Welcome To Our Site!

HIGH VELOCITY HELPER.com is designed to help provide high quality information and support for people with questions about Small Duct High Velocity Air Distribution Systems (like Unico Systems, SpacePak, and others) typically installed by SDHV Installers for the heating, cooling, and filtration of residential homes and small commercial spaces.
We have almost 25 years of practical experience applying, designing, and successfully installing high performance SDHV Systems. We are not installers and do not solicit installation work. We are simply here to help Homeowners and Installers alike in any way we can.
