Indoor air quality (IAQ) is a tricky thing. Numerous studies and papers on the topic have been published over the years, so benefits of good IAQ in buildings are well known — healthier, more productive workers. However, the symptoms related to poor IAQ can be mistaken for symptoms of other illnesses, such as allergies, stress, colds, and the flu. Even after installing IAQ products, it may take time before there is a noticeable difference inside the building. Because of this, building owners can be hesitant to purchase IAQ products. But, there are several factors HVAC contractors can present to increase their chances of making the sale.
According to Rick Tullis, president of Capstone Mechanical in Waco, Texas, the biggest IAQ problem or challenge his clients face is humidity.
