THE BRIGHTON & HOVE FIELD GUIDE / AIR CONDITIONING
Air conditioning installers in Brighton & Hove
The exterior can decide whether a flat's cooling plan works at all. In Brighton & Hove, confirm unit position, visible pipework and consent.

START WITH THE PROPERTY
Find a plausible outdoor home for the system
In a Brighton & Hove flat or terrace, check ownership of external space and likely pipe routes before deciding which rooms could be served. A neat indoor plan cannot rescue an impossible outside route.
BEFORE YOU ACCEPT A QUOTE
Price the visible work
Ask for a drawing of external equipment, pipe covers, drainage and electrical supply. Compare the finished appearance and permissions alongside cooling performance; these can be the decisive parts of the project.
