Should You Repair or Replace Your Furnace?
Furnaces don’t last forever, and over time they may need repairs or even full replacement. But how do you know when it’s time to stop fixing your old system and start fresh with a new one? If your furnace keeps breaking down or the repairs are getting expensive, it might be smarter to get a new one. A new high efficiency furnace can save you money in the long run by lowering your energy bills.
Here are some key signs to help you decide if it’s time to repair or replace your furnace.
1. Your Furnace Is Over 15 Years Old
Most furnaces last between 15 to 20 years, especially if they’ve been well cared for. If your furnace is older than 15 years and the repairs cost more than one-third of what a new system would cost, replacement is usually the better choice.
- If the unit hasn’t been maintained well or was poorly installed, it may need to be replaced earlier.
- On the other hand, a well-maintained furnace could last longer than expected.
Ask a licensed HVAC technician for an honest inspection. They can help you figure out if repair or replacement makes more sense for your situation.
2. Your Heating Bills Keep Going Up
Have you noticed your energy bills getting higher every winter? That’s a common sign your furnace isn’t working efficiently.
Older furnaces lose efficiency over time. They use more energy to do the same job, which means you’re paying more for less heat.
Newer furnaces, especially gas furnaces with modulating valves, use much less energy. They may cost more upfront, but they save you money over time. Check with your local utility company—they may offer rebates or incentives if you install a high-efficiency system.
3. Your Furnace Needs Frequent or Expensive Repairs
If your furnace has had a major breakdown or several smaller ones, it may be time for a furnace replacement—especially if the warranty has expired.
Even if it still runs, an older furnace may be using more energy and wearing out inside. Watch for signs like:
- Strange sounds (popping, rattling, buzzing)
- Parts needing constant replacement
- Big repair bills
It’s important to do a cost-benefit check. If repairs are close to the cost of a new system, replacing may be the better deal.
4. Your Home Feels Uneven or Uncomfortable
Is your house warm in one room but cold in another? Do you keep adjusting the thermostat? These are signs your furnace isn’t heating your home properly.
You may also notice:
- Muggy air
- Weak airflow
- The furnace running constantly without warming the space
This could mean the system is too old or not working like it used to. Before winter hits, have a furnace maintenance visit scheduled in the fall to check for issues. Also, don’t forget to check your filter monthly—a dirty filter can hurt airflow and air quality.
5. Safety Should Always Come First
Some furnace problems are more than just comfort issues—they can be dangerous. A cracked heat exchanger can leak carbon monoxide into your home, which is very serious.
Look for warning signs like:
- A yellow furnace flame instead of blue
- Soot around the furnace
- Excess moisture on windows or walls
- Headaches or nausea
If you notice any of these, turn off your furnace and call your utility company or a licensed HVAC professional right away. If there’s a safety concern, replace the furnace immediately.
