How a job in Stevenage works

  1. Survey and route

    We check void depths and plan routes for supply and return ductwork. For sites in Stevenage we confirm access and parking beforehand.

  2. Design the air side

    Grille sizes and positions are chosen for even air flow and low noise.

  3. Install unit and ducts

    The unit is hung with access for servicing; ductwork and grilles are fitted.

  4. Balance and commission

    Air flows are measured and balanced, then the system is commissioned.

Things to check in Stevenage

Return air

Every ducted unit needs a return air path; we design it rather than rely on gaps under doors.

Access and parking

Town-centre jobs in Stevenage often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.

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.

Premises we work in around Stevenage

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).
