How it works in Horsham
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 Horsham 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.
Before you book in Horsham
Void depth
Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure before quoting.
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.
Leased premises
If your Horsham 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.
Typical premises in Horsham
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
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).
