This is less expensive and more energy efficient
than a ducted AC system and requires only the services of a qualified
contractor for its installation. This works best in areas with low humidity.
Refrigerated
A refrigerated
air conditioner uses the evaporation of a refrigerant liquid to provide
cooling. It is the common choice of many households because it functions well
in very hot weather and lowers humidity inside homes.
Reverse cycle
This is a
2-in-one heating and cooling unit that works well in homes that experience
seasonal hot and cold temperatures as the reverse cycle unit can be used as a
heating and cooling system depending on your needs.
Split type
A split AC
system provides cooling comfort using an indoor and outdoor unit. The split
type is preferred to ducted air conditioners because it is relatively easier to
install. Depending on the size of the room you intend to cool, the split type
unit can also be more energy efficient than a window type air conditioner.
Here are some
factors to consider when choosing the system that is right for you:
Cost
Mobile
evaporative coolers are the least expensive, followed by window installed
types. Split type units may cost more than window and wall types but not as
much as the complex ducted air conditioning system which entails a separate
expense for professional installation.
Energy costs
In Australia,
manufacturers are required to display the Energy Rating Label containing a star
rating for greenhouse gas emissions and useful information about the energy
consumption of an air conditioner. Total energy consumption is expressed in
kilowatts per hour (KWH) while a high star rating means fewer greenhouse gas
emissions. To save on energy bills, look for a unit that shows a low KWH
consumption.
Size
The cooling
capacity which is expressed in kilowatts should be proportionate to the size of
your room. Know your room's measurement to arrive at the appropriate cooling
capacity for your AC.
Other factors
that can affect your choice include noise levels and appliance enhancements
such as the remote control, timer and digital thermostat. Nowadays, choosing
the right air conditioner is fast and convenient as you can compare technical
specifications and features of several models online.
