Buying a new furnace may not be a concern in the immediate future. But it’s wise to know the things that will likely influence your selection when you’re ready to buy. Here are seven things you’ll want to consider when you're due for furnace replacement in Charlotte.
1. Size and Installation Quality
To run at maximum efficiency and comfort, your furnace must be correctly sized for your home. When it involves furnaces, bigger is definitely not better. We often get requests from customers to purchase a big furnace in the mistaken belief that a larger furnace is either more reliable or will provide better comfort.
The reverse is true. Oversized furnaces will short cycle, or constantly turn on and off. This leaves you uncomfortable, with higher energy bills and a furnace that could need replacing much sooner.
This is why it’s important to work with the right company when buying a new furnace. Even if it’s the right size but improperly installed, 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 improperly designed, 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 rated by a term known as AFUE, or annual fuel utilization efficiency. Like miles per gallon on cars, this measures the annual gas consumption of a furnace. The greater the number, the less gas is spent during the heating process.
If your present 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 now:
- 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 compare new furnaces there is one more important thing to consider: blower technology. This part circulates air throughout your home. And it also uses a lot of electricity, so it’s essential to know about your options.
There are three kinds of blowers available on furnaces nowadays. They include:
- Standard blower motor. Furnaces that aren’t ENERGY STAR rated have a traditional blower motor that’s been mostly the same for the past 30 years. This motor is the least costly and also the least energy efficient.
- Constant torque motor. This technology finds a balance between price and energy efficiency. It delivers an electrical efficiency boost over a standard motor design.
- Variable-speed motor. The most energy-efficient furnaces can run at different speeds. Instead of operating at full blast 24/7, they will quietly run at a low or medium speed at times. This helps improve your comfort while keeping energy costs low, 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 great 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 be aware that your furnace is running.
5. Smart Thermostat
You probably have a programmable thermostat, but chances are you probably aren’t maximizing your energy savings. These thermostats can be complicated to program, particularly if your schedule changes from day to day.
A smart thermostat eliminates 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 find a problem with your furnace or remind you when it’s time to change your air filter.
There’s a major difference in furnace quality and reliability. Like any large purchase, we think it’s best to go with a major brand name. With a top brand like Lennox® or Goodman®, you’ll have more assurance in the technology and that the manufacturer will stand by its product warranty over the long term.
Furnaces typically have two main warranty coverage areas:
- Heat exchanger. This is the heart of the furnace and the costliest component to replace. This part typically has a 20-year limited warranty or lifetime limited warranty, but this can vary based on the manufacturer and furnace model.
- Main components. This involves the blower motor, electronic controls, ignitors and other important parts. Warranties can vary from as short 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 limitations. For example, nearly all standard manufacturer warranties only include the price of the replacement part, not labor. And labor on a new heat exchanger could get costly.
Once your new furnace is running, make sure you complete the product registration immediately. Many manufacturers may reduce the warranty term if the product registration is not done. This step is simple and typically only takes a few minutes.
How much does all this cost anyway? It could vary from $1,700 for a basic furnace, or $5,500 or more for a high-efficiency model.
As you consider these costs and the impact to your budget, remember that unlike nearly every other appliance you may need to buy, your new furnace may help pay for itself from the monthly energy savings it offers.
A couple of additional ways to save include:
- Replacing your air conditioner at the same time.
- 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 less busy season.
- Reap the benefits of rebates from the federal and state government, as well as from your local utility company. We can help you figure out this process.
- Finance your new furnace or sign up for our exclusive HVAC Advantage Program™. For just one low monthly fee, you’ll receive a new furnace with repairs and maintenance included.*
How Do I Know When to Replace My Furnace?
Now that you know what to look for in a new furnace, when should you replace your old one? Here are a few ideas 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 kept up with furnace maintenance, where you live and your desired temperature. If you’re in a place with harsh winters, your furnace will run more often, potentially making it wear out sooner. The same goes if you like to keep your home at a hotter temperature.
Repair Frequency and Cost
Just like any appliance, as furnaces age, the potential for frequent furnace repair increases. 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 greater than the half the price of a new furnace, it’s generally best to replace it.
Furnaces older than 15 years can be very inefficient. You could be throwing away as much as 30% of the money you spend to heat your home. Excessive energy costs and the desire to reduce energy use are also strong reasons to consider replacing your furnace. In fact, an independent study by Decision Analyst shows nearly 20% of homeowners who recently replaced their furnace specifically did so to reduce their utility bills.
