Put simply, a low-load home is one which needs less HVAC output to satisfy the thermostat’s setpoint temperature. By definition, it is tighter (i.e. well-insulated) and has a relatively smaller footprint and, therefore, requires less work and output from the HVAC system. Problems arise when builders or installing contractors design HVAC systems to a higher load requirement than needed in a low-load environment which can lead to poor Indoor Air Quality (IAQ), poor humidity control (which can lead to potential mold growth or structural degradation), lack of proper air mixing and dispersion – in short, poor comfort for occupants.

Better Air Distribution

Lower loads require lower airflow. Unico’s air delivery method uses a lower volume of air moving at a high velocity, which results in aspiration. In contrast to the “dump and throw” method of traditional central air systems, aspiration creates a gentle suction around the delivery outlet, drawing the room’s air into its stream of cooled air, providing better comfort to occupants by eliminating drafts and hot/cold spots, and resulting in even temperatures from ceiling to floor, room to room.

Better Humidity Removal

The construction of The Unico System cooling coil allows more air to flow across its surface, removing 30% more moisture – or, humidity – than conventional HVAC systems. This is not only beneficial in geographies with humid climates, but also offsets the humidity caused by activities within homes (cooking, bathing, etc.). Occupants in homes equipped with The Unico System can feel just as comfortable at higher thermostat settings, adding to the system’s energy efficiency.

Better Indoor Air Quality (IAQ)

Because Unico ducting is so tightly sealed, there is less opportunity for the entrapment and dispersal of allergens or other contaminants. Fresh outside air is easy to incorporate into the Unico System air handler and zoning is a snap with either proprietary or off-the-shelf damper systems and controls.

Whisper Quiet

Unico System supply tubing is designed to be as quiet and efficient as possible, with a nylon inner core and insulation that absorbs sound. Unico air handlers are designed to isolate noise and vibration, with closed cell, sound-deadening insulation. Together, they bring decibels levels to the equivalent of a soft whisper. While occupants feel the comfort The Unico System provides, they hardly notice it’s running.

Better Energy Efficiency

Conventional forced-air systems can lose as much as 40% of their conditioned air, especially when ducting is located in an unconditioned area like an attic or crawlspace. But The Unico System's smaller, tighter ducts lose virtually none of their conditioned air and don't experience the degree of thermal loss associated with traditional HVAC systems. And Unico blowers are available with programmable, variable speed and Electronically Commutated Motors (ECMs) that use less electricity than their conventional counterparts. Unico air handlers are also compatible with virtually every major brand of outdoor condenser or heat pump. When you or your contractor choose a high-SEER outdoor unit, you can be sure The Unico System is providing actual delivered efficiency and not losing conditioned air to duct leakage or thermal transference.

Better Space-Savings & Aesthetics

Homeowners love the fact that the small size of The Unico System means they don't have to sacrifice precious living space to soffits, dropped ceilings or other concealments required with traditional ducted systems. Outlets, either round (2- 2.5-inch inner diameter/ 5-inch outer diameter) or slotted (1-inch by 8-inch) are available in a variety of painted plastic finishes or stainable wood species to blend into any style of decor. They can even be wall papered to become virtually invisible in their surroundings, providing better aesthetics than conventional rectangular registers. Architects, builders, and installers love the fact that The Unico System's small size and modular nature allow for freedom of design and make it much easier and faster to install over its conventional-sized counterparts, making it a natural for both new construction and retrofit applications.
