Retrofitting air conditioning without wrecking a period home

Cooling a listed or period property is mostly a routing problem. The equipment is the easy part.

01

Choosing the discreet option

Low-profile ducted fan coils in a ceiling void, feeding linear slot diffusers, remove almost all visual impact. Where void depth is unavailable, a high-wall or floor-standing unit in a joinery recess can be made unobtrusive with the joiner involved early.

VRV and VRF systems allow one condenser to serve many indoor units, which keeps external plant to a single carefully located position.

02

Outdoor units, neighbours and planning

Condenser noise is assessed at the nearest sensitive facade, not at the unit. Acoustic enclosures, anti-vibration mounts and considered orientation usually resolve it. In conservation areas and on listed buildings, screening and reversibility of fixings matter to the consent as much as the sound level does.

03

Routing without damage

Refrigerant pipework, condensate drainage and control wiring all need a path. We survey the fabric, use existing service voids and redundant chimney flues where possible, and agree every penetration with the architect and conservation officer before anything is cut.
