HVAC invoicing tips
- List part model numbers on the invoice. When a part fails under warranty, the model number is what makes the claim painless.
- Keep the diagnostic fee as its own line — and note when it is credited toward the repair. Customers accept diagnostics; they resent feeling tricked by them.
- Separate the parts warranty from your labor warranty. Manufacturers cover parts; you cover the workmanship, and the invoice should say for how long.
