New HVAC Equipment Minimum Efficiency and M1 Testing Standards

New HVAC Equipment Minimum Efficiency and M1 Testing Standards

Every six years, the United States Department of Energy (DOE) reviews the energy efficiency of various home appliances as a means of assessing if improvements are necessary and viable to help reduce overall energy demand. During this assessment, if it is determined improvements are necessary and attainable, more stringent efficiency requirements will be planned. When the most recent assessment was held, it was determined that HVAC equipment was in need of an upgrade in efficiency.

On January 1, 2023, new minimum efficiency standards on all new HVAC equipment will take effect. In this post, we’ll tell you what you need to know to prepare for the forthcoming changes and what they could mean for your home or business.

New HVAC Regulatory Requirements: What You Need to Know

New HVAC minimum efficiency standards will go into effect on January 1, 2023. This will primarily affect property owners that need new HVAC equipment installed after this date. These regulations will not require property owners to update any existing equipment.

The new regulatory requirements apply to the following HVAC equipment:

  • Split air conditioners
  • Heat pumps
  • Packaged units
  • Ductless units

System Installation vs. Manufacturing Date

All major manufacturers are currently developing new heating and cooling products to comply with these new efficiency standards. However, there is one notable exception property owners should be aware of.  Required efficiency standards will vary based on the region where the new equipment is to be installed. For instance, for northern U.S. property owners, compliance with these new standards is determined by the manufacturing date of the HVAC equipment. For southern-based property owners, compliance is necessary by the January 1, 2023 deadline.

Furthermore, efficiency standards for these regions vary slightly as do the regulations related to which equipment meets these standards. 

Why the Change?

Similar to how the automotive industry is being challenged with improved fuel efficiency standards, the HVAC industry is now being challenged with reducing its overall energy consumption. It’s estimated that HVAC energy usage, specifically air conditioning, accounts for about 10 percent of total global electricity consumption – and this figure is set to become even greater over the next several decades.

While these changes are challenging for manufacturers, they do have positives for both homeowners and the environment. New air conditioners, for instance, can reduce cooling costs by up to 40 percent versus a similar system that is only a decade old. New higher efficiency units may also keep a property more comfortable while reducing cooling costs.

New M1 Testing Standards

Another key change is that efficiency ratings for both air conditioners and heat pumps will also adjust. Current SEER (Seasonal Energy Efficiency Ratio), EER (Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings will now become SEER2, EER2 and HSPF2 come January 1, 2023. These ratings will be calculated by up to 5 times the static pressure used in today’s testing procedure, which will represent a reduction in today’s rated efficiency.

As a result of these changes, minimum energy efficiency is expected to increase by at least 7 percent overall.
