As the crisp Illinois air begins to replace the humidity of summer, many of us are turning our attention to cozy sweaters and preparing our homes for the upcoming heating season. At Summit Heating & Cooling, we believe that true home comfort starts with safety. While you are busy checking your furnace filters and sealing windows, there is one vital task that should be at the top of your September to-do list: evaluating your home’s carbon monoxide (CO) safety measures. Because carbon monoxide is colorless, odorless, and tasteless, it is often called the 'silent killer.' As you prepare to rely more heavily on your furnace, taking proactive steps to ensure your home is protected is the most important maintenance task you can perform this month. Why September is the Time for CO Awareness As temperatures fluctuate in Chicagoland, your furnace will soon begin its regular cycle of operation. If there are any issues with your heating system’s combustion process or venting, carbon monoxide can build up inside your living space. September provides the perfect window to inspect your safety equipment before the deep freeze of winter arrives. Actionable Steps for CO Safety 1. Test Your Detectors: Every level of your home, especially near sleeping areas, should have a functioning carbon monoxide detector. Press the 'test' button on each unit to ensure the alarm sounds. If the unit is more than five to seven years old, it is likely time to replace it entirely, as sensors can degrade over time. 2. Check Battery Levels: Even if your detectors are hardwired into your home’s electrical system, many have battery backups. Replace these batteries every September to ensure your protection remains uninterrupted during potential power outages. 3. Inspect Your Venting: Ensure that the area around your furnace and water heater is clear of clutter. Check that your exterior exhaust vents are not blocked by bird nests, leaves, or debris that may have accumulated over the summer. Proper ventilation is essential for safely carrying combustion byproducts out of your home. 4. Schedule a Professional Inspection: A professional tune-up from the team at Summit Heating & Cooling is the best way to ensure your furnace is operating safely. Our technicians perform a comprehensive combustion analysis to verify that your system is venting correctly and burning fuel efficiently, which is the best defense against CO leaks. 5. Know the Symptoms: Familiarize your family with the signs of CO poisoning, which can include headaches, dizziness, nausea, confusion, and fatigue. If your alarm sounds, evacuate the home immediately and call emergency services. By taking these simple, practical steps this month, you can enjoy the changing seasons with the peace of mind that your home is a safe haven for your family. At Summit Heating & Cooling, we are dedicated to helping our Illinois neighbors stay warm and secure all year long. If you have questions about your system’s safety or would like to schedule a professional inspection, our team is here to help. Sources: U.S. Environmental Protection Agency
