Prairiebank Loans, a small-business funding service in Florence, AZ, walks through buying a plumbing or HVAC business in Pinal County, AZ: valuing service agreements, inspecting vans and equipment, keeping technicians, the license question, and how a purchase is usually funded with a term loan and equipment financing. Partners review and decide.
The market for plumbing and HVAC shops in Pinal County, AZ
Pinal County, AZ had 133 plumbing, heating and air-conditioning contractor employer establishments in 2023, and 78.2% of them had fewer than five employees (County Business Patterns 2023, NAICS 238220). Another 327 plumbing and HVAC businesses reported receipts but no payroll in 2024 (Nonemployer Statistics 2024, a broader code). Most employer shops in the county are small (78.2% had fewer than five employees, CBP 2023), so a shop for sale may be a few vans, a handful of technicians and an owner who still does much of the selling.
How to buy a plumbing business: what to look at first
- Revenue split: service calls, replacement installs, new construction and maintenance agreements.
- The agreement list: how many, what each pays, renewal rates and how many are transferable.
- Customer concentration: how much revenue comes from one builder or property manager.
- Vans and equipment: age, mileage, condition and any loans or leases still on them.
- People: which technicians are staying, and whether the owner holds the key relationships.
- The license and who will be the qualifying party after the sale.
Why service agreements carry so much weight
Maintenance agreements are recurring revenue that shows up as steady deposits, and they bring customers back for repairs and replacements. Partners reviewing business loans for plumbing contractors or HVAC companies often look at how many agreements there are, what they pay and how many renew each year. Ask the seller for the list with start dates and renewal history.
Plumbing equipment financing options in a purchase
Part of the price often goes to vans, jetters, cameras and recovery machines. Those can sometimes be financed separately with equipment financing, leaving the term loan to cover goodwill and the customer base. Check whether any vehicle has an existing lien that must be paid off at closing.
How the purchase is usually funded
A typical structure is a term loan for most of the price, equipment financing for the fleet, and the buyer's own cash. Some sellers carry part of the price on a note paid over time, which can make the deal easier to fund because the seller has a stake in a smooth handover. Partners commonly want the seller's tax returns and financials, the agreement list, the equipment list and the purchase agreement.
Keep a cushion for the first months. Customers and technicians sometimes test a new owner, and working capital for an HVAC business or plumbing company can carry payroll while the transition settles.
Questions for the seller's technicians
In a small trade shop, technicians can carry the customer relationships. Before closing, and with the seller's agreement, talk to the lead technicians about their plans and what would keep them. A buyer who knows the team is staying can present a much stronger case to a partner than one who is hoping it will.
Warranty callbacks you may inherit
A trade business has done hundreds of past jobs, and some of them still carry the company's labor warranty. After the sale, a customer with a failed install will call the name on the van, which is now yours.
- Ask the seller for a list of installs still under the company's own labor warranty.
- Ask how callbacks have been handled and roughly what they have cost.
- Agree in the purchase terms who pays for callbacks on work done before closing.
Callback cost is real cash after closing, so it belongs in the working capital cushion you plan alongside the purchase loan.
An illustrative purchase (invented figures, not an offer)
A buyer agrees to purchase a four-van HVAC company in Casa Grande, AZ. The price includes $120,000 for vans and equipment and $260,000 for the customer base and 410 maintenance agreements. The seller will stay for 90 days and carry a small note. A partner might look at equipment financing for the vans and a term loan for the rest, after reviewing the seller's records and the agreement renewal history. All amounts and terms would come from the partner.
The plumbing and HVAC funding page covers vans, parts and day-to-day cash; the Florence, AZ page has county figures. Three more Pinal County articles, on trades, landscaping and supplier terms, are on the Prairiebank blog.
