A school in Harrow asked us to survey their server room after the IT manager noticed the AC unit was running 24/7 but the room temperature was still hitting 28°C in the afternoon. The unit was a 3.5kW wall mount installed when the room had four servers. They now had twelve. We calculated the actual heat load, installed a 7kW precision cooling unit with redundancy backup, and the room has held 21°C ever since — even during August.

Harrow and Stanmore sit in the northwest of Greater London, close to our Uxbridge base. Harrow town centre has a busy commercial high street, a significant education sector (including Harrow School), and a dense residential population. Stanmore is more suburban but with notable commercial activity around the Jubilee Line station and the Royal National Orthopaedic Hospital.
