WASHINGTON — It has been just over a year since the signing of the One Big, Beautiful Bill Act (OBBBA), a sweeping legislative package that restructured federal tax policy, energy incentives, and workforce development funding as the centerpiece of the Trump administration’s first-year agenda. For the heating, ventilation, air conditioning, and refrigeration (HVACR) industry, the legislation has proven to be a double-edged sword—delivering long-sought permanence and expansion for business tax provisions while abruptly terminating popular consumer and commercial energy-efficiency credits.
As industry stakeholders evaluate the law’s performance twelve months down the line, the consensus is encapsulated by Mark Valentini, vice president for legislative affairs at the Plumbing-Heating-Cooling Contractors – National Association (PHCC): “You win some, you lose some.”
Main Facts: The Core Pillars of the OBBBA
The OBBBA instituted major structural shifts across the American economic landscape, directly impacting small businesses, commercial contractors, and everyday consumers. Its primary components affecting the trades include:
- Permanent Business Tax Relief: The law made permanent the 20% qualified business income (QBI) deduction for pass-through entities, which had been scheduled to sunset, and permanently secured 100% bonus depreciation for qualifying business property.
- Expanded Section 179 Expensing: Limits for Section 179 small-business expensing were significantly raised, offering immediate write-offs for equipment and capital investments.
- Termination of Green Energy Credits: The law repealed several major federal tax incentives, including the Section 25C Energy Efficient Home Improvement Credit, the Section 179D Energy Efficient Commercial Buildings Deduction, the Section 25D Residential Clean Energy Credit (covering solar and geothermal), and the Section 45L New Energy Efficient Home Credit.
- Workforce Development Overhaul: The legislation expanded Section 529 education savings accounts to cover skilled-trades training and introduced "Workforce Pell" grants to fund short-term credentialing programs for industries like HVAC.
Chronology: From Legislative Enactment to Market Realities
To understand the current state of the HVAC market, it is necessary to trace how the OBBBA has rolled out over the past year:
- Late 2024 / Early 2025: The OBBBA is introduced and swiftly passed as part of the administration’s aggressive first-year legislative push, designed to stave off looming tax hikes and enact sweeping structural reforms.
- Mid-2025: As the provisions take effect, small businesses breathe a sigh of relief as the QBI deduction and 100% bonus depreciation are locked in permanently. Simultaneously, homeowners rush to complete pending energy-efficient installations before the expiration of Section 25C and 25D credits fully takes hold.
- Late 2025: Industry groups assess the initial impact of losing consumer tax credits. Despite fears that the elimination of Section 25C would paralyze heat pump sales, early market data shows surprising resilience.
- Early 2026 (Present Day): One year post-enactment, contractors are leveraging expanded Section 179 limits and bonus depreciation for commercial projects, while utilizing newly unlocked Workforce Pell grants and 529 funds to combat ongoing labor shortages.
Supporting Data: Tax Savings vs. Shipment Numbers
The true impact of the OBBBA is best understood through hard economic and manufacturing data gathered during its first year of implementation.
The Tax Victory for Small Businesses and Commercial Clients
Prior to the OBBBA, small business owners faced a looming fiscal cliff. The 20% QBI deduction was set to expire, and bonus depreciation was on a scheduled phase-out path that would have reduced it to zero by 2027. By making these provisions permanent and enhancing Section 179 limits, the federal government prevented automatic tax increases.
According to Sean Robertson, vice president of government relations at the Air Conditioning Contractors of America (ACCA), these changes are funneling billions of dollars back into Main Street businesses. However, the commercial impact may be even more profound. “The combination of 100% bonus depreciation with enhanced Section 179 expensing means that commercial customers will be able to expense millions in upgraded equipment all at once rather than spreading those investments over time,” Robertson noted.
The Loss of Consumer Credits and AHRI Shipment Figures
Conversely, the removal of consumer-facing tax credits sent shockwaves through the residential market.
- Section 25C: Previously offered homeowners tax credits of up to $2,000 for qualified heat pumps, and up to $600 each for high-efficiency furnaces and air conditioners. According to U.S. Department of the Treasury figures, over 2.3 million households claimed the 25C credit in 2023 alone, with nearly 268,000 of those claims dedicated to heat pumps.
- Section 179D: This permanent deduction for energy-efficient commercial buildings was entirely wiped out, leaving commercial contractors without a vital tool to incentivize green building upgrades.
Despite the elimination of the $2,000 heat pump credit, early shipment data from the Air Conditioning, Heating, and Refrigeration Institute (AHRI) defies pessimistic predictions. During the first six months of the year, residential heat pump shipments actually rose by 3.8% compared to the same period in the previous year when the 25C credit was fully active. Residential air conditioning shipments also saw a modest increase of 2.4%, while residential furnace shipments declined by 6.2%.
Note: AHRI shipment figures do not distinguish between units that qualified for the defunct 25C tax credits and those that did not, leaving analysts to debate whether broader market demand or underlying inflation is driving the numbers.
Official Responses: Industry Leaders Weigh In
Trade associations representing the HVAC and plumbing sectors have offered nuanced perspectives on the OBBBA, balancing gratitude for tax continuity against deep frustration over lost energy incentives.
- PHCC’s Perspective: Mark Valentini of the PHCC emphasized that the regulatory environment has stabilized for contractors who feared tax hikes. However, he noted that the practical effects of losing incentives like Section 25C and 179D remain “mixed across the country,” varying heavily by local utility rebates and regional climate needs.
- ACCA’s Perspective: Sean Robertson did not mince words regarding the elimination of green incentives, calling the termination of the 179D commercial deduction “profoundly disappointing.” He pointed out that soaring equipment prices were already cooling the market for high-efficiency systems, making it difficult to fully isolate the market damage caused by the loss of the $2,000 heat pump credit.
- Workforce Consensus: Both ACCA and PHCC praised the OBBBA’s education provisions. By integrating skilled-trades training into Section 529 savings plans and introducing Workforce Pell grants, Congress signaled a major shift in how federal policy views non-college career paths.
Implications: What the OBBBA Means for the Future of HVAC
As the industry looks beyond the one-year mark of the OBBBA, several critical implications are emerging for contractors, manufacturers, and consumers.
1. The Shift to Commercial Capital Investment
With 100% bonus depreciation and enhanced Section 179 expensing secured permanently, commercial HVAC contractors are poised for a boom in large-scale retrofits. Building owners can now write off massive equipment upgrades immediately rather than amortizing them over decades. This makes large commercial projects financially attractive even in the absence of Section 179D deductions.
2. Adaptation to Life Without Consumer Incentives
The resilience of heat pump shipments demonstrates that consumer demand for modern, efficient equipment is driven by more than federal tax credits alone. Factors such as long-term energy savings, state and local utility rebates, consumer awareness, and emergency replacement needs (when a system breaks down mid-summer or winter) continue to sustain market volume. Nevertheless, contractors operating in lower-income demographics or regions lacking robust local rebates report a harder sell on premium-tier high-efficiency units.
3. A New Frontier for Workforce Development
Perhaps the most universally praised aspect of the OBBBA for the trades is its forward-thinking approach to labor shortages. For years, finding and retaining qualified technicians has been cited by ACCA members as the single greatest threat to business growth.
By opening Section 529 plans and Pell Grants to short-term trade schools and HVAC certificate programs, the federal government has lowered the financial barrier to entry for prospective technicians. Industry leaders argue this proves lawmakers are finally waking up to the realities of the skills gap.
Building on this momentum, trade organizations are already pushing for supplementary legislation. Key targets include:
- The Employer Directed Skills Act: Designed to provide flexible training funds that contractors can directly leverage.
- The Workforce Apprenticeship Growth and Education Support (WAGES) Act: Aimed at creating tax credits for employers who invest in registered apprenticeship programs.
Conclusion
One year after the passage of the One Big, Beautiful Bill Act, the HVAC industry has adapted to a restructured regulatory environment. While the loss of consumer and commercial energy credits remains a bitter pill for advocates of green building, the preservation of foundational small business tax reliefs and the historic pivot toward federal funding for trade education have provided the industry with robust tools for long-term survival and growth. As Mark Valentini observed, the trade-offs are real, but HVAC contractors have proven they know how to adjust their thermostats and keep moving forward.
