What installing air conditioning in Brighton involves
Installers here spend much of their time on flats and converted houses, negotiating freeholder consent and finding acceptable positions for outdoor units on rear walls, roofs and lightwells. Most Brighton 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.
Brighton and Hove's housing is famous for Regency and Victorian terraces and squares, a great many of them divided into flats, with Hanover and the streets behind the seafront full of small terraced houses. Preston Park, Withdean and Hove have larger Victorian and Edwardian villas, while Patcham, Hollingbury and Woodingdean are inter-war and post-war suburbs of semis and bungalows. Flats with no private outdoor space and listed seafront buildings make condenser siting and consent the defining issues here.
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: Much of central Brighton and Hove is covered by conservation areas with numerous listed buildings; external units on visible elevations commonly need consent.
