Yes! Even though you have carbon monoxide detectors installed throughout your home, professional testing is an essential safety service for gas-fueled appliances. Low levels of the gas may not be detected by home monitoring, and you may experience symptoms before the device alerts you. When the Cool Experts perform heating maintenance and repairs, we check for leaks and CO buildup. This dangerous gas is odorless and colorless, and it replaces oxygen in your body’s red blood cells. Low CO levels may cause headaches, fatigue, chest pain, dizziness or nausea. Exposure to higher levels of carbon monoxide puts you at risk for major tissue damage and may even lead to death. If you have not had a CO checkup in a while, it’s worth the peace of mind to schedule one.
