How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- This is a companies list: these are the lenders and platforms behind the financing your HVAC contractor offers at the kitchen table.
- The sticker APR is not the whole price. Dealer fees of several percent are commonly baked into the quote, and deferred interest plans charge back every cent of interest if a balance survives the promo window.
- Wisetack publishes an APR range of 0 to 35.9 percent, Hearth shops your application across lending partners from about 7.99 percent, and GreenSky is the largest platform in US home improvement lending.
- Compare the financing against a bank loan or home equity line before you sign. On a $12,000 system, five points of APR over ten years is thousands.

The best HVAC financing companies in 2026

GreenSky is the name behind more HVAC financing offers than any other in the US, now owned by a Sixth Street led consortium after Goldman Sachs sold it in 2024. Its model is a menu of plans the contractor picks from: reduced rate loans, reported around 6 to 12 percent for strong credit, and deferred interest promotions of six to twenty four months.
The deferred interest plans are where GreenSky deals go wrong. Interest builds quietly during the no interest window at rates reported between about 18 and 27 percent, and if any balance remains when the window closes, all of it is charged. Get the plan code, the exact payoff deadline and the deferred rate in writing, and only take it if the payoff is certain, not hopeful.
What we like- The largest home improvement lending platform in the US, loans and credit lines reported up to $100,000 for big projects, a deep bench of promotional and reduced rate plans, offered by a large share of national HVAC firms
Watch out for- Its deferred interest promotions accrue interest during the promo period that lands in full if you miss payoff, underwriting tightened under recent ownership and approval rates for mid range credit fell, terms differ by plan code, which most homeowners never see explained

Wisetack is the newer platform small and mid size HVAC shops adopted fastest, because a technician can text you an application and show real offers before leaving the driveway. The prequalification is a soft pull, so checking costs nothing, and the offers show actual APRs for your credit rather than a teaser.
Its honesty about the range cuts both ways. Zero percent exists for excellent credit on shorter terms; 35.9 percent is what weaker credit can be offered, and a loan at that rate roughly doubles a system's cost over a long term. If Wisetack's offer lands high, treat it as information, not obligation: your credit union prices the same file differently.
What we like- Publishes its consumer APR range openly at 0 to 35.9 percent, soft credit pull prequalification with a decision in about a minute by text link, no prepayment penalties and no hidden fees in its pitch, a flat per transaction merchant fee model that smaller contractors can join without enrolment costs
Watch out for- The top of that APR range is expensive money, less firepower on the very large subsidised promotions that close $15,000 plus replacements, contractor fees rise on promotional plans and can surface in your quote, loan sizes suit service work and mid range installs best

Hearth is a marketplace wearing a contractor tool's clothes. The contractor sends one link; lending partners compete inside it; you see a row of real offers with rates reported from about 7.99 percent for strong credit. That structure is the friendliest in this list, because comparison is the only reliable defence against a bad rate and Hearth builds it into a single application.
Its flat subscription pricing for contractors, reported between about $1,500 and $5,000 a year, also matters to you indirectly: a contractor who is not paying a per loan dealer fee has less reason to steer you to the plan that pays them rather than the plan that suits you. Still read each partner offer's full terms; the marketplace shows the menu, it does not order for you.
What we like- One soft pull application returns offers from a network of lending partners, loans reported from $1,000 to $250,000 with terms up to twelve years, its own material says scores down to about 550 can be served, contractors pay a flat subscription rather than a per loan dealer fee, which removes one markup motive
Watch out for- You are matched to partners, so final terms are the partner's, not Hearth's, advertised from rates apply to the strongest files only, the contractor's subscription model suits firms that finance often, the offer spread can still top out near 36 percent for weak credit

Service Finance is one of the old guard of home improvement dealer lending: the contractor is the customer, you are the borrower, and the product is a straightforward fixed rate loan for the job. That structure lacks the marketplace comparison of Hearth but often delivers the lowest straightforward APR in the room for a borrower with good credit and a long term.
Because the programme is the dealer's, two neighbours financing the same system through different contractors can be offered different Service Finance terms. Ask which plan you are on, whether it carries deferred interest, and what the rate becomes if it does. A fixed rate loan with no deferred interest clause is the cleanest product in this category when the APR is fair.
What we like- A long established dealer lender owned within the ECN Capital group, fixed rate installment loans with reported ranges around 7 to 18 percent for qualified borrowers, long terms that suit full system replacements, no interest and reduced rate plans for dealers who want them
Watch out for- Available only through its dealer network, terms and approval depend on the contractor's programme, promotional structures vary, so paperwork reading is on you, less visible to consumers, which makes independent reviews thinner

Foundation Finance exists for the kitchen table moment when the first application says no. Its dealers use it as the second look: the lender willing to price a thinner or bruised credit file that GreenSky or Service Finance declined. For a household with no heat and no savings, an approval at a high rate can still be the right emergency decision, taken with open eyes.Open eyes means doing the total cost sum before signing, not after. A $10,000 system at a subprime APR over ten years can cost close to double in total payments. Compare a smaller repair that buys a season, and a utility or state energy loan if your state runs one, before the second look becomes the only look.
What we like- Known for second look approvals when a prime lender has declined the application, works through dealers across home improvement including HVAC, offers revolving and installment options, gives contractors a route to serve customers the big platforms turn away
Watch out for- Weaker credit pricing means higher APRs, and the totals can be severe over long terms, dealer fees on subprime plans are among the highest and land in your price, terms vary widely by dealer programme

EnerBank has financed home improvements through contractors for decades and now sits inside Regions Bank, which gives its loans a plain bank character: fixed rates, fixed terms, and promotional structures that tend to be true same as cash offers rather than deferred interest traps. Confirm that on your own paperwork, because the plan in front of you is the only one that counts.
For borrowers, EnerBank is often the quote that looks boring and ages best: no app theatrics, just a rate and a term. If your contractor offers it beside a flashier promotion, price the promotion's failure case, the one where a payment is late in month eleven, before deciding the boring loan is worse.
What we like- A bank lender, now part of Regions Bank, specialising in home improvement loans through contractors, fixed rate loans with reported ranges around 8 to 20 percent, same as cash and reduced rate loan structures that are plainer than deferred interest cards, a long record in the dealer channel
Watch out for- Only available through participating contractors, promotional same as cash plans still need the fine print read, rates for weaker credit sit at the top of the range, consumer facing information is thinner than the fintech rivals

Synchrony is the financial engine inside a large share of store and dealer financing in America, and its home improvement offers typically arrive as a credit account with a promotional period. Used perfectly, paying the balance inside the window, it can be the cheapest money on this page.
The business model, however, is built on accounts that do not pay in the window. Deferred interest at card APRs in the high twenties turns a discounted system into an expensive one quickly, and revolving balances invite minimum payments that guarantee the window is missed. If a Synchrony promotion is your plan, set the payoff schedule the day the system is installed, in automatic payments, with a month to spare.
What we like- One of the largest US consumer credit issuers, behind many retailer and dealer financing programmes, promotional periods are common across its home improvement network, established servicing and payment infrastructure
Watch out for- Much of its home improvement financing runs on revolving credit with deferred interest terms, post promotion APRs reported around 27 to 30 percent, a credit card balance is easier to let linger than a closed installment loan, terms depend entirely on the merchant programme

Sunbit made its name financing car repairs and dental bills at the moment of need, and now offers the same pattern to home services customers: a quick application, a soft pull, and payment options for a repair or modest job. For a $1,500 compressor repair in August, that speed is the entire point.
Its place here is the small end. A full system replacement deserves the fuller comparison above. And the general rule holds: an approval is not a recommendation. Read the APR and the total of payments, which its screens do show, and decide with the whole number in view.
What we like- Built its name on fast, soft pull approvals at the point of need, high approval rates across credit bands are its core claim, monthly payment offers for repairs and smaller jobs where a full loan process is overkill, transparent offer screens before you commit
Watch out for- Smaller ticket focus means big replacements may exceed its sweet spot, high approval rates pair with high APRs at the weaker end, home services is a newer field for it than its auto repair base, total cost on long terms still needs the same hard look
How we chose
We listed the financing companies a US homeowner is most likely to meet through an HVAC contractor in 2026, covering the big platform, the marketplace, the dealer lenders, the second look lender and the point of need services. We checked current comparisons for APR ranges, fee models and programme structures, and treated every published rate as a range with a credit condition attached, because that is what it is. One well known lender was excluded because it went through Chapter 11 in 2025 and its consumer lending future is unsettled. We did not claim hands-on testing and did not apply for any loan; figures here are reported ranges to argue with, not quotes.
How to finance a new HVAC system without overpaying
Price the credit separately from the system. Get the cash price of the job in writing first. Then price the financing. Bundled into one monthly figure, the dealer fee and interest hide inside a payment that sounds manageable while the total grows by thousands.
Interrogate any no interest offer with one question: is it deferred interest or true promotional APR? On a true promotion, interest simply does not accrue during the window. On deferred interest, it accrues from day one at a high rate and lands in full if a balance remains. The answer is in the plan documents, and a salesperson who cannot produce them has answered for you.
Bring an outside quote to the table. A credit union personal loan, a bank home improvement loan, or a home equity line for larger jobs often undercuts dealer financing for good credit, and marketplaces exist precisely because rates for the same borrower vary by lender. The contractor's offer wins some comparisons honestly; make it win, not inherit, the job.
Match the term to the equipment, and the payment to the worst month. A loan should end before the system does, and long terms at high APRs can double a price. If the payment only works in a good month, the repair instead of replace conversation, a utility rebate, or a state energy programme belongs back on the table.
Frequently asked questions
What APR should I expect on HVAC financing?
Strong credit borrowers see offers from about 6 to 12 percent on fixed rate dealer loans and marketplace offers from about 8 percent. Mid range credit lands in the teens. Weaker credit can be quoted 25 to 36 percent, where total interest over a long term can approach the price of the system itself, which is why comparing lenders matters more than comparing monthly payments.
What is a dealer fee and why should I care?
The lender charges your contractor a percentage of the job, often several percent and higher on promotional plans, for offering you attractive terms. Contractors recover it in the job price, so cash and financed customers may be quoted different totals for the same system. Asking for the cash price exposes it.
Is 0 percent HVAC financing ever a good idea?
Yes, in two cases: a true promotional APR you are certain to clear inside the window, or a reduced rate plan where the interest saving beats any price markup for taking it. It is a bad idea as deferred interest with a payoff you merely hope to make. Read which kind you are signing; the documents say so plainly.
Can I get HVAC financing with bad credit?
Usually some offer exists: second look lenders such as Foundation Finance and marketplaces serving scores down to the mid 500s operate here. Expect high APRs and possibly a larger dealer fee in the price. Low income households should check utility and state energy programmes and the federal Weatherization Assistance Program first, because some replacements are subsidised or free.
Should I use a home equity loan instead?
For strong credit and a large job, a home equity loan or line often carries the lowest rate in this comparison, because the home secures it. That security is also the risk: the debt is tied to the house. Smaller jobs suit an unsecured loan better, and no financing at all suits a system a repair can keep alive another season.
