Plans & system selection
Choose the system around the proposed rooms.
Start with the current plans, the rooms to be conditioned and how the owner or occupants intend to use them. A split system for an individual space and a ducted system serving several rooms require different installation decisions. Floor area is useful, but glazing, orientation, ceiling height, insulation and room use also influence the selection. If equipment has already been specified, include the models and controls so the installation can be checked against the building rather than treating the equipment schedule as the complete scope.
- Current drawing revision, site suburb and construction stage
- Rooms to be served and equipment already selected or still open
- Indoor and outdoor locations, available space and access constraints
- For ducted systems, outlets, return air, zones and intended controller operation
