Common air conditioning faults in Farnham
Repairs are often to units eight to twelve years old in home offices and conservatories, where capacitors, fan motors and slow refrigerant leaks are the usual faults. 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.
Farnham's Georgian town centre is ringed by very different neighbourhoods. Hale and Heath End have tight rows of Victorian and inter-war terraces and semis, Wrecclesham and Rowledge offer village housing with larger gardens, and The Bourne and the lanes towards Tilford contain substantial detached homes, many with outbuildings and annexes. Newer estates have appeared at Badshot Lea and on former MoD land. Older solid-walled houses in the centre heat up quickly and have limited scope for discreet pipe runs.
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: Farnham's Georgian centre is a large conservation area with many listed buildings; external units normally need careful siting and may need consent.
