I recently noticed that cooking smells not only traveled throughout the whole house but lingered. While the aroma of a meat loaf baking is mouth-watering in the kitchen, it’s extremely unpleasant in the bedrooms. I realized that odors were getting pulled into the ductwork and spread to every room. As I paid closer attention, I found that there was a lot more dust floating around in the air and accumulating on surfaces. I got suspicious that there was a problem with the duct system. We’ve lived in the house for nearly ten years and never had any type of professional duct services performed. I hired a local HVAC company to send a technician to inspect and test the operation of the ventilation system. The tech concluded that there was a significant amount of debris buildup within the pipes. The excessive amounts of dust, pollen, dander, mold and even bugs and webs were blocking essential airflow. Since the maximum amount of air wasn’t reaching the intended destination, the furnace and air conditioner were forced to run longer and work harder. The system was consuming a lot more energy and experiencing greater wear and tear. Plus, every time the heater or air conditioner started up, the contaminants within the ducts were becoming airborne and getting spread into our breathing air. This accumulation of dirt and grim was absorbing odors and carrying them to every room as well. The technician spent a little over an hour completing a thorough duct cleaning process. He used a machine that looked very similar to an industrial sized vacuum cleaner to dislodge mold and bacteria and suck up all of the pollutants.
