Do you smell an odd scent coming from your furnace? Many homeowners experience furnace odors, but don’t realize the possible hazard. The professionals at Snyder Air Conditioning, Plumbing & Electric are here to help. Here’s what you should know about the most common furnace smells that you must not ignore.
Four furnace smells to pay attention to
While it’s a good idea to pay attention to any unusual odors coming from your furnace, there are four main ones to be aware of, as they may pose serious risks:
- A sulfur or rotten egg smell could indicate a gas leak, which is a serious health and safety risk.
- A burning plastic or electrical smell could indicate a malfunctioning or overheating furnace, which could result in a fire.
- A dusty or moldy smell could indicate a dirty or clogged air filter, which can negatively impact air quality and exacerbate respiratory issues.
- A metallic or burning oil smell could indicate a problem with the furnace’s oil burner, which could lead to dangerous carbon monoxide emissions.
Regular furnace maintenance and inspections can help detect and address any concerning smells or issues before they become major problems.
Rotten Egg Furnace Smell
The smell of rotten eggs isn’t exactly a pleasant one, but in the case of your furnace, it should make things relatively easy to identify. After all, you’ll be able to tell that your furnace is causing the problem – not another appliance in your home.
In most cases, the rotten egg smell coming from your furnace indicates that you have a gas leak. This is the case because most gas companies scent their gas with a discernible smell to let technicians and residents know that they could have a leak since gas is unscented on its own.
The problem with the rotten egg smell in your home is that it could cause an explosion or fire in your house since you have gas in the air. If you’re near the furnace, go ahead and turn it off as soon as possible and open up windows to allow clean air flow.
Next, you need to leave your home and call the gas company for service. They may need to turn your gas off before your furnace can be fixed since it’s dangerous to work in an area with a gas leak.
Electrical Furnace Smells or Metallic Furnace Smells
Electrical smells and metallic smells are generally pretty distinct for the average homeowner since they don’t occur too frequently. In some cases, these smells will be a bit like burning wires, though they generally have a slightly different odor.
Electrical smells coming from your furnace often indicate certain components on the inside are getting too hot. If electrical smells come with a furnace that randomly shuts itself off, it’s likely a protective mechanism that won’t allow the furnace to run anymore and you’ll need to call for service immediately to use it.
Mechanical smells in your furnace may also indicate that certain parts on the inside that are made of rubber or metal are actually burning due to old age and general wear and tear. These parts will need to be replaced, but this is generally a minor repair that won’t cost you too much money.
If you notice electrical smells or metallic smells coming from your furnace, you need to shut it off immediately and not continue running it, even if it’s cold outside and in your home. Call your service provider for a repair as soon as you can, and once the furnace has been fixed, monitor it closely for a day or two to make sure the smell is gone.
Dusty Burning Furnace Smells
The smell of burning dust inside your furnace is one of the most common odors you’ll come across. In fact, most homeowners who have a furnace problem report this smell at one point or another.
In most cases, the dusty burning smell coming from your furnace is not unusual. If you’re just turning it on for the first time, chances are the furnace is actually burning away any dirt and dust that accumulates inside. This is very normal and you will generally notice that the smell goes away within a few hours.
However, if the dusty burning smell from the furnace doesn’t dissipate quickly after turning your furnace on for the first time of the season, there are some things you can do on your own to try and fix it. The first is making sure the air filter in your furnace is clean and up to date. If you’re not sure, your best bet is to replace the air filter and make note of when you replaced it so you can do it as frequently as suggested by your furnace manufacturer or technician.
If time doesn’t get rid of the dusty burning smell and replacing your air filter doesn’t either, you need to make a call for service. It could be a serious problem with your unit or you could simply need a deep cleaning that you won’t be able to take care of on your own.

Dust Build-Up on Components

Inspect and replace furnace filters regularly to avoid these issues. Proper maintenance and cleaning of the furnace can help too. If you smell burning, turn off the heater and get professional help.
Regular maintenance and filter replacement can prevent issues and prolong furnace life.

How to Handle Burning Smell from Heaters
Burning smells from heaters can be worrying. Knowing how to deal with them is important. It stops potential damage and keeps your home safe. Here are our top tips on identifying and handling burning smells from heaters.
Allowing the Heater to Operate for Ten Minutes
Turn the heater on for ten minutes before switching it off. This helps to reduce the smell that comes from burning dust, hair, and other particles inside the unit when it’s not in use. Burning off this debris avoids the unpleasant odor when you switch it on again.
Regular maintenance is essential, like cleaning and changing filters to stop the build-up of debris and keep the heater working well. If the smell persists or gets worse, get a professional to inspect it. That way, you can prevent any potential fires or hazards.
Regularly Replace Air Filters
Replacing air filters in your HVAC system is a must. It helps maintain processing power and stops overheating. This can stop costly repairs or replacements. A clogged filter stops the airflow and reduces efficiency, meaning it works harder for longer. This puts strain on the system’s parts, reducing their lifespan.
Every three months, or more often if you have pets or allergies, replace the filter. This improves airflow and indoor air quality, as well as saving energy and money. Plus, filter replacements are affordable and easy to get. Not replacing the filter can lead to bad smells, like burning dust or hair, and potentially harmful pollutants and allergens in your home.
Set reminders to replace the air filter. This will keep your HVAC system running smoothly.
Cleaning the Heater and Ductwork
Regular cleaning of the heater and ductwork is crucial! Dust, debris and other contaminants can lead to health issues such as asthma, allergies and respiratory problems. A malfunctioning heating system can also emit burning smells, like burnt dust or plastic. So inspect and clean the furnace, air filters, vents and ducts.
DIY methods include vacuuming dust, cleaning filters and wiping down the furnace and ducts. But it’s best to hire a professional HVAC technician once a year. This ensures the heating system works efficiently, saves energy and provides clean, healthy air.
Pro tip: Use high-efficiency air filters and change them regularly to reduce dust and contaminants in the air.
Removing Foreign Objects from Vents or Ducts
It is essential to take out foreign objects from vents and ducts. These can include dirt, dust, debris and even small animals. If not removed, they can clog up the vents or ducts. This makes the HVAC system work harder and increases energy bills.
Turn off the HVAC system before getting started. Use a vacuum or brush to take out any debris blocking the vent or duct. If there are signs of damage or leaks, contact a professional HVAC technician from Snyder immediately.
Put in air filters and get regular maintenance for the HVAC system to stop foreign objects entering the vents or ducts.
Immediate Attention for Electrical Wiring Issues
Attention to electrical wiring must be immediate. This is because potential risks like electrical fires, shocks, and damage to electronics can arise. Signs of faulty wiring include flickering lights, circuit breakers that often trip, burning smells, and unworking outlets. It is important to take care of these issues quickly. Call a professional electrician from Snyder immediately if you have electrical problems. Not taking care of electrical wiring could lead to serious issues, not just for your home, but also for you and your property.
Having a professional from Snyder inspect and maintain your home’s electrical system can help prevent these issues. Pro tip: Get a fire extinguisher and smoke detectors for extra safety.
