Sealing and Improving Ductwork
The Environmental Protection Agency has performed large scale tests on hundreds of houses all over the United States. Their reports have demonstrated that in a typical house over 20 percent of the air that moves through the duct system is commonly lost due to leaks, holes, and poorly connected ducts. In separate studies, the Lawrence Berkeley National Laboratory (LBNL) concluded that 25% loss of efficiency due to ductwork issues is typical. However, it is not uncommon to find leakage rates of up to or even over 50%! We’ve tested and observed it in many homes.
EnviroGreen has been testing, repairing, sealing leaky duct-work and improving systems for over ten years. As a leader in energy efficiency testing and verification EnviroGreen specializes in proper techniques, materials, and proven long-lasting methods to repair and/or seal duct-work, and provide superior weatherization upgrades. Of all the energy efficiency improvements that homeowners can pursue when making their homes more energy efficient sealing leaky duct-work is by far one of the most cost-effective improvements they can invest in with the quickest payback and the most noticeable results, yet one of the most over-looked.
Finally, although duct leakage is one of the primary reasons for high energy bills and indoor air quality problems, the condition of the ductwork may also greatly lead to these concerns. Poorly strapped duct-work, kinked and compressed supply-air ducts, sharp bends, unsealed return-air plenums, and degraded insulation wrapping will all reduce the amount of airflow and negatively effect the temperature and over-all performance and life of the air-conditioning system. Unfortunately, proper installation of ductwork is one of the most least-understood and over-looked inceptions by code inspectors.
Repairing and sealing the existing duct-work is also one of the “greenest” improvements that can be made as you are correcting what is already in place rather than tearing out, adding to and/or replacing such is the case with almost all other energy efficiency improvements.
If the property is located in New Orleans, EnviroGreen has created an extremely aggressive pricing structure that may actually result in minimal out-of-costs to the homeowner. Utilizing the incentives from the New Orleans Energy Smart Program, EnviroGreen may be able to seal the duct-work, greatly reduce your summer and winter heating and cooling costs, increase your family’s comfort and indoor air quality at a greatly reduced price.
Building a new home?
Testing duct-work performance during the construction of your new home is also the best time to learn of any potential issues that may exist and before sheetrock is installed. By learning of leakage rates and faulty duct-design early in the constructive stages.
