Furnaces aren’t built to last forever. Most systems have a lifespan of 15 to 20 years, but warning signs often show up long before that. If your furnace is acting up as we close out the year, don’t ignore it—here’s what to look for:
Your Energy Bills Are Rising
Older or poorly performing units often have to work harder to produce the same amount of heat, which can spike your energy usage.
Frequent Repairs
If you’ve called your HVAC technician more than twice in the past year for furnace issues, you may be throwing money at a system that’s past its prime.
Uneven Heating
Some rooms too hot, others too cold? Your furnace may no longer be able to distribute heat effectively throughout your home.
Unusual Noises
Pops, rattles, or banging sounds coming from the furnace are often signs of internal component failure.
Your Furnace is Over 15 Years Old
Even if it’s still running, an older system will become less efficient and more prone to breakdowns over time.
Yellow Pilot Light
If your gas furnace has a yellow flame instead of blue, it may be producing carbon monoxide—a dangerous situation that calls for immediate professional attention.
Final Thoughts
Don’t wait for your furnace to fail on the coldest day of the year. If you’re noticing these warning signs, schedule a replacement consultation now so you’re ready for next winter.
