You adore the unique history of your older New England home, but its lack of conventional ductwork makes installing central air a daunting prospect. Disruptive renovations are not the answer. At N.E.T.R., Inc., we specialize in innovative solutions that bring modern comfort to classic homes, preserving their integrity while delivering powerful heating and cooling.

High-Velocity HVAC: The Unseen Revolution in Home Comfort

A high-velocity HVAC, or Small-Duct High-Velocity (SDHV) system, is a game-changer. It utilizes narrow, flexible tubes, merely two inches in diameter, to circulate conditioned air. An air handler propels air at high speed, creating a gentle aspiration effect that ensures even temperatures and eliminates hot and cold spots throughout your home, all powered by an efficient outdoor unit.

Preserve Your Home’s Charm, Upgrade Its Comfort

The primary advantage of a small-duct system is its ability to integrate seamlessly into your home’s existing structure. The flexible tubing can be threaded through walls, ceilings, and closets with virtually no demolition, protecting your original plaster and woodwork. These systems also excel at removing up to 30% more humidity than traditional units—a blessing in New England summers. Plus, with modern sound attenuators and discreet, paintable vents, you get whisper-quiet, highly efficient performance that is felt but barely seen.

While we are New England’s top installer of ductless mini-splits, the right choice depends on your goals. Ductless is perfect for zoned control with visible indoor units. However, if you desire a completely concealed, whole-home central system that provides uniform comfort in every room, high-velocity HVAC is the superior solution. Our experts can help you compare options. Learn more in our guide: Ductless vs. Ducted Air Handlers: Which AC is Right for You?

The performance of an SDHV system hinges on meticulous design and installation. Since 1989, N.E.T.R., Inc.’s certified technicians have mastered complex installations of leading brands like Unico and SpacePak. If you’re ready to experience unparalleled comfort without compromising your home’s character, we’re here to design a custom high-velocity heating and cooling system for you.

Your Questions Answered

Key Questions About High-Velocity HVAC Systems

Considering a modern HVAC solution for your classic New England home? We’ve compiled answers to the most common questions about Small-Duct High-Velocity (SDHV) systems to help you make an informed decision.

What makes a high-velocity system ideal for older homes?

The primary advantage is its minimally invasive installation. The small, flexible ducts can be threaded through existing wall cavities, ceilings, and closets with little to no demolition. This preserves the architectural integrity of historic and classic homes, protecting original plaster walls, woodwork, and floors where bulky traditional ductwork is not an option.

Despite the name, modern high-velocity systems are designed for whisper-quiet performance. Inline sound attenuators within the flexible tubing muffle air noise, making the system’s operation no louder than a conventional central air system and significantly quieter than window units.

High-velocity systems excel at dehumidification, removing up to 30% more moisture than conventional systems—a huge benefit in humid New England summers. The high-pressure airflow also creates superior circulation, which eliminates the hot and cold spots often found with traditional systems, leading to more even, consistent temperatures throughout your home.

Yes. The small-diameter, insulated ducts experience significantly less thermal energy loss than large, uninsulated ductwork common in older traditional systems. This efficiency ensures that the conditioned air reaches its destination at the intended temperature, which can lead to lower energy bills and reduced environmental impact.

A high-velocity system is ideal if you want a whole-home, central system that is completely concealed. It provides even temperatures in every room without visible indoor units. Ductless mini-splits are better if you want room-by-room temperature control (zoning) and are comfortable with a visible indoor unit on the wall or ceiling.

Not at all. The outlets for a high-velocity system are small, subtle, and can be placed discreetly on ceilings, floors, or high on walls. Often just the size of a CD, they are designed to blend seamlessly with your home’s decor and can be painted or stained to match their surroundings.

The performance, efficiency, and longevity of a high-velocity system depend heavily on proper design and installation. Our certified technicians have specialized expertise in these systems, ensuring your unit is designed for your home’s unique layout and installed for optimal performance for years to come.

Absolutely. A high-velocity system is a comprehensive central heating and air conditioning solution. It connects to an outdoor compressor or heat pump, which heats or cools the air before it is distributed throughout your home, providing year-round, whole-home comfort from a single, concealed system.

The team at N.E.T.R., Inc. has extensive expertise installing systems from leading high-velocity brands, including Unico and SpacePak. We ensure every installation meets the highest standards for performance, efficiency, and long-term reliability.
