From enquiry to handover in Brighton
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 Brighton 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
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
Conservation areas
Historic streets and listed buildings in and around Brighton are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
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.
Working hours
Most Brighton 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 Brighton
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
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.
