Southwick Loans in Statesville, NC explains working capital for HVAC and plumbing companies in Iredell County: where the cash gap comes from, how to measure it, when a lump sum or a line of credit fits, and what partners review. County Business Patterns counted 72 plumbing, heating and air-conditioning contractor employers in the county in 2023, most with fewer than five employees.
Three drains on an HVAC bank balance
Three things pull cash out of an HVAC business ahead of revenue. Equipment for installs, often paid on delivery. A parts room stocked for service calls. And technician payroll, paid weekly regardless of when customers pay. Service calls may be paid at completion; installs for builders and property managers can take thirty days or more.
Plumbing contractors face the same shape, with water heaters and fixtures in place of condensers and coils, which is why business loans for plumbers follow similar logic.
Measure your own gap first
- List the next month's installs with equipment cost and expected payment date.
- Add a month of payroll and the parts you expect to restock.
- Subtract the service revenue you expect to collect in the same month.
- The difference, at its largest point, is roughly the working capital the month needs.
Working capital for an HVAC company has a clearer basis when it is sized from that calculation instead of a round number.
A lump sum or a line of credit?
If the gap comes from one large job or a one-time stock-up, a working capital lump sum repaid over a short term fits. If the gap repeats every month as installs roll through, a line of credit drawn and repaid with each cycle may suit better; compare the total dollar cost of each option. Many contractors who start with one end up with the other.
Business loans for HVAC companies beyond working capital
Vans, recovery machines and lifts are better on equipment financing, and a large pre-season equipment order can go on inventory financing. Keeping those separate stops a working capital line from being tied up by long-lived purchases. The plumbing and HVAC page sets out all four structures for these trades.
What partners look at for HVAC business financing
- Bank statements showing both service and install deposits
- Maintenance agreement counts, which show recurring revenue
- Supplier accounts and their payment terms
- Contracts with builders or property managers
- Existing van and equipment payments

An illustrative month, with invented figures
Not real data. An HVAC company books four installs worth $46,000, with $30,000 of equipment paid on delivery and payment due 30 days after completion. Payroll for the month is $22,000 and service calls bring in $25,000. At the low point the company is out roughly $27,000 before install payments arrive. That figure, not the install total, is what a working capital request should be sized against. The remaining Southwick posts are listed on the blog.
