How Long Should My Furnace Last?

Posted On: February 18, 2025

How Long Should My Furnace Last?

A well-maintained furnace typically lasts 15 to 20 years, though this can vary depending on factors like maintenance, usage, and the type of furnace. Here’s a breakdown of different furnace lifespans:


  • Gas Furnaces: 15–20 years
  • Electric Furnaces: 20–30 years
  • Oil Furnaces: 15–25 years

Factors That Affect Furnace Lifespan:

  1. Maintenance – Regular tune-ups and filter changes can extend its life.
  2. Usage – More frequent use shortens lifespan.
  3. Installation Quality – A properly installed furnace lasts longer.
  4. Brand & Model – Higher-quality units often have longer lifespans.
  5. Climate – Harsher winters mean more strain on the furnace.

Signs It’s Time to Replace Your Furnace:

  • Frequent breakdowns
  • Rising energy bills
  • Uneven heating
  • Strange noises or smells

by Aaron on Twintech Heating and Cooling

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!

by Robert Rogers on Twintech Heating and Cooling

Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.

by Robert Mizuno on Twintech Heating and Cooling

We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!

by Ruth on Twintech Heating and Cooling

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!

by Anna Chin on Twintech Heating and Cooling

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!

by Connor Agnew on Twintech Heating and Cooling

Great experience all around. Bob was sharp and easy to talk to, and Greg handled the installation perfectly. Would hire them again in a heartbeat.

by Trevor Owens on Twintech Heating and Cooling

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

by Nicole Alain on Twintech Heating and Cooling

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!!

by Courtney Parkes on Twintech Heating and Cooling

Just hired TwinTech Heating & Cooling to do an A/C Unit removal & reinstall to allow for landscaping access on the side of my house, and they were wonderful!
Bob, Greg & Mitch make a great team! Quick appointment times, super knowledgeable, expert troubleshooting capabilities & very customer service oriented.
I would highly recommend them for all of your HVAC needs! Great job guys!!
