HVAC company financing fits three product types: equipment financing for service trucks, refrigerant recovery machines, diagnostic tools, and brazing equipment (6-25% APR, equipment as collateral, Section 179 deduction eligible); a business line of credit to smooth Q4-Q1 slow-season payroll + summer parts inventory build; and SBA 7(a) for shop expansion, second-location buildout, or commercial property acquisition. HVAC (NAICS 2382) is an SBA-favored industry — typically strong underwriting fit for 7(a) at Preferred Lender banks. Most established HVAC companies qualify at the non-bank or bank tier depending on seasonality smoothing.
HVAC companies have one of the most pronounced seasonal cash-flow patterns in the trades: 60-70% of annual revenue concentrates in Q2-Q3 cooling-season service + installation, with Q4-Q1 revenue dropping to maintenance-contract minimums. This shape drives specific financing needs: payroll smoothing through slow months, working capital to stock parts inventory ahead of peak season, equipment financing to buy or replace service trucks + recovery + diagnostic tools, and capital for expansion (second location, fleet expansion) when growth allows.
Equipment financing uses the equipment itself as the primary collateral, allowing lower rates (6-25% APR) and longer terms (24-84 months) than working-capital products. Common HVAC equipment purchases: service vans + trucks (often single biggest line item — $40K-$100K per vehicle), refrigerant recovery machines, charging/recovery systems, manifold gauges, leak detectors, brazing equipment, and diagnostic equipment for commercial systems. Section 179 deduction often applies — qualifying equipment fully expensed in the first year per IRS Publication 946. For trucks specifically, IRS Section 179 has separate thresholds for SUVs/vans vs heavy trucks.
The HVAC seasonal cash-flow pattern is a textbook line-of-credit use case: revolving access to capital you only pay interest on when you draw. Typical pattern: draw $15-50K in March-April to stock summer parts inventory + pre-pay supplier deposits → repay through May-September peak revenue → maintain a small draw through October-February for payroll smoothing → repeat. Non-bank lines price 18-35% APR; bank lines 8-16% for HVAC companies with 2+ years + 680+ FICO. See how does a business line of credit work.
HVAC is on the SBA Preferred Industry list under NAICS 2382 (Building Equipment Contractors). SBA 7(a) loans price 9-13% APR for HVAC operators at PLP banks. Common uses: buying out a partner, acquiring a second location, fleet expansion (multiple service vehicles), or owner-occupied commercial real estate (SBA 504 specifically for the property piece). The SBA 7(a) cap doubles to $10M effective July 4, 2026 — pulling in larger fleet + property deals previously sized out.
Most established HVAC companies (2+ years, $30K+/month average revenue) qualify at the non-bank tier (600+ FICO, $15K+/month average deposits) or bank tier (680+ FICO, 2+ years, profitable financials). Equipment financing on specific truck purchases is accessible even at lower FICO scores because the equipment is collateral. The Federal Reserve Small Business Credit Survey 2024 tracks approval rates across construction-adjacent trades — generally favorable for established operators with documented cash flow.
