What Is a High Velocity HVAC System?
A high-velocity HVAC system is an advanced heating and cooling solution that uses compact components and mini-ducts to efficiently distribute conditioned air throughout your home without traditional ductwork.
How Small Duct High Velocity Systems Work
The main difference between a traditional forced air system and an SDHV mini-duct HVAC system is the air ducts. High-velocity systems use flexible 2-inch ducts connected to a powerful but compact air handling unit. Though it can also integrate with existing cooling and heating equipment to create hybrid systems. The conditioned air from an SDHV system is distributed through the ducts at a higher velocity and then enters the room through discreet outlets.
As the air is distributed throughout the room, it starts a process called aspiration. This constant mixing of air eliminates temperature gradients and maintains a more constant temperature throughout your home.
- Compact air handler with heating and cooling coil
- Insulated main trunk line
- Flexible 2-inch mini supply ducts
- Small round or slotted outlets
- Central return air path
Benefits of Unico & SpacePak High Velocity HVAC Systems
Ideal for Older Homes & Retrofit Projects
A small duct HVAC system allows you to retrofit your home with air conditioning with minimal structural disruption. Walls, plaster, trim, and architectural details can often remain intact.
Minimal Visual Impact
Outlets are typically about 5 inches in diameter or available in slim designs. They also come in a variety of colors or can be color-matched to your home’s ceilings, floors, and walls.
Draft-Free Comfort
Aspiration technology allows a high-velocity HVAC system to eliminate hot and cold spots in your home. Instead of noticeable blasts of air, you enjoy balanced comfort throughout your entire home.
Superior Humidity Removal
High-velocity systems can remove up to 30% more humidity than many conventional systems, eliminating the sticky summer feeling and giving you better indoor air quality.
Space-Saving Design
Mini-ducts can be installed through tight cavities, attics, and basements. This makes them a good choice for homes with limited space or where the space is already finished.
Energy Efficiency
Since the ducts for these systems are smaller and well-insulated, there is less chance of energy loss. These well-designed systems offer efficient airflow and reliable performance.
Quiet Operation
The sound-dampening tubing design of Unico and SpacePak HVAC systems makes them quieter than traditional central air systems. They are often compared to soft background noise.
Where High Velocity Systems Work Best
High velocity HVAC is the best choice for:
- Older homes without existing ductwork
- Historic or landmark properties
- Homes with radiator or boiler heating systems
- Custom or luxury homes
- Homes where preserving aesthetics is important
- Home additions
- Finished attics
- Basements
Every property is different. Service Express evaluates each home carefully to determine whether a high-velocity installation is the right solution, based on your home’s structure, layout, and comfort goals.
Unico & SpacePak Heating & Cooling Options
One of the benefits of using Unico and SpacePak HVAC systems is that they are flexible systems that can be integrated with HVAC equipment, such as:

Is a High Velocity System Right for Your Home?
While high-velocity HVAC has many benefits, it may not be the most appropriate system for every household.
In homes with ample space for traditional ductwork, a conventional forced-air system may be easier to install. But installing the necessary ductwork may mean tearing up floors or walls to accommodate the new system. If that’s the case, a small duct system may be a better option.
It’s important to note that proper load calculation, duct design, and balancing are critical to system performance. As a qualified SDHV installer, Service Express prides itself on proper system design and installation.
