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.
