DC Energy Rebates 2026: Roof, HVAC & Water Heaters

The Big Picture: Federal, State, and Local Incentives in 2026

For DMV homeowners, energy incentives have come in three layers: federal tax credits, state or utility rebates, and sometimes manufacturer deals. For 2026, the main federal layer is gone: the 25C credit ended for improvements placed in service after December 31, 2025. That leaves state, utility, and manufacturer programs, and you have to understand how each one pays out to budget right.

The 25C credit worked as a tax credit: you lowered what you owed on your federal income taxes for the year you did the project. Local programs from the DC Sustainable Energy Utility (DCSEU), Dominion Energy, or Pepco work differently, typically as an instant discount or a check after the job's finished, and eligibility can depend on income. Their terms change, so confirm the current details with the program administrator.

Manufacturer promotions are worth a look, too. Check Bradford White's and Rinnai's websites for any current offer on the specific model you're considering. Research state, local, and manufacturer options before you sign a contract for any big upgrade.

• Federal (25C): Ended for improvements placed in service after December 31, 2025; it does not apply to 2026 projects.
• State/Local (DCSEU, Pepco, Dominion, Virginia HEAR/HOMES): Check current status, amounts, and eligibility with each program administrator.
• Manufacturer: Check Rinnai's or Bradford White's websites for any current promotion.
• Strategy: Confirm eligibility for all three incentive types before buying to pick a qualifying model and maximize savings.

The Federal 25C Credit: What Ended After 2025

The main federal incentive was the Energy Efficient Home Improvement Credit (25C), expanded by the Inflation Reduction Act. It was the source of the '$2,000 heat pump tax credit': 30% of qualifying project costs, with yearly caps by equipment type. Under the One Big Beautiful Bill Act, the IRS says the credit is not available for property placed in service after December 31, 2025.

If your heat pump or heat pump water heater was placed in service in 2025 or earlier, you may still be able to claim the credit for that tax year, within its caps. Equipment installed in 2026 does not qualify. Remember, it was a non-refundable tax credit, not cash back, so talk to a tax professional about your own situation.

The credit also covered high-efficiency gas tankless and other water heaters, electrical panel upgrades, and insulation and air sealing, with lower caps: up to $600 for a qualifying water heater or panel upgrade, up to $1,200 for insulation and air sealing, and roughly $3,200 in total per year. Those caps applied through 2025; none of them apply to 2026 projects.

• Heat Pumps & HPWHs: Was 30% of cost, up to $2,000 a year; ended for improvements placed in service after December 31, 2025.
• Efficient Water Heaters (Tank/Tankless): Was 30% of cost, up to $600 a year; ended after 2025.
• Weatherization (Insulation & Air Sealing): Was 30% of cost, up to $1,200 a year; ended after 2025.
• Electrical Panel Upgrades: Was 30% of cost, up to $600 a year with another qualifying upgrade; ended after 2025.
• Note: These limits applied through 2025 only. Confirm your situation with the IRS and your tax advisor.

D.C. Rebates: DCSEU, Lead-Free DC & Electrification

If you live in the District of Columbia, the DC Sustainable Energy Utility (DCSEU) is the main place to check for local energy programs for homeowners and landlords. Its offerings, including any heat pump incentives and any income-based tiers, change over time, so confirm current programs, amounts, and eligibility directly with DCSEU. With the federal 25C credit gone for 2026 projects, there's no federal credit to stack them with.

People also ask about DCSEU incentives for ENERGY STAR® certified appliances like refrigerators, clothes washers, and dehumidifiers, including the D.C. dehumidifier rebate. Check DCSEU for whether these are currently offered and at what amount. Ask, too, whether a whole-home program that starts with a discounted energy audit is available; an audit maps out a plan for your house either way.

Some health-and-safety programs overlap with renovation work. DC Water's Lead Free DC program focuses on replacing lead water service lines, which is licensed plumbing work. Under its block-by-block program, District funding covers private-side replacement at no cost to residents, regardless of income; DC Water contacts owners when their block is scheduled, and DOEE offers discounted assistance outside block projects. Check DC Water's construction dashboard before you pay for private-side work. If you're planning a big renovation, find out when your block is scheduled so the rest of the work can be timed around it.

• Heat Pumps: Check DCSEU for any current heat pump program; the $2,000 federal credit ended after 2025.
• Water Heaters: Ask DCSEU or your utility whether any current program covers heat pump or gas tankless models (e.g., Rinnai).
• Appliance Rebates: Check the DCSEU website for current deals on dehumidifiers, smart thermostats, and other ENERGY STAR® appliances.
• Lead Free DC: DC Water's block-by-block program replaces private-side lead service lines at no cost to residents; check its construction dashboard.

Virginia: Utility and State Rebate Programs

In our Northern Virginia service areas—Arlington, Alexandria, and Fairfax County—local incentives come mainly from your utility company and from state-run programs such as Virginia's HEAR and HOMES rebates. It's not like D.C., which has the central DCSEU. Your eligibility depends on who your electric and gas provider is, so check their websites, and the state program administrator, for current info.

Dominion Energy is the main electric utility in Northern Virginia. Check its website for the current status of any program covering energy audits, insulation, air sealing, ductwork, heat pumps, or smart thermostats. Programs like these usually ask for an online application with your contractor's itemized invoices.

Pepco is the electric utility in the District. Like Dominion, its program offerings change, so check its website for anything currently available for ENERGY STAR® appliances, lighting, or high-efficiency HVAC. Wherever you live, your utility company's website and the program administrator are the first places to check.

• Virginia (Dominion Energy): Check their site for current rebates on heat pumps, energy check-ups, duct work, and insulation.
• D.C. (Pepco): Check its site for any current program on HVAC, ENERGY STAR appliances, or lighting.
• Virginia (HEAR/HOMES): Check the state program administrator for current status and eligibility.
• First Step: Identify your electric and gas provider. Their website has the official rebate info for D.C. and Virginia.

Roofing and Insulation Rebates

Direct 'roof rebates' are rare. The federal weatherization credit (25C), which covered attic insulation and air sealing at 30% up to $1,200 a year, ended for improvements placed in service after December 31, 2025. A roof replacement is still the best time to upgrade attic insulation and seal air leaks, because sealing up the house—the 'building envelope'—is just as important for saving energy as the furnace or AC.

Washington D.C. has had programs for 'cool roofs' in the past. These use reflective materials that bounce sunlight and heat away from the building. This lowers cooling bills and helps cool down the city. The funding for these rebates changes, so it’s always a good idea to check with the DC Department of Energy & Environment (DOEE) or the DCSEU to see what's available, especially for bigger buildings.

For our customers in historic D.C. neighborhoods like Georgetown, Capitol Hill, and Dupont Circle, choosing materials is about following the rules, not just efficiency. The Historic Preservation Review Board (HPRB) has strict guidelines for roofing materials to protect the look of these old neighborhoods. We plan the HPRB review into the project and can help you pick roofing and insulation that is both right for your historic house and as energy-efficient as possible.

• Federal Tax Credit: The 30% insulation and air-sealing credit (up to $1,200) ended after 2025; the upgrade is still best done during a roof replacement.
• Cool Roofs: Check for D.C. rebates on reflective roofing materials that cut summer cooling costs.
• Historic Districts: Use a contractor who knows HPRB rules to balance efficiency with historic guidelines.

Maximizing Savings on Water Heaters: Tankless vs. Heat Pump Models

Heating water is a big part of your energy bill, so an efficient water heater pays you back every month. The two most efficient types are electric heat pump water heaters (HPWHs) and high-efficiency gas tankless models. In Northern Virginia, we're an authorized Rinnai (tankless) and Bradford White (tank) installer, so we can walk you through the pros and cons of each.

Heat pump water heaters are extremely efficient. They work like a refrigerator in reverse, pulling heat from the air and putting it into the water. They can be three to four times more efficient than a standard electric tank. That efficiency is why they drew the biggest incentives. The $2,000 federal credit for them ended for improvements placed in service after December 31, 2025; check with DCSEU or your utility for any current local program.

Gas tankless water heaters, like the Rinnai units we install, have their own advantages. You get endless hot water, they take up less space, and they last a long time—some sources say 20 years or more. The most efficient condensing models qualified for the federal tax credit (up to $600) through 2025; for 2026, check your gas utility for any current program. If you already have gas lines and want on-demand hot water, a tankless unit is a strong option. For efficient Bradford White tank models, ask your utility whether any ENERGY STAR program currently applies.

• Heat Pump Water Heaters (HPWH): Highest efficiency. The $2,000 federal credit ended after 2025; check local programs.
• Tankless Gas Water Heaters (Rinnai): Great performance, saves space, long life. Check your gas utility for any current program.
• Efficient Tank Water Heaters (Bradford White): Reliable, lower upfront cost. Ask your utility about any current ENERGY STAR program.
• Installation Note: Upgrading may require new electrical, venting, or gas lines. A qualified contractor can assess the work needed.

Landlords: Rebates, TOPA & Compliance

As a property management contractor, we know landlords and multi-family building owners have different needs for energy upgrades. Ask DCSEU, Pepco, and Dominion Energy whether any current program covers multi-family buildings, such as common area lighting, central boilers and water heaters, windows, or individual apartment HVAC systems.

Upgrading old systems before they break is just smart business. You avoid expensive urgent repairs, get fewer tenant complaints, and make your property look better to new renters. In D.C., you have to keep your property safe and habitable to have a Basic Business License (BBL) for rentals. Putting in a new, reliable HVAC or plumbing system helps you meet your legal duties. Lower utility bills from these upgrades are also a great feature to advertise to tenants.

If you're a landlord thinking about selling, these upgrades can matter in the Tenant Opportunity to Purchase Act (TOPA) process in D.C. Proof of capital improvements can affect the property's value and sale price. In Virginia, new zoning laws like SB 531 will encourage Accessory Dwelling Units (ADUs) by 2027. If you plan to build and rent out a new unit, you should build it with high-efficiency systems from day one. This is all general information, not legal advice, so be sure to check the current rules with the right D.C. or Virginia authorities.

• Multi-Family Programs: Check with DCSEU and utilities for rebates designed for apartment buildings and condos.
• Proactive Maintenance: Replace old systems before they fail. It improves tenant satisfaction and saves you money.
• Compliance: Upgrades help with BBL compliance and can be a factor in TOPA. (This is not legal advice).
• ADU Construction (VA): Building a new rental unit? Plan for high-efficiency systems to lower operating costs.

Rebate Application Checklist

Applying for energy rebates can feel complicated, but a simple checklist makes it easier. The number one rule is to do your research before you buy. Rebate programs have specific efficiency requirements (like SEER2, EER2, or UEF ratings). Buying the wrong model is an expensive mistake. The order you do things in matters if you want to get your money.

Your contractor is your best ally here. A good, licensed contractor knows how to install the equipment right and which models qualify for which rebates. They will give you the paperwork you need for your applications. This includes itemized invoices with exact make and model numbers, and technical sheets like the AHRI Certificate that proves the system's efficiency.

Keep a good folder—digital and paper—for every project. It should have the proposal, the final invoice, pictures of the model and serial number plates on the equipment, spec sheets, and copies of your rebate applications. For a federal credit on equipment installed in 2025 or earlier, you don't send this paperwork in with your tax return, but you have to keep it in case you get audited. For local rebates, you will have to send copies of these documents with your application.

• Step 1: Research & Verify. Before work starts, check the DCSEU, utility, and state program websites for current rebate amounts and equipment rules.
• Step 2: Get Quotes. Choose a licensed, insured contractor who knows local rebate programs and can guide you on qualifying equipment.
• Step 3: Select Equipment. Work with your contractor to pick a system that meets the efficiency ratings for your targeted rebates.
• Step 4: Install. Have the equipment installed to code by your licensed contractor.
• Step 5: Gather Paperwork. Get the final paid invoice, AHRI certificate (for HVAC), and other required documents from your contractor.
• Step 6: Apply. Submit any local rebate application quickly; the federal 25C credit on IRS Form 5695 covers only equipment placed in service through 2025.
