The steps for a project in Sunbury-on-Thames
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 Sunbury-on-Thames 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.
What to think about in Sunbury-on-Thames
Condensate
Most cassettes include a pump. The discharge still needs a route to a drain, which we design at survey.
Access and parking
Town-centre jobs in Sunbury-on-Thames often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Cleaning access
Filters need cleaning regularly, so cassettes should be reachable with a step ladder.
Leased premises
If your Sunbury-on-Thames 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.
