Why Your Furnace Smells Like Gas When Turning On

Why Your Furnace Smells Like Gas When Turning On

Every homeowner dreads the moment their furnace emits a strong and potentially dangerous smell of gas upon starting up. In most cases, the source of this smell is propane or natural gas, both of which can create a serious health hazard if not addressed immediately. If you're wondering why your furnace smells like gas when turning on, we have compiled some of the most common reasons to help you determine the cause and get back to enjoying warm and safe heating in your home.

Lack of Maintenance

One of the top reasons why your furnace smells like gas when it is turned on is a lack of maintenance. Your furnace requires regular servicing to ensure that all components are functioning properly and that there are no gas leaks. A certified technician can assess the condition of your system and make any necessary repairs or replacements to ensure the safety of your home. Furthermore, routine maintenance can reduce wear and tear on your furnace, making it more efficient and helping to reduce your energy bills.

Air Flow Issues

Another common reason why your furnace smells like gas when starting up is air flow issues. Poor air flow can occur for a variety of different reasons, including a clogged air filter, blocked air intake or damaged fan blades. In these cases, the furnace will not be able to draw in enough air to fuel the combustion process, causing the gas from the burner to escape into the house instead. A technician can check the air flow of your furnace and identify any issues that need to be addressed.

Clogged Burner

Another source of furnace smells like gas when turning on is a clogged burner. This can occur due to buildup of dust, dirt and debris in the burner compartment. The accumulation of these materials can prevent proper combustion, resulting in the release of gas into your home. A technician can evaluate the condition of your burner and make any necessary repairs or replacements to correct the issue.

Issues with the Pilot Light

The pilot light is a small flame that ignites the burner in a gas furnace. If the pilot light is malfunctioning, the burner will not work correctly, resulting in the release of gas from the furnace. A technician can inspect the pilot light and determine if it needs to be adjusted or replaced.

Defective Pressure Switch

A pressure switch is a safety device that monitors the airflow in the furnace to ensure that it is adequate for the combustion process. If the pressure switch is defective, the furnace will not operate properly, causing the release of gas into your house. A technician can inspect the switch and replace it if necessary.

If your furnace smells like gas when turning on, it is vital that you take measures to address the issue as quickly as possible. These are just some of the common sources of furnace smells like gas, and a certified technician can help you identify the exact cause and make any necessary repairs to get your heating system back in working order.
