A furnace or heat pump replacement is not a small purchase. Even a modest system upgrade in a Worcester County home can run several thousand dollars, and a full heat pump installation with weatherization work can reach well above $10,000 before incentives. For most households, paying that cost out of pocket all at once is not realistic, and it should not have to be.
Can I finance HVAC services in Massachusetts?
Massachusetts homeowners have several practical financing options for HVAC projects, ranging from a state-backed 0% interest loan program to contractor-arranged payment plans. Understanding what is available, how each option works, and how they can be combined with rebates will help you move forward with a necessary upgrade without putting unusual strain on your household budget.
What HVAC Financing Options Are Available in Massachusetts?
The Mass Save HEAT Loan: 0% Interest Financing Up to $25,000
The most financially advantageous option available to most Massachusetts homeowners is the Mass Save HEAT Loan. This is a 0% interest financing program backed by the state’s energy efficiency program and made available through participating local lenders. It allows eligible homeowners to borrow up to $25,000 for qualifying energy-efficient improvements and pay back only the principal, with no interest charges, over a term of up to seven years.
To put that in practical terms: if you finance $15,000 for a new heat pump system at 0% APR over seven years, your monthly payment would be approximately $179, and you would pay nothing beyond that $15,000 over the life of the loan. There are no hidden fees or deferred interest traps, which makes this a genuinely different product from most promotional financing offers in the home improvement market.
The HEAT Loan is available to customers of participating Massachusetts gas and electric utilities, including Eversource, National Grid, Cape Light Compact, Unitil, Berkshire Gas, and Liberty Utilities. Municipal electric customers may also be eligible if their home is heated with natural gas from a Mass Save sponsor utility. Approval is subject to standard lending criteria through a participating lender, so creditworthiness plays a role in whether you qualify.
Eligible improvements under the HEAT Loan include heat pump systems, heat pump water heaters, central air conditioning, insulation and air sealing, ductwork improvements, and certain other energy-efficiency upgrades. Standard furnace and boiler replacements may or may not qualify depending on specific program terms; the Mass Save website and your contractor can confirm eligibility for your specific project before you proceed.
The maximum loan amount of $25,000 applies over the lifetime of your eligible upgrades with a given account. Once you have financed improvements totaling that amount, additional measures generally cannot be added to the same cap. This is worth knowing if you are planning multiple upgrades over several years.
How Do You Apply for the HEAT Loan?
The application process has a few required steps that are worth understanding before you begin a project.
The first step is typically a no-cost Mass Save Home Energy Assessment. This is a professional evaluation of your home’s insulation, air sealing, heating and cooling equipment, and overall energy use. The assessment is free to qualifying Massachusetts homeowners and is often the gateway to accessing both rebates and HEAT Loan financing. It also produces a prioritized list of recommended improvements, which is useful for deciding which upgrades to tackle first.
After the assessment, you work with a participating contractor to get a proposal for the planned improvements. You then submit the HEAT Loan application to a participating lender, along with the signed contractor proposal. Once approved, you receive an authorization form before work begins. After installation, the loan is funded to cover the project cost, and you begin monthly repayment.
For Massachusetts homeowners, a number of participating banks and credit unions facilitate HEAT Loans. Your HVAC contractor may be able to refer you to lenders they have worked with, which can simplify the process.
Mass Save Rebates: Reducing What You Finance in the First Place
Financing and rebates work best when combined. For qualifying heat pump installations in 2026, Mass Save offers whole-home rebates of $2,650 per ton of capacity, up to a maximum of $8,500. Partial-home rebates are available at $1,125 per ton for homeowners who keep an existing fossil fuel system as backup. These rebates reduce the total project cost before financing is applied.
For example, a $20,000 whole-home heat pump installation that qualifies for an $8,500 Mass Save rebate leaves a net project cost of $11,500. Financed through the HEAT Loan at 0% over seven years, that works out to roughly $138 per month with no interest. For many Worcester County homeowners, that monthly figure is comparable to or less than their current monthly heating oil or propane cost, particularly given the efficiency advantages of modern cold-climate heat pump systems.
Smart thermostat upgrades, insulation, air sealing, and ductwork can also be bundled into the same HEAT Loan application, allowing you to address multiple improvements in a single financing arrangement.
What About Income-Eligible Households?
For households with income at or below 60% of the state median income, the Mass Save program offers significantly enhanced benefits that go beyond the standard rebate and loan structure. These can include no-cost heat pump installations, 100% coverage of insulation and air sealing work, and higher rebate caps. For households between 60 and 80% of the state median income, additional discounts may also be available.
If there is any chance your household qualifies under the income-eligible tier, it is worth confirming eligibility before proceeding with a project. The Mass Save website and your Home Energy Assessment provider can check this during the assessment process.
Contractor-Arranged Financing: What Is It and When Does It Make Sense?
Many HVAC contractors also offer their own financing arrangements through third-party lenders, most commonly through programs like GreenSky or Wells Fargo Home Projects. These are typically point-of-sale financing products that allow you to apply and receive a credit decision quickly, often during or immediately following the job estimate.
These programs offer several structures. The most commonly advertised is promotional 0% interest financing for a fixed period, typically 12 to 24 months, if the balance is paid in full before the promotion ends. This can be useful for homeowners who are confident they can pay off the balance within the promotional window and want to spread payments over several months without incurring interest.
There is an important distinction to understand with promotional financing: if the balance is not paid in full before the promotional period expires, deferred interest charges often apply retroactively from the original purchase date. This means you could owe months of accumulated interest at a high rate, sometimes 25 to 30% APR, on the original balance. This is very different from a true 0% loan like the HEAT Loan, where no interest accrues at any point. If you pursue contractor-arranged promotional financing, read the terms carefully and have a clear plan to pay off the balance before the promotional period ends.
Standard installment financing through contractor lenders is also available for homeowners who need longer terms or do not qualify for promotional offers. These carry interest, typically in the range of 8 to 20% APR depending on creditworthiness, and are a reasonable option when the HEAT Loan is not available for a specific type of work.
Contractor financing can also serve as a practical option for repairs rather than full system replacements. Emergency boiler repairs, furnace component replacements, and similar unplanned expenses are generally not eligible for the HEAT Loan, which is focused on energy-efficiency improvements. For those situations, a contractor’s financing program may be the most accessible way to manage a repair cost you were not expecting.
Can You Combine the HEAT Loan With Contractor Financing?
In most cases, the HEAT Loan covers the eligible portion of a project, and contractor financing would not be needed simultaneously. However, if your project includes both HEAT Loan-eligible improvements and additional work that falls outside the program’s scope, contractor financing could cover the remaining balance.
The most important thing is to understand what each financing source is covering before signing anything. Your HVAC contractor should be able to walk you through how the two interact for your specific project.
What If You Do Not Qualify for the HEAT Loan?
If your credit profile does not meet a participating lender’s requirements, or if the work you need does not qualify as an eligible improvement under the HEAT Loan program, you still have options.
Personal loans from your bank or credit union are worth exploring, particularly if you have an established relationship with a local financial institution. Massachusetts community banks and credit unions sometimes offer home improvement loan products with competitive rates.
Home equity financing, either a home equity loan or a home equity line of credit, can provide access to larger sums at rates lower than most personal loans or contractor financing products. This requires having meaningful equity in your home and goes through a more involved application process, but for a large HVAC project, it can be a cost-effective long-term financing approach.
For smaller repairs, a credit card with a 0% introductory APR period can spread a manageable balance over 12 to 18 months without interest, as long as the card is paid off before the promotional rate expires.
How Do I Get Started?
The most straightforward starting point for most Worcester County homeowners is scheduling a free Mass Save Home Energy Assessment. This costs nothing, takes a few hours, and opens the door to both rebates and HEAT Loan financing. It also gives you a clear picture of your home’s actual energy needs before you commit to a specific system or project scope.
From there, working with a qualified HVAC contractor who participates in the Mass Save program ensures that the equipment and installation meet program requirements, that rebate paperwork is handled correctly, and that you are not leaving money on the table.

A Summary of HVAC Financing Options in Massachusetts
For quick reference, here is how the main options compare:
The Mass Save HEAT Loan offers 0% interest, up to $25,000, terms up to 7 years, no deferred interest, and is best for qualifying energy-efficiency improvements including heat pumps, insulation, and air sealing. It requires a Home Energy Assessment and lender approval.
Contractor-arranged promotional financing (GreenSky, Wells Fargo Home Projects) offers 0% interest for a promotional period of 12 to 24 months, with deferred interest if not paid in full by the deadline. It is fast to apply, requires no separate assessment process, and is available for both qualifying improvements and standard repairs.
Standard installment financing through contractor lenders carries interest rates that vary by creditworthiness and is available for work that does not qualify for other programs.
Personal loans and home equity financing offer flexibility for any type of work, with rates and terms that depend on your credit profile and equity position.
Mass Save rebates apply regardless of how the project is financed and directly reduce the total amount you need to borrow. Applying both rebates and the HEAT Loan together produces the lowest total cost for most qualifying projects in Massachusetts.
