High-efficiency means lower utility bills, not just nickels and dimes either; the savings can be hundreds of dollars a year, especially if you use propane to heat your home. Many high-efficiency models also have advanced motors that use less electricity and are extremely quiet.
Most furnaces have the blower factory set to deliver proper airflow on a decent duct system. Having excessive noise is an indication that the ducts are already undersized (and or furnace oversized) and cutting the speed below factory will overheat the furnace.
Acceptable noise levels for a furnace typically range between 40 to 60 decibels. However, it's important to note that specific noise levels can vary depending on the type and model of the furnace, as well as its location within the home.
Yes, but that's only one benefit. High-efficiency means lower utility bills, not just nickels and dimes either; the savings can be hundreds of dollars a year, especially if you use propane to heat your home. Many high-efficiency models also have advanced motors that use less electricity and are extremely quiet.
Today's furnaces are not only more efficient and safer but also significantly quieter. Central to this development is their focus on sound management.
Quieter Operation
Two-stage furnaces are quieter than single-stage furnaces due to their slower operating speeds and ECMs. Single-stage furnaces produce loud noises when they turn on and off.
While high-efficiency furnaces with an AFUE of 96% or more cost between $2,000 and $6,000, standard-efficiency units with an AFUE of 80% to 89% are priced from $500 to $1,500. Upgrading to a high-efficiency furnace with a higher AFUE rating can lead to significant energy cost savings.
If you have recently purchased a new furnace and have found that it is louder than your previous one, you might worry that something is wrong with your unit. Rest assured, this is a common misconception. New models are often louder than old ones for a number of reasons.
A well-maintained, high-efficiency furnace, on the other hand, is usually able to last 20 to 30 years. As a result, scheduling an annual maintenance appointment with an experienced HVAC company in your area is one of the most effective ways to ensure your home's furnace stays efficient for as long as possible.
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.
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.
For example, the Lennox SLP98V Variable-Capacity Gas Furnace is at least 50 percent quieter than competitor's furnaces, making the SLP98V gas furnace the quietest furnace you can buy1. SilentComfort™ is achieved by utilizing variable-speed technology. In other words, this furnace has a high and low speed.

Will a high SEER AC unit be quieter than my current unit? In most cases, high SEER air conditioners run more quietly than lower SEER-rated ACs, especially if they have variable-speed compressors and less noisy fan motors.
A loud buzzing noise almost always indicates that your furnace is working hard to generate warm air. This may mean that its blower fans are extremely dirty or that the motor powering the furnace fans is beginning to fail.
On a normal day, your home's furnace might make a little noise as it starts up, when it's turning on, and then when it turns off. You can always expect to hear some noise from the furnace. The thing about this noise is that it should never be disruptive.
The duct silencers enable maintaining proper acoustic parameters in the rooms – even reducing noise in the rooms which require a high degree of acoustic comforts, such as e.g. sleeping rooms or reading rooms. The noise can be generated not only by the flow of air through the ducts.
Don't worry; older furnaces tend to make sounds and are generally noisier than newer heating systems. Even if your heater is on the older side, it shouldn't make too much noise so that it disrupts your daily activities.
Another great benefit of newer central air conditioners is that they are much quieter.
Your New System Works Correctly
The sound that you are hearing could simply be more airflow. The new blower motors that are put into the current furnace technology are much more effective than older blower motors and are made to push air through your house.
