Why is it essential to have a carbon monoxide detector near a gas furnace?

Having a carbon monoxide detector near a gas furnace is critical because it serves to alert occupants of dangerous gas leaks. Carbon monoxide (CO) is a colorless, odorless gas that can be produced by the incomplete combustion of fossil fuels, including natural gas used in furnaces. If the furnace is not functioning properly, it may release CO into the home, posing a serious health risk to occupants.

Carbon monoxide inhalation can lead to symptoms such as headache, dizziness, confusion, and even death in severe cases. By installing a carbon monoxide detector, homeowners can receive timely warnings that allow them to take immediate action, such as evacuating the premises and calling for assistance to resolve the issue. This preventive measure is key to ensuring safety in homes utilizing gas appliances.

In contrast, while monitoring energy efficiency, checking furnace pressure, and controlling furnace temperature are important aspects of maintaining a gas furnace, they do not directly address the safety concern posed by carbon monoxide. Only the carbon monoxide detector specifically serves the purpose of detecting dangerous gas leaks, making it essential for safety near a gas furnace.
