The U.S. Department of Energy (DOE) regularly updates efficiency standards for commercial heat pumps (HPs) and packaged air conditioners (ACs). These rules are part of a six-year cycle designed to reduce nationwide energy use, improve equipment performance, and lower long-term operating costs for building owners.
The latest updates include:
- 2025 Test Procedure Update: Beginning May 15, 2025, all equipment must be rated using revised test procedures. These introduce new performance metrics — IVEC (Integrated Ventilation, Economizer, and Cooling) and IVHE (Integrated Ventilation and Heating Efficiency) — in addition to familiar ratings like IEER and COP.
- 2023 Standards: Required a combined 30% increase in efficiency over the prior 2010 baseline for equipment ranging from 65,000 to 760,000 BTU/h.
- 2024 Direct Final Rule: Issued May 20, 2024, raising the bar again. Manufacturers must comply with new efficiency levels starting January 1, 2029.
What This Means for Your Facility
- Higher efficiency = lower operating costs. Future equipment may cost more upfront but will help control utility expenses over time.
- Testing changes reflect real-world use. New procedures measure ventilation and economizer performance more accurately, ensuring ratings better reflect how equipment performs in the field.
- Long-term planning is essential. With compliance set for 2029, facility managers should start factoring upcoming requirements into their capital planning.
- Lead times can be a factor. Commercial HVAC equipment can have significant lead times, especially for large systems. Planning ahead helps avoid downtime when replacements or upgrades are needed.
- Maintenance matters. Keeping systems in peak condition helps maximize performance, extend life, and prevent costly downtime.
Steps You Can Take Now
- Stay ahead with proactive maintenance. Regular inspections detect small problems before they become big repairs. Explore our Planned Maintenance Agreements.
- Plan replacements early. If your equipment is aging, start evaluating options now — well before the 2029 compliance deadline.
- Schedule an energy assessment. A professional evaluation can determine whether upgrading to higher-efficiency commercial heat pumps or packaged ACs makes sense today.
- Build a long-term roadmap. Anticipate future efficiency updates and testing standards in your facility planning to avoid surprises.
