When considering what air con system is right for them, many people choose ducted air conditioning. This is because it allows them to cool the whole house, with vents in every room that can be switched on or off at will. So they can reduce the cost of running if needed, by closing vents in the bedrooms during the day. And if they have it on throughout the night hours, they can close off the living room and kitchen vents.
While this type of air conditioning is not the most efficient, it is still popular. Why isn’t it considered efficient? That’s because cool or hot air is lost during the transfer from the head to the vents – that is, through the ductwork. This can be mitigated to some extent by using ducting that is made from material that is insulated. This may cost more initially, but it will on running costs over the years and be more eco friendly.
