What is the change?
Effective January 1, 2023, there will be new minimum efficiency standards for split-system air conditioners and split-system heat pumps. As well as a change to the efficiency rating test procedure, known as the “M1 Standard,” which will affect split-system air conditioners, splitsystem heat pumps and packaged units. As in the past, these standards vary by both product type and geographic region.
About every six years, the Department of Energy evaluates energy conservation standards for most of the appliances you have in your home or those in commercial buildings. When DOE evaluates the need for a new standard, they decide whether there are significant national energy savings if the standard is increased.
Testing to a Higher Standard
To comply with a new, more stringent testing protocol for reporting efficiency ratings, Manufacturers are required to:
• Re-test equipment to the new efficiency rating test requirements
known as the “M1 Standard.”
• Publish equipment efficiency ratings using the new efficiency metrics of SEER2, EER2 and HSPF2. Compared to the current test procedure the new test procedure increases the external static pressure from 0.1-0.3 ESP to 0.5 ESP to better reflect field conditions, for heat pumps a more representative heating load line will also be implemented. Since the new testing requirements are more stringent, in 2023, there will be new metrics and nomenclature – SEER2, EER2 and HSPF2. Here’s what will go into effect beginning January 1, 2023.
