How it works in Dartford

  1. Survey

    We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go.

  2. Design and quote

    You get a written specification with unit sizes, positions, pipe routes and a fixed price — plus any planning, landlord or noise points to resolve first.

  3. First fix

    Pipework, cabling and condensate runs go in, usually above ceilings or in neat trunking, before the units are hung. We keep work areas in Dartford screened and tidy at the end of each day.

  4. Install and test

    Indoor and outdoor units are fitted, the system is pressure tested with nitrogen, evacuated and charged with refrigerant.

  5. Commission and hand over

    We set up controls, check air flows and temperatures, show your team how to use it and hand over the F-gas and commissioning paperwork.

Things to check in Dartford

Condensate

Every cooling unit produces water. We route it to a drain by gravity where possible and fit a quiet condensate pump where not.

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.

Planning and noise

Outdoor units on commercial buildings often need planning permission — particularly on a front elevation, in a conservation area or on a listed building — and councils may ask for a noise assessment.

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.

Typical premises in Dartford

  • Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.

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.

It depends on where the outdoor unit goes and the building. Units on a rear flat roof are often straightforward; front elevations, conservation areas and listed buildings usually need consent. We flag this at survey.
