Understand SEER Ratings: Choose the Right AC for Your New Jersey Home

May 5, 2025

If you’re shopping for a new air conditioner, you’ve probably seen the term “SEER rating” pop up more than once. While it might seem like another bit of technical jargon, SEER actually plays a big role in how much comfort and efficiency you’ll get from your cooling system. At JAMCO Heating & Air Conditioning in Deptford Township, NJ, we help homeowners choose the best AC unit for their home and understand how SEER ratings will impact their choices.

What Is a SEER Rating?

SEER stands for Seasonal Energy Efficiency Ratio. It’s a number that helps you understand how efficient an air conditioner is when cooling your home. A higher number means the system uses less energy to cool the same amount of space. That can be good for your comfort and your electric bill. If you’ve looked at AC units before, you’ve probably seen these numbers listed on yellow EnergyGuide labels or spec sheets. They’re not just random. They come from real testing during warm weather, and they give you a way to compare one model to another. If your current system has a low SEER number, you might notice it struggles during hot months, or your bills get high fast. Upgrading to something with a higher SEER can help fix that.

How Does Climate Affect What You Need?

Not every home needs the same level of efficiency. Where you live changes what kind of air conditioner works best. In hotter, longer summers, a higher SEER unit often makes sense because your system runs more. The more it runs, the more you notice the difference in energy use. If your summers are shorter or milder, the difference between a 14 SEER and a 16 SEER unit might not save you much money. But if you get long stretches of hot, humid days, those higher numbers can pay off. You also have to think about humidity. Some newer systems remove moisture better than older ones, which helps your home feel cooler without lowering the temperature as much. That also helps if your allergies flare up with high humidity levels.

Is a Higher Seer Rating Always Better?

Not always. While it’s easy to think that higher is better, it depends on your budget and how much you use your AC. A very high SEER unit costs more to install. If you don’t use your AC much, it might take a long time to get those savings back. If you run your system almost every day in the summer, then the savings can add up quicker. Some high-SEER systems also include variable-speed compressors or smart technology. These features help with comfort and control, but they also add to the price. You might love the extra options, or you might want to keep things simple. That’s something to think about when you’re picking your system. A mid-range SEER unit might still give you great performance without the higher price tag.

How Does Your Current Setup Affect Your Choice?

Your home’s existing ductwork, insulation, and layout all play a part in which AC system works best. Suppose your ducts are leaky or poorly sized, even a high-SEER unit won’t perform like it should. Sometimes, fixing or sealing ducts before installing a new system gives you better results than going straight to the most expensive unit. The same goes for insulation and window quality. If your house loses cool air faster than it’s made, your system has to work harder, no matter the SEER rating. You should also think about how your home is used. Do you spend most of your time in one part of the house? Do you have guest rooms or areas you barely use? You might want a system that gives you more control over different zones. That way, you’re not cooling rooms you don’t spend time in.

What Else Should You Look for When Buying?

SEER ratings help you compare energy use, but you still have to think about the rest of the system. Look at warranty terms, sound levels, and how the unit fits into your space. If your outdoor area is tight or your indoor unit needs to go somewhere specific, that could affect which models work best. Also, think about who’s doing the installation. Even the best system can struggle if it’s not installed correctly. A well-done installation matters just as much as the equipment itself. It’s also smart to ask about rebates. Some states or utility companies offer money back to buy higher-efficiency systems. That can make a more efficient unit easier to afford and give you more choices when picking what works for your home.
