As the colder weather approaches, I’ve had occasion to talk with clients about Indoor Air Quality (IAQ). So much of the comfort of our homes in the winter depends on the proper installation of an HVAC system, with appropriately sized and located vents, and ducts that don’t leak. On average, 30% of ducts leak in the U.S. For some good summary information, I suggest you read material from Build it Green, a locally-founded non-proft organization whose stated mission is “to promote healthy, energy and resource-efficient buildings in California.” Clicking here will take you to their four-page Indoor Air Quality fact-sheet, with a good discussion of the issues involved in excess moisture, and the need for ventilation and filtration.
Another great source for instructions for sealing ducts and adding insulation is through the Energy Star program, sponsored by the EPA. Sealing the building envelope can save you an average of 20% of your utility bills. They have DIY guides to sealing leaks that you may not have thought of, as well as sealing the furnace ducts and adding insulation. Click here to access their information.
