Can I get a HVAC business loan with bad credit in Wisconsin?

Short answer

Yes—if your Wisconsin HVAC business has a FICO of 500‑579, you can qualify for a working‑capital or equipment loan with 9‑12% APR and 12‑36 month terms. Check rates.

The specifics

A 9‑12% APR range is standard for equipment financing in Wisconsin when a contractor meets the SBA’s 7‑a criteria. The SBA allows terms of 12‑36 months for most equipment purchases; larger fleets may extend to 84 months [SBA.gov]. Typical loan balances for HVAC contractors range from $10 k to $200 k, with a required down‑payment of 15‑20% of the principal. Approval usually requires at least 24 months in business, a minimum gross monthly revenue of $30 k, and a debt‑to‑income ratio under 40% of the business’s monthly income [SBA.gov]. You can get a soft pull to keep your credit score intact—no hard inquiry is needed [SBA.gov].

Qualification & edge cases

If you’re operating for less than 12 months, lenders may require a personal guarantee or a higher down‑payment. A high debt‑service coverage ratio (DSCR) of 1.25× or higher is also a prerequisite for most SBA‑backed loans. If your credit score is below 500, options narrow to lender‑specific disaster‑resilience programs or federal grant‑based work‑capital lines, but interest rates can climb to 18‑20% [SBA.gov]. Veterans can tap into dedicated “WRHP” programs that often feature lower APRs and longer repayment terms—see the veteran‑friendly financing options in Wisconsin here Bad Credit Financial Services and Lending for Veterans in Wisconsin.

Background & how it works

The HVAC market in the U.S. is projected to grow 4.5 % CAGR through 2030, driven by modern building demands and renewable retrofits, according to a 2026 report from [MarketsandMarkets]. Seasonal spikes mean many contractors need working capital for the off‑season lull and equipment upgrades. Lenders structure loans so that monthly payments do not exceed 12 % of the contractor’s gross revenue—a figure aligned with SBA DSCR rules. With the right collateral (e.g., new HVAC units or service vehicles) and a solid cash‑reserve plan (usually 3‑6 months’ worth of operating expenses), the loan process can take 30‑45 days from application to funding, with funds arriving in 3‑5 business days [Trane].

Bottom line

A 500–579 FICO score can still unlock HVAC business loans in Wisconsin—look for equipment or working‑capital programs offering 9‑12% APR and 12‑36 month terms. Check rates today.
