If your modular home is like most in Minnesota today, you and your family create up to 40 pounds of dust a year, just through every day living. In addition, high humidity and temperature can also increase the pollutants.
Cleaning your ducts will dramatically increase the air quality in your home. Dirty ducts can harbor contaminants that could cause serious problems for people with respiratory problems, autoimmune disorders or allergies. Heath effects from indoor air pollutants may include irritated eyes, nose and throat, as well as headaches. A good rule of thumb in determining whether to clean your ducts or not is just simply look at them. If they look dirty they probably need to be cleaned by a professional.
