GreenSky is one of the largest home improvement POS lenders in the United States, backing installment loans up to $100,000 through a network of bank partners. For HVAC contractors the value proposition is fast, unsecured financing underwritten on the homeowner's creditworthiness, which frequently results in approval amounts larger than the quoted HVAC project.

HVAC dealers integrate GreenSky via the GreenSky Merchant app, online portal, and a direct ServiceTitan Marketplace integration. Customers can apply in under a minute, see real-time decisions, and contractors get up to 70% of project funds upfront with the remainder paid after completion. APRs typically range from roughly 7.99% to 21.19% on standard plans.

GreenSky's merchant fees range from 0% on high-APR standard loans up to ~26% on the richest 0% promo plans. GreenSky was acquired by Goldman Sachs in 2022 and sold to a Sixth Street-led consortium in 2024.
