      Air Conditioning Systems for Brighton and Sussex Properties

      Wall-mounted split systems are the most practical air conditioning solution for homes in Brighton and Hove, where terraced and period properties often rule out ducted options. LGS installs single-room and multi-split systems from approved manufacturers, sized correctly for your room and electrical supply.

      Most single-room installations are completed within one working day, with the indoor and outdoor units commissioned and tested before our engineers leave.
