Our coverage in Wealdstone
Premises in Wealdstone are often in mixed-use buildings with shared roofs and tight access, so outdoor unit positions are agreed early.

How we work in Wealdstone
Assess
We work out how many people use each space and the fresh-air rate needed.
Design
Fan, duct and grille sizes are designed for air flow, noise and energy use.
Install
Ductwork and fans are installed and connected to controls. In Wealdstone we agree timings around your opening hours.
Balance
Air flows are measured and balanced to the design.
Local points to consider
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
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.
Noise
Fans and grilles are selected and attenuated to keep noise down.
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 Wealdstone
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.

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).
