I am always concerned about indoor air quality in my home. I suffer from severe allergies and am very sensitive to dust, pollen, dander and all sorts of contaminants. If the house isn’t kept extremely clean, I deal with congestion, sore throat, itchy eyes, sneezing and migraines. Vacuuming, dusting and scrubbing with disinfectant are essential but not enough. I need to take constant proactive measures. I know that the heating and cooling system can be helpful or harmful. The furnace and air conditioner both work to filter out allergens. However, if the systems are dirty, they can actually spread pollutants throughout the house. I make sure to have the heating and cooling components professionally cleaned every year. A licensed technician services the furnace in the fall and the air conditioner in the spring, making sure the systems are operating at peak capacity and efficiency before the start of the season. I also make the ductwork a priority. The duct system is responsible for transporting the heated and cooled air to the vents located in every room. If there is a buildup of debris inside the ducts, such as mold, it can be introduced into the breathing air every time the furnace or air conditioner starts up. I always ask the HVAC technician to test the ducts for leaks as well as restricted airflow. The duct cleaning process only takes around an hour and makes a huge difference in air quality of the home. It also promotes greater heating and cooling efficiency and superior comfort. When the ducts are working properly, the home remains at a more consistent temperature.
