The steps for a project in Frome

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.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Before you book in Frome
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.
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.
One outdoor unit, many rooms
Multi-splits save wall space but share a single compressor. For server rooms or critical spaces we recommend dedicated systems.
Working hours
Most Frome businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Who we work with in Frome
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
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.
