Section 179D of the Internal Revenue Code allows building owners and contractors to claim a tax deduction up to $1.88 per square foot (as of 2024) for commercial building energy-efficient property, including HVAC systems. This deduction reduces taxable income for properties meeting energy efficiency standards, providing substantial tax incentives for upgrading to high-efficiency heating and cooling systems.
Eligibility Requirements
Section 179D applies to new commercial buildings or major renovations that reduce energy costs by at least 50% compared to baseline standards set by ASHRAE 90.1-2007. HVAC upgrades contributing to this energy reduction qualify for the deduction. Building owners, design professionals, and contractors can claim the benefit, though eligibility rules vary. The deduction is available for properties placed in service after December 31, 2022, through December 31, 2032, under current law.
Financial Impact
A typical 50,000 square-foot commercial building could claim deductions of $94,000 or more for comprehensive energy upgrades. The deduction reduces federal income taxes dollar-for-dollar (within limitation rules). Building owners should work with tax professionals and energy consultants to ensure compliance with documentation requirements and to maximize the deduction benefits available for their HVAC renovation projects.
