  • Foul smells like burning or rotten eggs can point to gas leaks, broken components or debris burning up.
  • Changes in flame colors and patterns may mean issues with the pilot light, burner assembly, or ventilation system. Yellow flames or flickering can result in elevated levels of carbon monoxide.
  • Inefficient heating can point to clogged filters or blocked air vents.
  • Unexpected energy bill spikes without any shift in usage is another sign something is wrong.
  • Lack of routine maintenance increases the chances of a dangerous mishap.

Never ignore combustion smells or sooting in the house. It may signal an imminent explosion. In 2021, a household’s furnace exploded, destroying their home — this emphasizes how important it is to be watchful. Don’t let your furnace’s age deceive you, it may have more explosions than a Michael Bay movie.

Age of the Furnace and Maintenance History

Maintaining the Age and Service Records of Furnaces is Crucial for Avoiding Explosions.

Staying up-to-date on the age and maintenance history of furnaces is essential for the prevention of explosions. Let’s take a closer look:

Age of FurnaceMaintenance History
8-10 yearsAnnual Check-ups
11-15 yearsRegular Cleaning
Over 15 yearsMonthly Tune-Ups

Age and service records are key to detecting possible hazards that could lead to an explosion. Keeping track of the age and maintenance record of the furnace is important for noticing any unusual sounds or leaks coming from it. So, routine maintenance must be strictly adhered to.

A dangerous incident occurred in Michigan due to a faulty furnace that was not replaced in time. This delay caused an explosion resulting in two fatalities. Therefore, it’s critical to stick to scheduled maintenance – any deviation could be life-threatening.
