Air Conditioning in Windsor
A Georgian townhouse below the Castle, a Dedworth semi or a Peascod Street hotel — we match you with vetted, F-Gas certified air conditioning engineers who know Windsor's conservation rules. Free quotes.
A historic core with suburbs around it
Windsor's centre is a tightly packed town of Georgian and Victorian buildings in the Castle's shadow, and with Eton, Old Windsor and Datchet it forms one of the largest clusters of conservation areas and listed buildings in Berkshire. Installations here are about invisibility: condensers in rear yards or on concealed flat roofs, pipework inside or down a back elevation, consent settled first. Clewer and Spital add Victorian terraces and inter-war semis where a rear-wall unit is usually fine; Dedworth is post-war estate housing and the easiest install in town; riverside flats need the freeholder's consent first. Peascod Street hotels and shops add commercial plant. Engineers we match cover all of SL4.
Nearby areas we also cover
