Lower Energy Bills Through Duct Cleaning and Sealing?
Do the costs of energy seem to be absorbing more and more of you budget? If so, there are a number of ways you can improve household energy efficiency and put those energy dollars back in the bank. From upgrading heating and cooling components to simple system maintenance, the options are unlimited. One often overlooked aspect of the heating and cooling system is ductwork. There are a number of factors that can affect the efficiency of your ductwork, including poor design, improper installation, and leakage. In fact, leaky ductwork can cost you as much as 20 percent of the conditioned air that runs through your system. This is a significant drain on your annual energy costs. What's the solution? Duct sealing, when done properly, can reduce energy loss while improving household comfort and energy savings. Often, homeowners are able to seal accessible regions of their ductwork using metal tape and duct mastic. Of course, for those harder to reach areas, professional consultation is recommended. Not unrelated is duct cleaning. This process can also help reduce energy costs by improving the performance of your heating and cooling systems. How? Duct cleaning removes harmful dirt and debris that is not only harmful to the health of your family, but to the efficiency of your heating and cooling system. Left unattended, this excess buildup of dust and other contaminants can restrict air flow, clog filters and reduce the efficiency of heating and cooling components. The added strain on your system can cause energy costs to soar. What's more, it can lead to unnecessary damage and takes years off of the life of your system. In addition to improved energy efficiency, one of the main benefits of duct cleaning is improved indoor air quality. Airborne contaminants in the home can account for or at least contribute to as many as half of reported respiratory illnesses. With that in mind, it just doesn't make sense to leave contaminants such as mold living and growing within your ductwork. Duct cleaning provides a simple solution to a serious problem, one that have negative implications in terms of your family's health and your heating and cooling system's performance. These are just two of the many ways that you can improve household energy efficiency. Other cost-effective measures include sealing household air leaks and switching to energy efficient lighting.
