If you live in Milford or the Greater Cincinnati area, your furnace works hard through long, cold winters. But just like any other appliance, furnaces don’t last forever. One of the most common questions we hear from homeowners is: “How long does a furnace last?”
The answer depends on the type of furnace you own, how well it’s maintained, and the climate here in Ohio. At Turner On Services, we want to help you understand the typical furnace lifespan, warning signs of trouble, and when it’s time to plan for a replacement.
Average Furnace Lifespan in Ohio
- Electric furnaces: 20–30 years (when well maintained)
- Gas furnaces: 15–20 years on average
- Oil furnaces: 15–25 years, though less common in our area
Because winters in Ohio can be harsh, many systems tend to wear down a little sooner than the national averages. If your furnace is already past the 15-year mark, it’s smart to start budgeting for a furnace replacement.
Factors That Affect Furnace Lifespan
Type of Furnace
Electric furnaces generally last longer because they have fewer moving parts. Gas furnaces, while efficient, burn fuel — which causes more wear over time.
Maintenance History
Annual furnace maintenance makes a huge difference. Homeowners who schedule regular tune-ups often extend their system’s life by five years or more.
Usage
In Milford and surrounding towns like Loveland, Goshen, and Batavia, furnaces run heavily through the winter. The more hours your system operates, the faster it ages.
Installation Quality
A properly sized, professionally installed furnace will run more efficiently and last longer than one that was rushed or undersized.
Signs Your Furnace May Be Near the End
- Furnace is 15+ years old
- Frequent and costly repairs
- Uneven heating throughout your home
- Unusual noises like banging, rattling, or humming
- Rising energy bills without changes in usage
- Yellow instead of blue burner flame (gas furnaces)
If you’re noticing any of these warning signs, it may be time to consider a furnace replacement estimate before your system fails in the middle of winter.
Repair or Replace?
Not sure if you should repair your furnace or replace it? A good rule of thumb is the 50% rule:
- If repair costs are more than 50% of the cost of a new system, replacement is usually the smarter choice.
Our team at Turner On Services can evaluate your system and give you honest guidance — whether that means scheduling a repair or planning a full replacement.
