Today, standard furnaces are 80 percent efficient, while those with a rating of 90 percent or more are considered high-efficiency.
How do I know if my furnace is high efficiency?
Page Contents
If you are wondering what the efficiency of your current furnace is take a look at the sticker that has the model and serial number in it. The efficiency is typically included on the sticker that is on the face plate. If it is not then you can google the manufacturer and put the model number in.
How much more efficient is a new furnace?
And New Furnaces Are Indeed Much More Efficient
Older furnaces have an AFUE range of 56% to 70%, which means that between 30% and 44% of the natural gas goes to waste as heat bleeds from the combustion chamber and exhaust leaves the flue. New furnaces, however, can have AFUEs from 80% all the way to 98.5%.
Do I really need a high efficiency furnace?
One of the main benefits high-efficiency furnaces provide is cheaper energy bills. The high-efficiency rating means these heating systems use less gas to heat your home, potentially saving thousands on utility costs in the long run. Gas furnaces have a fuel utilization efficiency, AFUE, rating.
What is the difference between a high efficiency furnace and regular furnace?
What is the difference between high efficiency and standard efficiency furnaces? Standard-efficiency furnaces convert roughly 80% of the energy from gas into heat. High-efficiency furnaces convert 90-97% (depending on the model) of the energy from gas into heat. So basically: high-efficiency furnaces use less fuel.
What year did high efficiency furnaces come out?
Oh, there were some minor efficiency claims, but most were in the range of 60% to 70%. Then, sometime in the early 1980s Lennox came up with its high-efficiency “Pulse” furnace, which was probably one of the best-publicized new products in our industry since I can’t remember when.
Do furnaces become less efficient?
Typically speaking, a furnace can lose anywhere between 20% to 40% of its efficiency. This is because the parts in your furnace begin to wear down after years of use. This can be for many reasons, like heat, vibrations, and dust buildup.
Does a new furnace make a difference?
New furnaces vs. old furnaces: General differences
Furnaces today are able to heat your home much more evenly and efficiently than older furnaces. One way that they have been able to achieve these improvements is by blowing more air over the heat exchanger.
Do old furnaces use more gas?
Gas furnaces become less efficient as they get older, just like most air conditioners, heat pumps, and other HVAC systems.
How efficient are old furnaces?
Many furnaces that are 20 years old or younger operate at efficiencies at or above 70 percent efficiency. There is a quick and fairly accurate way for you to see how much money you might save each year on your heating bills. All you need to do is have the past 12 months of utility bills at hand.
Are high efficiency furnaces worth the extra cost?
Assuming your furnace is replaced after 15 years of use (what we recommend) you would get a total fuel savings of $1,318.05. A 90% furnace would save you $927.45 in fuel, compared to an 80% furnace. You can see how a high-efficiency furnace may end up being worth the extra money it costs you at the time of purchase.
How efficient is a 20 year old furnace?
20-year-old furnaces have an annual fuel utilization efficiency, or AFUE, of 78% or less, according to the U.S. Department of Energy. AFUE is the basic energy efficiency rating system used in the HVAC industry.
Is an 80% efficient furnace good?
A single-stage 80% or 95% furnace is less efficient than a two-stage furnace since the blower operates on this one speed and it’s high speed. A two-stage furnace has two speeds—high and slower. The slower speed is typically running at 65% furnace capacity.

Is a 96 furnace worth the extra money?
A 96% AFUE gas furnace is top of the line, powerful, and efficient. In fact, a 96% AFUE gas furnace is one of the most efficient gas furnaces available. Not to mention that it is a highly effective tool to heat your home in even the coldest conditions.
Are 2 stage furnaces worth it?
The two-stage furnace is more efficient than the one-stage because it doesn’t release as much fuel into the heat exchanger when the home is only somewhat cold. If it’s 5 to 10 degrees outside, a two-stage furnace will run in the partially-open position and only use 70% of the energy it normally would.
What is better a 1 stage or 2 stage furnace?
The ability to switch between two power modes makes two-stage furnaces more energy-efficient than their single-stage counterparts. The low power mode allows the unit to conserve energy as well as reduce temperature fluctuations and uneven heating in your home.
How much will I save with a two stage furnace?
The DOE test procedure shows fuel savings of 3.4% for two-stage furnaces relative to single-stage furnaces at the same AFUE, while the 2006 ASHRAE test procedure shows only a 0.4% decrease in fuel consumption.
Are 2 stage furnaces quieter?
A two stage furnace is quieter and generates more even heat through the house. The longer, slower heating cycle eliminates the kind of rapid warming that many people find uncomfortable from a single stage furnace.
What brand of furnace is the quietest?
Lennox SLP98V
With an efficiency rating of up to 98.7 percent AFUE, the SLP98V is considered as the quietest, most efficient furnace available on the market today.
Is variable speed furnace worth it?
The best news … a variable speed furnace motor is 80–85% more efficient than a standard furnace motor. So, if you are going to upgrade from a 90% to a 96% efficient furnace make sure it has a variable speed furnace motor, and you could enjoy energy savings of up to $400 a year. Otherwise it’s not worth the investment.
Will a new furnace be quieter?
Your New System Works Correctly
The most likely reason why your new furnace is noisier than your old furnace is because your new furnace is more efficient than your old furnace. The sound that you are hearing could simply be more airflow.
Why is my furnace so loud all of a sudden?
There are a variety of problems that can cause your furnace to produce loud noises. Types of noises such as scraping, banging, whistling, and popping may be a sign of a loose part, cracked heat exchanger, or dirty gas burners.
Why is my new HVAC so loud?
If you hear rattling, bangs, or clanking inside your home’s indoor HVAC system, something may have been knocked loose or broken. Often, this means a part got loose inside the blower. The louder the rattle, the worse the situation. If the rattling is loud, turn off your HVAC system and contact an HVAC company.
Why is my new Trane furnace so loud?
Over time, the bearings in the blower motor wear out, causing the motor to become noisy. Some furnace motors can be lubricated—if your furnace motor can be lubricated, try lubricating it first. If lubricating the motor doesn’t solve the problem, or if your motor can’t be lubricated, replace the motor.
