How to Finance Energy Improvements Without the Federal Tax Credit
The Tax Credit Gap Is Real — But Manageable
Let's be direct about what was lost. The Section 25C Nonbusiness Energy Property Credit covered 30% of heat pumps, insulation, windows, and water heaters — up to $3,200 per year. The Section 25D Residential Clean Energy Credit covered 30% of solar installations with no cap. For a household doing a full electrification project, that could represent $8,000–$15,000 in federal tax benefits. That money is gone for installations beginning in 2026.
What remains is a patchwork of state credits, HOMES and HEAR rebates, utility incentives, and financing programs. The difference is that rebates come off the top of your project cost while tax credits only reduce your tax liability — meaning households with lower tax liability often couldn't fully capture the credits anyway. For many middle-income households, the rebate-focused 2026 landscape is actually better.
Start by calculating your rebate eligibility with the heat pump rebate calculator before exploring financing options — knowing what rebates reduce your out-of-pocket cost changes which financing product makes sense.
Option 1: PACE Financing
Property Assessed Clean Energy (PACE) financing is a lien attached to your property rather than a personal loan. You borrow against the value of the improvement and repay through your property tax bill. Three things make PACE attractive: no income requirements, loan terms up to 25 years, and the payment transfers with the home if you sell.
Ygrene, Renew Financial, and Dividend Finance are major PACE providers. Rates in 2026 run 6.5–9.9% APR — higher than traditional home equity financing but accessible to homeowners who don't qualify for HELOCs or who've already tapped their home equity. California, Florida, and Missouri have the most developed PACE markets. Check whether your county participates before counting on this option.
One significant caution: PACE loans are senior to mortgages in some states, which can complicate refinancing or selling. Read the lien position terms carefully. Some lenders won't approve a refinance on a PACE-encumbered property.
Option 2: State Green Banks
Several states have established green banks that provide below-market financing specifically for energy improvements. These aren't grants — they're loans — but the terms are often significantly better than private financing.
| State | Green Bank | Rate Range | Max Loan |
|---|---|---|---|
| Connecticut | CT Green Bank | 0–6.99% | $100,000 |
| New York | NY Green Bank / GJGNY | 0–6.5% | $25,000 |
| Maryland | MD Clean Energy Center | 3.5–7.5% | $20,000 |
| Rhode Island | RI Infrastructure Bank | 2.99–7% | $75,000 |
| Massachusetts | MassSave HEAT Loan | 0% | $25,000 |
Connecticut's Green Bank offers a 0% loan for households below 100% of AMI and market-rate loans for higher-income households. New York's Green Jobs Green New York (GJGNY) program offers unsecured loans for energy improvements — no home equity required. Massachusetts' HEAT Loan through MassSave is a 0% interest loan for up to $25,000 for efficiency improvements — one of the best financing deals in the country for homeowners in that state.
For Massachusetts residents, this 0% loan combined with Massachusetts energy rebates makes financing a complete electrification project genuinely affordable without touching retirement savings.
Option 3: Utility On-Bill Financing
Some utilities finance energy improvements and allow repayment through monthly utility bills. The appeal is simple: the energy savings often exceed the monthly payment, making the upgrade cash-flow positive from day one. Pacific Gas & Electric, Xcel Energy, and Duke Energy are among the larger utilities offering on-bill financing programs.
The catch is that on-bill financing typically covers a narrow range of improvements — usually ENERGY STAR appliances, insulation, and HVAC — and loan limits are often $5,000–$15,000. It won't finance a full $30,000 electrification project, but it works well for a targeted heat pump water heater installation or weatherization project.
Option 4: Home Equity Line of Credit (HELOC)
For homeowners with substantial equity built up during the pandemic housing boom, a HELOC at current rates (7.5–9.5% variable as of early 2026) offers flexible financing. Unlike PACE, HELOCs don't put a senior lien on the property. Unlike personal loans, interest on HELOCs used for home improvement may be deductible (consult a tax advisor — this depends on your specific situation).
The downside is that HELOC rates are variable and tied to the prime rate. If rates rise, your cost of capital rises with it. Fixed-rate home equity loans (HELOANs) provide certainty at slightly higher rates than variable HELOCs, typically 8–10%.
Option 5: Manufacturer and Installer Financing
Sunrun, Tesla, and several other solar installers offer their own financing products. Sunrun's $0-down solar lease has 25-year terms. Tesla's solar loan through various lending partners offers fixed rates. Sunnova offers similar structures.
For heat pumps, Mitsubishi's Diamond Dealer network and Carrier's dealer network offer manufacturer-backed financing, sometimes at promotional 0% rates for 12–18 months. After the promotional period, rates jump to 19–26% — so only use these if you can pay off the balance during the promotional window.
HVAC financing through contractors often routes through GreenSky, EnerBank (now Regions Energy), or Service Finance. These are legitimate products, but compare rates carefully. A "no payment for 12 months" offer that then carries 18.99% APR is not a good deal for a $15,000 heat pump installation if you're not paying it off.
Option 6: HEAR Program Rebates as Down Payment
High-Efficiency Electric Home Rebate Act (HEAR) rebates — up to $14,000 for income-qualified households — can function as an effective down payment, reducing the financed amount to something manageable with a personal loan or HELOC. The sequence matters: confirm rebate eligibility first, then use the expected rebate to calculate your financing need.
Some states are processing rebates as upfront discounts at the point of sale, meaning you never finance that amount at all. Check the current HEAR program guide for your state's rebate disbursement method.
What to Avoid
High-rate personal loans (above 12%) rarely make financial sense for energy improvements. The monthly interest cost can exceed the monthly energy savings for years. Similarly, zero-down solar leases from third-party owners lock you into 20–25 year contracts, complicate home sales, and often underperform the economics of owned systems with financing.
Contractor-arranged financing through referral partners often carries higher rates than you'd find shopping independently. Get a quote from your bank or credit union before accepting whatever financing the contractor offers.
Stacking Strategies
The best approach combines a low-rate financing product with available rebates and state programs. An example for a Colorado homeowner installing a heat pump:
- HOMES rebate (moderate income): $4,000
- HEAR rebate (income-qualified): $8,000
- Xcel Energy rebate: $1,500
- Colorado state rebate: $1,500
- Net cost after incentives: $7,000–$12,000 (down from $18,000–$22,000)
- Finance remainder via Colorado Energy Office green loan at 5.5%
At $10,000 financed over 10 years at 5.5%, monthly payment is $108. Monthly energy savings from replacing a gas furnace: typically $80–$180 depending on gas prices. The project can be cash-flow neutral to positive from day one.
Check the Colorado energy rebate page for current program availability and income limits before planning your project budget.
Credit Score Considerations for Energy Financing
PACE financing has no credit score requirement — it's secured by the property, not creditworthiness. Personal loans from banks and credit unions typically require a 680+ credit score for competitive rates. HELOCs and home equity loans require 700+ for the best rates and 80% or less loan-to-value. If your credit score limits your options, PACE or utility on-bill financing are the accessible alternatives.
Green bank loans from state programs (CT Green Bank, GJGNY in New York) often have more flexible underwriting than conventional loans because they're specifically designed to reach households that don't qualify for conventional financing. Credit unions in many areas offer energy improvement loans with rates 2–3 percentage points below banks for the same credit profile. Check your local credit union before assuming conventional bank terms are the market rate.
