When shopping for a new air conditioner, you’ll notice that each unit has a ‘SEER’ rating listed on the box. This rating measures how efficiently an AC cools your home, impacting your monthly energy usage and utility bills. While you may think a higher SEER rating is always best, it’s important to consider your budget, climate, and cooling needs before making a purchase.
In this guide, we’ll walk you through what SEER ratings mean in HVAC systems, how they affect your energy efficiency, and how to choose the right option for your home.
What is a SEER Rating?
A Seasonal Energy Efficiency Ratio (SEER) rating measures how efficiently your air conditioner uses energy to cool a space. Professionals calculate this rating by dividing the cooling output of an air conditioner during a standard cooling season by the amount of electricity it consumes. The higher the rating, the more efficient your system is.
In 2023, the Department of Energy revised the energy efficiency requirements for HVAC units, now using SEER2 ratings instead of SEER. While these ratings both measure energy efficiency, SEER2 testing procedures are much more intensive, which is why you’ll see lower SEER2 than SEER values for the same system.
Why is the SEER Rating Important?
Understanding SEER ratings is crucial when selecting an air conditioner, as they directly impact your energy costs and home comfort. Higher SEER ratings mean your AC operates more efficiently, helping to lower your energy usage and monthly cooling bills.
Greater efficiency also means your air conditioner uses less energy to cool your space, reducing wear and tear on components. You’ll experience fewer repairs, better indoor air quality, and have more consistent cooling.
Choosing the Ideal SEER Rating for Your Home
While many assume that the highest SEER rating available is the best option, that’s not always the case. The right AC SEER rating for your home depends on your local climate, budget, and energy goals.
If you live in a hot climate with long summers where your AC runs for an extended period of time, investing in a higher SEER helps combat long-term energy expenses. In mild climates that don’t require long-term AC usage, a lower SEER rating can help reduce your up-front costs, while still keeping your home cool when temperatures rise.
SEER Ratings and Cost-Benefit Analysis
Air conditioners with higher SEER ratings often come with a higher upfront cost. While you may pay more initially for these systems, the investment pays off over time through energy savings.
The higher your AC’s SEER rating, the less energy it uses to cool your home. While the exact amount you’ll save depends on factors like your climate, energy rates, and how often you use your system, these savings add up over time. In areas with long, hot summers and high AC usage, homeowners can save hundreds per year and thousands over the lifespan of their system.
Minimum SEER Ratings by Region
The Department of Energy (DOE) sets minimum requirements for SEER ratings based on regional climates. Homes in hotter climates are required to have a more efficient system than those in milder areas, which helps improve energy efficiency nationwide.
Here’s a look at the DOE’s regional breakdown:
- Southwest (ex., Arizona, California, Nevada, and New Mexico): 15.0 SEER/14.3 SEER2 minimum rating
- Southeast (ex, Alabama, Arkansas, Delaware, Florida, Georgia, Oklahoma): 15.0 SEER/14.3 SEER2 minimum rating
- North (ex., Colorado, Illinois, Ohio, New York): 14.0 SEER/13.4 SEER2 minimum rating
Common Myths About SEER Ratings
There are a few common myths about SEER ratings that can lead homeowners to make costly mistakes when purchasing a new air conditioner. Watch out for these common misconceptions to avoid making the wrong choice:
- A higher SEER rating is guaranteed to save you money: While units with high SEER ratings are more efficient, improper installation, lack of maintenance, and inefficient ductwork can prevent you from seeing those savings.
- The SEER rating is the only thing to consider when buying an AC: When purchasing an air conditioner, it’s important to also consider factors like its size, type, and features to make the right choice for your home.
- The highest SEER rating is the best choice: If you live in a mild climate and rarely use your air conditioner, purchasing a unit with the highest rating may not provide enough energy savings to justify the upfront cost.
- SEER ratings don’t affect your environmental footprint: Using a higher SEER system reduces your carbon emissions and environmental impact.

Frequently Asked Questions
Do I need to upgrade my air conditioner to a SEER2 rating?
If your air conditioner is in good condition, there’s no need to replace it just because of the new SEER2 standards. You can keep your existing system installed until it reaches the end of its lifespan, at which point we’ll be happy to help you find the right upgrade for your home.
Does a higher SEER rating mean a longer AC lifespan?
A higher SEER rating can contribute to a longer lifespan for your air conditioner. High-SEER systems often feature variable-speed compressors and advanced components that help reduce wear and tear, allowing your AC to run more efficiently for longer.
What’s the maximum AC SEER rating?
Central air conditioners can achieve a SEER rating of up to 25, with some mini-split systems reaching even higher. These systems often come with a high upfront cost and are best for homes in extremely hot regions with long cooling seasons.
