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.

High-velocity systems use higher pressures and smaller diameter ducting

Affordable Comfort is proud to install and service high-velocity HVAC systems for homeowners in Barrie and Collingwood. Standard low-velocity systems utilize supply piping of 5 to 6 inches and 4x10 inch supply registers. Hi-velocity systems use only 2 to 2 3/4 inch supply piping and registers. Employing a high-pressure to low-pressure dynamic, it continuously mixes the room air, creating even temperatures from floor to ceiling. This makes the system ideal for retrofits or new construction homes where fewer bulkheads and increased comfort are desired.

The air handlers are small enough to be installed in almost any location, including an attic, crawl space, closet, basement, or mechanical room. For cooling, these air handlers pair with standard condensers, which we support with professional AC repair in Barrie and Collingwood. For heating, they can utilize heat pump condensers with backup sources like hot water 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.
