Furnaces of the past had a lot of issues in terms of home safety. Unfortunately, it was once all-too-common for a fire to break out due to a furnace malfunction, or a carbon monoxide leak to make people ill. Today, as you might expect, modern engineering has led to a much safer furnace.
Remember that anytime natural gas is used in an ignition system, there is a risk associated. However, modern safety switches within furnaces make it far less likely that something like an explosion or leak could occur. Combine this with routine professional inspections of your heater, and you can feel at ease. Read on to learn more about the switches inside your gas furnace that keep you safe and protect the system.
