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Outdated Technology Older furnaces lack modern features like programmable thermostats, zoning capabilities, and energy-saving settings.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

Dave was very pleasant to deal with and Twintech responded quickly when our furnace needed to be replaced ASAP. Installation was done on time and the crew were neat and tidy. We now have a great furnace that suits the needs of our family.

When your furnace kicks in over the holidays and you're not sure where to turn.. I'm so thankful that this company returned my phone call. I appreciated their transparency and clarity which allowed me to make an informed decision. With various quotes thrown at you, it can be difficult to make the right decision and trust the solutions offered by different companies. TwinTech spoke the truth and delivered on their word. Neat, timely and clean service; the peace of mind I needed during a very cold holiday season. I highly recommend them!

Pulling a old unit out and installing a modern heating system! Required drilling holes in the wall for the newer pipes. We went from 70% (I am willing to bet it was far less due to lack of maintenance and just old) to 96% newer . It now feels warmer and more pressure and we use to run extra heaters and feel as though they are not necessary!

I received three quotes before deciding to choose Twintech. Dave's prices was much more reasonable than the competitors. I most appreciated their honest recommendations. Others tried to oversell their products and services. Thank you Dave!

My 19 year old furnace stopped working when the cold weather hit in November, and I was left without heat. I interviewed several companies and found TWINTECH HEATING and COOLING to be very knowledgeable, quick to respond to my inquiries and very competitively priced.
Dave provided all of the information and pricing ahead of time and set up the appointment for the installation. Greg and Mitch arrived on time to do the installation and worked quickly and efficiently to complete the job.
After the completion of the installation, Dave followed up to ensure that everything was working well and that I didn't have any concerns.
Overall, this was a low-stress and flawless experience from start to finish. I would highly recommend TWINTECH HEATING and COOLING to anyone that requires a new furnace.

Our 20 year old furnace broke down during the first cold weekend this past November and our usual HVAC company never returned our phone call. Their loss, missing out on a sale since we didn't want to spend much fixing an old furnace and our 40 year old air conditioner was also long overdue for replacement. We proceeded in obtaining three different quotes for furnace and air conditioner replacement, and proceeded with the one we received from Twintech.
Dave was friendly, knowledgable and accommodating to our schedule and provided with us with a price that fell in the middle of the three quotes that we had. We felt that the Amana furnace and air conditioner he quoted us on were the best products and value offered to us and felt most comfortable with the professionalism and reputation of Twintech.
Greg, Grant and Mitch were at our house for installation the day after we decided to proceed. The guys were friendly and informative, the job was completed efficiently and workmanship appears excellent. Our house is certainly much more comfortable with the new two-stage variable speed Amana furnace compared to the old clunker! And, we're looking forward to enjoying the new air conditioner once summer rolls around again. Thanks Twintech!
