Nothing. There will be no changes to product designs, part numbers, or model numbers for any Bosch heat pumps as a result of the DOE 2023 requirements.***
The Steps We Are Taking
Environmental stewardship is a core philosophy that inspires and drives Bosch global product development. Bosch Thermotechnology strives for high efficiency in its products and is wellpositioned to meet the new, federally mandated minimum efficiency standards.
▶ Summer 2022: Bosch will complete re-rating the entire Bosch unitary heat pump portfolio. Before 2023: Bosch will add the new performance data (SEER2/ HSPF2) to AHRI and update these ratings in all of our technical documentation.

2023 Minimum Efficiency
*15.0 SEER up to 45k BTU, 14.5 SEER at/above 45k BTU, ** External Static Pressure, ***Any 14.0 SEER heat pump built before Jan 1, 2023 can still be installed on or after Jan 1, 2023. Change
For 2023, the DOE has reanalyzed and increased the minimum efficiency levels accordingly. For air conditioners in the North, the minimum efficiency will increase from 13.0 to 14.0 SEER and in the South from 14.0 to 15.0 SEER* under today’s test procedure. The national heat pump minimum efficiency will increase from 14.0 to 15.0 SEER. Distributors can be banned from selling equipment if found to be selling non-compliant products. Dealers and contractors found installing noncompliant equipment must replace the equipment at their own cost. Repeat violators can be banned from purchasing equipment. Change
What Do You Need to Do?
How is Bosch Responding? Before we design our products, we always consider the customer's journey and the evolution of technology. Because of Bosch's commitment to innovation, we are proud to be one of the first manufacturers to offer a fully DOE 2023 compliant heat pump portfolio without disrupting anything for our customers.
Effective in 2023, the United States Department of Energy (DOE) is increasing the minimum efficiencies for central air conditioners and heat pumps. These new regulations are part of the DOE's ongoing initiative to reduce overall energy consumption in the United States. The testing standards will be updated accordingly.
HVAC manufacturers will be required to follow a new testing procedure for developing efficiency ratings. With this change, the static pressure used when testing will be increased by up to 5X. The goal of this change is to develop a more rigorous method of testing that better reflects field conditions (see graphic below). Because efficiency ratings will be affected as a result of this new standard, there will be new metrics and nomenclature – SEER2, EER2 and HSPF2. Please note: ▶ The new SEER2 ratings will be lower and the minimum efficiencies will be reduced to account for the more difficult test procedures, compared to the SEER ratings on the same system – e.g. the North region’s 15.0 SEER minimum efficiency under the current test procedure will become a 14.3 SEER2 under the new test procedure. ▶ All tiers of products will need to be retested, optimized, and relaunched in accordance with the new test procedure - resulting in a much larger scale project for manufacturers compared to prior minimum efficiency changes. ▶ The new test procedure will also drive changes to the airflow set point on indoor blowers (air handlers and furnaces).
