What Is a SEER Rating?
SEER stands for Seasonal Energy Efficiency Ratio. It is a rating that measures the efficiency of an HVAC system over the course of an entire season. Think of it like miles per gallon for your car. It tells you how much energy your system uses to keep your home comfortable. The higher the SEER rating, the more efficient the system.
In 2023, the industry updated how these systems are tested to better reflect real-world conditions. These updated ratings are called SEER2. The idea is simple. Give homeowners a more accurate picture of how their system actually performs, not just how it performs under ideal lab conditions.
So why should you care about SEER or SEER2?
Because it directly impacts your monthly utility bills, and the long-term cost of owning your system.
If you already have a system, understanding its SEER rating can help you evaluate how it is performing today. If your system has a high SEER rating but still seems inefficient, the issue is usually not the equipment itself. It is often tied to installation, environmental conditions, or maintenance. Things like leaky ductwork, improper system sizing, or lack of regular service can prevent even a high-efficiency unit from operating at its full potential.
SEER ratings also help you make smarter decisions when it comes to upgrading. Systems below 13 SEER are typically older and significantly less efficient. Upgrading to a system rated 16 SEER2 or higher can reduce energy consumption by more than 35 percent. Units in the 13 to 14 SEER range are not drastically inefficient, but if they are more than 10 to 12 years old, they are likely no longer performing anywhere near their original rating. Systems rated 14 to 15 SEER2 meet the current minimum standards in many regions as of 2023. The best SEER2 for your HVAC will vary based on your climate and budget. For many of us here in the Midwest, a 16-18+ SEER2 system provides a great balance of value and energy savings.
Another reason SEER matters is rebates. Utility companies and manufacturers often offer incentives for installing higher-efficiency equipment. In many cases, the amount of savings correlates directly to your new units SEER number. Often, the higher the SEER, the more you save.
HVAC accounts for more than half of residential energy use in the United States, so improving efficiency benefits everyone. It helps stabilize energy demand, reduces strain on the grid, and lowers costs for homeowners. It is one of the most practical ways to save money at home while also contributing to a more sustainable future.
While navigating rebates can feel overwhelming, working with a knowledgeable HVAC professional like Summit Heating, Cooling, and Plumbing can simplify the process. In many cases, they can help identify which programs you qualify for and even handle the paperwork. Programs like Evergy’s FastTrack HVAC Pays are designed to make upgrades more accessible and affordable for homeowners who qualify.
SEER vs. SEER2: What Changed?
SEER and SEER2 both measure cooling efficiency, but SEER2 uses updated testing standards that better reflect how HVAC systems perform once installed in real homes. The newer SEER2 testing process accounts for higher external static pressure, which makes the rating closer to real-world operating conditions.
If your system was installed before 2023, it may still show a SEER rating instead of a SEER2 rating. If you are shopping for a new air conditioner or heat pump today, you will most likely see SEER2 used on newer equipment.
What is my system’s SEER rating?
If you are not sure what your current system’s SEER rating is, there are a few ways to find out. You can check the EnergyGuide sticker on your unit, look up your model in the AHRI directory, or have a professional Summit Heating, Cooling, & Plumbing HVAC technician take a look.
Can I improve my system’s SEER rating?
While you cannot change the official SEER rating of your existing system, you can absolutely improve how efficiently it runs. Regular maintenance goes a long way. Changing your 1” air filter every 30 days or 5” filter every 6 months, keeping coils clean, and clearing debris from around your outdoor unit all help maintain proper airflow. Sealing and cleaning ductwork can eliminate major energy losses. Installing a smart thermostat can reduce energy use by automatically adjusting temperatures when you are away or asleep. Upgrading certain components, like adding a variable-speed furnace or air handler, can also improve performance. On top of that, improving your home’s insulation and sealing air leaks helps keep conditioned air inside where it belongs. Of course if you’re not sure where to start, your Summit Heating, Cooling, & Plumbing technician can always help you identify areas for improvement or perform your seasonal maintenance and remove the guesswork for you.
At the end of the day, SEER is about how hard your system has to work to keep you comfortable. The higher the number the more efficient it is, the less energy it uses, and the more money you keep in your pocket over time. And if you have any questions you can always reach out to the great folks at Summit Heating, Cooling & Plumbing for all your indoor comfort needs.
