A Dying Furnace – How To Tell?

Unlike most appliances that have an expiration date, furnaces don’t have one. The life expectancy of a furnace depends on a variety of factors. Knowing when your furnace is going to die is key because you will be able to evaluate all your options more thoroughly.

This can be avoided by performing routine maintenance. In the end, however, the furnace will reach the point when it cannot continue to run.

Always keep a close watch on your furnace if it’s beginning to struggle to keep a comfortable temperature. It is possible to catch many small problems early and avoid costly service repairs.

Symptoms of a Failing Furnace


The following warning signs are bad news for your furnace –

1. On & off cycling of the furnace

On and off cycles in a furnace are a sign that something is going on in the system. Furthermore, this is another frustrating indicator with many potential meanings.

2. Color of the burner flame

A dirty burner likely is to blame for a yellow flame, and the yellow color means gas is not fully burning. When the furnace is creating poisonous carbon, the flame may appear yellow or flicker.

  • Walls or other surfaces found to have excess moisture
  • From outside, rusted vent pipes can be seen
  • The chimney or vent is leaking water
  • Soot surrounding the furnace

The lifespan of an average furnace is about 15- 20 years. It may be time to install a new furnace depending on how old your furnace is.

5. Recurring service

Throughout the life of a furnace, it will need service and maintenance. Persistent problems, however, should be regarded as an indicator of larger problems.

6. Unusual noise

A furnace that’s weared out can produce unusual sounds like rattling or banging. There is a possibility that these sounds indicate damage. This issue requires immediate attention.

7. Continually adjusting the thermostat

The thermostat may not work properly, or your furnace might not be able to cope with the demand if your family constantly tries to find the perfect temperature by shifting the thermostat.

8. Building up moisture

An air that is stagnant or damp may indicate a problem with the vents, or perhaps even with the furnace. Condensation could indicate furnace problems, so keep an eye out for it.
