Do furnaces produce carbon dioxide
Yes, furnaces can produce carbon dioxide as a byproduct of combustion. When natural gas or propane is burned in a furnace, the process produces carbon dioxide as well as water vapour and heat. However, modern furnaces are designed to be as efficient as possible, producing less carbon dioxide than older models. Additionally, many furnaces are equipped with exhaust systems that safely vent the carbon dioxide and other byproducts of combustion outside the home. It’s important to have your furnace inspected and serviced regularly to ensure it is functioning properly and not producing dangerous levels of carbon monoxide or other harmful gases. If you have concerns about your furnace’s safety or the air quality in your home, consult a professional HVAC technician who can provide guidance and make any necessary repairs or upgrades.
