Is My Furnace Too Old to Operate?
Posted On: December 20, 2024
Determining whether your furnace is too old to operate depends on several factors, including its age, efficiency, reliability, and safety.
Here’s how to assess whether it’s time to replace your furnace: 1.
Age of the Furnace Most furnaces have a lifespan of 15–20 years.
If your furnace is older than this, it might be time to consider a replacement.
Check the manufacturer’s label or consult your maintenance records to determine the age of your unit.
2.
Efficiency Older furnaces tend to operate at an Annual Fuel Utilization Efficiency (AFUE) rating of 60%–70%, meaning up to 40% of the fuel is wasted.
Modern furnaces have an AFUE rating of 90% or higher, saving you money on energy bills.
If your energy bills have been steadily increasing without a corresponding rise in usage, your furnace may be losing efficiency.
3.
Frequent Repairs If your furnace requires frequent repairs, especially for major components like the heat exchanger or blower motor, it may be more cost-effective to invest in a new system.
Rule of thumb: If repair costs exceed 50% of the cost of a new furnace, it’s time to replace.
4.
Inconsistent Heating Uneven temperatures throughout your home could indicate that your furnace is struggling to distribute heat effectively.
Older units often lose the ability to maintain consistent temperatures.
5.
Strange Noises or Smells Loud banging, rattling, or squealing noises may suggest worn-out parts.
Persistent odors, especially a burning smell, could be a sign of serious issues.
6.
Safety Concerns A cracked heat exchanger can leak carbon monoxide, a colorless, odorless gas that poses a serious health risk.
If you notice symptoms of carbon monoxide poisoning (e.
g.
, dizziness, nausea, headaches) or detect a gas smell, turn off your furnace and call a professional immediately.
7.
Outdated Technology Older furnaces lack modern features like programmable thermostats, zoning capabilities, and energy-saving settings.
Newer models often integrate with smart home systems for better control and comfort.
When to Replace:
If your furnace is nearing or beyond 15 years, has low efficiency, or is causing frequent issues, replacing it with a modern, energy-efficient model may be the best choice.
While upfront costs can be significant, long-term savings on energy bills and maintenance make it a worthwhile investment.

Reasonable price and the workmanship was prompt and timely and the employees were great to deal with.
May 2, 2020
The sales process was friendly, informative, and very consultative. They worked hard to earn our business by taking a careful look around our home to assess our needs, providing a lot of information about the product, and answering all our questions and finding the right solution for our home at a competitive price. They prepared us very well for what to expect on installation day, and the installation went very smoothly - no surprises, all very professional! They gave us a call after installation to ensure we were happy with the work. We're very happy that we chose to work with TwinTech to get our new furnace.

When our old oil furnace finally broke down we decided it was time to finally convert to natural gas and finally install central air conditioning at the same time. Knowing it was going to be a significant investment for us, we wanted to make the right choice. Twintech came highly recommended by a friend and we were not disappointed. From the first contact with the salesperson, until the final touches on the installation, we were so pleased with their service. Everyone from the company was so friendly, efficient and a pleasure to deal with. Best of all, the cost was very competitive. We would certainly recommend Twintech to anyone requiring HVAC work in their home.

Mitch from Twintech came out for our annual furnace inspection. We found him to be friendly, conscientious & he left the work area clean. We were also very impressed with the thoroughness of the job he did. This is the 2nd job weve had Twintech do for us & have been very happy with the results for each. We highly recommend this company. Thank you, Mitch, Dave & Greg.

Work was done on schedule, professionally, according to quote and with minimal inconvenience to building users. Very happy with the end result. The only area for improvement from my experience - need more timely quoting process.

The team was great! Very knowledgeable, professional and extremely helpful. A few days after install the unit didnt seem to be working, user error, but within minutes of contacting them..on a Saturday.. a tech was on the phone troubleshooting with us. I highly recommend Twintech for your cooling or heating needs. They stand by their products and a pleasure to deal with.

During the hottest week in the summer our old A/C decided to call it quits. I called Twintech Heating & Cooling after receiving a referral from a family member; came highly rated for being an honest, family-run business, who appreciates their customers. Dave was able to accommodate my hectic schedule and book a late evening appointment to walk through the specifics. Greg and Mitch arrived exactly on time a few days later, were very polite and friendly, and within a couple of hours had a new unit up and running. I also received a follow-up call to ensure we were happy with the Amana.
