How we work in County Londonderry

  1. Survey and route

  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. In County Londonderry we agree timings around your opening hours.

  4. Balance and commission

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

Before you book in County Londonderry

Access

Filters and the unit need access for servicing — an access panel is non-negotiable.

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.

Return air

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

Shared buildings

In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.

Premises we work in around County Londonderry

Compliance in Northern Ireland: refrigerant work falls under EU F-gas rules that apply in Northern Ireland, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).

How much ceiling void is needed?

Low-profile units can work in around 250–300 mm, but the duct route often needs more. We measure at survey.

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.
