What this work involves
Discuss occupancy, existing provisions, sound and duct space. Have the system designed and commissioned for the home.
- System choice
- Ducts, terminals and noise
- Maintenance and commissioning
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Bring connection points, controls and maintenance access together on room sheets.
Decide this before construction
Prioritise decisions affecting several rooms before individual product choices. Then use room-by-room decision dates linked to the work that would otherwise wait.
Allow for later maintenance
Organise product and care information by the same room structure. Documentation then remains useful when only one element is replaced later.
Cost factors for this service
Costs depend on system, duct routes, access and finishing. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for ventilation & heat recovery. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging ventilation & heat recovery?
Replacing a ventilation unit may not be enough. Supply air, transfer paths and duct condition also determine overall performance.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
