PA Energy Rebates for Exterior Upgrades (2026 Update)

What this means for Pennsylvania homeowners:

• Any qualifying product had to be "placed in service" (fully installed) on or before December 31, 2025 to be eligible. Simply paying a deposit or signing a contract before that date does not count.
• If you completed a qualifying project in 2022–2025, you can still claim the credit on the tax return for the year it was installed — see "How to claim a 2025 (or earlier) installation" below.
• For all new 2026 projects, focus on the still-available Pennsylvania state and utility programs described below, which remain a real way to lower your costs.

For homeowners claiming a 2022–2025 installation on a prior-year return: not every exterior product qualified for the Section 25C credit. Here is a breakdown of what did and did not qualify for homes in Pennsylvania (these criteria no longer apply to new 2026+ projects, since the credit has ended):

Windows and skylights ($600/year cap):

• Must meet Energy Star Most Efficient standards for your climate zone
• Zone 5 (Lehigh Valley): U-factor 0.25 or lower, SHGC 0.25 or lower for Most Efficient
• Zone 6 (Poconos): U-factor 0.22 or lower, SHGC 0.25 or lower for Most Efficient
• Credit applies to product cost only, not installation labor

• Must meet applicable Energy Star standards
• U-factor of 0.21 or lower for opaque doors, 0.26 or lower for doors with glass
• Includes entry doors, sliding glass doors, and storm doors that meet efficiency requirements

• Bulk insulation (fiberglass, cellulose, spray foam) that meets IECC prescriptive standards
• Air sealing materials including caulk, weatherstripping, and spray foam used for sealing
• Both product and labor costs qualify for insulation and air sealing

• Asphalt shingles and metal roofing that meet Energy Star requirements for solar reflectance and thermal emittance
• Qualifying products include cool-color asphalt shingles with solar reflectance of 0.25 or higher and standing seam metal roofing
• Not all roofing products qualify; check the Energy Star Certified Roof Products list

• Siding with integrated insulation that meets applicable energy code requirements may qualify
• The insulation component is the qualifying element, not the siding face itself

With the federal credit gone, Pennsylvania's state-level programs are now the primary incentives for exterior energy upgrades:

Act 129 Utility Rebate Programs: Pennsylvania's Act 129 requires electric utilities to fund energy efficiency programs for their customers. Rebates vary by utility and change periodically, but here are the major programs available in northeastern PA:

• PPL Electric Utilities (Lehigh Valley, parts of Poconos): Rebates for insulation, air sealing, and qualifying windows through their energy efficiency programs. Home energy audits often available at reduced cost or free
• Met-Ed (parts of Lehigh Valley and eastern PA): Similar rebate structure for insulation and weatherization improvements. Check FirstEnergy's Energizing Life program for current offers
• PECO (southeastern Lehigh Valley fringe areas): Rebates for insulation, smart thermostats, and energy-efficient equipment through their PECO Smart Ideas program

• Federally funded, state-administered program for income-qualifying households
• Covers insulation, air sealing, window repair or replacement, and heating system improvements at no cost to qualifying homeowners
• Income limits are typically 200% of the federal poverty level (roughly $60,000 for a family of four)
• Applied for through your local Community Action Agency

• Available in participating PA municipalities
• Finances energy improvements through a voluntary property tax assessment
• No upfront cost; repaid over 15-30 years through your property tax bill
• The assessment stays with the property if you sell

With the federal 25C credit gone for 2026, the smart play is to stack the state, utility, and financing options that are still available and time your project for the best contractor pricing. Here is how Pennsylvania homeowners can reduce the real cost of a major exterior renovation today:

1. Use Act 129 utility rebates (still active). PPL, Met-Ed, and PECO continue to offer rebates and discounted/free home energy audits for insulation, air sealing, and qualifying improvements. These are separate from any federal program and were not affected by the 2025 federal changes. Apply through your utility before work begins — see the section above.

2. Check income-qualified programs. The Weatherization Assistance Program covers insulation, air sealing, and some window work at no cost for qualifying households (roughly 200% of the federal poverty level). Applied for through your local Community Action Agency.

3. Finance strategically instead of waiting for a credit. Amero Exteriors offers financing from 6.99% APR with terms up to 12 years and 60-second pre-qualification that does not affect your credit. For energy upgrades, PACE financing (in participating municipalities) and FHA Title I home-improvement loans (up to $25,000, no equity required) are also worth comparing.

4. Time the work for value, not for a tax year. Because there is no longer a tax-year deadline to chase, you can schedule based on what actually saves money: book roofing and siding in the shoulder seasons (late fall / early spring) when crews have more availability, and bundle multiple services into one mobilization to reduce setup costs.

5. Prioritize the upgrades with the best standalone payback. Even without a credit, attic insulation/air sealing and high-efficiency windows still cut PA heating bills meaningfully every year — see our window and siding ROI guides for current numbers.

If you are claiming the credit for a project placed in service on or before December 31, 2025, proper documentation is essential. The IRS requires specific records, and missing paperwork can delay your refund or trigger an audit. Here is exactly what you need to keep:

Required documentation for each qualifying purchase:

• Manufacturer's certification statement - A written statement from the manufacturer confirming the product meets Section 25C energy efficiency requirements. Reputable manufacturers provide this on their website or with the product packaging. This is the single most important document
• Itemized receipt or invoice - Must clearly show the product cost separate from installation labor for windows and doors. For insulation and air sealing, the combined product-and-labor total is eligible
• Proof of installation date - The completion date determines which tax year the credit applies to. Your contractor's invoice or completion certificate serves this purpose
• Product specifications - Keep the NFRC label information for windows, R-value documentation for insulation, and Energy Star certification for roofing products

1. Complete IRS Form 5695 (Residential Energy Credits), Part II for Section 25C 2. Enter the total qualifying costs for each category (windows, doors, insulation, roofing) 3. The form calculates your credit based on the 30% rate and applicable caps 4. Transfer the credit amount to your Form 1040, where it reduces your tax liability 5. Attach Form 5695 to your tax return

Important filing tips:

• Keep all documentation for at least 7 years after filing
• If your work spanned multiple tax years (2022–2025), maintain a spreadsheet tracking which products were installed in which year and which credits you have claimed
• The credit is non-refundable, so if your tax liability is less than the credit amount, the excess is lost (it does not carry forward)
