The HVAC industry will see a few new changes in the year 2023. With the pandemic causing issues with production, installation, supply, and so on, the industry suffered a lot. And with 2023 knocking on our doors, we must be updated about the changes. So, let us dive in and get to know about the new changes making their home in the world of HVAC systems.


What Are the New HVAC Changes?

There are quite a few changes introduced in the HVAC industry by the Department of Energy (DOE). These standards will go into effect starting from 1st January 2023. The new changes have been introduced in terms of the minimum efficiency of heating and cooling systems along with the testing standards of the systems.

  • New 2023 Testing Standards

In the year 2023, the test standard for HVAC systems will undergo a major change as well. It is known as the M1 standard for HVAC testing. The purpose of these new standards is to ensure that the data values, metrics, and test conditions introduce a more accurate and reliable performance of the HVAC systems.

Currently, HVAC systems are tested in terms of SEER, EER, and HSPF. However, according to upcoming standards, tests will be conducted in terms of SEER2, EER2, along with HSPF2. In this test, the external static pressure will increase five times. This change is introduced to ensure accurate HVAC external static pressure is found.

  • New Minimum Efficiency Standards for Split HVAC Systems

For the North region, a 13.4 SEER2 rating is a must for all split systems in the HVAC systems. This SEER2 rating is equivalent to the SEER rating of 15.

For the Southeast region, split HVAC systems with BTU/h less than 45k will have a SEER2 rating of 14.3. SEER2 14.3 is equal to 15 SEER. With systems of more than 45k Btu/h, the SEER2 rating is 13.8, which is equal to 14.5 SEER.

In the Southwest region, less than 45k Btu/h systems will require a SEER2 rating of 14.3 and an EER2 rating of 11.7. In terms of SEER and EER standards, these ratings are 15 SEER and 12.2 EER, respectively. On the other hand, in cases of systems with more than 45k Btu/h, the SEER2 rating is 13.8 and 11.2 for EER2. 13.8 SEER2 equals 14.5 SEER, and 11.2 EER2 is equivalent to 11.7 EER.

HVAC systems manufactured before 2023 cannot be installed after 1st January 2023. This means that the manufacturers will have to redesign the entire system to match the standards coming into effect soon.

  • National Standards for Split Heat Pump Systems In 2023

Similar to split HVAC systems, the standards for split heat pump systems are also changing from 2023. The minimum efficiency of the split heat pumps will be changed from 14 SEER to 14.3 SEER2 or 15 SEER. In addition, the 8.2 HSPF will change to a 7.5 HSPF2 rating or 8.8 HSPF. In this case, systems manufactured before 2023 can be installed without any restriction as long as they meet the new standards.

  • New National Standards for Packaged HVAC and Heat Pump Systems

In terms of packaged HVAC and heat pump systems, no new regulations or standards are being introduced in the industry. However, these systems must match the new testing standards with a SEER2 rating of 13.4 (equal to 14 SEER) and an HSPF2 rating of 6.7 (HSPF 8.0). This means that there is no need to redesign the systems to match the requirements.

What Do These New Standards Mean for The HVAC Customers?

The new standards mentioned above do not only affect the HVAC systems. But these new standards will also be a new experience for the HVAC customers. While installing or looking for a new HVAC system in cases of both split and packaged systems, customers must consider the new standards.

HVAC systems or heat pumps with new standards and high efficiency will undoubtedly be costlier compared to the old ones. The cost of these new systems will increase up to $300-$1500. While this is a significant price hike, the improved performance will help to save money on electricity bills and repairs or replacements.


Final Note

The HVAC industry plays a major role when it comes to the comfort and peace in our homes. The Department of Energy works on HVAC units to ensure efficient performance and reduce energy consumption for a better environment. As part of the HVAC industry, we are dedicated to making your lives easier while caring for the world. So, let us move forward and work towards an energy-efficient and smart world.
