Just like your fireplace connects to a flue in the chimney, each solid and fossil fuel appliance has its own flue. Many New England homes, especially older residences, have one or more chimneys connected to multiple flues to vent their oil and gas-fueled appliances. During our long, chilly winters, cleaning these flues is essential to reduce fire, health, and safety hazards.
Keeping your oil and gas flue clean and free of obstructions is the best way to prevent a house fire and exposure to deadly carbon monoxide. That’s why homeowners throughout the North Shore and Merrimack Valley trust the professionals at Sweepnman for expert Oil and Gas Flue Cleaning. When servicing your boiler, furnace, or other heating appliance, we provide every home with our white-glove service—leaving it in the same condition we arrived.
Why Furnace & Boiler Flue Sweep & Inspection is Essential for Home Maintenance
Keeping your oil and gas flue clean and free of obstructions is the best way to prevent a house fire and exposure to deadly carbon monoxide. While wood-burning appliances produce flammable creosote, fossil fuel appliances produce other dangerous byproducts.
Oil Flue Sweep & Inspection
Oil-burning furnaces and boilers produce a highly acidic, corrosive soot. This flammable material can build up inside the flue, leading to several problems:
- Flue Obstruction: Soot buildup and falling debris can quickly obstruct the flue, trapping dangerous exhaust gases inside your living space. It is important to understand that this is a naturally occurring process; as your system runs, the byproduct acids slowly and inevitably disintegrate clay liners over time. Because this acid-driven decay happens to every clay liner regardless of maintenance, it eventually leads to internal collapses and blockages that compromise your home's safety.
- Fire Hazard: Soot is combustible. If the appliance backfires or overheats, the sooty buildup can ignite and breach the flue, allowing a fire to spread into your home.
- Corrosion: The acidic nature of oil can erode the flue liner and mortar joints, accelerate the deterioration of the chimney, and increase the risk of fire and carbon monoxide poisoning.
Gas Flue Cleaning
While natural gas and propane appliances burn cleaner than wood, they still require periodic cleaning to prevent:
- Carbon Monoxide: The most critical reason for gas flue cleaning is to protect your family’s health. Any blockage—from debris and animal nests to damage or soot—prevents the deadly, odorless gas carbon monoxide (CO) from venting. This blockage can cause gas to back up into your home, creating a silent, deadly risk.
- Obstructions: Modern high-efficiency gas appliances typically produce more condensation. This increase in moisture can accelerate the deterioration of the clay liner, potentially restricting exhaust venting.
