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Outdated Technology Older furnaces lack modern features like programmable thermostats, zoning capabilities, and energy-saving settings.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.

Great sales member named Dave came in told us some amazing items and how they would be priced installed an all. We couldnt believe it! The next day the ac was installed, that day one employee named Greg told us that our furnace was working way to hard and was causing us to use way too much gas. So two days later they came in an installed a new furnace!

They removed and discarded old furnace. Installed new furnace. Installed air intake pipe, that had never been installed by builder, no charge. Replaced loose hose on floor with hard pipe and rerouted it to drain, no charge. Almost 33% cheaper then quote from Enercare, which was the company we dealt with and had insurance with for 8 years. No yearly fee for cleaning/insurance, saves 300 a year. Courteous, professional, fast, and friendly. My wife and I have been recommending them to everyone we know and meet, and will continue to do so. Thanks for everything, Twintech!!!

Finally! An honest company with highly knowledgeable and informative staff. Had a furnace service and found multiply errors in our system from an amateur installer. Very fair price to correct problems and will definitely use again.

During the summer, I previously hired TwinTech to replace my air conditioner when it failed. They did an excellent job so when I decided to proactively replace the furnace I contacted them. The furnace I had was 22 years old and showed signs of internal leakage. It still worked but rather than wait to have it fail in cold weather, I decided to purchase a higher efficiency model before it failed and take advantage of energy efficiency rebates. TwinTech offered very useful advice on the make and model of furnace to choose including high efficiency and variable speed motor. The price was reasonable, TwinTech arrived at the allotted time, installed the new furnace (including some re-routing of exhaust lines since the existing ones were too close to other vents), removed the old furnace, tested the installation and cleaned everything up. Overall, it was a good experience, they did a great job and the new furnace is working well.
