What Lasts Longer – Gas Furnace or Heat Pump?

Both should last 15–20 years with proper maintenance. A well-maintained heat pump might last slightly longer (18–25 years) due to fewer moving parts under extreme stress.

But here's what matters more than the type: maintenance and proper installation.

Gas Furnace Lifespan

Typical Lifespan: 15–20 Years

Gas furnaces have fewer complex components than heat pumps. They operate only during heating season (roughly November–April in the Bay Area).

Common furnace problems over time:

• Years 1–10: Usually trouble-free
• Years 10–15: Minor repairs, occasional part replacements
• Years 15+: Heat exchanger cracks, blower motor failures, ignition problems

Heat Pump Lifespan

Typical Lifespan: 15–25 Years

Heat pumps do both heating and cooling with one unit, which can translate to longer life, but they work more hours annually.

The Real Factor: Installation and Maintenance

A poorly installed heat pump will die at 10 years, and a well-maintained furnace will last 25 years.

The Maintenance Secret

Here's what will actually make your system last:

1. Change filters every 1–3 months
2. Schedule professional maintenance annually
3. Address repairs promptly
4. Keep equipment accessible for service
5. Monitor performance and report changes

A furnace maintained this way will last 20+ years. A heat pump maintained this way will last 20–25 years.
