Preparing for New Efficiency Standards
A regulatory shift you can't afford to miss
New HVAC efficiency standards and the A2L refrigerant transition are rewriting the rules for contractors. This guide breaks down what's changing, what it costs to ignore it, and how field data positions your team to stay ahead.
What's actually changing
SEER2 minimums, A2L refrigerant requirements, and regional compliance rules are already in effect; this guide explains what applies to you.
The real cost of unpreparedness
Contractors caught without updated workflows and equipment data face compliance failures, warranty issues, and lost customer trust.
How field data helps
Knowing the refrigerant type and efficiency rating of every unit in your portfolio turns compliance from a scramble into a planned transition.
Who needs this guide
HVAC contractors, service managers, and technicians responsible for equipment compliance across commercial and residential systems.
Preparing for New HVAC Efficiency Standards
The HVAC industry continues to evolve as new federal efficiency regulations reshape equipment standards, manufacturing requirements, and field service operations.
Beginning January 1, 2023, the Department of Energy (DOE) implemented updated efficiency standards for split system air conditioners and split system heat pumps as part of a broader initiative to reduce national energy consumption.
Understanding the New DOE Requirements
Under the updated standards, split system air conditioners and heat pumps are required to meet higher minimum energy efficiency thresholds.
These changes impact:
- SEER (Seasonal Energy Efficiency Ratio) ratings for air conditioners
- HSPF (Heating Seasonal Performance Factor) ratings for heat pumps
The DOE periodically reevaluates energy conservation standards to determine whether updated efficiency requirements are technologically feasible and economically justified. The previous HVAC efficiency standards were introduced in 2015.
Changes to Testing and Performance Procedures
In addition to increasing minimum efficiency requirements, HVAC manufacturers are also required to follow updated testing procedures designed to better reflect real-world operating conditions in the field.
These testing changes are intended to improve consistency between laboratory efficiency ratings and actual equipment performance during day-to-day operation.
The Industry’s Readiness Challenge
While awareness of the upcoming regulations is relatively high across the HVAC industry, many organizations have not fully prepared for implementation.
Industry survey data has shown that:
- A large majority of HVAC professionals are familiar with the new regulations
- Many contractors and service organizations have yet to develop action plans or implementation strategies
This gap between awareness and preparation highlights the operational complexity involved in adapting to changing efficiency standards.
Operational Impacts for Contractors and Service Teams
New efficiency standards affect more than equipment manufacturing. Contractors, distributors, technicians, and service organizations must also adapt their workflows, inventory planning, installation practices, and customer communication strategies.
Key operational considerations include:
- Equipment compatibility and inventory management
- Updated installation requirements
- Technician training and education
- Customer communication and quoting processes
- Compliance documentation and reporting
Preparing for Long-Term Industry Change
As HVAC regulations continue evolving, organizations that invest in education, operational planning, and connected service workflows will be better positioned to adapt successfully.
Modern field service technology and centralized operational knowledge can help service teams respond more efficiently to regulatory changes while improving consistency across installation and maintenance processes.
By proactively preparing for updated efficiency standards, HVAC organizations can reduce disruption, improve operational readiness, and better support customers throughout the transition.
