What is a Furnace Puff Back and How to Prevent One?
WHAT IS A FURNACE PUFF BACK?
A puff back is a sudden explosion of unburned oil in the combustion chamber of a furnace, water heater, or boiler. When this happens, it sends soot and smoke throughout your home or business, coating walls, ceilings, furniture, and other surfaces. Not only does it damage your HVAC system, but it also leads to costly cleanup and restoration.
WHAT CAUSES A PUFF BACK?
Puff backs often result from oil buildup due to leaky pipes or improperly functioning burners. When the next heating cycle begins, the collected oil ignites, creating a small explosion. Poor maintenance, faulty shutdown sequences, or debris in the fuel vent can also trigger a puff back.
HOW TO PREVENT A PUFF BACK
1. Schedule Annual Furnace Maintenance
Have your furnace professionally inspected and cleaned at least once a year. A qualified technician will check all components, clean the burner, and ensure everything is working correctly.
2. Watch for Warning Signs
Strange odours, unusual noises, or visible soot around your furnace should never be ignored. If you notice rumbling sounds or strong smells, call a technician immediately.
3. Check for Leaks and Debris
Regularly inspect the furnace and piping system for oil or air leaks. Dirt or discoloration around fittings may signal a problem. Also, check the fuel vent connector for any blockages or debris.
WHAT TO DO IF A PUFF BACK OCCURS
If a puff back happens, act quickly. Smoke and soot are corrosive and can seep deep into walls and materials, making stains and odours harder to remove over time.
Don’t try to clean it yourself. Professional cleanup is essential to fully restore your property and remove harmful residues.
