Ductless Mini-Split Systems
Ductless mini-splits solve the space problem by eliminating ducts entirely. The outdoor condenser connects to slim indoor air handlers mounted high on walls or concealed in ceiling cassettes. Each unit operates independently, allowing zoned temperature control room by room.
For Ohio City’s climate, look for systems with heat pump capability and cold-climate ratings. Modern mini-splits can extract heat from outdoor air down to -13°F, providing efficient winter heating without a separate furnace. The indoor units require only a 3-inch wall penetration for refrigerant lines and condensate drain. EPA commercial building efficiency programs.
Installation typically takes two days. The outdoor unit needs 12 inches of clearance from walls and 24 inches above for airflow. Condensate drains must tie into existing plumbing per Cleveland plumbing code 4101:1-23-01. Most Ohio City townhomes can accommodate the outdoor unit on a small patio or side yard.
High-Velocity HVAC Systems
High-velocity systems use small, flexible ducts—just 2 inches in diameter—that snake through wall cavities, floor joists, or ceiling plenums. The Unico or SpacePak systems deliver conditioned air at high speed, creating a gentle mixing effect that eliminates hot and cold spots.
These systems work exceptionally well in historic homes where preserving original architecture matters. The small supply outlets can be painted to match walls or installed in less conspicuous locations. A single compact air handler, about the size of a kitchen cabinet, replaces the need for extensive ductwork.
The main challenge is finding space for the air handler. Many Ohio City townhomes can fit it in a closet, above a bathtub enclosure, or in a utility nook.
