Reddit Community Insights: Homeowners are divided on furnace maintenance. Some advocate for repairing until failure, while others suggest replacing at 15 years to prevent mid-winter breakdowns.
When to Repair: If your furnace is under 15 years old, operates efficiently, and repair costs are less than a third of a new unit, repairing is often more economical.
When to Replace: Signs such as frequent breakdowns, rising energy bills, uneven heating, or safety concerns (like a cracked heat exchanger) indicate it’s time for a replacement.
Expert Advice: Planning ahead and replacing before a furnace failure can save on costs and avoid emergencies.
Additional Considerations: Factors like the age of the furnace, repair costs, and energy efficiency should guide your decision.
You hop onto Reddit, type “should I replace my 15-year-old furnace?” and suddenly you’re scrolling through a thread full of strong opinions. One person insists, “run it until it dies!” while another swears they replaced it early and never looked back. So who’s right? As with most things in home maintenance, it depends. But the real trick is knowing what it depends on.
Let’s break down the Reddit chatter, sprinkle in Hahn’s professional perspective, and help you figure out whether to repair or replace before winter hits.
What Homeowners on Reddit Are Saying
Across multiple subreddits, homeowners tend to fall into three camps:
- The “ride it out” crowd – These folks argue that furnaces can run 20+ years, so why waste money early? They usually advocate for small repairs and regular filter changes until the system truly fails.
- The “replace before disaster” camp – They’ve lived through the nightmare of a January breakdown and aren’t doing it again. Their motto: replace when the unit hits 15 years old to avoid an emergency.
- The “depends on your bills” group – These homeowners base their decision on energy costs. If your furnace is running constantly or your gas bill keeps climbing, it may be time for a high-efficiency upgrade.
Reddit can be a surprisingly insightful place for real-world experiences, but every home and every furnace has its own story.
Hahn’s Expert Take: When Repairs Still Make Sense
At Hahn Plumbing, we’ve seen plenty of furnaces that still have life left in them. If your unit is under 15 years old and your repair costs are under roughly a third of a new system, repair is often the smarter move.
Here’s when repairing still makes sense:
- The heat output is consistent, and your home warms evenly.
- The system isn’t making new or worsening noises.
- Energy bills haven’t spiked significantly.
- Replacement parts are easy to find and affordable.
A minor repair, like a faulty ignitor, thermocouple, or sensor, can often extend your furnace’s life for years. For a deeper look at warning signs and simple prevention tips, see Hahn’s post: The Most Common Furnace Issues.
When It’s Time to Replace Instead
If your furnace is 15–20 years old, the balance starts to tip toward replacement. Here’s when our techs at Hahn start recommending a new system:
- Frequent repairs: If you’re calling for service multiple times a year, those costs add up fast.
- Uneven heating: Cold rooms, weak airflow, or short cycling can signal aging components.
- Loud operation: Rattling, booming, or screeching often points to failing blower motors or a compromised heat exchanger.
- Rising energy bills: Older units often run longer and harder to do the same job.
- Safety concerns: A cracked heat exchanger can leak carbon monoxide—a risk not worth taking.
A properly sized, modern furnace can deliver steadier comfort and lower ongoing costs. Planning before a mid-winter failure lets you compare options and schedule installation on your terms, not in crisis mode.
Smart Planning Beats Emergency Repairs
The best time to replace your furnace isn’t when it quits — it’s before it does. Schedule an inspection in early fall when technicians aren’t slammed with emergency calls. That gives you time to weigh repair vs. replacement, consider financing, and line up any supporting upgrades (like duct sealing or a smart thermostat) that improve performance.

The Bottom Line: Think Long-Term Comfort and Cost
If your furnace is 10–12 years old and showing only minor issues, repairs can still be a good investment. Once it crosses 15 years — or when repair costs creep past a sensible threshold — it’s time to think long-term. Whether you’re team “repair” or team “replace,” make the call before you’re shivering at midnight.
