When homeowners think about their indoor comfort, they usually think of their heating and air conditioning: the “H” and “AC” in the acronym “HVAC.” They often forget about the “V” sandwiched in the middle, standing for “ventilation.” But that letter is in the acronym for a good reason—ventilation is essential for comfort in a home and for better indoor air quality. Problems with ductwork in the ventilation system can lead to poor heating/cooling distribution, humidity swings, dusty and polluted air, and a plunge in HVAC energy efficiency.
