Sell Through & EnergyGuide InformationNew 2023 EnergyGuide Label SamplesThe Federal Trade Commission requires energy labeling for major home appliances and other consumer products to helpconsumers compare the energy usage and costs of competing models. As a result of the DOE’s new minimum efficiencies andtesting requirements, the FTC published rule amendments updating the EnergyGuide labels with new descriptors – specifically theSEER2, EER2 and HSPF2 ratings.Consequently, all 2023-compliant products will include a new EnergyGuide label with the SEER2, EER2 and HSPF2 ratings clearlynoted as applicable. Examples of what the new Split System Air Conditioner, Split System Heat Pump, and Small Package Productlabels will look like can be found below. 2023-compliant products that begin shipping in calendar year 2022 will have these new labels.U.S. GovernmentFederal law prohibits removal of this label before consumer purchase.Central Air ConditionerCooling OnlySplit SystemXYZ CorporationModel NH65Efficiency Rating (SEER2)*Least Efficient19.0Federal law prohibits removal of this label before consumer purchase.XYZ CorporationModel 6645Heat PumpCooling and HeatingSplit SystemFor energy cost info, visitproductinfo.energy.govMost Efficient14.3-16.014.3Range of Similar ModelsLeast Efficient* Seasonal Energy Efficiency Ratio 242.0Most EfficientRange of Similar Models* Seasonal Energy Efficiency Ratio 2NoticeFederal law allows this unit to be installed only in:AK, AL, AR, CO, CT, DC, DE, FL, GA,HI, ID, IL, IA, IN, KS, KY, LA, MA, ME,MD, MI, MN, MO, MS, MT, NC, ND,NE, NH, NJ, NY, OH, OK, OR, PA, RI,SC, SD, TN, TX, UT, VA, VT, WA, WV,WI, WY, and U.S. territories.HeatingEfficiency Rating (HSPF2)*7.5Federal law prohibits installation of this unit in other states.Energy Efficiency Ratio 2 (EER2): This unit’s EER2 is 10.5.Split System Air ConditionerSample LabelLeast Efficient14.6Most EfficientFederal law prohibits removal of this label before consumer purchase.Central Air ConditionerCooling OnlySingle PackageXYZ CorporationModel NH6514.0This system’sefficiency ratings dependon the coil your contractorinstalls with this unit.

The DOE has been aggressively enforcing efficiency standards in a number ofindustries, including HVAC, and violations can be costly.llllD ealers and contractors caught installing non-compliant equipment will beforced to replace the equipment at their cost. Repeat violators can be put on anational do-not-sell list.D istributors are subject to the same do-not-sell penalty if they knowingly andrepeatedly supply non-compliant equipment to contractors who install thatequipment in violation of the regional minimum. ny distributor or contractor identified as a routine violator will be prohibited fromApurchasing any of the seven classes of products identified in the Code of FederalRegulations, 10-CFR-430.32. Manufacturers knowingly selling non-compliant equipment will also face stiff fines.We anticipate the DOE will allow easy and confidential reporting of suspectedviolations, and will make every effort to investigate credible complaints. In addition,manufacturers will be obligated to report any potential violations we identify orbecome aware of to the DOE within 15 days of discovery.In 2015, the DOE cracked down with big finesfor violators, including a 1.2 million fine toHVAC manufacturers.Sell Through & EnergyGuide Information7

Protect Your BusinessTRAININGSo how can you prepare to safeguard your business? The first step istraining. As 2023 draws nearer, the 2023 minimum efficiency standards willbe easily accessible on the Internet, including the DOE web site. Day & Nightwill also be creating training materials and continually communicating withyou as we get closer to the deadline. We will make every effort to ensurethat you are being supplied with region-appropriate products that meet allefficiency requirements for your area. However, it is important for you toprotect your business by learning the efficiency standards for your regionand placing product orders accordingly.Visit MLCtraining.com today and search 2023 in the online course catalog and video section to access available training.FUTURE RECORD KEEPINGBeginning in 2023, be prepared for record keeping. Dealer/contractors,distributors, and manufacturers will all be required to track the model andserial numbers of equipment sold, delivered and installed, as well as deliveryaddresses and installation locations. This includes cash sales. These recordswill protect you in the event of a DOE investigation. If 2015 is any indicationfor 2023, they will need to be kept for up to 60 months, depending on the typeof business:- 48 months for dealers / contractors- 54 months for distributors- 60 months for manufacturersIn summary, treat this information like you would treat your tax records,just to be safe.MAKE THE COMMITMENTRemember, we ALL have a stake in this. As your trusted supplier, we will invest the timeand resources to make compliance as easy as possible. That includes training, updatedproduct labeling, and continued communications about this topic.In the end, we encourage you to make the commitment as well. Start preparing now bygetting up to speed on the upcoming 2023 regulations and taking advantage of yourresources.

Key MessagingNew government regulations will be changing products throughout the entire HVAC industry, affecting manufacturers ofresidential cooling and heating products. Here’s a brief outline of what’s happening:Dealer Messagingl Every six years the U.S. Department of Energy (DOE)reanalyzes the effect of energy usage, sets minimumefficiency requirements and manages the testing standardsby which those efficiencies are measured. For 2023, theDOE is increasing the minimum efficiencies for central airconditioners and heat pumps. The testing procedures fordetermining those efficiencies will change as well.Consumer Messagingl– The DOE regional breakdown by state: Southwest: Arizona, California, Nevada, and New Mexico South: Alabama, Arkansas, Delaware, Florida, Georgia,l TheDOE’s new minimum efficiency standards and testingprocedures will be enforced for all HVAC manufacturersstarting on January 1, 2023.meet these new standards, 100% of current productsacross all tiers will need to be re-rated using the new testprocedures.Hawaii, Kentucky, Louisiana, Maryland, Mississippi,North Carolina, Oklahoma, South Carolina, Tennessee,Texas, Virginia, the District of Columbia, and theU.S. territoriesl Tol Themajority of product tiers and tonnages will be availableon or before January 1, 2023.llW e are instituting a phased roll out, with products launchingahead of deadline starting early 2022, to ensure readinessbefore January 1, 2023. Dependent on what area of the country a homeowner livesdetermines what air conditioners they can buy. That’sbecause the DOE has put in place new minimum efficiencystandards by region. North: The remainder of the United StateslH omeowners buying new Day & Night 2023-compliantsystems will benefit from:–A higher energy-efficient system leading to potentiallyreduced monthly utility bills.–E nhanced comfort benefits such as more consistent indoortemperatures and improved humidity control.I n addition, our regulatory-ready products are beingredesigned with an expected change in refrigerant tominimize future product transitions. We expect the newrefrigerant requirements to take effect in 2025.Key Messaging9
