DP HEATING & COOLING With ducted setups, there are a few common needs people have. The first is installation, especially for new builds, renovations, or homes that are ready to move on from an older system. The second is servicing and repairs, because like any mechanical system, ducted air needs maintenance to keep it running efficiently. And the third is choosing the right type of ducted unit in the first place, like reverse cycle systems that can heat and cool from the same unit, which is a strong option for year-round comfort.
