The steps for a project in Hounslow
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork.
Set positions
Cassettes are placed against the lighting and grid layout so air reaches the whole space.
Hang and connect
Units are hung on drop rods, connected to pipework and the condensate line. In Hounslow we agree timings around your opening hours.
Test and commission
The condensate pump is water-tested, the system pressure tested and charged, and air directions set.
Things to check in Hounslow
Cleaning access
Filters need cleaning regularly, so cassettes should be reachable with a step ladder.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Ceiling grid
Compact cassettes drop into a 600 mm grid; full-size units need the grid adapting around a larger panel.
Leased premises
If your Hounslow premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
