TLDR

• Residential HVAC tax credits (Section 25C and 25D) ended after December 31, 2025, so homeowners won’t get federal rebates for 2026 upgrades.
• Businesses benefit from expanded Section 179 expensing and 100% bonus depreciation, allowing faster tax write-offs on HVAC equipment.
• Contractors and property managers should adjust sales strategies, budgeting, and replacement timing to reflect these new tax rules and focus on utility rebates and financing options.

Starting January 1, 2026, major federal tax credits for residential HVAC upgrades, including the 25C and 25D energy credits, will no longer apply to new installs. This change means homeowners cannot count on these federal incentives when buying heat pumps or other efficiency improvements next year. Meanwhile, businesses will see expanded benefits through 100% bonus depreciation and larger Section 179 expensing options. These shifts affect contractors, homeowners, and property managers by changing the financial outlook for HVAC projects starting in 2026.

Rules to know: credits ended, deductions expanded

"Placed in service" means your HVAC system must be installed and ready to use—not just bought—to qualify for tax benefits. Section 179 lets businesses deduct the full cost of qualifying equipment in the year they buy and use it. Bonus depreciation allows businesses to take a full deduction for equipment in the first year, speeding up tax savings. To qualify, keep important paperwork like AHRI certificates, model numbers, and the exact in-service dates on your invoices. These documents prove your system meets efficiency standards and when it was installed. Even though federal residential credits like Sections 25C and 25D have ended, state and utility rebates may still be available. So, saving your paperwork helps you claim those rebates and protects you if you get audited. Understanding these rules helps contractors, homeowners, and property managers plan purchases and tax strategies with confidence in 2026.

Sales, budgeting, and timing impacts

Contractors should update their sales approaches now that federal tax credits for residential HVAC upgrades have ended. Instead of focusing on the 25C credit, emphasize available utility rebates, ongoing energy savings, and flexible monthly payment plans. Homeowners will no longer get the 25C tax credit in 2026, so they need to rely more on local rebates, manufacturer promotions, and financing options to lower upfront costs. Property managers have a new advantage: they can use Section 179 expensing and 100% bonus depreciation to write off HVAC equipment faster. This makes it smart to plan replacements earlier, especially for failing units, to maximize these tax benefits and keep net operating income steady. Understanding these shifts can help everyone make better decisions on timing and budgeting for HVAC projects throughout 2026.

Spec choices that protect ROI in 2026

Right-sizing every job is key to protecting your return on investment this year. Use our Sizing Tool to make sure your system matches your space and needs perfectly. Efficiency ratings like SEER2 and HSPF2 measure cooling and heating performance, respectively. These must meet local program rules to qualify for rebates and savings. Consider using the Good–Better–Best tiers when selecting equipment. The Good tier offers essential features at a great value, Better adds improved efficiency and smart controls, and Best delivers top performance with advanced tech. For colder climates, heat pumps with higher HSPF2 ratings provide better winter heating, improving comfort and cutting costs. When shopping, focus on the right category: Heat Pumps, Air Conditioners, or Furnaces. Choosing the right equipment now helps you maximize savings and keeps your system running efficiently throughout 2026 and beyond.

What to do this quarter

Contractors should update their proposals and websites to remove any claims about the expired 25C credit. Instead, highlight available utility rebates and offer flexible payment plans to help customers manage costs. Access the Contractor Portal for updated tools and resources. Property managers need to consult with their CPA to understand how to use the expanded Section 179 expensing and 100% bonus depreciation for HVAC equipment. This can improve tax benefits and help adjust capital budgets and replacement schedules. Everyone should use the HVAC365 Sizing Tool to quickly find the right system for any job. For tax questions, always check with a qualified advisor to ensure compliance and maximize savings.
