If you run an HVAC or plumbing business, you know the seasonal reality: winter freeze and summer AC crunch keep you busy, but spring and fall can be painfully slow. Add the industry-standard practice of Net-30 to Net-60 invoicing, and you have a recipe for constant cash flow stress — even when your business is profitable on paper.
The HVAC/Plumbing Cash Flow Problem
Most HVAC and plumbing businesses share these financial characteristics:
- Seasonal revenue spikes — 60–70% of annual revenue comes in 4 peak months
- Slow-paying commercial clients — Property managers, property management companies, and commercial buildings often pay Net-45 or Net-60
- Constant equipment needs — Trucks, diagnostic tools, HVAC units, water heaters require ongoing capital
- Labor intensity — Technicians are salaried year-round but billable hours drop significantly in off-season
- Parts inventory — Need to stock common repair parts but can't predict exact demand
Best Financing Options for HVAC and Plumbing Contractors
Revenue-Based Financing
This is often the best fit for service businesses with seasonal revenue. Because repayments flex with your actual revenue, slow months don't crush your cash flow.
How it works: A lender advances you a lump sum (typically $10K – $250K). You repay through a set percentage of monthly revenue — say 10–15% of gross sales — until the advance plus factor fee is paid back.
Best use: Bridging cash flow gaps between peak seasons, purchasing inventory ahead of busy months, covering payroll in slow periods
Equipment Financing / Leasing
HVAC and plumbing companies need continuous equipment investment. Financing lets you spread the cost of trucks, diagnostic tools, refrigerants, and new units over time rather than draining cash reserves.
Leasing options: Operating lease (lower monthly payments, equipment returned at end) vs. finance lease (you're building equity in the equipment)
Best use: Fleet replacement, purchasing new diagnostic equipment, upgrading aging machinery
Invoice Financing (Factor Financing)
Commercial clients — property management companies especially — often take 45–90 days to pay. Invoice financing lets you get paid immediately on outstanding invoices.
How it works: You submit an invoice to the lender. The lender advances 80–90% of the invoice value within 24 hours. When your client pays, you receive the remaining 10–20% minus a factoring fee (typically 1–3%).
Best use: Large commercial jobs, property management contracts, government facilities work
Line of Credit
An unsecured business line of credit gives you flexible access to capital when you need it. Draw only what you need, pay interest only on what you use.
Best use: Emergency equipment repairs, covering payroll between jobs, purchasing parts inventory ahead of peak season
SBA Loans
For established HVAC/plumbing businesses (2+ years), SBA 7(a) loans offer long-term capital at competitive rates. Use for major purchases, truck fleets, or refinancing higher-cost debt.
Seasonal Financing Strategy
The smartest HVAC and plumbing contractors don't wait until they're cash-strapped to seek financing. Here's the optimal approach:
Before Peak Season (January–February)
Apply for and secure a line of credit or revenue-based financing facility BEFORE you need it. This is when lenders are most willing to extend credit because they can see your trailing revenue from the previous peak season.
Use the capital to stock up on parts, pre-purchase refrigerants at lower off-season prices, and ensure your fleet is in top shape before the rush.
During Peak Season (Summer/Winter)
Use financing to hire temporary technicians to handle the volume surge. The revenue from additional jobs more than covers the cost of the temporary labor.
After Peak Season (Fall/Spring)
This is when cash reserves typically run lowest. Revenue-based financing repayments are naturally lower because your revenue is lower — that's the benefit of flex payment structure.
How to Improve Your Financing Options
- Separate business and personal accounts — Clean financials make you more credible to lenders
- Document your commercial contracts — Property management agreements, service contracts, HOA relationships
- Build business credit — Open business credit accounts with suppliers and lenders who report to business credit bureaus
- Track job profitability — Know which types of jobs are most profitable so you can prioritize
- Reduce payment terms for discounts — Offering 2/10 Net-30 to commercial clients can speed up payment
