From northern Massachusetts to southern New Hampshire, most homeowners rely on their furnaces to weather our cold, snowy winters. These gas or oil furnaces and boilers require a dedicated flue to vent combustion gases effectively outside the home. A furnace flue liner protects this vital vent by serving as a critical safety barrier, preventing house fires and carbon monoxide poisoning.
An unlined or damaged furnace liner significantly increases the risk of a devastating fire and puts your family in danger of lethal carbon monoxide exposure. That’s why homeowners in northern Massachusetts and southern New Hampshire trust the experienced team at Sweepnman for expert furnace liner installations, relining, and maintenance.
Why Your Furnace Flue Needs a Liner
The furnace flue liner not only protects the surrounding masonry but also provides a smooth surface necessary for the efficient venting of toxic exhaust gases. It also insulates the furnace flue, increasing efficiency and lowering fuel costs. Without a functioning liner, the furnace's intense heat can ignite nearby combustible materials, starting a fire that can quickly spread throughout your house.
Types of Furnace Flue Liners
Furnace flue liners are available in a variety of materials. Sweepnman will recommend the best liner for your flue and heating appliance:
Clay Tile:
Often found in older masonry chimneys, clay tile liners are durable but prone to cracking under thermal stress and corrosive attack from combustion gases. As a result, they require more frequent repairs and eventual replacement. Sulfur dioxide and sulfuric acid are the byproducts of combustion mixed with rain/moisture that will naturally deteriorate brick and clay lining overtime causing them to crumble and cause potential blockages.
Stainless Steel:
The best and most versatile choice for modern furnace relining. Stainless steel is resistant to the acidic condensation produced by gas and oil heating systems, highly durable, and the flexible duct makes installation easy.
Signs Your Furnace Liner Needs An Inspection
Your furnace liner requires an annual inspection to check for damage and wear. Since cracks can occur at any time, contact Sweepnman immediately if you notice any of these warning signs:
- Rusted Flue Pipe: Visible rust, holes, or separated joints on the metal pipe that connects the furnace to the chimney.
- Sooty Buildup: Smelling soot or finding black residue near the furnace or in the basement.
- Pilot Light Failure: The pilot is difficult to light or keeps going out.
- Higher Fuel Costs: Your appliance is consuming more fuel than usual for the same amount of heat.
- Red Tag Notice: Your gas utility has disconnected your line due to a safety issue.
Furnace Liner Maintenance
Proper liner maintenance is key to minimizing repairs and preventing premature furnace failure. Maintain your flue liner with Sweepnman’s annual inspection and cleaning service:
- Annual Inspection: A certified sweep will perform a visual inspection annually to check the liner for damage, obstructions, or corrosion.
- Flue Cleaning: Even gas and oil flues can accumulate dust, debris, and animal nesting material. Periodic cleaning ensures a clear path for venting exhaust.
