From enquiry to handover in Trowbridge
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 Trowbridge 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.
Points to plan for in Trowbridge
Void depth
Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure before quoting.
Conservation areas
Historic streets and listed buildings in and around Trowbridge are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Cleaning access
Filters need cleaning regularly, so cassettes should be reachable with a step ladder.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
