What size unit should I
purchase? Air conditioners are rated in Kilowatts
(kW). This is a measure of two factors: an air conditioner's output
capacity (the amount of heat that will be removed (cooling) or
added (heating) to the room/s in your house by the air
conditioner); and its energy consumption (the energy the air
conditioner uses per hour at rated capacity). Both these
measurements are shown on the Energy Efficiency Rating label found
on all air conditioners as Capacity Output kW and Power Input
kW.The amount of kW you will need depends on the size of the room
you want to heat/cool and its heat load which is determined by
factors such as the amount of windows and sunlight in the room,
weather conditions and what type of insulation you have. Many air
conditioners list a suggested room size to match the kW rating. You
should consider room size as well as insulation, windows and so on
with the sales member. You may also wish to consider getting an air
conditioning professional to measure your room's heat load and the
required kWs needed to heat/cool it.
What is an
inverter system? An inverter system lets your air conditioner
alter the speed of its compressor in response to heating or cooling
demand. The result is an energy efficient system that is not only
cheaper to run, but also uses a smaller power supply.
What is
the difference between a split system and a multi split
system? A split system has an indoor and outdoor
part that is connected together. Meanwhile a multi split system has
just the one outdoor part that is connected throughout the house
through multiple indoor parts installed in each
room.
Can a home
unit cause Legionella? The majority of cases are caused by
incorrect cooling tower maintenance. Cooling towers are used in
commercial air conditioning to cool water condensers and in
industries to cool recirculated water.
How often
will filters need to be changed? You should inspect the air filters in your
air conditioner regularly. Trapped particles in the filter can
build up and block the airflow. This reduces the air conditioner's
cooling/heating ability .
Should
outdoor units be covered in winter? Outdoor units are designed to withstand
seasonal changes so they do not need to be covered. Heat pump units
operate all year round and if you cover them, it may cause
damage.
What is
the average life expectancy for heating/cooling
units? The average life expectancy of an air
conditioner is about 10 years. When the air conditioner starts
having more problems that are not cost-effective to fix, it may be
time to replace it. |
