Can a dirty furnace become a deadly furnace? 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 very gas furnace 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.
