Your furnace is responsible for heating your home during the colder months, but when should a furnace be replaced? In this post, we take a look at five common warning signs.
The Age of Your Furnace
The average lifespan of a furnace is around 15-20 years. If you experience problems with a unit older than 18 years, it’s wise to consider replacing the furnace rather than repairing the issue. A unit at this age is likely on its last legs, and it will end up costing more to keep repairing it.
Energy Bills
Whether your furnace uses natural gas, oil or electricity, it accounts for a significant portion of utility costs – typically around 40%. If you notice an increase in energy bills that doesn’t correlate to increased use of your furnace, the unit might not be operating efficiently. Conversely, if you notice inconsistent temperatures, or that the unit is no longer heating your space efficiently despite consistent energy bills, you’ll want to have it inspected by an HVAC professional.
Noise
Although some measure of noise is normal for most HVAC equipment, if you notice your furnace starts making humming, popping or rattling noises, it could indicate imminent failure. It’s wise to have this issue inspected promptly.
The Presence of Soot
If you notice soot around air vents in your home, it’s an indication your furnace needs servicing, cleaning, repairs or replacement. This issue should be looked at immediately, as it poses a health risk in the form of a fire hazard and an increased risk of carbon monoxide poisoning.
Corrosion or Cracks
If you notice signs of corrosion or cracking around the outside of your furnace, have it inspected right away. These are signs of disintegration and should be taken care of promptly. Corrosion can lead to cracks in your unit, which in turn can allow gas to leak into your home.
When Should a Furnace Be Replaced? Conclusion
Having your furnace inspected, cleaned and maintained regularly can help prevent serious problems and keep you up to speed on the state of your furnace. The best time to have a furnace serviced is before the cold season. This avoids the headache of going without heat if your unit stops working in the middle of the winter and allows adequate time for repairs or replacement.
