A new Senate bill could reshape how future HVAC equipment standards are written.
Utah Senator Mike Lee introduced the Energy Efficiency Reform Act of 2026, a bill that would overhaul how the Department of Energy sets energy-efficiency standards for home appliances and equipment, including air conditioners and water heaters. The bill would require DOE to finalize its proposed process-rule changes within 270 days.
For HVAC contractors, this is a major regulatory story.
DOE efficiency standards directly affect what equipment manufacturers build, what distributors stock, what contractors sell, and what homeowners can buy. Even when the rulemaking sounds procedural, the effect eventually reaches the jobsite.
Why This Is Huge
The bill would do more than adjust DOE’s internal process.
It would also void the long-contested 95% residential gas furnace rule, block states from banning products based on fuel source, including natural gas, and remove the requirement that DOE review standards every six years.
That makes this a direct HVAC contractor issue. The 95% furnace rule has been one of the most consequential regulatory fights for residential heating contractors because it could affect non-condensing furnace availability and retrofit costs.
The Contractor Impact
If the bill advances, contractors could face a very different regulatory path for furnaces, air conditioners, water heaters, and other covered products.
Supporters say the bill would slow constant product changes and protect consumer choice. Critics argue it could make it much harder for DOE to update efficiency standards and could increase household utility bills.
Contractor Takeaway
This belongs near the top of the newsletter.
The bill is not law yet, but it is exactly the type of legislation contractors need to watch. It could affect equipment availability, replacement costs, customer choice, and future sales conversations around efficiency.
For contractors, the message is simple: regulation is still one of the biggest forces shaping the HVAC market.
