What installing air conditioning in Dorking involves

Typical work is a single split for a bedroom or home office in a Victorian or Edwardian house, with extra care taken over external appearance and pipe concealment. Most Dorking homes are fitted with a wall-mounted split system — one indoor unit per room, one outdoor unit on an external wall or the ground — while larger properties and open-plan layouts suit a multi-split or a concealed ducted system.

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.

A good installer starts with a site survey: room sizes and glazing (to size the unit in kW), where the outdoor unit can sit within planning limits, the pipe run, the condensate drain and the electrical supply. Expect a written, itemised quote before any work starts, and an F-Gas logbook and manufacturer warranty registration at handover.

Conservation note: Dorking town centre and several surrounding villages are conservation areas within the Surrey Hills; visible condenser positions may need consent.
