Browse Forums Heating, Cooling & Insulation 1 Jan 02, 2012 10:21 pm I know about zones and that you can make say, 2-3-4 zones in a house to control which vents are enabled - but is it possible to get a system where you can make each vent a zone? So for example, there's 30-odd vents in the house, and there's a control panel (or an iPad/computer app) where I can just open/close any vents I like.

As you close off zones you can have problems with oversupply of air of the remaining zones. Systems like Actron and Advantage Air vary the fan speed to compensate but a minimum speed is required to ensure that air still goes through the ducts (and this is further complicated by the varying length of ducts to the rooms). Commercial systems found in offices and hotels treat each space individually with a self-contained return/supply ducting system either using a central supply of chilled water or a water cooling system to take away the waste heat from a local refrigeration system. As Wokwon said, expensive. Paul How do you remove one of these ceiling air con vents? And is it possible to disconnect the duct joined to the vent from inside the house, without going into the roof cavity? 0 5929 Anybody know any good and reasonably priced Air conditioning contractors/companies that could install a ducted air conditioning system in the Central Coast NSW for a small… 0 8992 To my understanding early saw cuts are to control shrinkage cracks, so doing them now would be pointless.
