The steps for a project in Hemel Hempstead
Survey and route
We check void depths and plan routes for supply and return ductwork. For sites in Hemel Hempstead we confirm access and parking beforehand.
Design the air side
Grille sizes and positions are chosen for even air flow and low noise.
Install unit and ducts
The unit is hung with access for servicing; ductwork and grilles are fitted.
Balance and commission
Air flows are measured and balanced, then the system is commissioned.
Points to plan for in Hemel Hempstead
Noise
Duct sizes and grille velocities are chosen to keep noise down in quiet rooms.
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.
Void depth
Low-profile ducted units can fit voids of around 250 mm, but ductwork adds depth. We measure the route as well as the unit position.
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.
Premises we work in around Hemel Hempstead
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.

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).

Is ducted air conditioning more expensive?
Usually a little more than a cassette of the same capacity, because of the ductwork, grilles and access panel. In return you get a much cleaner ceiling.
Can one ducted unit serve several rooms?
It can, but every room then shares one thermostat. Rooms with different uses are better on separate units or zones.
