From Liisa O'Neill, Department of Energy, Office of Public Affairs:Who knew leaks could be costing Americans $5 billion every year? And that's not water leaks—it's leaks you can't even see. Typical air duct systems, both residential and commercial, typically lose 25-40 percent of heating and cooling energy, accounting for billions added to utility bills.But what if there was a simple mist that...
