Purchasing a new furnace may not be a concern in the immediate future. But it’s wise to learn 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 it’s time for furnace replacement in Charleston.
1. Size and Installation Quality
To run at maximum efficiency and comfort, your furnace must be properly sized for your home. When it involves furnaces, bigger is certainly not better. We frequently get requests from customers to purchase a big furnace in the mistaken belief that a larger furnace is either more reliable or will offer better comfort.
The reverse is true. Large furnaces will short cycle, or constantly 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 right size but installed wrong, the U.S. Department of Energy says you could forfeit as much as 30% of your energy efficiency.
Another key component of installation is ductwork. If yours is old or designed wrong, you might have issues with noise or comfort. A furnace is only as effective as the duct system it’s attached to.

2. Energy Efficiency
Furnaces are ranked by a term called 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 ranked 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—highest 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 important to know about your options.
There are three types of blowers available on furnaces nowadays. They include:
- Standard blower motor. Furnaces that aren’t ENERGY STAR rated have a standard 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 strikes a balance between cost and energy efficiency. It delivers an electrical efficiency boost over a traditional motor design.
- Variable-speed motor. The most energy-efficient furnaces can operate at different speeds. Instead of running at full speed 24/7, they will quietly operate at a low or medium speed at times. This helps enhance your comfort while keeping energy costs low, both in the winter and summer. And it also keeps indoor humidity in check.
4. Sound Reduction Technology
Sound has become a very significant consideration with furnace installation, so another dramatic improvement has been keeping noise under control. 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 on.
5. Smart Thermostat
You probably have 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, particularly if your schedule changes from day to day.
A smart thermostat eliminates all the guesswork about energy efficiency. Many models can learn from your temperature preferences and then create an energy-saving schedule to match. They also know when you’re home or away and will adjust your heating and cooling as needed.
As a bonus, you’ll also be able to monitor 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 believe it’s wisest 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 uphold its product warranty over the long term.
Furnaces typically have two primary warranty coverage areas:
- Heat exchanger. This is the center of the furnace and the costliest component to replace. This part usually has a 20-year limited warranty or lifetime limited warranty, but this can differ based on the manufacturer and furnace model.
- Main parts. This involves the blower motor, electronic controls, ignitors and other key parts. Warranties can range from as little as a one-year limited warranty to as much as a 10-year limited warranty.
When reviewing warranty coverage, it’s essential to know it's limited. So, you should make sure you understand the limitations. For instance, nearly all standard manufacturer warranties only include 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 complete the product registration right away. Many manufacturers may reduce the warranty term if the product registration is not completed. This step is simple 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 buy, your new furnace may help pay for itself from the monthly energy savings it offers.
A couple of other ways to save include:
- Replacing your air conditioner simultaneously.
- Buying at the right time, such as in early fall, mid-winter and early spring. You may be able to get extra discounts and rebates during this slower season.
- Reap the benefits of rebates from the federal and state government, as well as from your local utility provider. 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 get 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 tips from our Experts that will help you make that decision.
Heating systems typically last 15–20 years. How long yours will last depends on whether you’ve kept up with furnace maintenance, where you live and your temperature preferences. If you’re in a place with harsh winters, your furnace will operate more often, potentially making it wear out sooner. The same goes if you like to keep your home at a warmer temperature.
Repair Frequency and Cost
Just like any appliance, as furnaces get older, the likelihood 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 more than the half the cost 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 keep your home warm. Excessive energy costs and the desire to reduce energy consumption 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 lower their utility bills.
