Your furnace may still heat your home just fine—but that doesn’t always mean it’s performing efficiently or safely. Sometimes, “working” isn’t the same as working well. Here’s when it may be smarter to replace your furnace instead of repairing it.
- It’s Nearing the End of Its Lifespan
Most furnaces last 15–20 years, even with regular HVAC maintenance. After that, components wear out, efficiency drops, and reliability decreases.
If your system is over 15 years old, even if it’s still heating, it might be time to consider a furnace replacement—especially before winter hits Northern Utah.
- High Operating Costs
Older furnaces, especially single-stage models, burn more gas and cycle on and off more often. This means:
- Higher energy bills
- Uneven heating
- More frequent service calls
A new high-efficiency furnace can save significantly on utility costs while providing more even, reliable heat throughout your home.
- Safety Concerns: Cracked Heat Exchangers
A cracked heat exchanger is one of the most serious issues in older systems. It can leak carbon monoxide, a colorless, odorless gas that’s extremely dangerous.
The American Gas Association recommends shutting down any furnace with a cracked exchanger immediately. In most cases, replacing the unit is safer and more cost-effective than repairing it.
- Frequent Repairs or Hard-to-Find Parts
If you’ve had to call for furnace repair more than once this season—or if your technician says parts are getting scarce—it’s likely time for a new system installation.
Paying for major repairs on a 15+ year-old furnace is often money that’s better put toward a modern, energy-efficient upgrade.
Bottom Line
A furnace that “still heats fine” isn’t always fine. Age, efficiency, and safety matter just as much as whether it turns on.
Upgrading to a new high-efficiency furnace can reduce energy use, improve comfort, and keep your family safe through Utah’s cold winters.
