How new industry standards could affect your home, your comfort, and your wallet!

The Department of Energy’s (DOE) new energy efficiency testing standards are now in full effect as of January 1, 2023. That means the DOE will begin using a new M1 testing method that better represents actual field conditions and, in turn, be reflected in new SEER ratings: SEER2, EER2, and HSPF2.

SEER is the ratio of an air conditioner’s cooling output, in a typical warm season, over the energy used in Watt-Hours. The SEER ratio takes into account an entire cooling season by using a variety of outdoor temperatures that range between 60 degrees to 100+ and a near constant indoor temperature.

Those acronyms and numbers are easy to understand…by HVAC professionals, but we find that most customers care primarily about two things: will this change make my new comfort system more efficient and more affordable?

We want our customers to be as educated as possible about a purchase as important as this, so we’ve compiled the most frequently asked questions our customers ask about the new SEER ratings. Be sure YOU ask them whether you’re working with the friendly, skilled, and trustworthy technicians at One Hour Heating and Air…or using another service provider.

1. What do the new 2023 HVAC regulations mean for any new system I buy?

Under previous regulations, the minimum efficiency SEER for new HVAC installations was 14.0 SEER for Southern areas (13.0 SEER in Northern regions).

Now, in the Southeastern U.S., the new SEER ratings will be:

  • For split system ACs ( AC < 45K Btu/h) = 15.0 SEER and 14.3 SEER 2
  • For split system ACs (AC > 45K Btu/h) = 14.5 SEER and 13.8 SEER 2

2. Who set these new SEER standards?

The U.S. Department of Energy (DOE) periodically evaluates current technology, its efficiency, and the cost of that technology to find the right balance. More efficient systems reduce the energy needed to heat and cool homes and businesses and therefore cost less to operate, but usually have a higher first cost.

3. What if I bought a new system right before January 1, 2023? Do I have to upgrade or pay more?

No! The 2023 requirements only apply to new systems purchased after January 1, 2023. Existing systems will not need to be replaced if they are already installed and still function properly.

If you are nearing the end of your current unit’s lifecycle, we understand that the upfront investment in a new comfort system can feel daunting. However, with the immediate energy savings you’ll enjoy on your monthly electric bill and those savings compounded over time, you will see a notable ROI with an equipment upgrade. You’ll also avoid the increasingly expensive maintenance and repairs inherent in nursing along an aging or modified system. One Hour Heating and Air is an industry leader in financing options and programs that put high-efficiency, high quality HVAC systems within your budget range. Plus, you’ll rest easier knowing your modern comfort system reduces your home’s carbon footprint and is a better option for the environment in which you and your family live and play.

3. Many HVAC companies will still have stock in their warehouse that, while brand new, does not meet the new testing standards for the 2023 SEER ratings. What happens if an HVAC supplier installs a non-compliant unit in my home?

The DOE will be enforcing regional standards. If an installer is in violation of one of these new standards, they will have to replace the non-compliant AC unit(s) at no cost to the consumer. Manufacturers and distributors may be unable to continue doing business if they face routine violations (10 CFR 429.102(c) Violations of regional standards).
