Winter temperatures in Georgia can fluctuate throughout the state, with lows often falling below freezing. To keep your home warm and cozy, it’s important to have an efficient and effective furnace.

If your heating is no longer able to keep up with your needs, it may be time for a furnace replacement, but should you also replace your AC?

In this article, the HVAC experts at United Air Temp discuss the benefits of replacing your furnace and AC together and the risks of pairing a new furnace with an older AC, to help homeowners make the right choice for their homes and comfort. 

Benefits of Replacing Your Furnace & AC Together

There are many benefits for homeowners who combine heating replacement with AC replacement for a total HVAC replacement.

Optimized Heating & Cooling Performance

Modern HVAC systems are designed to work as a unit. That’s why we recommend matched systems, as they improve performance and efficiency.

Systems of the same age will provide consistent airflow and temperature regulation to ensure your total comfort during all seasons.

Improved Energy Efficiency

Because new HAC systems have higher efficiency ratings, homeowners benefit from having two systems with upgraded technology.

Systems with similar efficiency will work together more seamlessly and result in improved performance.

Plus, replacing both systems allows you to take full advantage of the latest energy-efficiency technology. New air conditioners comply with the 2025 refrigerant updates.

Maximized Cost Savings

A full HVAC replacement saves costs upfront and over time. Having your furnace and AC installed simultaneously reduces labor and installation costs, while greater efficiency for both systems can result in long-term energy savings.

Many incentives, including federal tax credits and local rebates, are available to offset the cost of replacements. 

Furnace vs. Air Conditioner Lifespan

While furnaces tend to last longer than AC units, it’s recommended to replace both if your furnace is over 15 years old.

This is especially true in Georgia, where your air conditioner is used more than your furnace, which means your AC will likely have a shorter lifespan.

Why Mismatched HVAC Systems Aren’t Recommended

There are many issues that come with choosing to run a new furnace with an older AC. These include:

• Reduced energy efficiency
• Higher energy bills
• Imbalanced airflow
• Inconsistent comfort 
• Added wear and tear
• Greater chance of a breakdown
• More costly repairs
