How it works in Durham
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 Durham 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 Durham
Ceiling grid
Compact cassettes drop into a 600 mm grid; full-size units need the grid adapting around a larger panel.
Access and parking
Town-centre jobs in Durham 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.
Void depth
Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure before quoting.
Working hours
Most Durham businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Typical premises in Durham
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.

- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
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.

How noisy are ceiling cassettes?
At normal fan speeds modern cassettes are quiet enough for offices and restaurants. We select fan speeds and unit sizes so they are not working flat out.
Can a cassette bring in fresh air?
Many cassettes have a knock-out for a fresh-air duct, so ventilation air can be connected. The ventilation system still needs designing separately.
