What an air conditioning service in Farnham includes
A high proportion of local systems are in owner-occupied detached houses and are serviced annually; hospitality and retail premises in the town centre add seasonal pre-summer checks. A proper service takes 45–90 minutes per unit: filters and coils cleaned, the condensate drain cleared, refrigerant pressures and any leak checked, electrical connections tightened, fans and motors inspected and the system test-run in cooling and heating.
Castle Street, The Borough, West Street and Lion and Lamb Yard make up the retail heart, with offices and studios around the town and the University for the Creative Arts. Farnham Trading Estate, Water Lane and Coxbridge Business Park house trade and light-industrial occupiers. Commercial systems over 12 kW also need a TM44 air conditioning inspection every five years, and larger installations need F-Gas leak checks at set intervals — a maintenance contract keeps both on schedule.
Annual servicing is almost always a condition of the manufacturer's warranty, so keep the report and invoice. If the engineer finds a fault, you get a written quote before any repair — we match repairs 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.
