The short answer

Writing down the model, the serial number and what you did makes warranty claims and next year’s visit much easier. Fill in the lines below, and print it or save the PDF.

How it works

What to record on an HVAC invoice

  • Equipment details: make, model and serial number
  • The problem and the fix, so the next tech doesn’t start over
  • Refrigerant: the type and amount added
  • Warranty: what’s covered, and for how long

Turn one-time customers into regulars with a service agreement covering spring and fall tune-ups. See also our guide to HVAC answering services.

Common questions

What should an HVAC invoice include?
Your business and license number, the customer, the equipment’s details, what you found and did, the diagnostic fee, parts, refrigerant, labor, the total and how to pay.
Should the diagnostic fee go toward the repair?
That’s up to you, and many companies credit it if the customer goes ahead. Whichever you choose, tell them before you start.
Should I list refrigerant separately?
Yes. It’s helpful to customers, and you may have records to keep for it. Show the type and amount.
Can I add a maintenance plan?
Yes, as its own line. Put the details in a service agreement.
Is this template free?
Yes. No sign-up and no watermark. It runs in your browser, so nothing you type is stored or sent to us. Print it or save it as a PDF before you close the page.
