Quick comparison

The best hvac financing companies

#1

Wisetack

Best for: HVAC shops of any size that want financing inside Jobber, Housecall Pro or ServiceTitan with no subscription

★★★★★★★★★★4.6/5 on G2 (26 reviews, checked Nov 2026)

Visit wisetack.com

Starting price3.9% flat dealer fee per financed job (0%–35.9% APR to homeowners; $500–$65,000)

Free planNo — not applicable (lender)

Wisetack is the easiest financing to add: there is no subscription and no enrollment fee, just a flat 3.9% fee on each financed job. Homeowners prequalify with a soft credit check that does not affect their score, then choose from up to eight offers at 0% to 35.9% APR over 3 to 120 months. Loans run from $500 to $65,000, which covers most repairs and full system replacements.

The contractor is paid by bank transfer one to three business days after the job is completed, and the platform plugs into Jobber, Housecall Pro, ServiceTitan and 30-plus other field-service tools. The catch is the 0% promotions: they are optional add-ons that raise the merchant fee, up to 9.9% for a 24-month 0% plan. Choose Wisetack when you want financing inside the software you already use.

What we like

• Flat 3.9% fee per financed job with no subscription, setup fee or monthly minimum
• Native integrations in Jobber, Housecall Pro, ServiceTitan and 30+ field-service tools
• Soft-pull prequalification in about 60 seconds, with up to eight offers per homeowner
• Contractor paid by bank transfer 1 to 3 business days after the job is completed

Watch out for

• Loans top out at $65,000, so whole-home jobs above that need a second lender
• 0% promotions cost extra — up to 9.9% merchant fee for a 24-month 0% plan
• Homeowner APRs run to 35.9% for lower-credit borrowers

#2

Synchrony

Best for: Manufacturer dealers who want the branded HVAC card customers already recognize, with 0% promos

Visit synchrony.com

Starting priceCustom quote (branded HVAC card; 0% APR promos for 12–60 months; terms to 120 months)

Free planNo — not applicable (lender)

Synchrony is the bank behind most branded HVAC cards, including the Carrier Comfort Card and the Trane card. Homeowners get a reusable revolving credit line, with promotional 0% APR plans for 12 to 60 months and fixed-rate terms to 120 months. Approval takes about five minutes with a soft credit pull; the card works only at participating dealers.

The dealer fee is the real cost: standard-rate plans cost the contractor little or nothing, while long 0% promotions run 7% to 12% or more of the ticket. The other trap is deferred interest — if the balance is not paid in full by the end of the promo, interest is charged from the purchase date at the standard APR. Pick Synchrony when you are a manufacturer dealer and want the card your customers already recognize.

What we like

• Branded cards for Carrier, Trane, Lennox and other manufacturers that customers already trust
• Promotional 0% APR plans for 12 to 60 months, with fixed-rate terms to 120 months
• Revolving credit line the homeowner can reuse for later repairs
• Approval in about five minutes with a soft credit pull

Watch out for

• Most 0% offers are deferred interest — unpaid balances are charged interest from the purchase date
• Long 0% promotions cost the dealer 7% to 12% or more of the ticket
• Standard APR runs about 26.99% to 29.99% once a promotion ends

#3

GreenSky

Best for: Multi-truck HVAC shops doing $5 million or more a year that need 0% firepower on $15,000 replacements

Visit greensky.com

Starting priceCustom quote (reduced-rate plans 5.99%–11.99% APR; loans to $100,000; terms to 144 months)

Free planNo — not applicable (lender)

GreenSky is the oldest large home-improvement lender in this list, with more than $30 billion in originations, and it is built for big tickets: loans run to $100,000 with terms to 12 years. Reduced-rate plans run roughly 5.99% to 11.99% APR, and deferred-interest promotions offer no interest if the balance is paid in full within the promotional window. Homeowners apply in about 90 seconds through the contractor.

The dealer fee is the trade-off. Standard 9.99% APR plans cost the contractor nothing, but 0% promotional plans run 4.99% to 12.99% of the job, and underwriting has tightened since the Goldman Sachs era — approval rates fell for borrowers in the 660 to 700 FICO range. GreenSky suits multi-truck HVAC shops doing $5 million or more a year that need 0% firepower to close $15,000 replacements.

What we like

• Loans to $100,000 with terms to 12 years, the largest limits beside Service Finance
• Reduced-rate plans from 5.99% to 11.99% APR for qualified borrowers
• Application takes about 90 seconds through the contractor
• The largest home-improvement financing platform in the US, with over $30 billion originated

Watch out for

• Deferred-interest promos charge interest from day one if the balance is not paid in full
• 0% promotional plans cost the dealer 4.99% to 12.99% of the job
• Underwriting tightened after the Goldman Sachs era, with lower approvals at 660 to 700 FICO

#4

Service Finance

Best for: Lennox, Carrier, Trane and Bryant dealers who want manufacturer-subsidized promos and $100,000 limits

Visit servicefinance.com

Starting priceCustom quote (0% APR promos; standard plans at 9.99% APR; loans to $100,000)

Free planNo — not applicable (lender)

Service Finance Company, owned by Truist Bank, is the lender most deeply embedded in HVAC manufacturer dealer programs: Lennox Premier Dealers, Carrier President's Award dealers, Trane Comfort Specialists and Bryant Factory Authorized Dealers usually have it pre-loaded. Loans run to $100,000 per project, the highest limit in this list, with 0% APR promotions and standard plans at 9.99% APR.

Standard-rate plans typically cost the dealer nothing, while 0% promotions for 12 to 24 months run 6.5% to 9.9% in dealer fees, and 60-month 0% promotions run 4% to 7%. Funding takes 24 to 72 hours after completion, slower than Wisetack, and customer service draws the most complaints in this category. Choose Service Finance when you sell through a manufacturer dealer program and want its subsidized seasonal promotions.

What we like

• Pre-loaded in Lennox, Carrier, Trane and Bryant manufacturer dealer programs
• Loans to $100,000 per project, the highest limit in this list
• Standard 9.99% APR plans typically cost the dealer nothing
• Manufacturer-subsidized seasonal promotions on 0% plans

Watch out for

• 0% promotions for 12 to 24 months run 6.5% to 9.9% in dealer fees
• Funding takes 24 to 72 hours after completion, slower than Wisetack
• Customer service draws the most complaints in this category, per 2026 contractor comparisons

#5

Hearth

Best for: Contractors financing big tickets above $65,000 and homeowners with FICO scores from 550

★★★★★★★★★★4.7/5 on Trustpilot (1,734 reviews, checked Nov 2026)

Visit gethearth.com

Starting priceFrom $1,499/year (flat subscription; no per-loan dealer fee; loans $1,000–$250,000)

Free planNo — not applicable (lender)

Hearth is a marketplace, not a lender: one prequalification form reaches 18 lending partners, with loans from $1,000 to $250,000, terms from 2 to 12 years, and rates from 4.99% APR for borrowers with FICO scores as low as 550. There is no per-loan dealer fee — the contractor pays a flat annual subscription instead — and 0% introductory APR card options are available for qualifying homeowners.

The subscription is the decision. Hearth's own 2026 comparison puts most companies at $1,499 to $4,999 a year, which pays off once you finance regularly but stings if you only finance a few jobs a year. Hearth also bundles estimates, e-signed contracts, invoicing and an AI receptionist, so it is really a sales platform with financing inside. Pick Hearth for big tickets above Wisetack's $65,000 ceiling and for lower-credit homeowners.

What we like

• One form reaches 18 lenders, with loans from $1,000 to $250,000
• No per-loan dealer fee — a flat annual subscription keeps 100% of each job's revenue
• Serves FICO scores from 550, with rates from 4.99% APR
• Bundles estimates, e-signed contracts, invoicing and an AI receptionist

Watch out for

• Subscription runs $1,499 to $4,999 a year, which stings if you finance only a few jobs
• Hearth is a broker, not a lender — the rate and terms come from third-party lenders
• Auto-renewal and cancellation complaints show up in reviews; calendar the renewal date

#6

GoodLeap

Best for: Homeowners planning heat pump conversions and electrification jobs that need a low fixed payment over 10 to 15 years

Visit goodleap.com

Starting priceCustom quote (home-improvement loans to $55,000; terms 5–15 years; 0% APR for 18 months on qualifying projects)

Free planNo — not applicable (lender)

GoodLeap started in solar and has pushed hard into HVAC over the last two years, and its strength is long, low-APR installment loans rather than short 0% promotions. Home-improvement loans run to $55,000 with fixed rates, no upfront costs and terms of 5 to 15 years, and there is no prepayment penalty. An 18-month no-interest, no-payments promotion is available on qualifying projects.

The dealer fee on long-term low-APR products runs 6% to 12% of the ticket, which is the price of the low rate — the contractor subsidizes it. GoodLeap returns up to three loan options with estimated monthly payments, and AutoPay earns a 0.50% rate discount. Choose GoodLeap for whole-home heat pump conversions and electrification jobs where a low fixed payment over 10 to 15 years beats a short promo.

What we like

• Fixed low-APR installment loans with terms to 15 years, not just short promos
• Loans to $55,000 with no upfront costs and no prepayment penalty
• 18-month no-interest, no-payments promotion on qualifying projects
• AutoPay earns a 0.50% rate discount

Watch out for

• Long-term low-APR products cost the dealer 6% to 12% of the ticket
• Wrong tool for a short 0% close on a $9,000 furnace swap
• No single published APR — the rate is set at the credit review for each borrower

#7

Wells Fargo Home Projects

Best for: Any-brand HVAC dealers who want a bank-backed card with a 0% 12-month plan or a 9.99% 96-month plan

Visit wellsfargo.com

Starting priceCustom quote (0% APR for 12 months or 9.99% APR over 96 months; standard APR 28.99%)

Free planNo — not applicable (lender)

Wells Fargo Home Projects is the credit card behind many HVAC dealers' financing, and it works with any brand of equipment. Two plans cover most jobs: 0% APR for 12 months if the balance is paid in full, or 9.99% APR with 96 equal monthly payments. The minimum purchase is $1,000, and the card carries no annual fee.

The number to respect is the standard APR: 28.99% for new accounts, charged from the purchase date if a 0% balance is not paid in full within the promotional period. That makes the 12-month plan a same-as-cash deal only for homeowners who can actually clear the balance in a year. Pick Wells Fargo when you want a bank-backed card that any brand dealer can offer, and steer disciplined buyers to the 9.99% plan when the balance will last longer.

What we like

• Works with any HVAC brand, not just one manufacturer's dealers
• 0% APR for 12 months if paid in full, or 9.99% APR over 96 equal payments
• No annual fee on the Home Projects card
• Bank-backed program with a long track record in home improvement

Watch out for

• Standard APR is 28.99% for new accounts if a 0% balance is not paid in full
• The 0% plan is deferred interest in practice — interest is charged from the purchase date
• Minimum purchase of $1,000 rules out small repairs

#8

EnerBank USA

Best for: Dealers who already offer EnerBank and want a specialist home-improvement lender with 0% same-as-cash loans

Visit enerbank.com

Starting priceCustom quote (dealer-set plans; 0% same-as-cash 12-month loans; reduced-rate loans from 6.99% APR)

Free planNo — not applicable (lender)

EnerBank USA, a Regions Bank brand and FDIC-insured lender, has specialized in home-improvement loans since 2001. Loans run from $1,000 to $100,000, with 0% same-as-cash loans for 12 months and reduced-rate installment loans from 6.99% APR. Terms run to 12 years on some plans, and dealer materials report about four in five applicants are approved.

EnerBank publishes no single public rate card — the plans and dealer fees are set per dealer, so the option sheet your dealer hands you is the only firm quote. Dealer fees run about 6% on 12 to 18-month 0% loans, and the 12-month same-as-cash loan accrues interest at about 17.99% if it is not repaid within the year. Choose EnerBank when your dealer already offers it and you want a specialist lender with a long HVAC track record.

What we like

• Specialist home-improvement lender since 2001, FDIC-insured through Regions Bank
• 0% same-as-cash loans for 12 months alongside reduced-rate loans from 6.99% APR
• Loans from $1,000 to $100,000 with terms to 12 years
• Dealer materials report about four in five applicants are approved

Watch out for

• No single public rate card — plans and dealer fees are set per dealer
• The 12-month same-as-cash loan accrues interest at about 17.99% if not repaid in time
• Dealer fees run about 6% on 12 to 18-month 0% loans

#9

Acorn Finance

Best for: Contractors who want to offer financing with no dealer fee and no subscription, through a 30-lender marketplace

Visit acornfinance.com

Starting priceNo contractor fee (marketplace; homeowner APRs 6.99%–35.99%; loans $1,000–$100,000)

Free planYes — free to compare offers (no contractor fee)

Acorn Finance is a free marketplace that compares loan offers from 30 or more competing lenders in about 60 seconds, with no hard credit check to see the offers. Home-improvement loans run from $1,000 to $100,000 with APRs from 6.99% to 35.99% and terms from 12 to 144 months, for borrowers with credit scores from 550. Contractors pay no dealer fees at all.

Because Acorn is a marketplace, the rate and lender change with the borrower's credit — the headline 6.99% APR needs excellent credit, and the featured Upgrade loans carry a 1.85% to 9.99% origination fee deducted from the proceeds. Acorn added 0% APR promotional financing in April 2025, and most loans fund within 48 hours of approval. Pick Acorn when you want to offer financing without paying a dealer fee or a subscription.

What we like

• Free to compare: 30+ lenders in about 60 seconds with no hard credit check
• No dealer fee and no subscription for contractors
• Loans from $1,000 to $100,000 with terms to 144 months, FICO from 550
• 0% APR promotional financing added in April 2025

Watch out for

• Headline 6.99% APR needs excellent credit; most borrowers see higher rates
• Featured Upgrade loans carry a 1.85% to 9.99% origination fee taken from the proceeds
• Acorn is a marketplace, not a lender — the loan terms come from third-party lenders

#10

SoFi

Best for: Homeowners with good to excellent credit who would rather borrow directly than use a contractor's financing

Visit sofi.com

Starting priceNo required origination fee (personal loans $5,000–$100,000; 6.99%–35.49% APR with discounts)

Free planNo — not applicable (lender)

SoFi is the direct personal-loan option in this list: homeowners borrow $5,000 to $100,000 themselves, with fixed APRs from 6.99% to 35.49% with all discounts and terms from two to seven years. There is no required origination fee, no prepayment penalty and no late fee, and funding can land the same day the loan is approved. The rate check uses a soft credit pull.

The catch is the floor: the $5,000 minimum rules out small repairs, and the lowest rates need good to excellent credit — SoFi's average approved borrower carries about a 746 FICO — plus autopay and a member discount that requires direct deposit or qualifying deposits. SoFi works best as the borrow-it-yourself backup when the contractor's own financing declines the homeowner or the job is too small for a dealer program.

What we like

• No required origination fee, no prepayment penalty and no late fee
• Loans from $5,000 to $100,000 with same-day funding on approval
• Fixed APRs from 6.99% to 35.49% with all discounts, terms of two to seven years
• Rate check uses a soft credit pull that does not affect the borrower's score

Watch out for

• $5,000 minimum rules out small repairs and single-component replacements
• Lowest rates need good to excellent credit plus autopay and a member discount
• Not a contractor program — the homeowner applies alone, with no dealer support

The 10 best hvac financing companies below fall into two groups: contractor programs that put financing on the quote, and direct loans the homeowner arranges alone. We ranked them by fit for the most common buyer — an HVAC contractor who wants more replacements closed, and the homeowner paying for one — starting with the cheapest dealer cost and ending with the borrow-it-yourself options, and every APR, loan limit and dealer fee was checked on November 8, 2026.

How to choose the best hvac financing companies

• Count the dealer fee first. The fee is the contractor's real cost: 3.9% per job on Wisetack, 5% to 13% on most 0% promotions, or a flat $1,499 to $4,999 a year on Hearth. A program that looks free to the homeowner is never free to the shop.
• Ask whether the 0% plan is deferred interest. Most 0% HVAC offers accrue interest from the purchase date and charge it all if the balance is not paid in full. True 0% APR plans exist, but they are the exception, not the rule.
• Match the loan limit to the ticket. Wisetack stops at $65,000, GreenSky and Service Finance reach $100,000, and Hearth reaches $250,000. A program whose ceiling sits below your average replacement cannot close your average replacement.
• Check the credit floor. Hearth and Acorn Finance serve FICO scores from 550, while Synchrony's 0% promotions and SoFi's lowest rates need good to excellent credit. The floor decides how many of your customers actually qualify.
• Check funding speed. Wisetack pays in one to three business days after completion, Hearth in 24 to 48 hours, and Service Finance in 24 to 72 hours. Slow funding is a cash-flow cost, not just an inconvenience.
• Decide who applies. Contractor programs put the application on the quote at the kitchen table; personal loans like SoFi leave the homeowner to apply alone. The first closes more jobs.

Financing closes more jobs, but only if homeowners find the business first — our local SEO service covers the visibility side. And once a financed job is done, ask for the review while the customer is still happy: the free Google review link generator builds a one-tap review link for the business.

Whatever you shortlist, run one real job through it before you commit the whole season to it. Offer the financing on a live quote, watch how the homeowner reacts to the monthly payment, and check that the funding lands when the lender says it will. The programs in this list all prequalify with a soft credit check, so the trial costs the homeowner nothing and tells you more than any brochure can.

HVAC financing companies pricing: what you will actually pay

Take a $12,000 full system replacement. On Wisetack's standard plan the contractor pays 3.9% of the job, or $468, and the homeowner's payment follows the APR: Wisetack's own published example is $253.54 a month for a $5,500 loan at 9.9% APR over 24 months, which scales to about $553 a month on $12,000 at the same rate and term. On a 0% promotion for 18 months the homeowner pays $667 a month and nothing in interest — but the dealer fee at 9% is $1,080, more than double the standard-plan fee.

Now run the same $12,000 job through the subscription model. Hearth charges $1,499 a year with no per-loan fee, so a shop that finances 20 jobs a year at $12,000 each pays $1,499 on Hearth against $9,360 on Wisetack's standard plan — a $7,861 gap that only exists because the volume is high. At three financed jobs a year the math flips: $1,404 on Wisetack against $1,499 on Hearth, and the subscription loses. Hearth breaks even against Wisetack's 3.9% fee at about $38,400 of financed volume a year.

Two more numbers to carry into the decision. First, the long-term option: GoodLeap's published example puts a $10,000 loan at 7% APR at about $116 a month over 10 years, which is how a heat pump conversion becomes a utility-bill-sized payment — but the dealer pays 6% to 12% of the ticket for that low rate. Second, the penalty for missing a promo deadline: a $12,000 balance left unpaid after a 12-month 0% plan starts accruing interest at the standard APR, about 26.99% to 29.99% on Synchrony and Wells Fargo, charged from the purchase date. If you run a contracting business rather than a one-off project, the payment side matters too — see our guide to the best contractor payment software.

Know the difference: deferred interest vs true 0% APR

The confusion in this category is between two products that are both sold as "0% financing." With true 0% APR, no interest accrues during the promotional period: the homeowner owes exactly what was borrowed, and paying it off on time costs nothing extra. With deferred interest, interest accrues at the full standard APR — typically 26.99% to 29.99% on Synchrony and Wells Fargo plans — from the purchase date, and it is only waived if the full balance is paid before the promotion ends. If even one dollar remains, the entire accrued interest becomes due at once.

The second confusion is who pays for the promotion. A 0% offer is never free money: the lender recovers the interest from the contractor through the dealer fee, which runs 5% to 13% of the job on most 0% plans. That fee is why a shop that pushes 0% on every quote can close more jobs and still earn less per job. Wisetack is the most transparent about this — its 24-month 0% plan costs up to 9.9% against 3.9% for a standard-rate plan — while GreenSky, Synchrony and Service Finance set the fee per plan and per dealer.

A third distinction worth knowing is dealer financing versus a personal loan. Dealer financing is arranged at the quote, through the contractor's program, and the lender pays the contractor directly. A personal loan from SoFi or a marketplace is borrowed by the homeowner alone and paid to the contractor as cash. The personal loan is the fallback when the dealer program declines the homeowner, when the job is too small for a dealer minimum, or when the homeowner simply prefers to keep the contractor out of their credit.

Quick comparison: tool type by need

Mistakes to avoid

• Selling a 0% plan without checking deferred interest. If the plan accrues interest from day one, a customer who misses the deadline by a month owes 12 months of interest at 26% to 29%. Confirm in writing whether the plan is deferred interest or true 0%.
• Budgeting on the headline APR. The lowest APRs need excellent credit: 6.99% at SoFi and Acorn, 4.99% at Hearth. Most borrowers see a higher rate, so compare offers on the APR the customer actually qualifies for.
• Picking a lender whose limit is below your average ticket. Wisetack's $65,000 ceiling covers most replacements, but a whole-home job with ductwork and electrical work can pass it. Check the ceiling before you print it on the quote.
• Ignoring the dealer fee in the job price. A 9% fee on a $12,000 job is $1,080 out of the margin. Price financed jobs with the fee in the number, or the close-rate lift from financing can still lose money.
• Offering financing with no second-look path. A prime lender declines a large share of applicants. Keep a marketplace like Hearth or Acorn behind the first offer so a decline becomes a second offer, not a lost job.

How we chose

We checked each lender's own published terms on November 8, 2026 and recorded the APR range, loan limits and dealer cost exactly as published, and we ranked the companies by fit for the most common buyer — an HVAC contractor who wants more replacements closed — not by brand size. Where a lender publishes no public rate card, we used the terms shown on dealer and manufacturer program pages and on independent 2026 comparisons that quote the vendor's own materials: that applies to Synchrony, GreenSky, Service Finance, Wells Fargo and EnerBank, whose plans and dealer fees are set per dealer. This list carries only two review ratings — Wisetack at 4.6 out of 5 on G2 (26 reviews) and Hearth at 4.7 out of 5 on Trustpilot (1,734 reviews) — because the other lenders' review pages are fragmented across several profiles or could not be verified, and we would rather show no rating than a stale or estimated one. LightStream was left out because it stopped accepting new loan applications on October 17, 2026, and Upgrade was left out for space: it overlaps Acorn Finance and SoFi as a fair-credit personal loan. No vendor paid for a place in this list, and none of the links here are affiliate links.

What to do next

Start with the program that matches your average ticket: Wisetack if most jobs sit under $65,000, Hearth if they run above it, and a marketplace behind either one for the customers the first lender declines. Put the financing offer on the quote itself, not on a flyer in the truck, and train the tech to state the monthly payment before the total. If the jobs are coming in but the phones are not ringing, compare providers in our guide to marketing software for contractors. Once your tools are in place, find out what's holding your rankings back.
