From enquiry to handover in Grantham
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 Grantham we agree timings around your opening hours.
Balance and commission
Air flows are measured and balanced, then the system is commissioned.
Before you book in Grantham
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.
Noise
Duct sizes and grille velocities are chosen to keep noise down in quiet rooms.
Leased premises
If your Grantham 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.
Who we work with in Grantham
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
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).

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.
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.
