Preferred Contractor Expertise in High-Velocity Systems
For historic or uniquely designed properties across the greater Chicago area, homeowners no longer have to choose between sacrificing original architecture for bulky central ductwork or sacrificing indoor comfort. Our NATE-certified specialists leverage decades of specialized experience to design and install Unico systems that deliver modern, whisper-quiet cooling with minimal structural impact.
Small-Duct Flexible Architecture
Utilizes flexible two-inch mini-duct supply tubing that weaves through existing wall cavities, floors, and ceilings without requiring intrusive soffits or drywall destruction.
Aspiration Comfort
High-velocity air delivery creates a gentle suction that draws existing room air into the stream, completely mixing air for consistent floor-to-ceiling temperatures without drafts.
Certified Unico System Maintenance
Precision maintenance and diagnostic care tailored specifically to high-velocity air handlers, specialized coils, and acoustic sound-deadening supply lines.
Why Choose a Unico High-Velocity System?
Traditional HVAC systems rely on large, rigid metal ductwork that causes major aesthetic compromises in historic structures. Unico small-duct technology eliminates these barriers while offering superior humidity control and zero-leak air delivery.

Key Benefits of the UNICO System
30% More Humidity Removal
Specialized cooling coils stay significantly colder than standard units, pulling up to 30% more moisture out of the air for a crisp, cooler feel at higher thermostat settings.
Zero-Leak Efficiency
Flexible, insulated supply tubing eliminates the 25% air loss typical of leaking traditional metal duct seams, ensuring conditioned air reaches living spaces directly.
Preserved Wall Integrity
Flexible tubing weaves around structural joists, eliminating the need to tear down original plastered walls or lower ceiling heights.
Seamless Aesthetic Integration
Subtle circular or slotted outlets blend discreetly into ceilings, floors, or sidewalls to match your interior finishes.
