SEER Ratings Explained: Choosing Energy Efficient AC Units

May 26, 2025 By: One Way Heating & Cooling

If you're shopping for a new air conditioner in El Paso, you’ve probably come across the term SEER rating. At first glance, it might sound like just another techy acronym that doesn’t mean much, but trust us, it matters. SEER ratings are one of the most important factors to consider when choosing a cooling system that’ll keep you comfortable and save you money.

In this guide, we’ll break down everything you need to know about SEER ratings, how they affect your energy bills, and what you should consider when choosing an energy-efficient AC unit. And of course, we’ll share how One Way Heating & Cooling can help you find the perfect fit for your home in El Paso, TX.

What Is a SEER Rating?

SEER stands for Seasonal Energy Efficiency Ratio. It measures how efficiently an air conditioner or heat pump can cool your home during a typical cooling season. The higher the SEER rating, the more energy-efficient the unit is.

To put it simply:
Higher SEER = Lower energy bills.

SEER ratings are determined by dividing the cooling output of a unit (in BTUs) over a cooling season by the energy it consumes (in watt-hours) during that same period. But you don’t have to do any math, just know that a unit with a SEER of 16 will generally perform better and cost less to operate than one with a SEER of 13.

Why SEER Ratings Matter in El Paso

Living in El Paso means long, hot summers. That means your air conditioner isn’t just a luxury, it’s a necessity. And because it works overtime for several months out of the year, efficiency makes a huge difference.

Here’s how SEER ratings affect you directly:

Lower utility bills: A high-efficiency AC unit can cut down your monthly electric bill significantly.
Environmentally friendly: The less energy your system uses, the smaller your carbon footprint.
Better indoor comfort: Newer, high-SEER systems often come with advanced features like variable-speed motors that keep your home cooler and more consistent in temperature.
Long-term savings: While high-SEER units may cost more upfront, they often pay for themselves through energy savings in just a few years.

Understanding SEER Ratings by the Numbers

Here’s a quick breakdown to help you compare:

13–14 SEER: These are older or basic models. They meet the minimum federal standard in some regions but may not be ideal for places like El Paso with extreme heat.
15–16 SEER: A step up in efficiency. These units are more affordable and offer decent savings.
17–20 SEER: These are high-efficiency models that offer advanced features like variable-speed compressors.
21+ SEER: Top-tier units, often with smart home integrations and the latest in comfort technology.

The minimum SEER rating allowed by the U.S. Department of Energy in Texas is 15 as of 2023. So if you’re replacing an older unit with a lower rating, you’re likely to see immediate improvements.

SEER Isn’t Everything - What Else to Consider

While SEER is a crucial factor, it’s not the only one. You should also think about:

Size of the Unit (Tonnage): Bigger isn’t always better. An oversized unit can short-cycle and lead to uneven cooling and higher bills.
Installation Quality: Even the most efficient AC unit won’t perform well if it’s not installed properly.
Maintenance Access: High-efficiency units need regular maintenance to stay in peak condition.
Upfront Costs vs. Long-Term Savings: Higher-SEER systems cost more, but rebates and energy savings can offset that quickly.

One Way Heating & Cooling specializes in helping homeowners like you balance all these factors to get the best bang for your buck.

What a SEER Upgrade Can Do

Let’s say you currently have an old unit with a SEER of 10. If you upgrade to a 16 SEER unit, you could reduce your cooling costs by up to 40%. Over time, that’s hundreds, if not thousands, of dollars in savings.

Now factor in how many scorching days El Paso gets each year, and it’s easy to see why making the switch is a smart move.

How to Choose the Right SEER for Your Home

So, how do you know which SEER rating is right for you?

Ask yourself these questions:

How long do you plan to stay in your current home? If it’s your forever home, a higher SEER makes more sense.
What’s your current energy usage? If your bills are sky-high, an efficiency upgrade could offer immediate relief.
Do you want advanced features? Higher-SEER units often come with extras like smart thermostats, zoning options, and humidity control.
Are you eligible for rebates? Energy-efficient systems often qualify for local and federal incentives. One Way Heating & Cooling can help you navigate those opportunities.
