How we work in Cornwall
Survey and route
We check void depths and plan routes for supply and return ductwork.
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. In Cornwall we agree timings around your opening hours.
Balance and commission
Air flows are measured and balanced, then the system is commissioned.
Things to check in Cornwall
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.
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.
Who we work with in Cornwall
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
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.
Your questions answered
How much does ducted air conditioning cost in Cornwall?
Guide prices in Cornwall run from about £3,595 to £8,250 per ducted zone, plus VAT. A typical job (reception or boardroom with one ducted zone) costs £4,095–£8,250 plus VAT. We fix the price in writing after a free survey.
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.
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.
