Common air conditioning faults in Kingston upon Thames
Summer repair demand is intense in flats and terraced homes, and older retail and office systems in the town centre need prompt attention to keep trading. 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.
Kingston's borough spans a wide variety of homes: Victorian and Edwardian terraces and mansion flats in Surbiton and Norbiton, inter-war semis across New Malden, Berrylands and Tolworth, post-war estates in Chessington and Hook, and large detached houses on the private roads of Coombe and Kingston Hill. The town centre and riverside have many modern apartment blocks. Flats needing freeholder consent, terraces with narrow side access and big Coombe houses each present distinct installation requirements.
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: Kingston Old Town, Coombe, parts of Surbiton and several other areas are conservation areas; the Royal Borough may restrict visible external units.
