What installing air conditioning in Hersham involves

Typical installs are single splits in bedrooms and loft rooms of semis and bungalows, with larger multi-room systems in Burwood Park homes. Most Hersham 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.

Hersham is mainly a village of inter-war and post-war semis, bungalows and detached houses around the Green and along Molesey Road, with Burwood Park's private estate of large detached homes on its western edge and Whiteley Village's retirement community to the south. There are some newer townhouses and flats near the station and on former industrial land. Bungalows with converted roofs and semis with rear extensions are common, and several larger properties have separate garden buildings.

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.
