Retrofitting heating & cooling into an older home
Older homes were never built for ductwork. Solid walls, awkward voids and a sensible reluctance to lose a single wall mean traditional ducted air conditioning is often impractical to retrofit. The good news: there is a system designed for exactly this problem.
Why retrofit is hard with conventional systems
Traditional ducted air conditioning relies on large, rigid ducts. In a new build they are designed in from day one; in an existing home they usually need boxing-in, dropped ceilings or major channels chased through solid walls. The alternative — a wall-mounted split in every room — means visible units throughout and an outdoor condenser or two. Either way, it is disruptive and rarely sympathetic to an older property.
What actually makes a system retrofit-friendly
- Small, flexible ducts that route through existing voids instead of needing big new ones.
- Minimal builders' work — no major structural alterations or weeks of mess.
- One hidden unit rather than a box on every wall.
- A single upgrade that handles heating, cooling and ventilation together.
Small-duct high-velocity: built for retrofit
This is precisely what small-duct high-velocity was designed for. The insulated 50–63mm tubing threads through floors, ceilings, lofts and cupboards with far less disruption than rigid ductwork, and the outlets are small and discreet. Many homes can be fitted in a matter of days rather than weeks, and you keep your walls — no radiators, no cassettes.
Heat, cool and ventilate in one upgrade
Because the system is heat-pump-ready and can include heat-recovery ventilation, a single retrofit modernises three things at once: even, efficient heating; whole-home cooling for those hotter summers; and fresh, filtered air that helps with the damp and condensation older homes often suffer. It is a genuine comfort and air-quality upgrade, not just cooling bolted on.

Can you retrofit ducted air conditioning into an existing UK home?
Traditional rigid ducted systems are often impractical to retrofit because of the space and building work required. Small-duct high-velocity is specifically designed for retrofit — its slim, flexible ducts thread through existing voids with minimal disruption.
How disruptive is retrofitting whole-home heating and cooling?
With small-duct high-velocity it is usually low: the slim ducts route through existing floors, ceilings and lofts, and many homes can be completed in a few days rather than weeks of major works.
Do I have to lose wall space or keep radiators?
No. A small-duct high-velocity system uses small, discreet outlets instead of radiators or wall units, so you reclaim your walls entirely.
Can a solid-wall older house be air conditioned?
Yes. Because the ducts are small and flexible, they can be routed through existing voids rather than needing large channels chased through solid walls, making older homes very achievable.
Will a retrofit system work with a heat pump?
Yes. Small-duct high-velocity is heat-pump-ready, so the same system heats efficiently in winter and cools in summer, and can add fresh-air ventilation.
