HVAC invoices are more complex than most trades — you're dealing with equipment costs, refrigerant charges, warranty terms, and service agreements. A professional HVAC invoice captures all of this and protects both you and your client.
What to Include on an HVAC Invoice
- Your HVAC license number — required in all states for refrigerant handling
- Equipment details — make, model, and serial number of any installed or serviced equipment
- Refrigerant type and quantity — required for EPA compliance
- Itemized parts and labor — list every part separately with part numbers
- Warranty terms — manufacturer warranty on equipment plus your labor warranty
- Service agreement options — upsell annual maintenance plans on the invoice
- Payment terms — HVAC jobs are expensive; be clear about deposits and payment schedules
