Common air conditioning faults in Hersham
Summer repairs are mostly residential, with some call-outs to older commercial units on the trading estate. 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.
Hersham is mainly a village of inter-war and post-war semis, bungalows and detached houses around the Green and along Molesey Road, with Burwood Park's private estate of large detached homes on its western edge and Whiteley Village's retirement community to the south. There are some newer townhouses and flats near the station and on former industrial land. Bungalows with converted roofs and semis with rear extensions are common, and several larger properties have separate garden buildings.
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.
