Can a dirty furnace become deadly? Think of it: a controlled fire starts every time your furnace comes on. When is the last time you had it checked? Most dangerous of all is something every furnace produces that you can’t see or smell.
While gas produces some Carbon Monoxide, it’s usually carried away through the furnace’s venting. A clean, efficient gas furnace produces very little carbon monoxide. Dirty ones, meanwhile, can produce deadly amounts of this colorless, odorless, deadly gas.
The older your furnace the more important annual safety checks become. Over time furnaces can develop small cracks in the combustion chamber. These cracks, not visible to the naked eye, can leak carbon monoxide into your home. That’s why we recommend annual safety checks.
Three warning signs of an inefficient furnace:
- Scale: flakes of us produced by the byproducts of burning gas. Over time it can damage your furnace.
- Chattering relays: A burner that huffs and puffs, banging, clunking is a sign of trouble.
- Yellow flame: A healthy flame is sharp and blue. A yellow flame means dirt is preventing your burner from mixing gas and air properly.
Keep your home warm and your family safe. Make sure an annual furnace safety check is part of your annual home improvement routine.
