Can a Furnace Leak Carbon Monoxide When Turned Off?

Carbon monoxide (CO) leaks are a serious concern for homeowners in Aurora, CO, and the surrounding areas, including Dupont, Englewood, Littleton, and Parker. Done Plumbing, Heating, Cooling and Electric, a trusted HVAC company serving the area since 1999, is here to help you understand the risks and prevent CO leaks in your home.

What is Carbon Monoxide and Why is it Dangerous?

Carbon monoxide is a colorless, odorless, and tasteless gas that is highly toxic to humans and animals. It is produced by the incomplete combustion of fossil fuels, such as natural gas, propane, and oil. Exposure to high levels of CO can cause severe health problems, including headaches, dizziness, nausea, and even death.

How Can a Furnace Leak Carbon Monoxide?

Furnaces can leak CO due to various reasons, such as a cracked heat exchanger, improper ventilation, or a malfunctioning burner. A cracked heat exchanger can allow CO to escape into the air, while improper ventilation can cause CO to build up inside your Arvada, Broomfield, or Castle Rock home. A malfunctioning burner can produce excessive amounts of CO, which can leak into the living space.

Can a Furnace Leak Carbon Monoxide When Turned Off?

While it is less common, a furnace can still leak CO even when it is turned off. If there is a crack in the heat exchanger or a problem with the flue pipe, CO can continue to leak into your Commerce City, Golden, or Lafayette home. Additionally, if the furnace is not properly ventilated, CO can build up inside the unit and leak out when it is turned back on.

Signs of a Carbon Monoxide Leak from Your Furnace

Some signs of a CO leak from your furnace include a yellow or flickering flame, soot buildup around the unit, and a strong odor similar to rotten eggs. Physical symptoms of CO poisoning include headaches, dizziness, nausea, fatigue, and shortness of breath. If you suspect a CO leak in your Westminster, Brighton, or Henderson home, evacuate immediately and call your local fire department or a professional HVAC technician.

The Importance of Carbon Monoxide Detectors

CO detectors are essential for protecting your family from the dangers of CO poisoning. Install CO detectors on every level of your Wheat Ridge, Centennial, or Highlands Ranch home, including the basement and near sleeping areas.
