How it works in Dartford
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 Dartford 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 Dartford
Noise
Duct sizes and grille velocities are chosen to keep noise down in quiet rooms.
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.
Return air
Every ducted unit needs a return air path; we design it rather than rely on gaps under doors.
Leased premises
If your Dartford 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.

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.
Is ducted AC quiet?
It can be the quietest option, because the unit is away from the room. Correct duct sizing and attenuation make the difference.
