Common air conditioning faults in Windsor
Hospitality premises generate year-round repair work and summer peaks, and older units in historic buildings are often replaced like-for-like to avoid fresh consents. 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.
Windsor's centre is a tightly packed historic town of Georgian and Victorian buildings around the Castle, with Clewer and Spital adding Victorian terraces and inter-war semis. Dedworth is largely post-war estate housing, and Old Windsor, Datchet and Eton Wick are villages with period cottages and larger homes. There are modern flats near the river and the stations. Listed and conservation-area properties need careful, often rear-facing installations, while Dedworth and Spital homes are more straightforward.
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: Windsor town centre, Eton, Old Windsor and Datchet are conservation areas with many listed buildings; external units frequently need consent.
