From enquiry to handover in Harrow
Survey and route
We check void depths and plan routes for supply and return ductwork. For sites in Harrow 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.
Local points to consider
Noise
Duct sizes and grille velocities are chosen to keep noise down in quiet rooms.
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.
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.
Leased premises
If your Harrow 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.

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
