Service truck loans for vans, box trucks, and utility upfits up to $80K+ each. Equipment loans for recovery machines, vacuum pumps, scan tools, and specialty diagnostic. Lines of credit for seasonal cash flow (HVAC has predictable cooling-rush/heating-rush cycles). SBA 7(a) for business acquisitions up to $5M. SBA 504 for owner-occupied shop/yard. Surety bonding through specialty brokers (Marsh, Aon, NFP) for commercial contracts. Specialty trades lenders (Live Oak Bank, Stearns Bank) understand HVAC seasonality and price more aggressively than general lenders.
HVAC contractors have predictable seasonal cash flow (cooling rush May-September, heating rush November-February) and a deep specialty financing ecosystem — service trucks, equipment, working capital, surety bonding, and SBA. This guide covers the products, the lenders that fit, and how to stack financing efficiently. For broader context see equipment financing and construction company financing guide.

Seasonal Working Capital
HVAC has the cleanest seasonal cash-flow pattern in U.S. SMB. Cooling-rush AR builds May-September; heating-rush AR builds November-February; shoulder seasons (March-April, October) require capital to make payroll and inventory the next rush. The right product is a line of credit, not a term loan or MCA:
- Bank line: 9-12% APR, 1-3 year facility, $50K-$1M typical limit
- Online line: 15-25% APR, available faster but materially more expensive
- Avoid: stacking MCAs — HVAC seasonality is so predictable that a line beats an MCA almost every time
Time the line setup ahead of the next rush so you have capacity when the season hits.
Service Trucks and Van Fleet
Service trucks are the largest equipment category for most HVAC contractors. Typical fleet decisions:
- Cargo vans (Ford Transit, Mercedes Sprinter, Ram ProMaster, GMC Savana): $40K-$60K base + $5K-$15K utility-body or shelving upfit
- Box trucks (Isuzu NPR, Hino, Ford F-650): $50K-$90K for service body
- Heavy service trucks (Kenworth/Peterbilt with crane and compressor): $100K-$200K+
Specialty truck/van lenders: National Funding, Stearns Bank, Crest Capital, plus OEM captives (Ford Pro, GM Envolve, Ram Commercial, Mercedes-Benz Sprinter financing).
HVAC Business Acquisitions
HVAC business acquisitions are very SBA-active. Representative $1.2M residential/light-commercial HVAC business purchase:
- SBA 7(a): $1.0M (83% of purchase). 10-year amort, 10.75% APR. Monthly P&I ~$13,700.
- Seller note: $120K (10% of purchase) on full standby for 24 months.
- Buyer equity: $80K (~7% cash) + standby seller note covers SBA equity requirement.
The lender will require: P&L showing seasonal pattern (3 years), tax returns, technician roster with EPA 608 certifications, recurring service contract list (high-margin maintenance contracts), warranty/service ratio, customer concentration analysis, and equipment list with values.
Specialty HVAC Lenders
- Live Oak Bank — deep trades and HVAC SBA book
- Newtek Small Business Finance — very active SBA 7(a) trades lender
- Stearns Bank — equipment-focused trades deals
- National Funding / Crest Capital / Direct Capital — specialty truck and equipment lenders
- Ford Pro / GM Envolve / Ram Commercial / Mercedes-Benz Sprinter financing — OEM van and truck captives
- Marsh / Aon / NFP / Hub International — surety brokers for commercial contractor bonding
AR Financing for Commercial HVAC
Contractors doing significant commercial work (large property managers, REITs, healthcare systems) sometimes use AR financing or factoring to bridge the slow-pay cycle. Commercial customers commonly pay 45-90 days. Specialty contractor-AR lenders factor signed contracts at 1-3% per month, useful as a complement to a bank line but rarely a permanent funding source.
