Can a furnace explode? If your furnace starts to make noises or keeps shutting off, you might be concerned about the possibility of an explosion. The same is true of carbon monoxide leaks, but these are much less dangerous than explosions. But that doesn’t mean you should be alarmed. This article will discuss three common reasons that a furnace might blow up. These include improper installation, carbon monoxide leaks, and noise. Then, you can decide whether or not a gas furnace is right for your home.

Gas-burning furnaces are safer than electric space heaters

When choosing a space heater, you should consider getting a gas-burning furnace or an electric one. Both gas and electric space heaters produce carbon monoxide, which can be deadly and cause drowsiness and dizziness. Installing a carbon monoxide detector will help you avoid exposure to this dangerous gas. Also, both space heaters and furnaces require regular maintenance.

Improper installation

If your furnace is leaking fuel or you’ve noticed that it’s getting too hot in the house, you should get a technician in immediately. It may be possible that the problem isn’t as severe as you think, but if you notice a smell, you need to change the batteries immediately and call a professional. In either case, you need to evacuate your home. Improper installation can cause a furnace to explode.

Carbon monoxide leaks

If you’re wondering whether carbon monoxide leaks can cause a home furnace to explode, you’re not alone. Carbon monoxide is a colourless, odourless, toxic gas produced by burning gas. Since most furnaces exhaust these byproducts outdoors, you’re unlikely to smell the gas directly. However, if you do notice any soot stains or smells, you should get professional help.


There are many ways to avoid a furnace explosion, including having your system checked by a professional. Regular maintenance is critical to ensure that your furnace operates safely and efficiently. Check for a leaky carbon monoxide detector if you suspect your furnace might malfunction. Even if you do not imagine a furnace explosion, you should leave home immediately if you notice any suspicious activity. You should also ensure that your furnace’s gas line is intact.

Proper maintenance

While manufacturers design furnaces to meet strict safety standards, they can still explode if not maintained properly. Several signs of a possible explosion include a fuel odour inside the house. You should call a furnace technician for immediate repairs if you smell fuel. You should also avoid overloading the furnace with flammable solvents or other chemicals. These conditions can lead to component failure and a fire hazard.
