Worked example
Example: an HVAC company adds three upfitted service vans at $65,000 each. Assumptions for illustration only: 10% down and a 5-year equipment loan at 9% (inside today’s 6.5–12% bank equipment range), computed with the payment formula of our commercial mortgage calculator.
| Amount | |
|---|---|
| Three vans | $195,000 |
| Down payment (10%) | $19,500 |
| Equipment loan, 5 years, 9% | $175,500 — $3,643/mo |
| Per van, per month | about $1,214 |
A van that adds even one or two billable calls a week covers its payment, which is why lenders see service vehicles as low-risk collateral — the van secures the loan, and approval leans on the company’s cash flow and the technician you will put in it. Keep the loan term within the van’s working life; a 5-year loan on a vehicle you will replace in four leaves a balance on a truck you no longer want.
FAQ
Common questions about HVAC and plumbing company financing
Equipment financing covers service vans and HVAC units (1–5 days, 600+ credit). Invoice factoring bridges the payment gap on commercial contracts (24–72 hours). SBA loans work for acquiring a competitor or buying real estate. Lines of credit cover seasonal slow periods. Use the loan type that matches your specific need to minimize cost.
In our example, three upfitted vans at $65,000 each with 10% down are a $175,500, 5-year equipment loan at 9% — about $3,643 a month, or $1,214 per van. The vans are the collateral, so approval leans on the company’s cash flow and credit.
Commercial plumbing contractors often invoice property managers and GCs with 30–60 day terms. Factoring converts those invoices to immediate cash — 85–95% advance at 1.5–5% per 30 days. No debt added. The factor collects from your client. Approval based on client credit, not yours (500+ personal credit OK).
Yes. Commercial vehicle financing covers service vans, trucks, and specialty vehicles at 6.5–20% APR over 2–7 years. Approval in 1–5 days with 600+ credit. The vehicle serves as collateral. Some lenders offer fleet programs with volume discounts. Wrapped vans with company branding are treated identically to unbranded vehicles in underwriting.
A business line of credit ($10K–$500K) set up during your peak season costs nothing until drawn. Use it during slow months for payroll, insurance, and parts inventory. Repay during peak. Apply during a busy period when your revenue looks strongest.
Equipment financing and vehicle loans accept 600+. Invoice factoring accepts 500+ (client credit is the primary factor). Lines of credit need 650+. SBA loans require 680+. HVAC and plumbing businesses with consistent revenue and licensed technicians typically qualify with minimal difficulty for most loan types.
Yes. SBA 7(a) loans up to $5M are well-suited for trade business acquisitions. Lenders value HVAC businesses based on recurring maintenance contracts, licensed technician headcount, and equipment book value. An acquisition with 2+ years of maintenance agreements is considered lower risk. Expect 680+ credit, 10–20% down, and a 30–60 days timeline to close.
