Last winter, every time the heating system started up, my family members started sneezing or coughing. My spouse complained of headaches, and my youngsters were constantly jammed and suffering sore throats. I was having difficulty sleeping, and my eyes felt itchy. I observed that the heating idea seemed to run for longer periods of time and yet the house was a bit cold. Turning up the thermostat didn’t accomplish much. I finally googled my many complaints with the heating system and got suspicious dirty air duct was to blame. When I looked up the Heating and A/C dealers in my local area, I discovered that absolutely few offer professional duct cleaning. I then read reviews to make sure I chose a reputable dealer. I found one that has been in business for over twenty years, maintains an A+ rating with the Better Business Bureau and stands behind their work with 100% delight guarantee. The serviceman came to the house, inspected the air duct and confirmed a problematic buildup of debris. He found dust, dander, pollen, lint, dead rodents, bugs, webs and mold growth. Every time the heating system operated and sent heated air through the duct system, those harmful toxins were getting circulated throughout the house and breathed in by my family. Plus, the accumulation was restricting airflow and forcing the heating system to work harder and use more energy. I’m lucky the wear and tear on components didn’t cause a malfunction and necessitate an expensive repair. I’ve now l earned that it’s a good system to have the duct idea evaluated every few years. Along with dirty ducts, there is the potential for up to 30% of air to escape from leaks at the attachions and holes.
