Purchasing a new furnace may not be a priority right away. But it’s wise to know the things that will likely influence your choice when you’re ready to buy. Here are seven things you’ll want to think about when you're due for furnace replacement in Sharonville.
1. Size and Installation Quality
To run at maximum efficiency and comfort, your furnace must be properly sized for your home. When it comes to furnaces, bigger is certainly not better. We frequently get requests from customers to install a big furnace in the misguided belief that a larger furnace is either more reliable or will offer better comfort.
The opposite is true. Large furnaces will short cycle, or continuously turn on and off. This leaves you uncomfortable, with more expensive energy bills and a furnace that could wear out much sooner.
This is why it’s crucial to work with the right company when purchasing a new furnace. Even if it’s the correct size but installed wrong, the U.S. Department of Energy says you could forfeit as much as 30% of your energy efficiency.
Another crucial component of installation is ductwork. If yours is old or designed wrong, you might have problems with noise or comfort. A furnace is only as good as the duct system it’s attached to.

2. Energy Efficiency
Furnaces are ranked by a term known as AFUE, or annual fuel utilization efficiency. Like miles per gallon on cars, this rates the annual gas consumption of a furnace. The greater the number, the less gas is wasted during the heating process.
If your current furnace is 15 years old, it’s likely rated well below 80 AFUE. As an example, if your HVAC system is 70 AFUE, you’re throwing away up to 30 cents of each dollar you spend on heating.
Here’s how AFUE ratings work today:
- 80 AFUE—minimum efficiency rating in the U.S. and Canada.
- 90 AFUE—ENERGY STAR® rating for furnaces in the U.S. South.
- 95 AFUE—ENERGY STAR® rating for furnaces in the U.S. North and Canada.
- 98 AFUE—best efficiency rating available.
3. Blower Motor Technology
As you research new furnaces there is one more important thing to consider: blower technology. This part circulates air throughout your home. And it also consumes a lot of electricity, so it’s essential to be familiar with your options.
There are three kinds of blowers available on furnaces today. They include:
- Standard blower motor. Furnaces that aren’t ENERGY STAR rated have a traditional blower motor that’s been mostly unchanged for the past 30 years. This motor is the least expensive and also the least energy efficient.
- Constant torque motor. This technology finds a balance between price and energy efficiency. It provides an electrical efficiency boost over a traditional motor design.
- Variable-speed motor. The most energy-efficient furnaces can run at different speeds. Instead of running at full blast 24/7, they will quietly operate at a low or medium speed at times. This helps enhance your comfort while keeping energy costs down, both in the winter and summer. And it also keeps indoor humidity under control.
4. Sound Reduction Technology
Sound has become a very significant consideration with furnace installation, so another dramatic improvement has been noise management. Some of these features include:
- Sealed and insulated cabinets
- Variable-speed blower technology
- Whisper-quiet gas burners
With this technology, you might not even notice that your furnace is running.
5. Smart Thermostat
You probably use a programmable thermostat, but it's quite possible you probably aren’t making the most of your energy savings. These thermostats can be complicated to program, especially if your schedule changes from day to day.
A smart thermostat removes all the guessing about energy efficiency. Many models can pick up on your temperature preferences and then produce an energy-saving schedule to match. They also recognize when you’re home or away and will adjust your heating and cooling as needed.
As an extra perk, you’ll also be able to keep tabs on and change your settings from just about anywhere on your phone. Some models can even alert you if they detect a problem with your furnace or remind you when it’s time to change your air filter.
There’s a significant difference in furnace quality and reliability. Like any big purchase, we think it’s wisest to go with a major brand name. With a top brand like Lennox® or Goodman®, you’ll have more confidence in the technology and that the manufacturer will uphold its product warranty over the long haul.
Furnaces typically have two main warranty coverage areas:
- Heat exchanger. This is the center of the furnace and the most expensive component to replace. This part typically has a 20-year limited warranty or lifetime limited warranty, but this can differ based on the manufacturer and furnace model.
- Main parts. This includes the blower motor, electronic controls, ignitors and other key parts. Warranties can range from as little as a one-year limited warranty to as long as a 10-year limited warranty.
When going over warranty coverage, it’s essential to know it's limited. So, you should make sure you get the restrictions. For instance, nearly all standard manufacturer warranties only cover the cost of the replacement part, not labor. And labor on a replacing heat exchanger could get very expensive.
Once your new furnace is running, make sure you finish the product registration right away. Many manufacturers may limit the warranty term if the product registration is not completed. This step is easy and typically only takes a few minutes.
How much does all this cost anyhow? It could vary from $1,700 for a basic furnace, or $5,500 or more for a high-efficiency system.
As you consider these costs and the impact to your budget, keep in mind that unlike nearly every other appliance you may need to purchase, your new furnace may help pay for itself from the monthly energy savings it provides.
A couple of other ways to save include:
- Getting a new air conditioner simultaneously.
- Purchasing at the right time, such as in early fall, mid-winter and early spring. You may be able to get additional discounts and rebates during this slower season.
- Take advantage of rebates from the federal and state government, as well as from your local utility provider. We can help you navigate this process.
- Finance your new furnace or enroll in our exclusive HVAC Advantage Program™. For just one low monthly fee, you’ll get a new furnace with repairs and maintenance included.*
How Do I Know When to Replace My Furnace?
Now that you know what to search for in a new furnace, when should you replace your outdated one? Here are a few tips from our Experts that will help you decide.
Heating systems usually last 15–20 years. How long yours will last depends on whether you’ve done furnace maintenance, where you live and your temperature preferences. If you’re somewhere with harsh winters, your furnace will run more frequently, potentially making it wear out faster. The same goes if you like to keep your home at a warmer temperature.
Repair Frequency and Cost
Just like any appliance, as furnaces age, the likelihood for frequent furnace repair goes up. If your system is more than 15 years old, those repairs can be particularly costly. Common and expensive repairs on an older furnace include:
- Blower motor failures
- Ignition control failures
- Heat exchanger failures
If repairs are more than the half the cost of a new furnace, it’s generally recommended to replace it.
Furnaces older than 15 years can be extremely inefficient. You could be wasting as much as 30% of the money you spend to keep your home warm. High energy costs and the desire to decrease energy use are also strong reasons to consider replacing your furnace. In fact, an independent study by Decision Analyst reveals nearly 20% of homeowners who recently replaced their furnace specifically did so to lower their energy bills.
