Key Components

A high-velocity HVAC unit includes many super specialized elements, each playing a role in making the system as strong, efficient, and smart as possible. The air handler is the heart of any high-velocity HVAC system, controlling airflow and temperature all in one unit.

These compact yet powerful handlers are designed to deliver high-pressure air through the mini ducts. The systems directly heat or cool spaces, using insulated tubing to prevent energy loss. This insulation ensures that the air stays at the desired temperature while it moves through the ducts.

This insulation takes the system’s energy efficiency to the next level. This creates a very cost-effective option over time. Circular vents, their other signature design, enable flush installation for a more subtle look.

These vents can be designed to flush mount directly into walls or ceilings, protecting the aesthetic integrity of historic homes. These smaller vents are less obtrusive than large, bulky ones seen in more traditional systems. These units are more easily located in great locations to maximize the benefits of airflow.

Differences From Traditional Systems

One of the most striking contrasts between high-velocity HVAC systems and traditional HVAC systems is the ductwork. High-velocity ducts are up to 50% smaller than conventional duct systems, allowing them to fit into vintage homes where larger ducts won’t work. This smaller size helps reduce thermal loss, as the decreased surface area preserves the efficiency of airflow.

Perhaps the biggest difference that high-velocity systems have to normal systems is the speed of the airflow. These systems are typically designed to move air at high speeds. As such, they heat and cool more quickly, responding instantaneously to changing temperature needs.

This increased efficiency usually leads to lower monthly energy bills, offsetting the initial increased cost. Aesthetic considerations are another aesthetic consideration. Many older homes are filled with beautiful architectural details that the homeowner would like to maintain.

Smaller, less conspicuous vents found in high-velocity systems are less likely to impact aesthetics. This attribute makes them an ideal candidate for retrofitting into unique indoor comfort properties.
