How Much Does a New Furnace Cost in Atlanta? [2025 Data]

The average new furnace cost in Atlanta, Georgia, is $3,849. However, you might pay between $2,103 and $5,607, depending on the type of furnace, the condition of your existing ductwork, and other factors. This guide breaks down how each of these variables affects your furnace installation costs so you can budget accordingly.

New Furnace Cost Factors 

The type and size of your furnace have a significant impact on your overall costs, but there are other factors at play, too. Here are the main ones.

Type of Furnace

From electric to natural gas to oil, the type of furnace you install will directly affect the price of your project. If you’re looking for a lower-cost or eco-friendly option, you could go with an electric furnace, which starts around $600. On the other hand, natural gas furnaces often cost more upfront but less to operate over time since natural gas prices tend to be lower than electricity prices.

Furnace Size

Your HVAC technician will determine the right size furnace for your home—another factor that will impact your final costs. Furnace sizes are listed in British thermal units (BTUs), which measure the unit’s heat output. As you might imagine, furnaces with higher BTUs can produce more heat, but they also come with higher price tags.

Again, it’s best to have a qualified HVAC pro choose your furnace size. To do this, they’ll use a complex formula—known as a Manual J load calculation—that considers your house’s square footage, insulation, ductwork, and a number of other factors. 

However, you can get an idea of how much different-sized gas furnaces cost in the table below. 

AFUE Rating

Your furnace’s AFUE rating, short for Annual Fuel Utilization Efficiency, measures the percentage of fuel it converts into heat. Furnaces with high AFUE ratings (90% or more) can be twice as expensive as standard-efficiency units with AFUE ratings between 80% and 89%. 

However, since higher-efficiency furnaces require less fuel to run, the long-term operating costs will be lower. Over time, that type of savings can add up, especially in Georgia, where natural gas prices are consistently higher than national averages, according to the U.S. Energy Information Administration (EIA).

Ductwork Replacement

In some cases, you'll have to replace your ductwork when installing a new furnace. For example, if there are leaks, cracks, or mold in your existing air ducts, your pro may recommend adding new ductwork.

On average, ductwork replacement costs between $440 and $1,290, but an HVAC pro can provide a specific quote based on your home size, duct locations, and other factors.

Furnace Removal and Disposal

If you already have a furnace, your furnace installation pro in Atlanta, Georgia, will need to remove it before installing the new one. They’ll typically charge a few hundred dollars to remove and responsibly dispose of the old furnace.

Furnace Pro Costs 

Beyond the costs of the furnace and ductwork, also plan for the following expenses.

Licensing and Certification

In Atlanta, when you contact an HVAC technician to install your new furnace, they must have a valid Conditioned Air Contractor license from Georgia’s division of Conditioned Air Contractors. Before hiring someone, confirm the status of their license on the Georgia Online Application Licensing System (GOALS) website.

You might also consider choosing a NATE-certified technician for this project. While optional, having a certification from North American Technician Excellence means the furnace pro near you has the proper skills and up-to-date industry knowledge to install your furnace correctly.

Permits

The city of Atlanta requires a mechanical permit for all furnace installations. When you hire a contractor for this project, they should obtain the permit on your behalf (and their quote should include the cost of the permit itself and any charges for pulling it).

In Atlanta, permit fees vary depending on the exact details of your project. But as an example, let’s say you’re planning to add a new furnace and replace some of your old ductwork at the same time. Here’s how Atlanta’s permit fee breaks down.

Does Installing a New Furnace Increase Home Value?

Georgia might not get as cold as some other states along the East Coast, but winter nights in Atlanta can still get quite chilly. By replacing an old or inefficient furnace before selling your home, you’ll make it more appealing to potential buyers—and increase its resale value in the process.

If you’re investing in a new furnace, it’s also worth considering upgrading your air conditioner at the same time. Having an updated cooling system is particularly attractive in Atlanta, where summers are notoriously hot and humid. After replacing both parts of your HVAC system, you could see a 5% to 7% increase in your home’s resale value.
