Safety Hazards Associated with Malfunctioning Heaters
A malfunctioning heater isn't just an inconvenience – it can also pose serious safety risks. One common hazard is the potential for carbon monoxide (CO) leaks, which occur when heaters burn fuel inefficiently. Carbon monoxide, often referred to as a "silent killer," is an odorless and colorless gas that can cause serious health problems or even be fatal if inhaled in high quantities. Signs of CO poisoning include headaches, dizziness, nausea, and confusion. To reduce this risk, it's essential to maintain your heating system regularly, install CO detectors in your home or business to monitor air quality, and call our team for repairs when you notice something wrong.
