Why efficient ductwork matters

Provided by Networx.com

True or false? When it comes to heating and cooling equipment for your home, your HVAC system itself is what's important; ductwork and vents play an insignificant role. The answer is: False! Simply put, if you install ducts and vents incorrectly, you will end up paying big bucks to heat or cool the great outdoors ... and even worse, you may put your family's health at risk. Ditto if you fail to maintain your ductwork in good shape.

Potential Problems

Reduced air distribution efficiency. Duct and vent installation is a complex business, which is best left in the hands ofa reliable HVAC contractor. If it is not performed properly, the efficiency of your HVAC system, no matter how new or expensive, will be greatly reduced. The US Department of Energy reports that many American homes contain air distribution systems (that is, ductwork) which are operating at only 60-75% of capacity or less. In simple terms, that means you may be getting a lot less heating or cooling than you're paying for.

Reduced indoor air quality. If your ducts begin to leak, they allow contaminants such as bacteria, molds, and common allergens to enter the piping system. From there, the unhealthy air may be distributed throughout your home. This can cause or aggravate a number of illnesses, including infections, allergic rhinitis, respiratory problems, chronic headaches, and more.

Pressure imbalance. Leaky ductwork can also lead to pressure imbalances, which will draw outdoor air into the home and force already-conditioned air outdoors. Beyond a loss in HVAC energy, this uneven pressure has the potential tocause backdrafting of lethal carbon monoxide by fuel-burning appliances, such as natural gas heaters or wood stoves.

Vent and Duct Install

ACCA standards. Whether you are planning to install ductwork in new construction or retrofit to an older home, choose a system that was designed to ACCA(Air Conditioning Contractors of America) or equivalent standards.

Professional install. Have an experienced HVAC contractor install your air distribution system. The professionals have the know-how to follow up-to-date best practices and maintain the system's mechanical integrity.

Location. Locate ducts in a conditioned space whenever possible. This may not be feasible with a retrofit, in which case you should ensure that they are adequately insulated. R-value should be at least 8.
