What makes Unico so unique?

  1. The Unico System is much smaller than conventional HVAC systems, eliminating the need for ugly soffits and large, noisy registers.
  2. Because the Unico ducts are a quarter of the size of typical air ducts, they can easily weave through existing ceiling wall and floor cavities without compromising the architectural integrity of your Pittsburg home.
  3. The Unico System offers the perfect solution for homes or buildings with little space for available ductwork. For older homes, new construction projects, and green sustainable construction, Unico gives you total design flexibility and seamless installation.

The Unico System is the only HVAC system endorsed by the National Trust for Historic Preservation. It offers value and comfort in a way no other system can provide.

Enhance Your Indoor Air Quality

The Unico System manages heat loss and air leaks in your HVAC system far better than conventional ductwork. Because the Unico ductwork has one-third the surface area of typical ducting, it has one-third less thermal loss.

The supply tubing is also wrapped with insulation and an outer vapor barrier, keeping nearly all of the thermal energy within the duct.

The Unico ductwork is engineered for simplicity and air tightness. ENERGY STAR® notes that traditional systems can lose up to 25 percent of the airflow they produce because of leaky ductwork. The Unico System loses less than five percent.

The Unico System adapts perfectly to any residential, multifamily, commercial, or industrial setting. It operates like any other central air system—only with more benefits.

Even Temperatures and Less Humidity

Unico’s high-velocity technology means the temperature throughout your Concord home is never greater than two degrees from the thermostat setting.

Unico uses Aspiration technology. Conventional forced-air systems dump air into a room, creating wide temperature swings. The Unico System gently draws air into a room, creating draft-free comfort and even temperatures in every room, wall to wall, ceiling to floor.

The Unico System removes 30 percent more humidity than a conventional HVAC system. You can comfortably set the thermostat higher in the summer, saving you money on energy costs one degree at a time.

A Whisper-Quiet Operation

The Unico System is the quietest HVAC system on the market today, using sound-absorbing insulation to reduce vibrations. The custom ductwork works like a muffler, delivering a near-silent, comfortable performance.

Choose from a wide variety of slotted or round outlets made of wood, metal, and other sustainable materials to fit any decor in your home or business. The outlets come in several colors and can be stained to match a wood floor. Our Air Synergy team can install them on the ceilings, floors, or walls, depending on the design of your home.

Take advantage of superior comfort and control over traditional HVAC systems. Go with Unico.
