The mini-duct air distrubution system removes approximately 30% more moisture in the cooling mode than conventional systems. This results in cooler, dryer air. Lower humidity levels create a more comfortable environment, even at a higher temperature.
The mini-duct air distrubution system can be installed in any home, regardless of the design, construction, or age with little or no remodeling.
Ease of Implementation
The mini duct air distribution system is quick and easy to install. The small flexible, insulated tubing is designed to fit the existing structure without major remodeling. The tubing requires approximately 1/10th the space of conventional central air conditioning.
High velocity air distribution systems are distributed by certified contractors, or may be purchased directly from the manufacturer or distributor. Howecer, it is important to note that some heating and cooling professionals are unfamiliar with high velocity ducts. The systems commonly require a greater number of outlets--(about 5 outlets per ton of cooling, or one outlet for every 2400 BTUs of heating), --adding to material costs and installation time.
The initial costs for Mini-duct systems is greater than their conventional counterparts.
The Air Conditioning and Refrigeration Institute (ARI) certifies high velocity air distribution systems for use with numerous heat pumps, air conditioners, and heat sources.
High velocity heating and cooling systems should be installed by manufacturer-authorized heating and cooling professionals. Small diameter ducts may be run through penetrations in floor joists, unlike systems with standard-sized ducts. Placing air outlets in areas of a room, such as in corners of a ceiling, or beside windows or doors, can result in a high velocity output that improves room air mixture without causing discomfort to occupants.
the mini-duct systems are typically warranted for a period off 1 year from the date of installation. However, some parts of the system may not be covered by this warranty.
Manufacturers claim that dehumidification with high-velocity air distribution is better than for conventional forced-air systems. In the air conditioning season, lower humidity levels can allow occupants to feel comfortable with the thermostat set at higher temperature, resulting in reduced energy costs. In both heating and cooling seasons, delivering air at higher velocity through smaller supply lines mixes the room air more effectively, reducing temperature stratification, and eliminating the need to place duct outlets at windows or exterior walls to avoid hot/cold spots.
For installation in existing homes, the 2" supply lines can be fed through joists, wall cavities, and around common obstructions, so that costly and disruptive structural alterations can be avoided. This can be beneficial in applications where existing architectural features, like plaster moldings, would be difficult to change or duplicate. For this reason, high-velocity systems can be the most cost-effective option for retrofits, although they may be more expensive than conventional ductwork in new construction.
