How To Tell If Your Furnace is Leaking Gas? And What To Do?

As a homeowner, one of the most critical safety concerns you might encounter is a furnace gas leak. This guide will delve into the causes of a furnace gas leak, its warning signs, associated health risks, and the recommended actions to take when you suspect a leak.

Natural gas furnaces are found in many homes across North America. They’re efficient, affordable, and relatively easy to maintain. However, gas leaks can occur, posing potential risks such as illness and home fires.

Primary Causes of Furnace Gas Leaks

Gas leaks can occur in the gas supply line to your furnace, but they are more commonly caused by a cracked heat exchanger. Overheating is the number one cause of a cracked heat exchanger. Overheating can occur when there isn’t enough airflow through the furnace to dissipate heat safely. Causes of restricted airflow include a dirty furnace filter, duct blockages, ductwork that is too small, or a furnace and air handler that is too large for your home1.

Recognizing the Warning Signs of a Gas Leak

Identifying a gas leak early is crucial to minimize its potential risks. Here are the key signs to look out for.

Health Risks Associated with a Gas Leak

Furnace gas leaks release harmful substances into the air, such as carbon monoxide (CO), which can cause symptoms in people who are exposed. CO is a tasteless, odorless, and colorless gas that can be extremely harmful[^5^]. Here are some symptoms to watch out for.

Steps to Take When You Suspect a Gas Leak

If you suspect a furnace gas leak, you should take quick action, even if you aren’t exhibiting any symptoms of exposure to gas or carbon monoxide. Here are some steps to follow.

Get Your Furnace Inspected: Once any emergency leak has been dealt with and your home is safe to enter, you will want to get your furnace inspected before using it again. An HVAC technician can test your system thoroughly for leaks and perform any required replacements or repairs. This will give you peace of mind that a leak is not likely to reoccur any time soon.
