Green Upgrades You Can Fund With a Home Equity Loan

Green upgrades can both help the environment and make your home more energy efficient. And if you’ve got equity built up, a home equity loan could help you fund those improvements.

Home equity loans let you tap into your built-up equity to fund everything from debt consolidation to home improvements, including green upgrades.

Those projects can be good for the environment and your budget: Green upgrades, energy savings and available tax credits or rebates may also be available to help offset part of the monthly payment.

Home Equity Loan Basics

A home equity loan gives homeowners access to a lump sum with a fixed interest rate that is often lower than the rate on a personal loan or credit card. That can make it easier to pay for major home upgrades that lower utility bills and may increase property value.

There are two main types of home equity loans: fixed-rate home equity loans and HELOCs.

A fixed-rate home equity loan gives you a one-time, lump-sum payout. They’re best for large, one-time expenses.

A home equity line of credit (HELOC) features flexible access to funds through a revolving credit line. They’re particularly useful for phased expenses, but also usually come with variable interest rates.

HELOCs and home equity loans generally come with lower rates than unsecured debt like personal loans, but also come with the caveat of being secured by your home equity.

Homeowners commonly use both HELOCs and home equity loans for home improvements, including green upgrades.

Here are a few common green upgrades you can fund with a home equity loan:

Solar Panels and Battery Storage

Solar panels and home battery systems can change a home's energy profile, but often come with a major upfront cost.

Keep in mind that the federal residential 30% credit for solar systems is now expired. It won’t apply to any systems placed in service after December 31, 2025.

Payback periods vary based on electricity prices, available incentives, system size, and how much energy your household uses.

Owned solar systems may also increase home value in some markets, according to SolarInsure.

Insulation and Air Sealing

Insulation and air sealing are often among the most cost-effective energy upgrades. These improvements help keep conditioned air inside the home, which can reduce heating and cooling demand and improve indoor comfort.

According to the U.S. Environmental Protection Agency ENERGY STAR program, air sealing and insulation upgrades can lower energy waste and improve overall efficiency, especially in older homes with attic, wall, crawl space, or duct leakage. That can translate to 11% to 15% in savings on annual energy costs.

For many homeowners, these upgrades offer a relatively quick payback period compared with larger systems like solar or geothermal equipment.

Heat Pump and HVAC Replacement

Heating and cooling make up a large part of a home’s energy use. Replacing an older furnace or air conditioner with a modern heat pump can reduce energy consumption and lower emissions, especially when paired with weatherization improvements.

Heat pumps move heat instead of generating it directly, which can make them much more efficient than traditional systems in many climates, according to the Rocky Mountain Institute. Air-source and geothermal heat pumps may also qualify for rebates or tax incentives.

Smart Thermostats

Smart thermostats and connected home controls can help reduce unnecessary heating and cooling use by adjusting a home’s temperature based on a household’s routine.

A smart thermostat can analyze your schedule and lower heat (or turn off your AC) when you’re away. That can translate to savings. According to ENERGY STAR, certified smart thermostats can help many households save on annual heating and cooling costs. If you add more controls like room sensors, automated shades, or occupancy-based systems, that can improve performance even more.

These products are usually lower-cost upgrades, which makes them a practical option for homeowners who want a relatively fast return on investment.

LED Lighting and Energy-Efficient Appliances

Replacing older lighting and appliances can deliver immediate energy savings. LED bulbs use substantially less electricity than incandescent bulbs and last much longer. ENERGY STAR-certified appliances can also reduce energy and water use, depending on the product category and the age of the item being replaced.

How much you can actually save depends on your usage habits, local electricity rates, and the model being replaced. Still, bundling several lower-cost upgrades into one home equity loan may help homeowners modernize more efficiently than financing each project separately.

Water-Efficient Fixtures

Green home upgrades are not limited to electricity use. Water-saving improvements such as WaterSense-labeled toilets, faucets, and showerheads can reduce water consumption and may also lower the energy needed to heat water.

These upgrades are usually less expensive than major HVAC or solar projects. When financed together with other home efficiency improvements, they may reduce your long-term water bill and utility costs.

How to Combine Incentives, Contractor Discounts, and Home Equity Financing

The federal 30% residential solar credit (Section 25D) has expired for systems installed after December 31, 2025. The Section 25C Energy Efficient Home Improvement Credit, which covered heat pumps, insulation, and other efficiency upgrades mentioned, also expired on the same date under the One Big Beautiful Bill Act.

Neither credit is available for property placed in service in 2026 or late, but there are still plenty of other incentives to doing green renovations on your home. The Database of State Incentives for Renewables & Efficiency (DSIRE) has a comprehensive list of both state and federal incentives.

Combining federal and state incentives, along with contractor promotions, can help lower the total cost of your project.

The Bottom Line

Projects like solar panels, insulation, heat pumps, efficient appliances, and water-saving fixtures can lower utility costs. Home equity loans can be a smart way to fund those improvements.

Frequently Asked Questions About Funding Green Upgrades With a Home Equity Loan

What qualifies as a green upgrade for a home equity loan?

Green upgrades generally include home improvements that reduce energy or water use. Examples include insulation, heat pumps, solar panels, smart thermostats, efficient appliances, and low-flow plumbing fixtures.

Is a home equity loan a good way to finance green home improvements?

It can be. A home equity loan may offer lower rates than unsecured borrowing options, and fixed payments can make budgeting easier for larger one-time projects.

What are the benefits and risks of using a home equity loan for green upgrades?

Potential benefits include lower rates, predictable monthly payments, and possible added home value. The main risk is that your home serves as collateral, so it is important to borrow within a manageable range.

How does a home equity loan compare with other financing options for green projects?

A home equity loan is often best for larger projects with known upfront costs. A HELOC may work better for phased renovations, while personal loans may close faster but often come with higher rates.

Is home equity loan interest tax deductible for green upgrades?

It may be, if the loan proceeds are used to buy, build, or substantially improve the home that secures the loan. Tax treatment depends on individual circumstances, so homeowners should consult a qualified tax professional.
