How we work in Hemel Hempstead
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 Hemel Hempstead 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.
What to think about in Hemel Hempstead
Void depth
Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure before quoting.
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.
Cleaning access
Filters need cleaning regularly, so cassettes should be reachable with a step ladder.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Types of premises we cover in Hemel Hempstead
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- 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.
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).
