Common air conditioning faults in Dorking
Breakdowns in summer often involve older units in shop premises and home offices, and parts for less common brands can take longer to source this far from the main depots. 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.
Dorking is a compact market town within the Surrey Hills, with a core of Georgian and Victorian buildings and streets of Victorian cottages and Edwardian semis radiating from it. North Holmwood and the Goodwyns area have post-war estates, while Westcott, Brockham and Mickleham are villages with period cottages and substantial detached houses. New flats have appeared near the stations. Many older homes have thick walls and small rooms, which changes the sizing and placement of indoor units.
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: Dorking town centre and several surrounding villages are conservation areas within the Surrey Hills; visible condenser positions may need consent.
