The answer is simple: because they get dirty over time and they have the potential to contain large amounts of dust and particulates. Cleaning them will boost your HVAC efficiency.
According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating or cooling is wasted. Contaminants in the heating and cooling system cause it to work harder and shorten the life of your system. Although filters are used, the heating and cooling system still gets dirty through normal use. When an HVAC system is clean, it doesn’t have to work as hard to maintain the temperature you desire. As a result, less energy is used, leading to improved cost-effectiveness.
Indoor air quality is one concern that building managers and building inhabitants have when they decide to investigate HVAC system. Through normal occupation in a building, we generate a great deal of contaminants and air pollutants, such as dander, dust, and chemicals. These contaminants are pulled into the HVAC system and re-circulated 5 to 7 times per day, on average. Over time, this re-circulation causes a build-up of contaminants in the ductwork.
While a contaminated HVAC system doesn’t necessarily mean unhealthy air, the situation may contribute to larger health issues or harboring contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders or some environmental allergies.
