Hi-Velocity System

High Velocity AC is a national distributor for Hi-Velocity Systems, a leading manufacturer of high velocity air conditioning and heating systems. Its energy-efficient air delivery system is designed to provide heating, cooling, filtration, ventilation, humidification and dehumidification in a small-duct, high velocity delivery system (SDHV).

The Hi-Velocity SDHV System is different than conventional systems because the supply duct work has a small diameter and is easy to install inside existing walls with minimal remodelling. The flex duct fits inside a typical framed wall without having to disturb the drywall, and the compact fan coil is modular and fits easily in mechanical rooms, closets, attics, and crawl spaces. It is a perfect choice for both new construction and retrofits.

What Makes Hi-Velocity Air Conditioning and Heating Different?

The pressurized small duct system conditions the air quite differently than conventional forced air systems. The high pressure areas and low pressure areas continuously mix the room air, creating even temperatures from floor to ceiling. Air from the uniquely designed round outlets mixes the ambient air thoroughly and eliminates  the hot and cold spots commonly found with conventional systems.

 High velocity air conditioning and heating systems reduce common dust build-up and allergens. The pressurized plenum duct eliminates dust build-up within the duct work, while filters eliminate airborne dust and other allergens from the continuous air circulation.

How Does This Benefit You?

Our innovative fan coil and unique cooling module technology helps create a healthier and more enjoyable indoor living environment, while saving money on monthly operating costs. The velocity air conditioning and heating system can remove up to 30% more moisture from the air than conventional systems, supplying a constant and comfortable room temperature for your home or office.

How We Provide these Benefits
HI-Velocity System Features Hi-Velocity System can Improve your Indoor Air Quality

High Efficiency programmable Energy Smart Motors with Variable Frequency Drive

Even temperature throughout the structure

Our fan coil units are modular and can be installed easily in a variety of orientations, with many available application options for heating and cooling


Our two inch & HE flex duct delivers air under a greater pressure than a conventional system. This increase in pressure forces the mixing of the air in the room, eliminating stratification

Fresh air make-up

Our flex duct is insulated to prevent heat loss/gain and has a sound absorbing inner core to deliver the air whisper quiet


Smaller duct also allows for greater flexibility in installations while saving space


Reduce conditions that promote mold and mildew
