Common breakdowns we fix in Potters Bar

Our Potters Bar engineers diagnose and resolve these issues every week.

Cold Room Not Holding Temperature

A frequent Potters Bar callout. Caused by failing door seals, iced-up evaporators, low refrigerant charge or a worn compressor.

Our fix: Pressure test, leak trace, regas where compliant and replace failed components — usually same-day.

AC System Blowing Warm Air

Common in Potters Bar offices and retail units. Typically a refrigerant leak, blocked condenser or failed sensor.

Our fix: Full F-Gas leak trace using electronic detection, repair and recharge to manufacturer spec.

Ice Build-up on Evaporator

Indicates a defrost circuit fault, low charge or restricted airflow — risks stock loss across Potters Bar kitchens.

Our fix: Full defrost diagnostic, timer/heater replacement and airflow correction.

Display Cabinet Warm Spots

Multideck and serve-over cabinets in Potters Bar shops lose efficiency due to dirty condensers, faulty fans or door curtain issues.

Our fix: Deep clean, fan replacement and night-blind / strip-curtain audit.

Ice Machine Producing Cloudy or No Ice

Caused by scale build-up, failed water inlet valves or thermostat drift — high impact for Potters Bar bars and restaurants.

Our fix: Descale, hygiene clean and component swap; we service Hoshizaki, Scotsman and Manitowoc.

Cellar Cooler Tripping Out

Pub cellars in Potters Bar often suffer compressor short-cycling from high ambient temps or condenser blockage.

Our fix: Condenser clean, remote condenser relocation if needed, and electrical fault diagnosis.
