The steps for a project in Blackheath
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. We keep work areas in Blackheath screened and tidy at the end of each day.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Points to plan for in Blackheath
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 Blackheath businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
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.
Typical premises in Blackheath
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- 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.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
