Points to plan for in Chelmsford

Grease

Units near kitchens need cleaning more often, and sometimes relocating.

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.

Smells

Musty smells usually mean biological growth in the coil or tray; a deep clean and drain treatment normally cures them.

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.

Typical premises in Chelmsford

  • Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
  • Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
  • Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
  • Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.

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.
