Can I claim 25C every year?

You can. Annual caps reset with each tax year. Install a heat pump in 2026 (claim $2,000) and a high-efficiency furnace in 2027 (claim $600), and the credit applies in both filing years.

Does the 25C credit cover installation labor?

It does. The credit applies to both equipment and professional installation expenses. The 30% is calculated on the complete invoice, not just the hardware portion.

My CPA hasn't heard of the 25C changes — what do I tell them?

Point them to the IRS Form 5695 instructions (revised for the Inflation Reduction Act) and the ENERGY STAR federal tax credit page. The updated 25C provisions became effective January 1, 2023, and extend through December 31, 2032.

Professional 25C Tax Credit for HVAC — Up to $2,000 Back in Asheville & Western NC

The Most Accessible Federal HVAC Incentive

The Energy Efficient Home Improvement Credit (Section 25C of the Internal Revenue Code, overhauled by the Inflation Reduction Act) represents the easiest federal money for WNC homeowners upgrading HVAC equipment. It reimburses 30% of qualifying equipment and labor costs up to yearly caps, and it renews every tax year through 2032. You do not need to be a tax professional to take advantage of it.

The Dollar Amounts

Heat pumps (air-source, ground-source, or ductless): 30% of cost, capped at $2,000/year — the single richest residential HVAC incentive on the books. Central air conditioners (meeting efficiency thresholds): 30% of cost, capped at $600/year. Gas furnaces (97%+ AFUE): 30% of cost, capped at $600/year. Key detail: The $2,000 heat pump ceiling and the $600 AC/furnace ceiling are independent annual limits. Installing a qualifying heat pump AND a qualifying furnace in one year opens the door to as much as $2,600 in combined credits.

2026 Eligibility Requirements

Not every HVAC unit qualifies — the equipment must clear specific efficiency bars. Air-source heat pumps: SEER2 ≥ 16, HSPF2 ≥ 8.1, EER2 ≥ 12. Central ACs: SEER2 ≥ 16 (split systems), ≥ 15.2 (single package). Gas furnaces: AFUE ≥ 97%. The product must also carry certification from an AHRI-listed manufacturer. Quality Mechanical selects qualifying equipment for every eligible project and provides the manufacturer certification documentation with each installation.

How to Claim It, Step by Step

Step 1: Have qualifying HVAC equipment installed (we take care of this). Step 2: Hold on to your installation invoice and the manufacturer's certification statement (we furnish this). Step 3: Complete IRS Form 5695 (Residential Energy Credits) at tax time. Step 4: Carry the credit amount over to your Form 1040, directly reducing your tax bill. The credit is non-refundable — it lowers what you owe but cannot produce a refund below zero. Speak with your tax advisor about your individual circumstances.
