HVAC Tax Credits + Rebates — Frequently Asked Questions

• What is the federal 25C tax credit and how much can I get for an HVAC install?

  The federal 25C Energy Efficient Home Improvement Credit (Inflation Reduction Act, 2023-2032) covers 30% of qualifying HVAC installation costs up to specific annual caps: up to $2,000 per year for qualifying high-efficiency heat pumps (including ductless mini-split heat pumps and geothermal heat pumps when claimed under 25C), and up to $1,200 per year combined for central air conditioners, gas furnaces, electric furnaces, oil furnaces, hot water boilers, and home-envelope improvements like insulation, exterior doors, and windows. The cap is an annual cap that resets each tax year, so a heat pump install in 2026 plus an envelope upgrade in 2027 can both claim the credit.
• Does my heat pump or AC actually qualify for the 25C credit?

  Qualification depends on equipment efficiency tier. For heat pumps, the equipment must meet the Consortium for Energy Efficiency (CEE) highest published efficiency tier in effect at the time of installation, which currently means specific SEER2, EER2, and HSPF2 thresholds that vary by climate region (Baldwin County is in CEE's South region). For central air conditioners and furnaces under the $1,200 cap, similar CEE thresholds apply. Air Solutions provides the AHRI certification statement and equipment specifications at install — your tax preparer files IRS Form 5695 with your federal return. We do not give tax advice, but we provide the documentation your CPA needs.
• What is the 25D Residential Clean Energy Credit, and how is it different from 25C?

  The federal 25D credit covers 30% of cost — with NO annual cap — for solar electric, solar water heating, geothermal heat pumps, fuel cells, and battery storage. Geothermal heat pumps qualify under 25D rather than 25C, which is significant: a $30,000 geothermal install can claim a $9,000 credit under 25D versus the $2,000 cap under 25C. The 30% rate runs through 2032 and steps down in 2033-2034. Air-source heat pumps (the dominant Baldwin County install) qualify under 25C, not 25D.
• What Alabama Power rebates apply to a Baldwin County HVAC install?

  Alabama Power runs a Smart Neighbor heat pump rebate program for residential customers in Alabama Power service territory. Rebates typically range from $200-$500 per qualifying heat pump install depending on equipment efficiency and program year; rates are subject to change and the program can be paused without notice. Air Solutions submits the rebate paperwork on your behalf when the program is active and your equipment qualifies. Most of Baldwin County is Alabama Power territory; a small fraction of Daphne and Spanish Fort residents are on Riviera Utilities or Baldwin EMC and need to check with their utility for separate rebate programs.
• Can I stack the federal 25C credit, the Alabama Power rebate, and HVAC financing on the same install?

  Yes — they are independent programs and they stack. A typical Baldwin County heat pump install might claim a $2,000 federal 25C credit on the federal tax return, a $300 Alabama Power Smart Neighbor rebate at install (we file the paperwork), and use HVAC financing to spread the remaining cost over monthly payments. All three reduce the effective cash cost. We bring the actual stacked-numbers projection to the in-home consultation so you see the math against your specific equipment quote, not a brochure default.
• How do I claim the 25C credit on my taxes?

  You claim the credit by filing IRS Form 5695 (Residential Energy Credits) with your federal tax return for the year the equipment was placed in service. We provide the manufacturer's certification statement, the AHRI certificate, and the equipment specs at the time of install — keep these with your tax records. The credit is non-refundable, which means it reduces your federal tax liability dollar-for-dollar but cannot generate a refund larger than your tax owed. Excess credit cannot be carried forward to future years under current rules. A CPA or tax preparer is the right person to confirm your specific situation; we do not give tax advice.
• Do manufacturer rebates apply on top of all of that?

  Sometimes. Major HVAC manufacturers (Trane, Carrier, Lennox, Rheem, Bryant, Daikin, Mitsubishi) run periodic seasonal rebates ranging from $50 to $1,500 depending on equipment tier and the active promotional period. These vary by quarter, sometimes by month, and require that the equipment be installed by an authorized dealer (Air Solutions is authorized for the major brands). When a manufacturer rebate is active and the equipment qualifies, we apply it at quote and submit the documentation directly. Manufacturer rebates stack on top of federal 25C and Alabama Power rebates — they are separate programs.
• Are there HVAC tax credits or rebates for commercial properties?

  Yes. Section 179D is the federal commercial energy-efficient building deduction (up to $5/sq ft for buildings meeting specific efficiency improvements). Section 179 (different from 179D) is the standard small-business equipment deduction that covers commercial HVAC capital equipment expensed in the year of install. Commercial heat pump installations may also qualify for the federal Investment Tax Credit (ITC) under specific provisions of the Inflation Reduction Act. We provide the install documentation in the format your CPA needs; we do not file commercial returns or give business tax advice.
