How to Use This Template
- 1
Split equipment and labor costs clearly on every HVAC invoice. A furnace replacement invoice should show the equipment cost (e.g., "Carrier Infinity 59MN7 furnace — \$3,200"), installation labor (e.g., "8 hours @ \$95/hr"), and any additional components (flue pipe, thermostat, filter) as separate line items. This transparency is especially important because HVAC equipment is a major purchase.
- 2
For maintenance contracts, invoice on a recurring schedule—monthly, quarterly, or semi-annually depending on the plan. Each invoice should reference the service agreement number, list the services included (filter change, coil cleaning, refrigerant check), and note the next scheduled service date. This reinforces the value of the contract and reduces cancellations.
- 3
List refrigerant charges separately with the type (R-410A, R-22), quantity in pounds, and per-pound cost. Refrigerant pricing varies significantly and clients often research prices online, so transparency prevents disputes. Note whether the charge includes a leak search or system test.
- 4
For system installations over \$5,000, offer financing options and note them on the invoice. Show the total cost, the financing terms (e.g., "60 months at 0% through GreenSky"), and the monthly payment amount. Many HVAC contractors lose deals because clients can’t pay the full amount upfront—financing makes the invoice feel manageable.
Frequently Asked Questions
How should HVAC contractors bill for equipment versus labor?
Always separate equipment and labor on your invoice. List each piece of equipment with the manufacturer, model number, SEER/AFUE rating, and cost. Then list labor as a separate section with hours and rates. This matches manufacturer warranty requirements and gives clients a clear breakdown of where their money goes.
When should I invoice for HVAC maintenance contracts?
Invoice at the beginning of each billing period (monthly, quarterly, or annually). For semi-annual tune-up plans, invoice before each scheduled visit. Include the service agreement number, covered services, and next visit date on every invoice. Auto-billing with a card on file reduces late payments significantly.
How do I handle warranty parts on an HVAC invoice?
Show the warranty part at its retail value with a line item credit or \$0 charge, then bill the labor separately. For example, "Compressor (warranty replacement) — \$0" and "Compressor installation labor — 4 hours @ \$95/hr." This documents the warranty claim and shows the client they’re only paying for labor.
What payment terms are standard for HVAC invoices?
For repairs under \$1,000, collect payment at the time of service. For system installations, a typical split is 50% deposit and 50% upon completion and inspection. Net 15 is standard for commercial HVAC work. Always offer multiple payment methods and consider financing for installations over \$5,000.
