High-velocity systems
High-velocity systems use higher pressures and smaller diameter ducting
Standard low-velocity systems utilize supply piping of 5"- 6" and 4"x10" supply registers. Hi-velocity systems are only 2" - 2 3/4" supply piping and registers. Employing a high pressure area to low pressure area dynamic, it continuously mixes the room air, creating even temperatures from floor to ceiling. This makes this system ideal for retrofit or new constructions homes that want less bulkheads and increased home comfort.
The air handlers are small enough that they can be installed in almost any location, whether in an attic, crawl space, closet, basement or mechanical room. For cooling applications the air handlers can be used with any standard air conditioning condenser. For heating applications they can utilize heat pump condensers with backup sources of either hot water heating, or electric elements.
Why Use a High-Velocity HVAC System?
Ideal for limited space and retrofits
High-velocity systems use small diameter ducting that can be routed through walls, floors, and ceilings with minimal disruption. This makes them well suited for older homes, renovations, and projects where traditional duct work would require bulkheads or major structural changes.
More even temperature distribution
By delivering air at higher pressure and mixing room air continuously, high-velocity systems reduce hot and cold spots. This results in more consistent temperatures from floor to ceiling compared to standard systems.
Flexible heating and cooling options
High-velocity systems can be paired with air conditioners, heat pumps, and supplemental heating sources. This flexibility allows them to integrate with a wide range of HVAC configurations without requiring oversized equipment.
FAQs
- What is a high-velocity HVAC system? A high-velocity HVAC system uses small diameter ducts and higher air pressure to distribute heated or cooled air more evenly throughout a space.
- Are high-velocity systems louder than standard systems? When properly designed and installed, high-velocity systems operate quietly. Noise issues are typically related to improper sizing or installation, not the system type itself.
- Can high-velocity systems be installed in existing homes? Yes. High-velocity systems are commonly used in existing homes where installing traditional duct work is difficult or impractical.
- Do high-velocity systems work with air conditioning and heating? Yes. High-velocity systems can be used for cooling with standard air conditioners and for heating with heat pumps, hot water coils, or electric elements.
- Are high-velocity systems energy efficient? High-velocity systems can be very efficient when properly designed. Even air distribution helps systems reach target temperatures faster and maintain consistent comfort.
