How we work in Barnet

  1. Check the void

    We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork. For sites in Barnet we confirm access and parking beforehand.

  2. Set positions

    Cassettes are placed against the lighting and grid layout so air reaches the whole space.

  3. Hang and connect

    Units are hung on drop rods, connected to pipework and the condensate line.

  4. Test and commission

    The condensate pump is water-tested, the system pressure tested and charged, and air directions set.

Before you book in Barnet

Ceiling grid

Compact cassettes drop into a 600 mm grid; full-size units need the grid adapting around a larger panel.

Conservation areas

Historic streets and listed buildings in and around Barnet 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.

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.

Typical premises in Barnet

  • Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
  • Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
  • Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
  • Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.

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).

Do I need a suspended ceiling for a cassette?

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.
