Purchasing a new furnace may not be a concern in the immediate future. But it’s wise to learn the things that will likely impact your selection when you’re ready to buy. Here are seven things you’ll want to think about when you're due for furnace replacement in Atlanta.
1. Size and Installation Quality
To operate at maximum efficiency and comfort, your furnace must be correctly sized for your home. When it involves furnaces, bigger is certainly not better. We often get requests from customers to purchase 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 cold, with more expensive energy bills and a furnace that could wear out 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 lose as much as 30% of your energy efficiency.
Another key component of installation is ductwork. If yours is old or improperly designed, you might have issues with noise or comfort. A furnace is only as effective as the duct system it’s linked to.

In addition to technical skill, our technicians are also trained in treating you fairly. We also stand behind our work with a 100% satisfaction guarantee for a year.*
2. Energy Efficiency
Furnaces are rated 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 higher the number, the less gas is spent 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 evaluate new furnaces there is one more important consideration: blower technology. This part moves 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 today. 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 expensive 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 running at full speed 24/7, they will quietly run 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 in check.
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 be aware that your furnace is on.
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 varies from day to day.
A smart thermostat removes all the guesswork about energy efficiency. Many models can pick up on 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 an extra perk, you’ll also be able to keep tabs on and adjust your settings from just about anywhere 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 significant difference in furnace quality and reliability. Like any large 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 confidence 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 heart 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 important parts. Warranties can vary from as little as a one-year limited warranty to as much as a 10-year limited warranty.
When going over warranty coverage, it’s important to know it's limited. So, you should make sure you get the limitations. For example, nearly all standard manufacturer warranties only cover the price of the replacement part, not labor. And labor on a new heat exchanger could get very expensive.
Once your new furnace is installed, make sure you finish the product registration immediately. Many manufacturers may limit the warranty term if the product registration is not done. This step is simple and usually 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 other ways to save include:
- Replacing your air conditioner at the same time.
- 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 less busy 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 enroll in 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 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 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 frequently, potentially making it wear out faster. The same applies 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 goes up. If your system is more than 15 years old, those repairs can be especially expensive. 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 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 decrease energy use are also strong reasons to think about 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 energy bills.
