Replacing an HVAC system is one of the more significant investments a homeowner will make, especially in a climate like Savannah, Georgia, where both air conditioning and heating play important roles in year-round comfort. If your heating and cooling system is aging, failing, or inefficient, you may be wondering how much a full HVAC replacement will cost and what exactly goes into that number.
In this detailed guide, we’ll walk you through the average HVAC replacement cost in Savannah, explain the many variables that impact the final price, and give you tips to save money while choosing the right system for your home.
Whether you’re replacing a furnace, upgrading to a ductless mini split, or investing in a high-efficiency heat pump, understanding the financial landscape of HVAC replacement will help you make a smart, informed decision.
As of 2025, homeowners in Savannah can expect to pay between $6,500 and $12,000 for a full HVAC system replacement. This includes both the air conditioning and heating components, along with installation by a licensed HVAC contractor.
For smaller homes, systems may fall on the lower end of this range. Larger homes or high-efficiency systems, especially those with zoning features or advanced smart thermostats, will typically cost more.
Keep in mind that while the upfront investment may seem steep, replacing an outdated system with a modern, energy-efficient HVAC unit can dramatically reduce your monthly energy bills, improve indoor air quality, and keep your home comfortable through every season.
There’s no one-size-fits-all answer when it comes to HVAC system pricing. Several factors will impact the final cost of your replacement project, including:
The size of your HVAC system is one of the most important pricing factors. Residential HVAC systems are measured in tons, which refer to the system’s ability to cool your home efficiently. For example, a 1,500-square-foot home may only require a 2.5-ton system, while a 3,000-square-foot home may need a 4 or 5-ton unit.
Proper system sizing is crucial in humid climates like Savannah. Oversized systems can short-cycle and wear out faster, while undersized systems will struggle to keep your home cool and dry. A professional HVAC technician will perform a Manual J load calculation to determine the right size for your home.
There are several types of HVAC systems commonly used in Savannah homes, and the type you choose will directly influence your replacement cost.
Central air systems combine an outdoor AC unit with an indoor furnace or air handler and are the most common. Heat pumps provide both heating and cooling and are popular in Georgia’s mild winters. Ductless mini splits are ideal for homes without ductwork or for room additions and sunrooms. Dual-fuel systems combine a heat pump with a gas furnace for maximum efficiency.
Mini split systems typically cost less upfront but may require multiple indoor units for whole-home coverage. Heat pumps offer year-round efficiency but can cost more if high SEER and HSPF ratings are chosen.
The more efficient your HVAC system, the more it will typically cost upfront. However, this also means lower monthly utility bills and long-term savings.
In Savannah, where air conditioners run heavily through the hot summer, a SEER rating of 16 or higher is recommended. Higher SEER units use less electricity to cool your home, which helps fight those peak-season energy bills.
For heating components:
Choosing a high-efficiency unit may also qualify you for local utility rebates or federal tax credits, which can significantly reduce your net cost.
If your home’s ductwork is old, leaky, or poorly insulated, it may need repair or full replacement. In some cases, ducts are undersized or poorly laid out, creating airflow problems that reduce efficiency and comfort.
Ductwork modifications can add several thousand dollars to your HVAC replacement project, especially in older Savannah homes with difficult attic or crawl space access. However, addressing ductwork is critical to ensure your new HVAC system operates at peak performance.
Installation labor can vary based on the complexity of the job. Homes with hard-to-access attics, tight crawlspaces, or complicated electrical work may incur higher labor costs. Likewise, adding zoning systems, smart thermostats, or condensate pumps can increase installation time and complexity.

While the cost of HVAC replacement may seem high, the benefits are substantial, especially in Savannah’s hot, humid climate.
Older systems are not only less efficient but may also struggle to keep up with Georgia’s demanding summers. If your AC unit is more than 10 to 15 years old, chances are you’re overpaying for electricity and risking costly breakdowns during the peak cooling season.
Modern HVAC systems offer:
If your existing system is failing or frequently needs repairs, replacing it with an energy-efficient model can pay for itself over time through monthly savings and increased home value.
Looking to get the best value on your HVAC replacement? Here are a few tips that can help you save money while still getting a high-quality system:
Spring and fall are considered "shoulder seasons" in the HVAC industry. Demand is lower, and many contractors offer promotional pricing or faster scheduling. Avoiding peak summer can also help you avoid emergency replacement costs.
Georgia homeowners may qualify for rebates through Georgia Power or local energy programs. Additionally, the federal Inflation Reduction Act offers up to $2,000 in tax credits for qualified high-efficiency systems, including heat pumps and ENERGY STAR-certified equipment.
Be sure to ask your contractor about rebate processing and eligibility requirements.
Replacing an HVAC system is a large expense, but many reputable contractors, including Bell Air offer zero percent interest financing or flexible monthly payment plans. This can make replacing your system more affordable while still upgrading to a high-efficiency model.
Selecting the lowest quote isn’t always the best strategy. A poor installation can cause even the best HVAC system to underperform or fail early. Look for NATE-certified technicians, strong reviews, and companies that offer warranties on both parts and labor.
