How Much Does a Furnace and AC Replacement Cost in Atlanta, GA? [2026 Data]

In Atlanta, GA, replacing both a furnace and AC unit costs an average of $7,508 with most projects falling between $5,005 to $12,513. If your HVAC system is old or wearing out, you can give it new life with a full replacement. Let’s review how to budget for the cost of replacing your furnace and AC in Atlanta, GA.

Furnace and AC Replacement Cost Factors 

When you’re ready for a new heating and cooling system in your Atlanta, GA home, you’ll have to make decisions about type, size, brand and more to calculate your estimated cost.

Type of HVAC System

There are four types of HVAC systems, including split systems, duct-free systems, hybrid systems, and packaged heating and air systems. The typical cost ranges for each are:

• Split systems: $3,800–$7,500

• Duct-free systems: $2,000–$14,500

• Hybrid systems: $2,500–$10,000

• Packaged heating and air systems: $10,000–$14,000

Unit Size

The square footage of your house will determine what size furnace and air conditioner you need to heat or cool your space efficiently. A local HVAC company can help you determine what size you need exactly by doing a load calculation.

Unit Brand

An HVAC unit costs about $4,750 on average, but the brand you buy can change this number. For example, brands like Amana or Coleman tend to come in the lower end of the spectrum at $3,000, while brands Trane and York are often $6,000 or more. Keep in mind, if you’re replacing both heating and cooling systems, you’ll need multiple new units. 

HVAC Pro Costs

Replacing furnace and AC units isn’t a DIY job. In Atlanta, it’s illegal for unlicensed homeowners to install or replace a HVAC system. Plan to hire an Atlanta HVAC specialist so you can ensure your furnace and AC is replaced with the right type and size system for your home’s needs.

Hourly rates for Atlanta HVAC pros can range from $30 to $60 per hour or more. You can expect a full replacement project to fall on the higher end of the cost because it requires pros with more experience, plus four to eight hours of labor. Consult your HVAC contractor about bundling costs to include labor fees for easier budgeting.

Don’t forget to plan for annual maintenance visits to tune-up your system with a cleaning and inspection. Schedule annual HVAC maintenance with a pro to take care of filter replacements and other necessary tasks to keep your heating and cooling system in working order. 

Does Replacing Your AC and Furnace Increase Home Value?

The average ROI of this project is around 30%. Given the costs of replacing both furnace and AC system, that leads to an average increase in home value of 5% to 7%. That’s especially true if you’re replacing old units and upgrading to systems with higher energy-efficiency ratings, which means homeowners will save money over time. 

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
