Common air conditioning faults in Horsham
Summer repairs are mostly residential, with some older commercial systems on the industrial estates and in town-centre shops needing attention. 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.
Horsham has a well-preserved market-town centre with medieval and Georgian buildings around the Causeway, surrounded by Victorian and Edwardian houses near Horsham Park and the station. Roffey and North Heath are mainly inter-war and post-war semis, while Holbrook, Broadbridge Heath and Southwater have large modern estates that continue to expand. Flats are concentrated in the town centre. New-build homes with warm upper floors and extended period houses generate most cooling enquiries.
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: Horsham town centre, including the Causeway, is a conservation area; Horsham District Council may restrict units on visible elevations.
