Small duct, high-velocity systems

Looking to improve your indoor comfort without major remodeling or bulky ductwork? A small duct, high-velocity (SDHV) system might be the perfect solution.

SDHV systems offer a modern way to heat and cool your home or business by using small, flexible ducts that fit where traditional systems can’t — like inside existing walls, crawlspaces, or ceilings. Unlike standard HVAC systems, which rely on large metal ducts and big vents, SDHV systems deliver air through narrow, insulated tubes that quietly and efficiently circulate air throughout every room.

Why do people love SDHV?

Quiet comfort
Thanks to special sound-dampening materials, SDHV systems run quietly, meaning you’ll feel the comfort but barely hear it.

Space-saving design
The small ducts and compact air handler take up less space, making them ideal for historic homes, homes with HVAC equipment that doesn't currently include ductwork, or businesses with limited mechanical space.

Even temperatures
By using high-pressure airflow, SDHV systems eliminate hot and cold spots, delivering consistent temperatures from floor to ceiling and room to room.

Improved air quality
Many systems offer built-in options for air filtration, humidification, and dehumidification, reducing dust, allergens, and excess moisture.

Energy efficient
With less surface area and tighter connections, SDHV systems tend to lose less air compared to traditional ducted systems, potentially helping lower energy use and costs.

Who should consider it?

• Homeowners looking to add central air without tearing up walls or ceilings. These homes in our area are often heated with electric baseboard heat.
• Business owners interested in space-saving, energy-efficient climate control for offices or retail spaces.
• If you live in an older home or have limited space for ductwork, SDHV could be a smart choice.
• It is gaining popularity in new custom homes where design flexibility is important.

Keep in mind, if you determine that an SDHV system is right for your home, the system should be installed by a trained professional.

With SDHV technology, you can enjoy quiet, even, and efficient comfort — no matter the size or age of your home or building.
