How it works in Johnstone
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork.
Set positions
Cassettes are placed against the lighting and grid layout so air reaches the whole space.
Hang and connect
Units are hung on drop rods, connected to pipework and the condensate line. In Johnstone we agree timings around your opening hours.
Test and commission
The condensate pump is water-tested, the system pressure tested and charged, and air directions set.
Things to check in Johnstone
Ceiling grid
Compact cassettes drop into a 600 mm grid; full-size units need the grid adapting around a larger panel.
Working hours
Most Johnstone businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Void depth
Compact cassettes typically need around 250–300 mm of clear void; larger units need more. We measure 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.
Who we work with in Johnstone

In Scotland, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; systems with an effective output of 12 kW or more also need a periodic energy inspection.
