Wrenmoor Funding, a small-business funding service in Chattanooga, TN, places requests from Hamilton County, TN plumbing, heating and air-conditioning contractors with funding partners. Typical requests cover service vans, parts and equipment stock, technician payroll and install jobs paid on progress terms; partners review job mix, deposits and quotes.
| Plumbing, heating and AC shops with a payroll (county) | 125 (CBP 2023) |
|---|---|
| Firms with one to four workers | 40.8% (CBP 2023) |
| Paid employees | 2,101 (CBP 2023) |
| Nonemployer businesses | 222 (NES 2024) |
Repair Tickets Pay Fast; Installs Pay Slow
Service and repair calls are usually paid on completion, by card or invoice within days. Replacement systems and new-construction installs are paid on a contract, sometimes with a deposit and a final payment after inspection. A shop with a growing install book can be short of cash precisely because it is winning work.
Parts and equipment add a third clock. Condensers, furnaces, water heaters and fittings are bought ahead and sit on shelves or in vans, and supplier terms rarely match customer terms.

By our arithmetic the county's 125 employer shops averaged about 16.8 employees each and $68,534 of payroll per employee in 2023, with bigger crews than the construction-wide average of about 13.7 employees. Only 40.8% had fewer than five employees, so many shops carry a sizeable technician payroll every week.
HVAC Business Loans for Vans and Equipment
Service vans, recovery machines, pipe threaders, jetters and camera kits are the usual equipment requests. They fit equipment financing, where the asset secures the deal and the term tracks its working life. Plumbing equipment financing works the same way. To test a payment before you shop, use the equipment finance calculator.
A two-van example (illustrative only)
A sample HVAC shop adds two upfitted vans at $58,000 each, with $11,000 down in total. The remaining $105,000 is the financed amount. Spread over a term that matches the vans' working life, the payment is set against the service revenue two more technicians can bill. Every figure in this example is made up.
Wage and Parts Gaps for HVAC and Plumbing Shops
Technician wages and parts orders do not wait for install payments. A line of credit covers recurring gaps between supplier invoices and customer payments; inventory financing suits a large stock order of units or fixtures ahead of demand. The longer article on working capital for HVAC and plumbing contractors works through the timing.
Service Agreements and Steady Revenue
Maintenance agreements bill on a schedule, so they show up in bank statements as regular deposits. Partners often read that recurring revenue favorably because it does not depend on new sales each month. Bring a list of active agreements and their billing cycle.
Parts on the Shelf Versus Parts on Order
Shops that stock common units and fittings win faster service calls but tie up cash; shops that order per job keep cash free but wait on suppliers. A shop may settle on a small core stock of fast-moving parts and order the rest. Funding follows that choice: a stocked shop leans on inventory financing or a line of credit, while an order-per-job shop mostly needs payroll cover between install payments.
Whichever model a shop runs, a parts list with turnover by item helps a partner see which stock really earns its shelf space.
A Rough-In Contract and Its Pay Applications (Illustrative Only)
A sample shop signs a $60,000 rough-in contract on a subdivision, billed by monthly pay application. The general contractor pays 45 days after each application and holds back 5% until the job is done. The first $20,000 application therefore brings in $19,000 about six weeks later, with $1,000 held, while the shop has already paid for pipe, fittings and two crews. The figures are made up; your contracts set the real terms.
New housing keeps this kind of work coming: Hamilton County, TN authorized 2,043 new residential units in 2023, 2,130 in 2024 and 1,887 in 2025 (Census Bureau Building Permits Survey). Rough-in schedules like this are often a line of credit question.
Part of the Construction Family
Plumbing and HVAC sit inside construction in the federal codes. The contractor and builder page covers draws and retainage in more depth, and the Chattanooga, TN page has the county figures. Other trades are on the industry index.
This page is about funding the contractor's own business. Homeowner financing for a new system is a different product and is not covered here.
