The HVAC industry is currently navigating a period of uncertainty, following several regulatory changes initiated during the Trump administration. These actions, many of which were designed to reduce federal oversight and prioritize economic flexibility, have had wide-reaching effects on energy efficiency initiatives, refrigerant transitions, and incentive programs. As a result, stakeholders across the industry are assessing how best to move forward.
Refrigerant Transition Slows
One of the most notable shifts has been in the refrigerant transition process. Under the Obama administration, the EPA began phasing down the use of hydrofluorocarbons (HFCs)—greenhouse gases commonly used in air conditioning and refrigeration—through its Significant New Alternatives Policy (SNAP) program.
As Trump took office order were given to roll back some of these policies. The EPA’s revised approach allows individual states to determine their own refrigerant regulations, which has led to a varied regulatory landscape across the country. While states like California have maintained aggressive HFC reduction goals, others have opted to pause or reevaluate their approach. This divergence has introduced complexity for manufacturers, contractors, and distributors operating across multiple states.
Energy Efficiency Standards Delayed
The Department of Energy (DOE) has also postponed the implementation of updated HVAC efficiency standards. These updates were part of a routine review process to ensure HVAC systems meet evolving energy performance benchmarks. Delaying these updates is intended to provide manufacturers additional time to adjust, but it has also left questions about when new standards will take effect and how they may be enforced moving forward.
For the industry, this means that expected product design changes, training needs, and performance requirements remain in a state of pause. Stakeholders are continuing to prepare, but the absence of a clear timeline presents planning challenges.
Impact on State Rebate Programs
Another development is the suspension or delay of certain state-run HVAC rebate programs. Some states have paused incentive programs that encourage the purchase of energy-efficient HVAC systems. These programs have traditionally helped homeowners and businesses offset the cost of new equipment and boost adoption of high-efficiency technologies.
Without those incentives, adoption rates for newer technologies may slow, particularly in regions where upfront costs remain a barrier. The long-term impact of these delays is still unfolding, and many states are evaluating their options based on available funding and guidance.
A Broader Deregulatory Approach
The EPA described these actions as part of a broader effort to reduce regulatory burdens, streamline compliance, and support economic growth. These policies were consistent with the administration’s emphasis on deregulation across various industries. In the HVAC sector, the practical outcome has been a shift in how quickly or consistently federal standards are implemented or enforced.
What Comes Next?
With the industry in transition, stakeholders are watching closely to see whether existing policies will remain in place, be reinstated, or evolve. Many companies continue to pursue energy efficiency and low-GWP refrigerant goals independently, driven by market trends, consumer demand, and international regulations.
However, until a clearer federal direction is established, the pace and uniformity of the HVAC energy transition may continue to vary by region and sector.
