What is a high-velocity system?

Same comfort, a smarter delivery. Small-duct high-velocity systems fit where conventional HVAC can’t.

Compact mini-ducts

Flexible 2-inch supply tubing routes through walls, ceilings, and tight spaces, no bulky soffits or chases.

Draft-free, even temperatures

A gentle aspiration effect blends the air so rooms stay evenly comfortable, with no hot or cold spots.

Whisper-quiet

Insulated tubing and a quiet air handler mean you barely hear it running.

What it means for your home.

  • Comfort without a renovation. Mini-ducts fit into existing homes with minimal disruption, no dropped ceilings or torn-up walls.
  • Preserves your home’s character. Small, discreet outlets blend into ceilings and floors, ideal for historic and high-design homes.
  • Even, quiet comfort. The high-velocity aspiration effect delivers draft-free, consistent temperatures room to room.
  • Heating and cooling in one system. High-velocity systems handle both, so you get year-round comfort from a single solution.

Questions, answered.

Is a high-velocity system the same as Unico?

Essentially, yes. Unico is the leading brand of small-duct high-velocity HVAC. “High-velocity” describes the technology, and Unico is the system we install.

Will it be loud or drafty?

No. High-velocity systems are designed to be whisper-quiet, and the aspiration effect actually reduces drafts and evens out temperatures compared to conventional systems.

Can it heat and cool?

Yes. A high-velocity system provides both heating and cooling through the same compact ductwork.

Is my older home a good candidate?

Often, yes. High-velocity is purpose-built for older and historic homes where running conventional ducts is not practical. We will assess your home and let you know.
