How we work in Darlington
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 Darlington 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 Darlington
Void depth
Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure before quoting.
Access and parking
Town-centre jobs in Darlington 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.
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.

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.

Do I need a suspended ceiling for a cassette?
Yes, or a ceiling void with access. In solid ceilings a wall-mounted or ducted unit is usually the better option.
What size cassette do I need?
It depends on the heat load. As a guide, a compact cassette suits a room of up to about 40–50 m² of office space; larger spaces use bigger units or several cassettes.
