From enquiry to handover in Wiltshire
Survey
We size the unit to the room and agree indoor and outdoor positions and the pipe route.
Mount the units
Indoor unit on a mounting plate, outdoor unit on brackets or a frame with anti-vibration mounts.
Pipe and wire
Pipework, interconnecting cable and condensate are run and made off neatly. In Wiltshire we agree timings around your opening hours.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Local points to consider
Pipe routes
Shorter, simpler pipe routes are cheaper and more reliable. We plan routes before quoting.
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.
Refrigerant rules
Since 1 January 2025, new single split systems holding under 3 kg of refrigerant in Great Britain cannot use refrigerant with a GWP of 750 or more — in practice, R32 or lower.
Access and parking
Town-centre jobs in Wiltshire 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.
Premises we work in around Wiltshire
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- 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.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
