How it works in Chesham
Survey and route
We check void depths and plan routes for supply and return ductwork. For sites in Chesham 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.
Before you book in Chesham
Noise
Duct sizes and grille velocities are chosen to keep noise down in quiet rooms.
Leased premises
If your Chesham 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.
Return air
Every ducted unit needs a return air path; we design it rather than rely on gaps under doors.
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.

- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.

Which postcodes do you cover in Chesham?
All of them, including HP5. Give us your postcode when you enquire and we will confirm the visit details.
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.
How much ceiling void is needed?
Low-profile units can work in around 250–300 mm, but the duct route often needs more. We measure at survey.
