Top 5 Signs You Need a New Furnace

Waking up to a freezing house? Not ideal. If your furnace is aging or acting up, now’s the time to pay attention—before winter really settles in.

Here are the top 5 signs your furnace might be ready for replacement—so you can act before you're left in the cold.

1. Your Furnace Is 15+ Years Old

Most furnaces have a lifespan of about 15 to 20 years. If yours is creeping up in age, it’s a good idea to start planning ahead. Even if it’s still working, older units tend to become less efficient and more prone to breakdowns, especially when cold weather hits.

2. Your Energy Bills Are Climbing

Have you noticed your heating bills creeping up each winter, even when your usage stays the same? As furnaces age, they lose efficiency, meaning they need more fuel to do the same job. A newer, high-efficiency system can make a noticeable difference in your monthly costs.

3. Uneven Heating Throughout the Home

If some rooms feel warm while others stay chilly, your furnace could be struggling to distribute heat evenly. This might be a sign of ductwork issues, but it could also mean your system isn’t powerful enough—or is wearing out.

4. Frequent Repairs or Breakdowns

One repair here and there isn’t unusual, but if you’re calling for service every year (or more), those repair bills can add up fast. At a certain point, it makes more financial sense to invest in a new system than to keep patching the old one.

5. Strange Noises or Odors

If your furnace has started making banging, rattling, or humming noises—or you smell something odd when it runs—it’s trying to tell you something. These could be signs of mechanical issues, cracks, or airflow problems that may require replacement rather than repair.
