Common air conditioning faults in Farnborough

Repairs split between office and industrial systems that need prompt attention and domestic units during summer peaks, with older commercial plant on R410A and earlier refrigerants increasingly expensive to maintain. 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.

Farnborough is largely a twentieth-century town: Cove and Southwood are dominated by post-war and 1980s estates of semis, link-detached and detached houses, while North Camp and the streets around Farnborough Street have Victorian and Edwardian terraces. Farnborough Park and the roads near the hill have larger detached homes, and the town centre and former aerospace land have gained modern flats and townhouses. Typical jobs involve upstairs bedrooms in estate houses and home offices, with reasonable side and rear access for outdoor 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.

Farnborough repairs FAQs

A diagnostic call-out in Farnborough is typically £80–£150, minor fixes £80–£200, and parts such as capacitors or fan motors £150–£350 fitted. A leak repair with re-gas runs £250–£600.
Often yes for a breakdown in summer — engineers matched through Air Con Surrey typically respond within 24–48 hours and faster for urgent jobs, subject to availability. Commercial systems with business-critical cooling can usually be prioritised.
If the unit is under 10 years old and the repair is under half the cost of a new system, repair is usually sensible. Older units on obsolete refrigerants, or with compressor failures, are often better replaced — a new single split costs £1,500–£3,000 fitted.
