How we work in Chelmsford
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. We keep work areas in Chelmsford screened and tidy at the end of each day.
Balance and commission
Air flows are measured and balanced, then the system is commissioned.
What to think about in Chelmsford
Noise
Duct sizes and grille velocities are chosen to keep noise down in quiet rooms.
Leased premises
If your Chelmsford 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.
Access
Filters and the unit need access for servicing — an access panel is non-negotiable.
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.
Who we work with in Chelmsford
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.

- 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.
