Common air conditioning faults in Sevenoaks

Repairs tend to involve multi-split systems in larger homes and older units in commercial premises, with summer demand concentrated in short heatwave periods. The faults engineers see most are units that run but don't cool (dirty filters, a frozen coil or a refrigerant leak), water dripping indoors (a blocked condensate drain or pump), unusual noise from the outdoor unit, and systems tripping the electrics — most are diagnosed in one visit.

Sevenoaks is an affluent commuter town of large Victorian and Edwardian houses around the High Street and the Vine, inter-war and post-war detached homes and semis in the surrounding roads, and substantial properties on private roads such as Kippington and Wildernesse. Riverhead, Dunton Green and Otford have village cores and twentieth-century estates. Flats are mostly near the station. Large detached homes with studies, annexes and garden rooms drive demand for multi-room systems, while period houses need discreet installations.

Re-gassing is only the fix when a leak has been found and repaired — venting refrigerant is illegal, and topping up a leaking system wastes money. For units over 10–15 years old, or those on obsolete refrigerants, a repair engineer should tell you honestly when replacement makes more sense; we can match you with installers for that too.

Conservation note: Sevenoaks town centre, the Vine and several surrounding villages are conservation areas; Sevenoaks District Council may restrict visible units.
