Can I get a business loan for my HVAC company in Michigan with bad credit?

Yes — you can get a Michigan HVAC business loan with a bad credit score. SBA 7(a) works for scores as low as 620, and alternative lenders serve scores 580‑619. See your rate in a few seconds — no hard credit pull.

The specifics

SBA 7(a) is the most frequently used route for HVAC contractors with credit scores in the fair‑credit range. According to ServiceTitan, the SBA 7(a) program typically accepts borrowers with a minimum FICO of 620 for small‑to‑mid‑sized businesses that have been operating for at least two years and can demonstrate stable cash flow.

If your score falls between 580 and 619, many Michigan‑based alternative lenders can still provide working‑capital or equipment financing. QuickBridge, for example, offers lines of credit and equipment loans to borrowers with those credit scores, usually in the 9‑12 % APR range and with approval times of 30 – 45 days.

Typical loan amounts for HVAC businesses in 2026 range from $20 k to $2 M, depending on the lender and collateral. Either route requires 40 % of gross monthly revenue or less as a debt‑to‑income ratio, a debt‑service coverage ratio of 1.25×, and at least three to six months of cash reserves to qualify. If you need to purchase equipment, a 15 %‑20 % down payment is often advised.

Qualification & edge cases

If you’ve been in business fewer than two years, the SBA’s standard criteria may deem you high‑risk; in that case, look at SBA micro‑loan programs or equipment‑specific lenders that accept shorter track records.

A recent bankruptcy or charge‑off can delay approval, but many alternative lenders will evaluate the situation on a case‑by‑case basis, especially if your current cash flow remains strong.

Lenders may also scrutinize the use of funds. Loans tied to a specific purchase—such as a new heat‑pump system—often close faster than general operating loans.

A co‑signer or guarantor with a higher score can lower the APR by 1‑3 % and improve your odds. However, it also brings personal liability.

Background & how it works

The HVAC market in Michigan is growing at an estimated 4‑6 % annually, driven by new construction and commercial retrofits (MarketsandMarkets). This growth creates seasonal cash‑flow gaps that many contractors need to bridge. Traditional banks tend to require excellent credit, but the SBA 7(a) program offers a more accessible path for HVAC businesses with fair credit scores.

In 2026, lenders have adapted by offering shorter‑term equipment financing and fast‑track working‑capital lines, which can be secured by the equipment itself. The SBA’s 7(a) limits rates to 8‑10 % APR for good credit and 10‑13 % APR for fair credit, while alternative lenders often provide 9‑12 % APR for equipment leases.

Lenders also consider an applicant’s cash‑flow, so providing a 12‑month waterfall or revenue/profit statement can streamline the process. If you’re a veteran contractor, the Michigan‑specific line of credit for veterans may offer even more favorable terms.

Bottom line

A high‑score HVAC business owner in Michigan can secure a loan through SBA 7(a) or an alternative lender, even with a bad credit history. Each option has clear eligibility criteria and competitive rates—use the affordability calculator now to see your qualifying amount and monthly payment.
