What Is The Difference Between 14 SEER And SEER2 AC Systems?

Couple of homeowners talking to the Bryant AC system installer

It’s no secret that air conditioning systems (AC Systems) have always impacted energy costs and the environment. That’s why The Department of Energy is always looking for new ways to improve energy efficiency and hold HVAC companies to a higher standard.

The efficiency of AC units is currently measured by two standards, EER and SEER. However, in 2023 HVAC companies will face new challenges and changes that impact these two universal standards.

Here’s everything you need to know about SEER2 and the sunsetting of 14 SEER AC units.

What is a SEER Rating?

SEER stands for Seasonal Energy Efficiency Ratio and is a measurement used to calculate your AC unit’s energy efficiency. SEER focuses on the seasonal aspect of the ratio.

You probably aren’t running your AC 24/7 at the highest possible setting, as warehouses and hospitals might be.

The SEER rating takes the weather and changing temperatures into consideration, looking at the efficiency of your unit during all seasonal changes.

To discover your AC unit’s seasonal efficiency, we measure the average EER during different temperatures and humidity levels. This is to gain a bigger picture of how well the AC works throughout the year. The higher the SEER rating, the more energy efficient your unit is.

For years, SEER has been the industry standard for measuring energy efficiencies. The SEER rating scale has been around for years and has been used by manufacturers. However, there are some inconsistencies in the SEER rating scale that the US Department of Energy plans to address.

What is SEER2?

In 2023, AC units will receive a SEER2 rating instead of a SEER rating. These changes in the rating scale are designed to make up for deficiencies that the SEER rating system lacked.

The Department of Energy is raising the testing conditions for the total external static pressure. The SEER testing conditions do not accurately consider the influence of ductwork on external static pressure.

With the current SEER rating system, the external static pressure test doesn’t accurately represent how AC units are used in homes.

The US Department of Energy developed these standards to measure appliance efficiency and provide manufacturers with a guide to help them calculate the efficiency of the equipment they sell before they put them on the market.

Why does this matter?

The Department of Energy wants to make AC units more energy efficient. With this change from SEER to SEER2 will come changes for the consumer.

For starters, the minimum SEER rating for each region will change. The minimum SEER rating varies by location and is based on The Energy Independence and Security Act of 2007. This is the regulated standard SEER efficiency.

Here is a look at the minimum SEER for the following locations as of 2022:

  • Northern states: 13 SEER
  • Southern and southeastern states: 14 SEER
  • Southwestern states: 14 SEER

As we transition to the SEER2 rating scale, these numbers will change. However, the SEER2 numbers are lower than the current SEER rating.

For example, in the Southeastern states, a minimum SEER2 rating of 14.3 will be required, which equals 15 SEER.

This means that 14 SEER AC units will be phased out, and new air conditioners will inevitably be more expensive. This is because it will cost manufacturers more to produce more efficient systems. However, switching to an efficient cooling system will help you save on energy costs.

What is happening with 14 SEER?

AC units with a 14 SEER rating are getting decommissioned. Since 14 SEER no longer meets the industry standard for most locations, you won’t be able to buy 14 SEER air conditioning systems after January 1, 2023.

If your AC unit breaks down, you likely wouldn’t be able to replace your unit with anything less than a 14 SEER. However, you will have an opportunity to invest in an efficient cooling system that pushes out reliable cooler air and helps you save on energy costs.

What happens if your current AC is lower than 14 SEER?

Don’t panic. The changes that are taking effect in 2023 are only for new AC units that are being installed. If you have an AC unit with 14 SEER or lower, you won’t be forced to replace your unit.

This is why you must contact Scott’s Air before the end of the year to get a more affordable system.

However, you should consider your central air conditioner for a more efficient cooling system in the future. According to the United States Energy Information Administration, the move from SEER to SEER2 will help save $2.5 to $12.5 billion on energy bills in the first 30 years.

Oh my god what an amazing company! I literally called one hour ago and said that my thermostat wasn’t working and there was a knock on my door within the hour! They told us what to do to fix it therefore saving us a $600 bill. They came right away, none of that we can see you in 48 hour junk. Amazing.

They were able to provide me with same day service, friendly and very responsive. Also, I got 2 other quotes and the pricing was the most competitive.
So thankful and impressed! My dad returned home after having open heart surgery to a completely dead HVAC system in the middle of summer. Definitely not ideal. The repair was going to be pricey so he opted for a new unit. A crew came out on a Saturday and did a very clean and efficient install. Highly recommend this company!!!

Very professional, work very neat and cleaned up and removed stuff. Very impressed with all of the staff and the company.
Our AC decided to quit during one of the hottest heatwaves in years. We called Scott's and someone was at the house to give us a quote in 30 min. From the moment they answered our first phone call through the install everyone was amazing, professional and provided a quality product and excellent service. Craig, Jose, Dexter were awesome! One of the new guys brought us a portable unit at 9:30 PM on a Friday so we could sleep. We missed his name, but shout out to him as well (he likes to give high fives). Thanks Scott and team for everything. We highly recommend!!!

For the past week I've worked with Craig on getting estimates for a new A/C unit, and he has been great at answering my questions and addressing any concerns. Very responsive and knowledgeable, straight shooter and direct! I didn't have to deal with any up-selling like working with a used car salesman (I experienced that with other bigger local A/C companies providing quotes). For these qualities alone I would recommend Scott's A/C, even though I will disclose that we ultimately went with another quote from a family referral of an A/C company. Had that family referral not been apart of our consideration, we would definitely choose and recommend Scott's for new A/C installs and service!
Dan in sales, outstanding jobgoing over equipment and helping us make what was the best decisions for us on purchasing new a/cinstall, plus scheduling the next day!Boris and Justin were excellent with communications while install and after! very clean, professional taking old out and installing new!ty
We can't thank Scott's enough. We came home to a air conditioner barely limping along. I called Scott's first thing in the morning and they had a technician out that day. Unfortunately our system could not be saved. The salesman Craig came out that day as well and quoted a new system. Since it was a Friday we could not get the system installed until Tuesday. Scott's provided us with a portable system which definitely helped during the grueling heat wave in Central Florida. Tuesday came, the installers showed up on time and did an awesome installation job. Cleaned everything up and went on their way. Everyone was pleasant, professional and great to work with! Thank You Scott's Heating & Cooling!

Always happy with their response time. Issue started last night causing our A/C unit to shut down. Made a call to Scott's Heating and Air in the morning and a tech was here by 10:45am. Tyrie, the tech, is awesome. He quickly took care of the problem and had us up and running in no time at all. He is knowledgeable and professional and did a great job.
Perfect company to do business with. Professional and courteous in all phases of project.

Excellent response and service. After 25 years of being serviced by a competitor I decided to change companies. AC was out and in need of replacement. Within 24 hours we had the sales rep here and new unit going in for a reasonable expense. No upselling, phony money savings, or timeshare presentations- just a new system without being targeted and pressured into pricey newer technology that will also become obsolete and non reparable every system cycle. I’m recommending to everyone looking for a new provider

Scott’s saved the day for us this evening. Our A/C stopped working and it got hot inside quickly, which was more complicated because I’m 36 weeks pregnant. Scott’s was responsive to our call and within two hours someone had come and fixed our unit!
