Installing a new central air conditioning unit—or replacing your current AC unit—can feel like a big leap. There’s a lot to think about: size, features, indoor air quality upgrades, your budget, and which air conditioning installation company you can trust. But one of the most important things to consider? The SEER rating.
At Thiele Heating & Air Conditioning, we help Central Indiana homeowners make smart, informed choices about their cooling systems every day. If you’ve been researching a new AC installation or just want to know what SEER means for your current air conditioning system, you’re in the right place.
Let’s break it down.
What Is a SEER Rating?
SEER stands for Seasonal Energy Efficiency Ratio. It’s a measurement of how efficiently a central air conditioning system or heat pump operates over an entire cooling season.
Here’s the short version: the higher the SEER rating, the more energy-efficient the system is. That means lower cooling costs on your energy bills without sacrificing comfort.
A SEER rating is calculated by dividing the total cooling output of a system over a season by the total energy it uses in watt-hours. All central air conditioners and air-source heat pumps have a SEER rating—it’s required by the Department of Energy.
Here are a few benchmarks to keep in mind:
- Older AC units often have SEER ratings of 8–10.
- The minimum SEER rating allowed for new air conditioner installation in Indiana as of 2023 is 14.
- Energy-efficient systems typically start at SEER 16 and go up from there—some high-performance models exceed SEER 20.
In Central Indiana and the Indianapolis area, a SEER rating between 15 and 18 is a smart balance of cost and performance. But every home is different, and we’re happy to help you choose what works best.
Where Can I Find the SEER Rating of My Air Conditioner?
If you’re not sure how efficient your current AC system is, check the yellow EnergyGuide label usually located on the side of your outdoor AC unit or heat pump. The SEER rating will be printed clearly on this label.
No luck there? You can also check your system’s model number or owner’s manual—or give Thiele a call and one of our HVAC technicians will help you figure it out.
If you’re shopping for a new air conditioning unit, SEER ratings are included in all product literature and spec sheets. Our team can walk you through your options during your consultation and show you which air conditioning models meet your energy efficiency goals.
Benefits of a High SEER-Rated Air Conditioning System
A higher SEER rating doesn’t just look good on paper—it can make a real difference in your comfort, your energy usage, and your wallet. Here’s how:
Lower Cooling Costs
A more energy-efficient system uses less power to cool your home, which means lower energy bills every month. In fact, upgrading from a SEER 10 system to a SEER 16 can save you up to 40% on your cooling costs, depending on your home and usage.
Greater Comfort and Performance
Newer air conditioner models with higher SEER ratings often come with variable-speed compressors and advanced fan motors. These features help your system maintain a more consistent indoor temperature and better humidity control, even on the hottest days.
Quieter Operation
High-efficiency AC units tend to operate more quietly, which is great news if your current air conditioner makes a racket every time it kicks on. With a new air conditioning system, you’ll stay cool without the constant hum or buzz.
Better for the Environment
Higher SEER systems use less electricity, which reduces the demand on the power grid and your carbon footprint. Many are also compatible with newer refrigerants that are safer for the environment.
Improved Indoor Air Quality
Energy-efficient systems often come with optional indoor air quality add-ons like air purifiers, dehumidifiers, or UV lights. This means not only cleaner, fresher air—but healthier air, too.
A Smarter Long-Term Investment
Yes, higher SEER systems may come with a higher upfront cost—but the energy savings, improved comfort, and longer system lifespan make it well worth it. You’re not just investing in a reliable air conditioning system that performs better for years to come—you may also be eligible for tax incentives or rebates that help offset the initial cost. We’ll help you explore those options and find the best fit for your home and budget.
