High-velocity central air systems use a high-speed airflow through smaller than usual ducts to deliver conditioned air throughout your home. These systems are engineered for situations where standard central air ductwork isn’t practical like older homes, historic buildings, tight crawlspaces, or custom renovations. They give you the comfort and control of central air, with fewer visible components and less wall or ceiling alteration.
Compact. Powerful. Perfect for older homes and tight spaces.
When ductwork is limited, walls are thick, or you want modern comfort without major renovations — our high-velocity central air systems bring whole-home heating & cooling with minimal disruption.
How High-Velocity Works
- A compact air handler resides in an attic, basement, closet or crawlspace
- From it, small-diameter flexible ducts run through existing wall cavities, ceilings or floors rather than large trunk ducts
- Conditioned air is delivered at higher speed into rooms, mixing with the ambient air to create even temperatures and reduce hot/cold spots
- The system design minimizes the need for tuck-ins, bulkheads, or major remodel work often associated with traditional duct retrofits
Why Homeowners Choose High-Velocity
- It fits easily in older or custom-designed homes where standard ductwork would be invasive or impossible
- Minimal disruption: Because the ducts are small and flexible, we can install through existing walls/ceilings with far less mess than conventional systems
- Consistent comfort: High-velocity systems provide uniform temperature control and fewer drafts because of the mixing effect of faster-moving air
- Improved humidity control: Some systems remove more humidity than conventional air conditioning, improving comfort and air quality
- Quiet and discreet: Equipment is compact and outlets can be styled to blend with your décor, making the system more visually subtle
Is a High-Velocity System Right for Your Home?
Consider high-velocity if:
- You live in an older home or historic building where running large ducts would damage walls or architectural features
- You have limited space for ductwork or wish to avoid bulkheads and visible registers
- You want the comfort of central air but your home currently uses baseboard, radiator, or window units
- You’re planning a remodel or basement refinishing, attic or addition and need a practical HVAC solution
