The Big, Beautiful Bill’s Impact on the HVAC Industry

U.S. Capitol building symbolizing legislative changes impacting the HVAC industry, relevant to the "Big Beautiful Bill" discussion.

The recently passed "Big Beautiful Bill" is set to have some significant impacts on the HVAC industry. This legislation presents both promising opportunities and challenges that those in the HVAC sector should be aware of, which this post will discuss.

Positives for the HVAC Industry

One notable benefit of the bill for the HVAC industry is the expansion of permissible uses for 529 education savings plans. Previously, 529 plans were restricted to college tuition. However, now these plans can be utilized for career certifications, apprenticeships, and licensing programs, including HVAC training. This change opens new avenues for aspiring HVAC professionals and their families to fund their education and acquire essential skills.

Another positive is that the bill makes Section 199A, the qualified business income (QBI) deduction, permanent and enhances its advantages. This affects HVAC contractors operating as S corporations, partnerships, and sole proprietorships, as they can continue to deduct up to 20% of their qualified business income.

The enhancement comes in the form of higher income thresholds before the deduction begins to phase out. The new phase-out begins at $75,000 for individuals and $150,000 for married couples filing jointly. This is an increase from the previous limits of $50,000 for individuals and $100,000 for married couples, meaning a greater number of HVAC contractors will be able to claim the full deduction.

Challenges for the HVAC Industry

A significant downside of the bill for the HVAC industry is the repeal of Section 25C and 25D tax incentives for projects starting after December 31, 2025. These residential tax incentives were instrumental in encouraging homeowners to invest in energy-efficient and clean energy improvements, thereby generating substantial business for HVAC contractors.

Section 25C, the energy efficiency home improvement credit, worth up to $3,200 annually for qualifying energy-efficient upgrades, was a key driver for the adoption of energy-efficient HVAC equipment. Section 25D, the residential clean energy credit, offered a 30% federal tax credit for geothermal heat pump installation. The discontinuation of these incentives could lead to a decrease in demand for these types of energy-efficient installations.

Another downside is that commercial HVAC tax incentives are also slated for a phase-out, albeit on a different timeline than the residential incentives. Sections 45L and 179D are set to expire for upgrades and projects starting after June 30, 2026.

Section 45L provides tax incentives to homebuilders and developers who construct or substantially reconstruct energy-efficient homes, while section 179D, enacted in 2005 and made permanent in 2020, allows the owners of commercial buildings to claim deductions for investing in high-efficiency HVAC systems, lighting, and building envelopes. This provision has been recognized for its role in fostering job growth and spurring innovation across the engineering, manufacturing, and construction sectors.
