When Would My Furnace Need Replacing?

Posted On: September 26, 2024

When Would My Furnace Need Replacing?

There are several signs that indicate it may be time to replace your furnace. Here are a few key factors to consider:


1. Age of the Furnace

Most furnaces have a lifespan of 15 to 20 years. If your furnace is approaching or exceeding this age, it’s likely time to consider a replacement, even if it’s still running, as its efficiency may have declined.


2. Increased Energy Bills

A sudden rise in your heating bills without a corresponding increase in usage could indicate that your furnace is losing efficiency. Older units have to work harder to maintain the same temperature, costing you more in the long run.


3. Frequent Repairs

If your furnace requires frequent repairs and maintenance, especially for major components like the blower motor or heat exchanger, it may be more cost-effective to replace it instead of continuing to pour money into fixes.


4. Inconsistent Heating

If your furnace struggles to maintain a consistent temperature throughout your home or if you notice cold spots, this may indicate that it is no longer able to properly distribute heat.


5. Strange Noises

Rattling, banging, or humming noises coming from your furnace can signal internal issues, such as loose or failing components. These issues may worsen over time and could lead to a complete breakdown.


6. Yellow Burner Flame

The burner flame in a properly functioning furnace should be blue. A yellow flame can indicate incomplete combustion, which may be a sign of carbon monoxide production—a serious safety risk.


7. Dry or Dusty Air

Older furnaces can lose the ability to properly humidify the air, leading to dry skin, irritated respiratory systems, and an excess of dust in your home. A new unit can improve air quality.


8. Obsolete Technology

Furnaces have seen technological advancements, such as energy-efficient models with higher AFUE (Annual Fuel Utilization Efficiency) ratings. Upgrading to a modern furnace could save on energy costs and reduce environmental impact.


9. Rising Repair Costs

When repair costs approach 50% of the cost of a new furnace, it's often better to invest in a replacement.


Keeping an eye on these factors will help you know when it's time to replace your furnace before a complete failure occurs, ensuring your home stays warm and efficient.

by Private User on Twintech Heating and Cooling

Great service and great people to deal with, from sales to installer. I highly recommend this company.

by GR from Oshawa on Twintech Heating and Cooling

Twintech replaced our aging furnace and air conditioner recently. I highly recommend this company. Their quote was competitive, they were on time and respectful of our home and extremely professional. From the salesman to the installers and the owner who followed up afterward to ensure we were satisfied, we are very pleased with the service. We are looking forward to working with this company for all of our HVAC needs for the years to come. Excellent workmanship and service!

by nathans in Scarborough on Twintech Heating and Cooling

We wanted to get our AC replaced as it was 22-years old and added to this our furnace was costing more and more to repair. So, we decided to get both the furnace and AC replaced.

After going through a few quotes and product reviews we decided to go with Twintech. The three-men crew arrived early in the morning, wasted no time and got to work right away. By 2:00 pm, they were all done. I’ve found their work to be top notch and they were completely professional. I had all my questions answered to my satisfaction both during the progress of their work and at end.

I have pleasure in recommending Twintech to anyone who is looking to get their furnace or Ac replaced

Our air conditioner died On a Saturday and within hours Dave came out to take a look and discuss replacement/repair options.
The new air conditioner was installed on the Wednesday. The new unit was installed quickly. The installers were friendly and cleaned up afterwards.
We noticed a slight leak around the furnace that night and they came out the next day and fixed the issue. It has been working great and is quieter than our previous unit.
Very satisfied and would highly recommend TwinTech.

I contacted TwinTech to replace my 20-year old A/C. Dave, their service rep, promptly replied and was at my home within 2 hours. He was friendly and knowledgeable and didn't try to upgrade or oversell their A/C units but suggested the best fit for my small 1000 feet bungalow. Although this was during a heatwave and very busy, they were able to fit me in 2 days later. The TwinTech crew installed a 1.5 ton Ducane A/C unit that is now running smoothly while maintaining a constant cooling temperature. The crew were very courteous, professional and efficient and I will definitely recommend TwinTech to family and friends. I much appreciated your great service.

We had a great experience. The guys who installed our a/c did a nice job. Cleaned up.

by Private User on Twintech Heating and Cooling

excellent crew, fast and efficient! Would call them again when I need a new furnace.

by Private User on Twintech Heating and Cooling

Professional, courteous and efficient, don’t need to say more than that! Use them you will not regret it.

by Private User on Twintech Heating and Cooling

TwinTech was a pleasure to deal with from the estimate through installation. We replaced a 28 year old a/c unit with one recommended by TwinTech's sales representative Dave who took the time to go over the product with us and answer any questions. The warranty is for 10 years parts and labour and they will complete the registration for you. Installation was by Greg (owner) and Mitch and Spencer who were quick and efficient and left everything clean and tidy.

by Private User on Twintech Heating and Cooling

Very professional, from the sales consultation and inspection to the final installation. Met every expectations we had for the job. A local business with great client support. We highly recommend. Twintech is a blue chip! Thanks!

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.

by Linda on Twintech Heating and Cooling

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!
