How to spot the gas issue in your furnace

More than eighty million Americans use natural gas to heat their homes.

Gas furnaces need natural gas to provide heating.

When you have an older HVAC system or one that has not been correctly maintained, the possibility of a gas leak is very high. Seals wear out over time, exposing leaks. This most commonly occurs in furnace cracks or had valves. Your HVAC technician should check for cracks during the annual maintenance inspection. It is essential to learn how to spot gas issues in your furnace before it ends up hazardous. When you smell rotten eggs coming from your furnace, it could be a sign of a gas leak. Fortunately, gas companies include mercaptan in their gas so you can smell it. Typically, this substance makes the gas smell like rotten eggs or Sulphur. This is usually a telltale sign of a gas leak in your home. However, if the natural gas in its original state leaks, you would not be able to smell it. Check the color of your pilot flame. The pilot flame should always be burning blue. If the flames turn yellow or orange, it could be a sign that your furnace is producing toxic carbon monoxide gas. Hissing sounds coming from your furnace reveal the possibility of a gas leak. You should turn off your gas valve and furnace immediately and contact your HVAC technician after evacuating your home. You may also be experiencing carbon monoxide symptoms such as trouble breathing, dizziness, increased fatigue, nausea, nosebleeds, and ear, throat, and nose irritation. These symptoms are aggravated if the gas leak in your home is left unattended.
