Consumer financing for HVAC: how to offer it and close bigger jobs

A failed compressor doesn’t care that the homeowner’s savings account is empty. When a full system replacement lands at $9,000-$16,000 and the customer wasn’t planning to spend it this month, “let me get a few more quotes” is usually code for “I can’t write that check today.” Financing is how you turn that stall into a signed job, and how the shop down the road is beating you on jobs you were better qualified to do.

Here’s how it actually works, what it costs you, and how to roll it out without giving away margin.

How contractor financing works

You register as an authorized dealer with a lending partner. The lender holds the license, runs the credit check, handles the disclosures and regulatory compliance, and pays you directly after the work is complete. Your job is small and specific: introduce the option and hand the customer a link or tablet. They apply on their phone, get a decision in minutes, and you get funded on completion. You are not the bank, and you are not on the hook if they stop paying.

That division of labor matters. You get the close and the cash; the lender carries the credit risk and the paperwork.

The dealer fee: the part nobody explains up front

Financing isn’t free to you. The lender charges the contractor a dealer fee on each funded loan. Roughly:

Product	Typical dealer fee
Standard installment loan	~1-6%
12-month 0% “same-as-cash”	~5-9%
18-24 month 0% promo	~9-15%+

The flashier the promo the customer sees, the more it costs you. A 24-month 0% offer can run into the double digits. Providers vary: Wisetack charges a flat ~3.9% on standard loans with promo products stacking on top; GreenSky, Synchrony, and Service Finance publish ranges from roughly 1% to as high as ~15-24% depending on the product. (Confirm current numbers directly with each provider; they change.)

You cannot show the dealer fee to the customer, and you cannot add a surcharge for financing on most programs. So the fee has to live inside your pricing.

How to price the fee in without gouging cash customers

The clean way is to blend it across your book, not bolt it onto financed jobs.

Say 30% of your jobs get financed at a blended dealer fee around 7.5%. That’s 0.30 × 7.5% ≈ 2.25% of cost that needs to be absorbed across every quote. Build that ~2-3% into your standard pricing and the math works: cash customers are barely affected, financed jobs pay for themselves, and you never have to have an awkward “financing costs extra” conversation.

Concretely, on a $12,000 system with a ~2.5% blend baked in, you’re pricing at about $12,300 across the board. The cash customer pays $300 more than a hypothetical fee-free price, noise on a job this size. The financed customer costs you ~$900 in dealer fee on a 12-month promo, but ~$300 of that is already covered by the blend, so the real margin hit is small and predictable. Multiply that by a higher close rate on big-ticket jobs and financing pays for itself several times over.

What you should not do: quote a lower “cash price” and a higher “financed price.” On most dealer agreements that’s a violation, and it trains customers to haggle. Before you finalize how you price the fee in, read your specific lender agreement and check your state/provincial rules: some jurisdictions and some agreements treat any price differentiation, surcharge, or disclosure differently, and U.S. consumer-financing offers are governed by the Truth in Lending Act. When in doubt, ask the lender’s dealer-support line and, for anything gray, your accountant or a lawyer.

The promotional-financing trap (protect your customer, protect your reputation)

The famous “0% for 12-24 months” and “same-as-cash” offers have a catch that burns homeowners who don’t read carefully: most are deferred-interest products. If any balance remains when the promo period ends, interest is charged retroactively: on the original purchase amount, from day one, often at 25-30% APR.

A customer who gets surprised by that will blame you, not the lender. So say it plainly at the table: “This is zero percent if it’s paid off within 12 months. If there’s a balance left after that, they charge back-interest, so treat it like a 12-month plan, not a free ride.” That one sentence protects the relationship and the reviews that follow it.

Which provider(s) to sign up with

You don’t need ten. Start with one strong general partner, and add a second only if you find real approval gaps.

• Broad approval / simple fees: Wisetack is popular for transparent flat pricing and fast, soft-pull approvals (up to ~$25k).
• Deep promo menus / manufacturer ties: GreenSky, Synchrony, and Service Finance offer large menus of promotional products and are often tied to OEM dealer programs (Carrier, Trane, Lennox, etc.). Check whether your distributor or brand already has a preferred program with better rates.
• Bank-backed: EnerBank/Regions and Wells Fargo run large contractor programs.

If you carry a major OEM, ask your distributor first. Brand-sponsored financing often has lower dealer fees than signing up retail.

🇨🇦 In Canada: most of the big US names don’t operate north of the border. Look at Canadian consumer-financing providers instead: Financeit, Snap Financial (goeasy), Flexiti, and Fairstone are the common home-improvement lenders, and several OEM dealer programs run through them. The mechanics (dealer fee, promo/deferred-interest, funded on completion) are the same, but disclosure and cost-of-borrowing rules fall under provincial consumer-protection law rather than the US Truth in Lending Act. Confirm the required disclosures for your province.

Rollout checklist

• Pick one primary lender (two max). Prioritize approval rate and fee transparency over the flashiest promo.
• Check whether your OEM/distributor has a sponsored program with better dealer fees before signing up retail.
• Blend the dealer fee (~2-3%) into your standard pricing: no separate “cash vs. financed” prices.
• Put the apply link on every estimate, your website, and a QR code in the truck.
• Train techs and comfort advisors to offer it every time, not just when a customer flinches at price. “Most folks spread this over monthly payments. Want me to show you what that looks like?”
• Script the deferred-interest warning so every customer hears it.
• Present financing as a monthly number next to the total: “$12,400, or about $172/month.” Monthly payments close bigger systems.
• Track your financing attach rate and approval rate monthly; if approvals are low, add a second lender that catches thinner credit.

The bottom line

Financing isn’t about selling to people who can’t afford your work; it’s about not losing good customers to a cash-flow timing problem, and about letting the homeowner choose the right system instead of the cheapest one their checking account allows. Price the fee in, warn about deferred interest, and offer it on every ticket. Done right, your average job size goes up and your close rate on big-ticket replacements goes with it.
