5 Furnace Smells That You Should Never Ignore

With Indianapolis winters having an average temperature below 46 degrees, there is no doubt that we rely on our furnaces. 

Sometimes furnaces produce concerning sounds, but what about concerning smells? Left unattended to, certain furnace smells could cause damage and expensive repairs. 

Keep reading to learn about 5 types of furnace smells that you should address right away.

1. Musty or Moldy Smells

When you start up your furnace after not using it in summer, you may encounter moldy furnace odors.

Oftentimes, if you smell mold, that means it's present nearby. You may have mold growing in the ductwork in your home. It's also possible that there is mold on the air conditioning coil above your furnace. 

Call a trusted furnace technician to perform an inspection. For your safety, the mold will need to get cleaned out of wherever it is found.

2. The Smell of Rotten Eggs

If you smell something like rotten eggs or sulfur coming from your furnace, turn off your furnace and call a technician right away.

A rotten egg smell usually indicates a gas leak. Fuel providers put odor-creating substances in natural gas to help detect gas leaks. If you end up smelling the odor, it is an indicator of a natural gas issue.

Gas leaks require immediate attention because they could cause explosions or fires. 

Your furnace could also be experiencing a failed heat exchanger. A failed heat exchanger can pump carbon monoxide (CO) gas into your home. Be sure to test for carbon monoxide as high levels of the gas are dangerous.

3. Smoke Odor

The smell of smoke coming from your furnace is usually the result of a blocked chimney. A blocked chimney forces the smoke to go through the ductwork. 

If the smell is strong, or if your smoke detector goes off, shut off your furnace right away. In the case of a sudden, strong smell, leave your house and call a professional immediately. 

4. Metallic Smells

If the electrical elements in your furnace get too hot, they may produce a hot metal smell. The same issue can also produce smells like burning oil, plastic, or rubber.  

Excessive furnace heat can damage metal and rubber components. Turn off your furnace and call a technician right away. This will reduce the risk of fire and prevent an automatic shutoff. 

5. Dusty Smells

You may experience a dusty smell after starting your furnace for the first time in a while. Usually, this is a normal smell, and it will go away after the dust in the system blows off. 

If for some reason the dusty odor doesn't go away, there could be an issue. Try changing the air filter. If the odor persists, call a professional for help.

Repair or Replace? 4 Key Benefits of Choosing Furnace Repair

The cold days are getting longer, the frost is lingering and winter is announcing itself. Your home should be a cozy recluse from the low temperatures outside. 

And is it? Or are you finding it impossible to get out of bed because it's so cold in your home? Maybe you're going outside just to get a bit of weak sunlight just to warm you up.

If that's the case, you might need to have your furnace serviced. While you might be tempted to completely replace it, these 3 benefits of choosing furnace repair will change your mind.

1. Lower Energy & Fuel Costs

If your furnace is not operating at peak performance, you not only have to deal with an icy house, but it uses a lot more energy. Your furnace will be working harder, for a longer time, to get the job done - and not even get it done well.

Calling in a furnace repair service will get your furnace back in tip-top shape, saving energy and most importantly, lowering the extortionate bills you've probably been receiving.

2. Improves Your Home Air Quality

Having good air quality in your home is important for your health and wellbeing. Your furnace collects all the debris, mold, dust, and pollen in your home and then blows it out into the air.

The filters need to be changed, which is a standard procedure in heating furnace repair procedures. In this way, you have better air quality and a smoother working system. Are you convinced yet?

3. Prevent Accidents & Risks

While most furnace problems are annoyingly loud yet harmless, some electrical issues can pose a huge risk that is not worth ignoring. Your furnace may be relatively new, therefore a complete replacement is necessary. The last thing you need to be worried about is carbon monoxide leaks, or in the worst case, an explosion in your home. 

And there's no reason to worry. A quick tune-up by professionals can give you peace of mind that you and your home are free from any danger of accidents. 

4. Optimum Indoor Heating

This may seem obvious - why else would you be getting your furnace repaired? But this is about more than just warming up your home.

By servicing your furnace you can ensure that the heating is strong and even, reaching all corners of your home. A repair works to improve airflow and temperature detection which means that you can kiss those annoying cold spots goodbye.
