Buying a new furnace may not be a priority right away. But it’s wise to know the things that will likely impact your choice when you’re ready to buy. Here are seven things you’ll want to consider when you're due for furnace replacement in Shreveport.
1. Size and Installation Quality
To operate at maximum efficiency and comfort, your furnace must be properly sized for your home. When it involves furnaces, bigger is certainly not better. We often get requests from customers to install a big furnace in the misguided belief that a larger furnace is either more dependable or will provide better comfort.
The opposite is true. Large furnaces will short cycle, or continuously 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 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 crucial component of installation is ductwork. If yours is old or designed wrong, you might have issues with sound or comfort. A furnace is only as effective as the duct system it’s linked to.

Besides technical skill, our technicians are also trained in treating you ethically. We also stand behind our work with a 100% satisfaction guarantee for a year.*
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 wasted during the heating process.
If your present 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 wasting 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 consideration: blower technology. This part moves air throughout your home. And it also consumes a lot of electricity, so it’s important to be familiar with 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 standard 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 strikes a balance between price and energy efficiency. It provides an electrical efficiency boost over a standard 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 important 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 notice that your furnace is on.
5. Smart Thermostat
You probably use a programmable thermostat, but chances are you probably aren’t making the most of your energy savings. These thermostats can be complicated to program, especially if your schedule varies from day to day.
A smart thermostat eliminates all the guessing about energy efficiency. Many models can learn from your temperature preferences and then produce an energy-saving schedule to match. They also know when you’re home or away and will adjust your heating and cooling as necessary.
As an extra perk, you’ll also be able to monitor and change your settings from just about anyplace on your phone. Some models can even notify you if they detect a problem with your furnace or remind you when it’s time to replace your air filter.
There’s a major difference in furnace quality and reliability. Like any large purchase, we believe it’s best to go with a major brand name. With a leading 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 usually have two main warranty coverage areas:
- Heat exchanger. This is the heart 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 components. This involves the blower motor, electronic controls, ignitors and other key 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 cost of the replacement part, not labor. And labor on a replacing heat exchanger could get costly.
Once your new furnace is running, make sure you finish the product registration right away. Many manufacturers may reduce the warranty term if the product registration is not completed. This step is easy and usually 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 affect on your budget, remember 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 offers.
A couple of other ways to save include:
- Getting a new air conditioner simultaneously.
- Purchasing at the ideal 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 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 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 old one? Here are a few ideas from our Experts that will help you decide.
Heating systems typically last 15–20 years. How long yours will keep going 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 frequently, potentially making it wear out sooner. The same applies if you like to keep your home at a warmer 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 costly 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 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 energy bills.
