AvoHVAC Invoice Template (Free Fillable PDF)
HVAC invoices have two things other trades don't: refrigerant billed by weight and equipment with serial numbers that matter for warranty claims. This template has a line for each and keeps the diagnostic fee visible so it can be credited when the customer approves the repair.
Free, fillable, US Letter. No email, no sign-up. It works for a service call, a seasonal tune-up and a full system replacement, and the customer sees exactly where the money went.

Why HVAC invoices get paid late
Refrigerant charges questioned
“R-410A, 3 lb × $85” is understood. “Freon — $255” is googled and argued.
Diagnostic fee charged twice
Show the diagnostic fee and the credit on the same invoice when the repair is approved.
Serial numbers missing
Without the unit's model and serial on the invoice, the manufacturer warranty claim turns into a search through old photos.

Questions
How do I bill refrigerant on an HVAC invoice?
By type and weight: refrigerant type, pounds added, price per pound. Many states and the EPA expect the type and quantity recorded; it also justifies the number to the customer.
Should the diagnostic fee be credited?
Common practice is to credit it against the repair if the customer approves the work on the spot. Show both the fee and the credit so the invoice matches what was promised on the phone.
Why put model and serial numbers on the invoice?
Manufacturer warranty claims need them, and so does the next technician. One line per unit is enough.
What is a normal HVAC labor rate?
Varies widely: roughly $90–$180 per hour in the US depending on region and licensing, with many companies using flat-rate task pricing instead. Whichever you use, state it.
Can I use this template for a maintenance plan customer?
Yes. Add a line for the plan visit at the plan price and show the member discount on parts as a negative line, so the customer sees the value of the plan every visit.
