Sector, area, technical scope and outcome on every case study.
Three multi-circuit refrigeration units serving a building services plant room. R407C top-ups, HP switch replacements, filter dryer renewals and a compressor swap on Unit 2 carried out over a multi-month programme.
Walk-in fridge running hot. Heavily contaminated condenser coil and seized condenser fan motor. Stripped, pressure-washed, fan freed and tested back to operation. Recurring fault documented: condenser sited with restricted airflow; relocation recommended.
Two Follett ice machines down. Diagnosed faulty inlet solenoid valve on one and faulty plug timer on the other. Bypassed the timer to restore the second machine on the day; parts ordered for the solenoid valve.
Kitchen refrigeration unit not operating correctly. Contamination cleaned off the condenser coil and internal sections. Diagnosed condenser fan motor failure as the underlying fault. Replacement fan assembly ordered.
Commercial gas cooker labelled "Danger, do not use" by a previous engineer but still in active use by kitchen staff. Multiple leaking valve taps, undersized supply pipework. Cooker isolated and labelled under the Gas Safety Regulations.
Three-phase chip fryer swap-out. Old unit isolated and stripped, new fryer positioned and connected, full electrical testing, commissioning and thermostat verification. Second fryer on site flagged for unsafe wiring and faulty thermostat.
A previous contractor had wired a commercial heater unit into domestic-grade sockets, leading to cycling and slow connection wear. Replaced with heavy-duty commercial sockets and plug, heater amp readings verified. Separate blast chiller condensate pump fault flagged.
Return visit to fit a replacement condensate pump on a blast chiller. Kinked condensate hose identified downstream as a root-cause risk; additional waste-pipe support added to prevent recurrence. Pump and drainage tested through a full cycle.
Hot water cylinder not regulating. Faulty fused spurs replaced, undersized cabling upgraded to current BS 7671 standard, new thermostat fitted. Full electrical testing and certification.
Single-site work or multi-site portfolios. F-Gas certified, Gas Safe registered. London + south east.
