The steps for a project in Northolt
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork. For sites in Northolt we confirm access and parking beforehand.
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.
Test and commission
The condensate pump is water-tested, the system pressure tested and charged, and air directions set.
Local points to consider
Ceiling grid
Compact cassettes drop into a 600 mm grid; full-size units need the grid adapting around a larger panel.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Cleaning access
Filters need cleaning regularly, so cassettes should be reachable with a step ladder.
Working hours
Most Northolt businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Typical premises in Northolt
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
