A Small Duct System May Just be the Solution to Your Heating/Cooling Woes.

If your home is short on space to accommodate the large ductwork necessary to install a traditional heating and cooling system, don’t fret. Today’s homeowners have more options for improving home comfort than ever before. Small duct systems are an excellent way to add heating and cooling to homes with limited space. The knowledgeable and experienced staff at H & H Heating & Cooling have the information you need to determine if a small duct system might be a good fit for your home.

What is a Small Duct HVAC System?

Small ducts systems, or small duct high velocity (SDHV) units, use flexible air supply tubes that are smaller than traditional ductwork to move air throughout your home. Despite their small size, however, they are capable of delivering the same level of heating and cooling as much larger conventional systems. Heated and cooled air can be provided by a heat pump or a geothermal unit and is distributed via a small, high-capacity fan. SDHV systems can also be paired with boilers, electric, and radiant floor heating.

What Do Small Duct Systems Look Like?

Installing an SDHV unit won’t disrupt the look of your home indoors or out, and does not require extensive modifications. This makes them an excellent solution for small modern homes, as well as historic buildings. Equipment is about one-third the size of standard systems, fitting easily in attics, crawlspaces, existing wall/floor cavities, and small closets. Ducts are only 2-3.5inches in diameter and may be mistaken for small pot lights without close examination; other installations use slotted vent configurations. Unlike traditional systems, due to the small size of the outlets, more are required. Because they can be colored, painted, or wallpapered to blend in with their surroundings, they often go unnoticed, however.

Day-to-Day Life with a Small Duct System

Because of the small diameter of SDHV units, they deliver conditioned air at higher pressure or velocity than traditional systems. This rapid introduction of air creates a vacuum, helping evenly distribute air to eliminate hot and cold spots. Properly designed and constructed, they are quieter than their conventional counterparts. They also offer added benefits compared to traditional systems, including:

  • Up to 30% better dehumidification.
  • An extremely low rate of heating and cooling loss due to the speed of air transport through ductwork.
  • Improved indoor air quality, as SDHV units require high-efficiency home air filters to protect the tight coils of the systems from dirt and debris, doing a better job of filter allergen-causing bacteria and microorganisms from the air.
