Points to plan for in Wiltshire
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
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.
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
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.
Who we work with in Wiltshire
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
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.

Why do I need a heat load calculation?
It sizes the system to what the room actually needs, avoiding oversized equipment that wastes money and undersized equipment that cannot cope.
Is the survey free?
For a straightforward installation, the survey and heat load are free with your quote. Full design packages for larger projects are charged and credited if we install.
