Ducted air conditioners are the most convenient way of heating and cooling an entire house. One switch controls the entire climate of the house, and it does not even need multiple units to do it. The ducted conditioner sometimes called the octopus or the spider. Depending on the design of the house, the ducted system can go up, down, and sideways to reach every nook and cranny.
Energy Questions One of the biggest concerns that consumers have with this system is that it uses too much energy. But, people looking to invest in a ducted air conditioning system should not worry too much. The best brands in the world design and improve ducted air conditioning systems, to make the systems better and more energy efficient. In fact, ducted systems are more energy efficient than their split system counterparts because they cover a greater space to better effect. Air conditioning works by cooling or heating a room until it reaches the preferred temperature. The lower the temperature required the more power the system uses to reach it. Larger areas take longer to cool if there is just one source. But, multiple sources can do so with the same amount of power, faster. Ducted systems cool the house from different areas, making it easier for the system to reach the favoured temperature, even if air is not contained.
Zoned Out Another concern people have with ducted air conditioning lies with its uniform design. People like convenience, and sometimes that means being able to cool a room without affecting the rest. This is a reasonable request that looks as if it is outside the systems design to fulfil. Fortunately, engineers found a way to make this possible. Zoning is the incorporation of zone motors to the duct designs that allow people to manipulate which rooms get cool, and which rooms do not. This adds another dimension to the system’s energy efficiency. Choosing a system is not a trade-off between the benefits of a ducted or a split system. The former can do all of the things according to its design, while incorporating some of the benefits of the latter for a better performance.
