Air conditioning and refrigeration for schools and colleges
A classroom of thirty is a large heat load in a building that was often designed for ventilation by opening a window. Add south facing glazing and the room becomes unusable in June, which is exam season.
IT suites and server cupboards are a different problem entirely, running continuously and failing silently over a half term break.
Then there is the kitchen, where refrigeration failure stops the whole lunch service and there is no way to improvise.
Classrooms and halls
Noise is the binding constraint. A unit that a teacher has to talk over will be switched off within a week, which makes fan speed at the working setting more important than headline capacity.
Robustness matters too: controls need to be tamper resistant, and indoor units need to be sited where a thrown bag will not find them.
IT suites, server cupboards and labs
- Continuous duty cooling rather than comfort units on a timeclock
- Duty and standby pairs where a room supports the whole site network
- High temperature alarms that reach somebody during holidays
- Filters on a shorter cycle because the plant never rests
- Science lab requirements checked against the department's own protocols
Catering refrigeration
School kitchens run walk in rooms, uprights and prep counters at high throughput for a short window each day, then sit quiet. That duty cycle hides faults, because a struggling room can still look fine at nine in the morning.
Planned visits in the holidays, with temperature evidence recorded at the product, catch the drift before a September inspection does.
Working in a school
- Planned work scheduled into half terms and summer holidays
- DBS checked engineers, signed in and escorted to site policy
- Hot works and access permits handled with the site team
- Term time attendance limited to genuine breakdowns
- Reports written for the business manager, not just the caretaker
FAQs
Common questions
When should school air conditioning work be done?
Planned servicing belongs in the holidays, with the main visit in the summer break so everything is ready for the autumn term and the following summer. Installations are almost always summer holiday projects for the same reason.
How do you keep classroom units quiet enough to teach over?
By sizing correctly and setting the system to run continuously at low fan speed rather than blasting and cycling. An oversized unit is the usual reason a classroom system ends up switched off permanently.
Our server cupboard overheats every summer. What is the fix?
Usually a dedicated continuous duty unit rather than a comfort unit borrowed from the corridor, plus a high temperature alarm. Where the room runs the site network, a duty and standby pair is the sensible specification.
Do you cover school kitchen refrigeration?
Yes, on the same agreement as the cooling. Walk in rooms, uprights, prep counters and blast chillers, with product temperatures recorded and issued as evidence.
Are your engineers DBS checked?
Yes, where a site requires it, and we work to the school's signing in, escort and safeguarding rules rather than our own convenience.
