As the summer heat rises in Charlottesville and across Albemarle County, your air conditioner becomes one of the most important systems in your home. It keeps you cool and comfortable, but it can also lead to high energy bills if your system isn’t running efficiently. At Fitch Services, we want our customers to understand the key factors that affect air conditioner efficiency—especially the SEER rating.
But what is a SEER rating, and why does it matter for your energy bill? In this article, we’ll break down what SEER ratings are, how they affect your home’s cooling costs, and what you should know when shopping for or maintaining an air conditioner.
What Is a SEER Rating?
SEER stands for Seasonal Energy Efficiency Ratio. It’s a number that tells you how efficient an air conditioner or heat pump is during the summer. In simple terms, the higher the SEER rating, the more cooling you get for each unit of electricity your system uses.
Think of SEER like the miles-per-gallon (MPG) rating for your car. Just like a car with better MPG saves you money on gas, a higher SEER-rated AC unit saves you money on electricity.
Why SEER Ratings Matter for Your Energy Bill
In the hot summers, your Charlottesville HVAC system works hard to keep your home cool. The more efficient your system is, the less energy it uses to do the same job. That’s why SEER ratings play a big role in how much you’ll pay each month.
For example, let’s say your current AC unit has a SEER rating of 10. If you upgrade to a unit with a SEER rating of 16, you could reduce your energy use by over 30% for the same amount of cooling. That adds up fast, especially in a long, hot summer. For perspective, approximately 60 – 70% of your total electric bill could be from running your heat pump/AC equipment, so it’s easy to see the impact of energy savings with more efficient equipment.
What Is a Good SEER Rating?
Today, federal regulations require all new central air conditioners to have a minimum SEER rating of 14 in our region. But some systems go as high as 26 SEER or more.
Here’s a simple way to think about it:
- 14–16 SEER – Basic efficiency (meets current minimum standards)
- 17–20 SEER – High efficiency (better energy savings)
- 21+ SEER – Ultra high efficiency (best performance, often includes smart features)
However, higher SEER units often cost more upfront, so it’s important to find a balance that works for your budget and energy goals. It’s important to note that equipment loses efficiency as it ages. So a 20-year old 10 SEER heat pump is no longer operating at that level of efficiency. An upgrade from an older system to a new system will be even greater.
How SEER Ratings Connect to Ductwork and AC Maintenance
It’s important to remember that your AC system’s SEER rating is just part of the story. Even a high-SEER unit won’t perform well if the rest of your system isn’t in good shape. That’s where air conditioning maintenance and ductwork come in.
Leaky ducts, dirty filters, or worn-out parts can make your system work harder than it should, reducing the efficiency promised by the SEER rating. Regular air conditioning maintenance—like cleaning coils, checking refrigerant, and inspecting electrical parts—helps keep your system running like it should.
Likewise, your home’s ductwork plays a big role. Poorly sealed or poorly designed ducts can cause cool air to leak before it even reaches your rooms. That’s like throwing money out the window!
If you’re not sure about the state of your system, a professional inspection from Fitch Services can help identify issues with your Charlottesville ductwork, maintenance needs, or whether it’s time to consider a more efficient unit.
Common Questions About SEER Ratings and Energy Use
- How can I find my air conditioner’s SEER rating?
Most units have a sticker or plate on the side that lists the model number and SEER rating. If you’re not sure, give us a call—we can help identify it for you. - Does a higher SEER rating always mean I’ll save money?
Not always. While higher SEER units use less electricity, the amount you save depends on your local climate, how often you use your AC, and the condition of your ductwork and insulation. - Can I upgrade just part of my system to improve SEER?
Sometimes, but it’s not always recommended. Your AC system works as a whole—if you replace just the outdoor unit and not the indoor coil, they might not match properly, which can lower efficiency and even void warranties. - Is a high-SEER unit worth it if I don’t use my AC much?
If you live in a mild climate or only use your AC occasionally, a basic unit with a SEER rating of 14–16 might be fine. But in Charlottesville, where summer can get quite hot and humid, higher efficiency often pays off over time. - What’s the best way to maintain my current system’s efficiency?
Schedule regular air conditioning maintenance, replace air filters monthly during heavy use, and have your ductwork inspected for leaks. These simple steps can help your current system perform at its best.

Final Thoughts
Understanding SEER ratings doesn’t have to be complicated. At its core, SEER tells you how efficiently your AC system can cool your home. The higher the number, the less energy it uses—and the more you can save on your power bill.
But SEER is just part of the story. Keeping up with air conditioning maintenance, checking your Charlottesville ductwork, and choosing the right system for your home are all key parts of staying cool and saving money during the hot Virginia summer.
