Radiator-heated homes have three main cooling paths: a central air handler in the attic with ducts to upper floors, a high-velocity small-duct system, or ductless mini-splits. Ductless is usually the least invasive and adds efficient heat; attic systems hide equipment but need a usable attic and a plan for the first floor.
Technical Consideration
Cooling options for radiator homes
| Option | Best for | Tradeoffs |
|---|---|---|
| Attic air handler + ducts | Homes with accessible attics | First floor needs drops through closets |
| High-velocity small duct | Historic interiors | Higher cost, some noise, specialist installers |
| Ductless heat pumps | Most rowhouses and twins | Visible heads; adds efficient heat |
How do I cool the first floor with an attic system?
Supply ducts are dropped through closets or chases, or a second small system serves the lower floor.
Returns are often the hardest part to route.
Is high-velocity worth it?
It uses small flexible tubes and round outlets that preserve plaster and trim.
It costs more and needs an installer experienced with the system.
Why do many owners choose ductless?
It is fast to install, adds heat pump heating, and avoids opening walls.
Placement and head count must be planned to keep closed rooms comfortable.
