Common breakdowns we fix in Harrow
Our Harrow engineers diagnose and resolve these issues every week.
Cold Room Not Holding Temperature
A frequent Harrow 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 Harrow 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 Harrow kitchens.
Our fix: Full defrost diagnostic, timer/heater replacement and airflow correction.
Display Cabinet Warm Spots
Multideck and serve-over cabinets in Harrow 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 Harrow bars and restaurants.
Our fix: Descale, hygiene clean and component swap; we service Hoshizaki, Scotsman and Manitowoc.
Cellar Cooler Tripping Out
Pub cellars in Harrow 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.

What Harrow customers say
Trusted by restaurants, retailers and offices across Harrow HA1.
"Our walk-in freezer failed on a Saturday lunch service. Frostline had an engineer on-site in 90 minutes and the unit was back to temperature before evening covers. Lifesaver for our Harrow restaurant."
