HVAC Financing for Customers: The 2026 Dealer Fee, Promo, and Close-Rate Guide

HVAC shops that always offer financing close 50% of replacement quotes versus 38% for shops that mention it only when the customer asks, per the 2026 ACHR News close-rate survey. That 12-point gap on a $14K average ticket is the difference between $5,300 and $7,000 RPE on the same install hour.

A homeowner staring at a $13,500 cash quote for a 16-SEER2 heat pump is comparing it to savings they do not have. The same homeowner staring at a $189 monthly payment is comparing it to their current electric bill. Same job. Same price. Completely different close.

This is the 2026 buyer’s view on HVAC financing: the 5 lenders shops actually run, what each costs in dealer fees, the Section 25C math homeowners now expect, and the in-home script that moves close rate without raising the ticket.

Why HVAC financing matters more than other trades

Most HVAC system replacements land between $8,500 and $16,750. New-construction ducted systems with electrical upgrades push $20K-$28K. Geothermal and whole-home heat pump retrofits clear $30K.

At those numbers, homeowners shop. The average replacement gets 3.4 bids. A $13,500 bid presented as a cash number loses to a $14,500 bid presented as a $192 monthly payment, even when the $13,500 shop is the better installer.

The decision-stage objection in HVAC is almost never “I do not want the system.” It is “I cannot drop $14K right now.” Financing dissolves that. Per ServiceTitan’s HVAC financing benchmark, shops that lead with a monthly payment finance 42% of new system sales versus 21% for shops leading with the total price. The framing alone doubles the financed share.

The average financed HVAC customer is not a credit risk. Wisetack’s 2026 financing benchmark shows the approved median customer carries a 730 FICO and $98K household income. Dual-income households protecting their emergency fund, not subprime borrowers chasing a payment plan.

The 5 HVAC-friendly financing lenders in 2026

There are dozens of lenders pitching HVAC programs. Five own the category.

Service Finance Company (SFC)

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 SFC pre-loaded with subsidized promo rate sheets.

2026 dealer fees: 6.5-9.9% on 0% APR 12-24 month promos. 4-7% on 60-month 0% promos. 1-3% on reduced-rate plans. 0% on standard 9.99% APR. Loan limits up to $100,000 per project, the highest in the category.

Best for: Full system replacements, dual-system installs, ducted heat pump retrofits with electrical upgrades.

Watch out for: SFC customer service is the most-complained-about in the category. Lending mechanics work but expect 24-72 hour funding.

Synchrony Home

Synchrony Home (contractor arm of Synchrony Bank, parent of CareCredit) is the second-largest HVAC lender by volume. Strong on Carrier, Bryant, and Trane dealer programs with negotiated rate sheets.

2026 dealer fees: 0.99-15% depending on product, per Synchrony’s contractor financing breakdown. 0% on standard 9.99% APR. 3.99-11.99% on 0% deferred interest promos (12-60 months).

Best for: Carrier-family dealer programs, full-home comfort packages bundling HVAC with water heater and air-quality upgrades.

Watch out for: Deferred interest is the trap most likely to generate a complaint a year after install. Miss the promo-end date and Synchrony retroactively bills all accrued interest at 28.99% APR.

GoodLeap (formerly Loanpal)

Built on solar, pushed hard into HVAC and ducted heat pumps over the last 24 months. Strength is long-term low-APR installment loans (5.99-9.99% APR over 10-25 years) rather than 0% promos.

2026 dealer fees: 6-12% on long-term low-APR products. 3-7% on shorter heat pump loans (60-120 month terms).

Best for: Whole-home heat pump conversions and electrification retrofits bundling solar, battery, and HVAC. Long payments ($95-$140/month over 15 years) often land below the existing utility bill.

Watch out for: Wrong lender for short-promo 0% closes. Forcing GoodLeap on a $9K furnace swap wastes tech time.

Wisetack

Easiest entry point for shops under $2M revenue and the strongest fallback for mid-FICO customers. No enrollment fee, no monthly minimums, no chargebacks. Soft credit pull approval in 60 seconds via text link.

2026 dealer fees: 3.9-10% across the product menu, per BuildFolio’s Wisetack breakdown. 80% approval rate. Loan limits up to $25,000.

Best for: Service-plus-install jobs $1K-$15K, partial replacements, water heaters, mini-splits, repairs over $2K rolled into a payment plan.

Watch out for: $25K cap means Wisetack cannot handle full ducted replacements with electrical upgrades on its own. Use as a complement to SFC or Synchrony.

GreenSky (Sixth Street ownership)

GreenSky was acquired by Goldman in 2022 and sold to a Sixth Street consortium in 2024. Still over $30B in originations.

2026 dealer fees: 0% on standard 9.99% APR. 4.99-12.99% on 0% promotional plans (6-24 month deferred interest). 6.99-9.99% on reduced-rate plans.

Best for: Multi-truck HVAC shops doing $5M+ revenue with consistent $15K+ replacement volume.

Watch out for: Approval rates dropped 8-12 points in the 660-700 FICO range during the Goldman era. Cross-check declined GreenSky applications against Wisetack.

The 0% promo math on a $13,500 heat pump

Every 0% APR HVAC promo is subsidized by someone. There is no free money from the lender.

A $13,500 16-SEER2 heat pump on a 0% APR 18-month Service Finance promo with a 9% dealer fee:

• Customer pays: $13,500 in 18 monthly installments of $750. No interest.
• Lender funds the contractor: $13,500 - (9% x $13,500) = $12,285
• Lender keeps: $1,215 as compensation for forgoing the interest the homeowner would normally pay.

The contractor is the one underwriting the 0% promo through the dealer fee. The shop trades $1,215 for a close that would not have happened at cash.

The math works when the close-rate lift covers the fee. If the job had a 35% gross margin at cash ($4,725), eating $1,215 still leaves $3,510 in gross profit. The math breaks on small tickets with thin margins. A $4,500 furnace swap at 22% gross margin nets $990. Put it on a 0% 12-month promo at 7% dealer fee ($315) and the net drops to $675. At that point 0% APR is destroying the job.

Most successful 2026 HVAC shops run a two-track menu:

• 0% APR promos on replacements over $8,000 (full systems, dual-fuel, heat pumps with electrical) where the close-rate lift justifies the 6.5-12% fee.
• Standard 9.99% APR or 5.99% reduced-rate plans with 0-3% fees on repairs and partial replacements under $8K.

Bake the dealer fee into the price book so cash and financed quotes match. A homeowner who sees “$13,500 cash / $14,500 financed” picks cash or walks. A homeowner who sees “$13,500, or $750/month for 18 months” picks one and signs.

Section 25C and the IRA rebate math homeowners now expect

The federal tax credit landscape changed how HVAC quotes get presented in 2026. Every system replacement quote now needs a Section 25C line.

The Section 25C Energy Efficient Home Improvement Credit gives homeowners 30% of project cost up to $2,000 on qualifying heat pumps (CEE highest-tier rated) installed and operational by December 31, 2026.

The $2,000 heat pump credit is separate from the $1,200 general cap on insulation, windows, doors, and panel upgrades. A heat pump install bundled with insulation and panel work can stack to $3,200 in a single tax year.

A worked example on a $13,500 heat pump:

• Cash price: $13,500
• Section 25C credit: $2,000
• Effective customer cost after credit: $11,500
• Monthly payment on 0% APR 18-month financing: $750 for 18 months

Two operational notes that catch shops off-guard:

The 17-character product PIN. Starting January 1, 2026, the IRS requires homeowners to enter the manufacturer’s qualified product PIN on Form 5695 to claim the credit, per the IRS Section 25C guidance. PIN must appear on the AHRI certificate or invoice. Shops that skip it get angry March phone calls from CPAs.

The credit is non-refundable. The homeowner must owe at least $2,000 in federal income tax that year to capture the full $2,000. Households in the $50K-$80K AGI band sometimes only capture $800-$1,400. Set the expectation as “up to $2,000” in the quote, not “$2,000.”

The credit does not require the homeowner to pay cash. A financed $13,500 heat pump still claims the full $2,000 credit. The credit applies to total qualifying project cost, not to the payment method.

Stack 25C with state and utility rebates. Massachusetts, New York, Vermont, Maine, California, Oregon, and Washington run heat pump rebate programs between $750 and $10,000 per system. Local utility rebates (Eversource, National Grid, ConEd, PG&E) layer on $500-$2,500 more. A $13,500 heat pump in Massachusetts can drop to $5,500 effective customer cost after stacking federal, state, and utility incentives.

The in-home presentation script that moves close rate

The lender and promo math only matter if the monthly payment is on the iPad at the moment of decision. Three rules from shops hitting 50%+ close rate on replacements.

1. Lead with the monthly payment, not the total or the APR. Homeowners do not run amortization in their heads. They know what their electric bill is.

Script that works: “The 16-SEER2 system runs $13,500 installed, but most of our customers go on the 0% APR plan, which puts it at $750 per month for 18 months. About what you pay between your power bill and streaming subscriptions.”

2. Present the monthly payment on every tier. Run good-better-best, put a cash price AND a monthly payment line on each tier. The middle tier becomes the obvious pick when financing makes the premium tier reachable instead of impossible.

A multi-truck HVAC owner on the Owned and Operated podcast described shifting from cash-only to monthly-payment-led presentations. Average ticket held at $14,400. Close rate moved from 38% to 51%. Revenue per estimate jumped from $5,472 to $7,344, a 34% lift with no marketing changes.

3. Pre-fill the application on the iPad before the homeowner asks. Tech opens the financing app, enters price and term, shows the screen with soft-pull approval already complete. Customer says “tell me more” or “I’ll pay cash” within 30 seconds. Either answer is faster than waiting.

A small HVAC owner on r/HVAC posted his close-rate math after switching from a paper financing flyer to in-quote presentation on ServiceTitan with Service Finance. Old close rate at $13,800 average ticket: 33%. New close rate at $14,200 average ticket: 49%. Same techs. The only change was the financing application running on the iPad inside the proposal.

The common HVAC financing mistakes

Patterns from contractors who tried financing and gave up before it moved the numbers:

• Mentioning financing only after the customer says the price is too high. By then the customer is mentally at the next bid. Silence reads as “this shop does not offer it” and 70-80% of homeowners will not ask.
• Running a single lender as the entire program. Different lenders approve different credit tiers. A Service-Finance-only shop misses the 660-700 FICO customers Wisetack would have approved. A Wisetack-only shop cannot fund the $30K dual-system replacement. The 2026 standard is a primary lender plus a backup.
• Offering 0% APR on every job regardless of ticket size. 6.5-12% dealer fees destroy margin on small tickets. Reserve 0% for replacements where it moves close rate. Use standard or reduced-rate APR with 0-3% fees on everything else.
• Hiding the dealer fee with a financing surcharge. Charging a “3% financing fee” is illegal in most states (California, Oregon, Washington, New York have explicit prohibitions). Bake the fee into the price book so cash and financed prices match.
• Letting techs explain deferred interest verbally. “If you pay it off in 18 months it’s 0%” is operationally a disaster. Miss the deadline by a day and Synchrony retroactively bills 18 months of 28.99% interest. Use written disclosure and have the customer e-sign during application.
• Skipping the AHRI certificate and product PIN on the invoice. Starting in 2026, homeowners need the manufacturer PIN to claim Section 25C. Shops that forget create their own CSR problem next March.

The honest take

HVAC financing is the single highest-leverage change most replacement-focused shops can make to close rate and average ticket in 2026. The math is uncomfortable (6.5-12% on promo deals) but the close-rate lift holds across the ACHR survey data, ServiceTitan benchmarks, and the shop numbers posted on r/HVAC and r/sweatystartup.

Shops that get it right treat financing as the default offer on every replacement quote, run a two-track menu (0% promos on jobs over $8K, standard or reduced-rate APR elsewhere), pick lenders by credit-tier coverage rather than brand loyalty, and put the Section 25C credit on every quote without the homeowner asking.

Shops that get it wrong run a single lender as a courtesy, mention financing only when the customer pushes back on price, and wonder why their close rate is stuck at 32% while a competitor on the same street closes 50% on the same Carrier and Trane equipment.

The lever is real. The Section 25C math is real. The execution is the gap. The /for/hvac/ page maps the rest of the operator stack.
