When winter is at its peak and temperatures plummet to below minus 20°C, Calgarian homeowners know their furnaces are working overtime. While furnaces are built to work hard to keep your home warm, issues can arise.
When your furnace starts making strange smells, it might cause concern. These smells can range from harmless to downright dangerous, so knowing what to do about them is important for maintaining your comfort and safety.
Let’s break down the most common furnace smells, their potential causes, how to address them, and who to call for furnace and duct repair.
When to Be Concerned: Dangerous Furnace Odours
Some furnace smells signal potentially hazardous issues. If you notice any of these, turn off your furnace immediately, leave your home, and contact a professional.
Smoke
A smoky smell might mean a blocked chimney or vent, causing smoke to circulate through your air ducts. If your smoke detector goes off or the smell is strong, evacuate your home and call for help right away.
Burning Rubber or Plastic
A burning smell could indicate your furnace is overheating, damaging internal components. Shut off your furnace immediately and have a technician inspect it for potential repairs.
Chemicals
A chemical smell resembling formaldehyde often points to a cracked heat exchanger, a serious issue that can lead to carbon monoxide leaks. Turn off the furnace, evacuate your home, and seek emergency repairs.
Rotten Eggs
This distinct odour is often a sign of a natural gas leak. Shut off your furnace, leave your home, and call your gas company and a furnace professional.
Less Worrisome Smells: Maintenance-Related Issues
While these smells are typically less urgent, they can still affect your furnace’s efficiency and your home’s air quality. Hire a professional to address them quickly to avoid bigger problems down the road.
Musty Odours
A musty smell could mean trapped moisture or mould in your furnace. If the smell persists, have your furnace cleaned and inspected.
Burnt Dust
After sitting idle, your furnace may burn off accumulated dust when it’s first turned on. This smell should disappear quickly. If it lingers, it could indicate another issue.
Burning Oil
A clogged furnace filter is often the culprit. Replace the filter; if the smell continues, it could mean an oil leak that needs professional attention.
Dirty Sock Syndrome
This odd smell is caused by bacteria buildup, often due to condensation. Cleaning the furnace and ducts and replacing filters usually resolve the issue.
Preventive Tips to Keep Your Furnace Smelling Fresh
- Replace Filters Regularly: Change your furnace filter every 1-3 months, depending on your household’s needs.
- Annual Maintenance: Schedule a professional furnace and duct cleaning service in Calgary before winter starts to catch potential issues early.
- Duct Cleaning: Clean your ducts every 3-5 years or sooner if you notice persistent odours or allergens.
- Upgrade Air Quality Solutions: Consider installing air purifiers or humidifiers to maintain cleaner, fresher air throughout your home.
Frequently Asked Questions About Furnace Smells
Why does my furnace smell like chemicals?
This often indicates a cracked heat exchanger. Turn off the furnace and contact a professional immediately, as this can lead to carbon monoxide exposure.
