The more efficiently the furnace burns, the higher the AFUE. The higher the AFUE, the less money you have to spend to keep your house cozy all winter long. Which is definitely a good thing. And, FYI, a 96% AFUE gas furnace is about the best you can find.
A furnace with an AFUE rating of 95% will require significantly less fuel (natural gas) to heat your home than a unit with an 80% AFUE rating. While higher-efficiency furnaces tend to cost more upfront, they allow homeowners to save money on heating costs every year.
If a furnace is rated at 80 AFUE, that means it will waste 20 cents of each dollar you spend on heating. In contrast, a 96 AFUE furnace will only waste 4 cents. That might not sound like a huge difference, but it adds up over the winter. And it'll add up over your furnace's lifetime, which is typically 15–20 years.
Are the fuel and other savings from installing a high efficiency system worth the extra cost? In short, yes, but let's look at the facts. Fuel savings: Going from a 70 AFUE old unit to a 90 will instantly give you a 14% savings on fuel usage. Go to 95 AFUE, and you'll net a nice 18%.
In our expert opinion, if you are planning to live in your home for 5+ years, the 95% furnace is the clear winner, as you may already recoup savings in energy costs within the first 3-5 years of operation that offset a higher purchase price.

The overall total limit for an efficiency tax credit in one year is $3,200. This breaks down to a total limit of $1,200 for any combination of home envelope improvements (windows/doors/skylights, insulation, electrical) plus furnaces, boilers and central air conditioners.
Understanding Total Costs
Gas Furnace: $3,000 – $6,000. Electric Furnace: $2,500 – $5,000. Oil Furnace: $4,000 – $8,000.
Usually, it is a quick fix, but sometimes the failure can be caused by a much bigger problem. The most expensive part of an AC unit to replace and repair is the air compressor.
Even a slightly undersized furnace will accomplish the job the majority of the time. Taking things down a few sizes will more than likely solve some of your common heating problems like too high of a utility bill while half of your house is blazing and the other half is an icebox.
Cost Comparison: 80% AFUE vs.
In general you should expect to pay between $1,500 and $4,000 for the furnace alone, not including installation, and a furnace with an AFUE rating of 96 percent will likely cost you 40-50 percent more than one with an AFUE rating of 80 percent.
Long-term savings on energy costs.
Two-stage furnaces cost more to purchase and install than traditional models. But factoring in their 20-25 percent fuel efficiency advantage, and assuming a normal lifespan of about 20 years, the extra cost will be more than erased by the cumulative energy savings.
Replacing a 20-year-old gas furnace is typically a wise investment. In a country with diverse climates and heating needs, the benefits of a modern, energy-efficient furnace are manifold.
Of course, you will see the greatest gains if you are going from a low-efficiency furnace to a high-efficiency furnace. In this case you can expect to see as much as 20-25% savings on your heating bill. If you are replacing a medium-efficiency furnace, the gains will be smaller.
Your base homeowners policy will cover many types of damage to your furnace. An extra endorsement known as Equipment Breakdown Coverage (EBC) will give you additional coverage for certain types of mechanical or electrical failure.
Better pricing: Since there's less demand for HVAC system replacement in spring and fall, your HVAC contractor might even offer their own savings incentives.
Labor: Typical labor costs can range from $50 - $100 per hour for a licensed technician. Each additional team member will be an additional charge. Depending upon the complexity of the job, a new furnace installation can take 10-15 hours!
Known as the Energy Efficient Home Improvement Tax Credit, this program allows you to earn a tax credit of up to $3,200 a year. The program started on January 1, 2023, and will run until December 31, 2032, which means you may be eligible if you upgrade or replace any HVAC unit within the next decade.
Gas-Fired Furnaces
Individuals who purchase and place into service qualifying equipment between January 1, 2024, and December 31, 2024 may qualify for a non-refundable tax credit of up to $600 per system, subject to an annual limit of $1200 per taxpayer.
How to claim the Energy Efficient Home Improvement Credit. File Form 5695, Residential Energy Credits Part II, with your tax return to claim the credit. You must claim the credit for the tax year when the property is installed, not merely purchased.
A gas furnace with a 96% AFUE (Annual Fuel Utilization Efficiency) rating is a highly efficient type of gas furnace that can help to save money on heating costs and reduce the environmental impact of heating a home or building.
The same amount of money is spent on that fuel being used. But, in one scenario 80% of the fuel is used to contribute to delivering heat, whereas in the other scenario 95% of the fuel is used to contribute to delivering heat. So, with the higher efficiency furnace model, fuel is better utilized and less is wasted.
Lower Energy Bills and Cost Savings: Upgrading to a higher AFUE furnace can result in significant savings on your energy bills. The increased efficiency means that more of the fuel is converted into heat, reducing the amount of wasted energy and lowering overall heating costs.
