HVAC Invoice Template

An HVAC invoice template pre-filled with the line items HVAC techs actually bill: diagnostic, labor, equipment, and permit — with the math done for you.

Starts on the Modern style — steel blue and matter-of-fact, like the equipment it prices. Switch to any of the four included styles in one click.

No document caps, no watermarks. Your work autosaves in your browser and exports as PDF, JSON, or CSV.

Frequently asked questions

What should an HVAC invoice include?
Diagnostic/service call, labor hours, the equipment or unit cost if you installed one, and any permit fee — each broken out so the client can see the split between hardware and install.
Can I invoice a system replacement in stages?
Yes — issue a deposit invoice for part of the total up front, and a second invoice for the balance once the install is done; both can convert from the same accepted estimate.
Can I send a receipt once it’s paid?
Yes — record the payment on the invoice and issue a receipt for it in one step. The receipt names the invoice and payment it settles.
What if the job started as an estimate?
Convert the accepted estimate into an invoice in one step — the line items, numbering lineage, and design carry over. Start from the HVAC estimate template if you’re quoting first.
