How to Avoid Carbon Monoxide Poisoning from a Gas Furnace Leak

A gas furnace is an efficient and reliable way to keep warm during the winter months. But like any gas appliance, it has its possible risks, and one of the most dangerous is carbon monoxide (CO) poisoning. Carbon monoxide is a colourless, odourless gas that is deadly if inhaled in high concentrations. One of the most common sources of carbon monoxide leaks in a home is a faulty gas furnace.

Here at BCRC Heating we know the importance of keeping your furnace maintained to safely and efficiently operate. In this article, we’ll discuss how to prevent carbon monoxide poisoning from a gas furnace leak, the importance of regular maintenance, and steps you can take to protect your family.

The Dangers of Carbon Monoxide: Understanding CO

Carbon monoxide is produced by incomplete combustion of fuel. In a properly functioning furnace, the combustion process works well and gases, including carbon monoxide, are vented safely to the outside. However, if there is an issue with the furnace or the ventilation system, carbon monoxide can leak into your home and endanger everyone inside.

The symptoms of carbon monoxide poisoning depend on the level of exposure. Mild exposure can cause headaches, dizziness and nausea, while more severe exposure can lead to confusion, unconsciousness and even death. Carbon monoxide is not visible and has no odour which is why it is often referred to as the “silent killer.”

Common Causes of a Gas Furnace Leak

Before we discuss leak prevention, we need to understand what can cause a carbon monoxide leak in your gas furnace. Some of the most common reasons for leaks are:

Broken Heat Exchanger

The heat exchanger is an essential part of your furnace which heats the air before it is distributed throughout your home. Over time, the heat exchanger may crack from wear and tear or corrosion. When this occurs, harmful gases like carbon monoxide can leak into the air supply in your home.

Blocked/Damaged Ventilation System

Your furnace has a ventilation system that pushes dangerous gases outside of your home. If the ventilation system is blocked or damaged (by debris, snow or animals), those gases—including carbon monoxide—can accumulate inside your home.

Incorrect Installation or Maintenance

If a gas furnace is not installed correctly or is not regularly maintained, it may not be operating as efficiently or safely as it should. Burner problems, gas pressure or exhaust system problems can cause a carbon monoxide leak.

Pilot light or ignition system failure

If the pilot light or the ignition system is not functioning properly, it can cause the fuel to not burn completely and an increase in carbon monoxide production. If your furnace won’t stay lit, you need to have a professional take a look at it right away.

How to Prevent Carbon Monoxide Leaks in Your Gas Furnace

Now that we know what causes carbon monoxide leaks, let’s talk about the steps you can take to prevent them and keep your home safe.

Schedule Routine Furnace Maintenance

The best way you can prevent carbon monoxide leaks is by having regular maintenance done on your gas furnace. A professional HVAC technician can check all the components of your furnace, including the heat exchanger, burners, and ventilation system to make sure they are functioning correctly.

We recommend that your furnace is inspected and serviced at least once a year, ideally before the heating season begins, at BCRC Heating. We’ll inspect your furnace for any signs of wear, corrosion or damage that could cause a carbon monoxide leak. If we discover any problems, we’ll make the necessary repairs so your furnace continues to operate safely and efficiently.

Install Carbon Monoxide Detectors

Having carbon monoxide detectors in your home is important, along with regular maintenance. These devices are designed to alert you if the carbon monoxide levels in your home become dangerous, giving you time to evacuate and get help.

For maximum protection, install carbon monoxide detectors on each level of your home, particularly in sleeping and living areas. Make sure you test the detectors regularly and change the batteries at least once a year. Replace your detector if it is more than seven years old.

Ensure good ventilation

Good ventilation helps prevent carbon monoxide from accumulating in your home. Ensure that your furnace exhaust vents are free from obstructions like snow, ice or debris. If you have a chimney in your home, have it inspected and cleaned regularly to prevent blockages that could allow gases to build up in your home.

If you have a high efficiency furnace, it may have a direct vent system that vents the gases to the outside through a pipe. Make sure this pipe is clear and working. If you notice any clogs or damage, call in a professional for vent clearing and repair.

Replace an Old Furnace

Older furnaces are more likely to have problems that can lead to carbon monoxide leaks. If your furnace is more than 15 to 20 years old, you may want to think about replacing it with a new, more efficient model. Newer gas furnaces have built-in safety devices that are more complicated and are designed to run more efficiently , which means less chance of creating carbon monoxide .

We can help you select a high-efficiency gas furnace that meets your home’s heating needs and budget at BCRC Heating. With our professional installation services, you can rest assured your new furnace will run safely and efficiently for years to come.

Watch the Pilot Light

If your furnace has a pilot light, it’s important to pay attention to its colour. A healthy pilot light will shine blue. If you see a yellow or orange flame it may be because there is incomplete combustion and more carbon monoxide could be produced. If this is the case, switch off the furnace and call in a professional to make urgent repairs.

Recognize the Signs of Carbon Monoxide Poisoning

Finally, it’s good to be aware of the symptoms of carbon monoxide poisoning, especially during the winter months when your furnace is working hard. If you or anyone in your home experiences headaches, dizziness, nausea, shortness of breath or confusion, leave the house immediately and seek medical attention. Call emergency services to have your home checked for carbon monoxide leaks.
