Is My Furnace Even Worth Fixing?
Posted On: November 18, 2024
Deciding whether your furnace is worth fixing depends on several factors, including its age, the cost of repairs, and how well it meets your heating needs. Here's a breakdown to help you make an informed decision:
1. Age of the Furnace
- Under 10 years: Most furnaces last 15–20 years with proper maintenance. If your furnace is less than 10 years old, repairs are often worthwhile, especially for minor issues.
- Over 15 years: As furnaces age, efficiency declines, and major repairs may not be cost-effective. Consider replacement if your unit is over 15 years old and needs costly repairs.
2. Cost of Repairs
- Minor repairs: Issues like a clogged filter, faulty thermostat, or worn-out igniter are relatively inexpensive to fix. These are usually worth addressing.
- Major repairs: If the cost of repairs exceeds 50% of the replacement cost, it’s usually better to invest in a new furnace.
3. Frequency of Repairs
- If you’re calling a technician multiple times a year, your furnace may be nearing the end of its life. Frequent breakdowns are a sign that replacement might be the better option.
4. Energy Efficiency
- Older furnaces are typically less energy-efficient. If you notice rising energy bills despite regular maintenance, upgrading to a modern, high-efficiency furnace could save you money in the long term.
5. Performance
- If your furnace struggles to heat your home evenly or cycles on and off frequently, repair may not resolve the underlying inefficiencies. In these cases, replacement might be the more reliable solution.
When to Replace Instead of Repair
- The furnace is over 15 years old.
- Repairs are frequent and costly.
- Energy bills are unusually high despite maintenance.
- You’re planning to stay in your home for the foreseeable future and can benefit from a newer, more efficient model.
When Repair Might Be Better
- The issue is minor and affordable to fix.
- Your furnace is relatively new and otherwise performs well.
- You're not ready to invest in a new system.
If you're still unsure, consult with a trusted HVAC professional. They can assess the condition of your furnace and help you weigh the costs and benefits of repair versus replacement.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!

Amazing experience with TwinTech Heating & Cooling! Their team was professional, knowledgeable, and efficient from start to finish. They installed my new furnace quickly and left everything spotless. The technicians took the time to explain everything and made sure I was comfortable with the system before they left. Great customer service and fair pricing. I highly recommend them for anyone needing HVAC services!

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. Ive used the company in the past for my furnace so I was happy when I recognized Greg at my front door. Hes great and the service is always top notch. Id highly recommend using twintech for honest, superior service in the Durham region. Thanks!

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!
