When to Replace Your Furnace
Posted On: February 3, 2025
Replacing your furnace is a significant investment, but knowing when it's time can save you money and prevent unexpected breakdowns. Here are key signs that indicate it's time to replace your furnace:
1. Age of the Furnace
Most furnaces last between 15 to 20 years. If yours is approaching or exceeding this range, consider replacing it before it fails.
2. Rising Energy Bills
Older furnaces lose efficiency, leading to increased energy costs. If your heating bills keep rising despite regular maintenance, a newer, energy-efficient model could save you money.
3. Frequent Repairs
If you’re calling for repairs more than once or twice a year, replacement may be a more cost-effective solution. The 50% rule applies—if repair costs exceed half the price of a new unit, replacement is the better option.
4. Uneven Heating
Cold spots or inconsistent temperatures in different rooms suggest your furnace is struggling to distribute heat properly.
5. Strange Noises
Banging, rattling, or squealing sounds could indicate worn-out parts. While some noises can be fixed, persistent issues may signal the need for a new furnace.
6. Excessive Dust or Dry Air
Older furnaces may struggle with humidity control, leading to dry air, static electricity, or excessive dust in your home.
7. Yellow Burner Flame
A healthy furnace should have a blue flame. A yellow or flickering flame could indicate carbon monoxide issues, requiring immediate attention.
8. Frequent Cycling
If your furnace turns on and off frequently, it could be overworking due to inefficiency or a malfunction.
Should You Repair or Replace?
- If your furnace is under 10 years old, repairs might be sufficient.
- If it’s 15+ years old with ongoing issues, replacement is often the smarter investment.
- Energy-efficient furnaces can significantly reduce heating costs and improve home comfort.

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!!

Twintech Heating & Cooling installed my furnace in 2022 and in fall of 2023 installed my Panasonic Heat Pump. Greg and Mitch did a great job. Helped me through the rebate process. Super happy with the Heat Pump. Only used my furnace 5 times this winter. Energy bills lower, carbon emissions lower.Thank you Twintech. I recommend highly!

They've cleaned my furnace a couple of times and mentioned that the hot water tank standards were going to change soon so I decided to change mine out.
There were a few challenges during the process but the installers handled the problems without missing a stride! I now have really hot water again!

Highly recommend Twintech Heating company, we got honest and detailed information on what was needed to replace and install a new gas furnace. Bob and Greg made us feel comfortable withe process through their thorough explanation and knowledge of the right furnace for our needs. The professionalism and courteous friendly attitude towards the customer is what we liked the most as they treated us like family. So happy with our decision and new furnace we will be looking into get our rental water heater replaced and installed by Twintech team. We feel better having their knowledge on our side and will only trust them with any further maintenance of furnace.

Customer service and knowledge is priority in this industry, and Twintech has it. I've dealt with their team for maintenance and a furnace replacement. They're accommodating and make great recommendations, and came through at a great price over the big guys in the industry. They'll be my next call when I need service or maintenance.

I decided that the noises and age of the existing furnace which was old and not very efficient to replace it. Gave Greg a call and Grant and Greg got to work on it. Because of supply issues with the current heating type that would be an easier install Greg convinced me to change the location of the system and it would provide me better service for heat and efficiency. I had skeptical but went ahead anyway putting trust in Greg And Grant. Greg, Grant and Mitch came through and in 2 days had completely relocated my heating and A/C system. I can honestly say Greg was right my old house has been warmer and more evenly heated as it ever was. For anyone reading this rather long winded review can take my word for it, Twin Tech can take care of your needs.
