What belongs on a hvac technician invoice
Pressures and temperature split on the invoice turn "it's working now" into data — and make the next tech's job (probably yours) faster.
If the fee is waived with repair, show it: a line the customer watches disappear is worth more than a discount they never see.
The capacitor's price, the fitting, and the maintenance service are different purchases. Split them and the total explains itself.

HVAC technician invoicing questions
Is the diagnostic fee standard?
Yes — it covers the trip and the testing, and is commonly credited against the repair. Either way it appears on the invoice, so the policy is visible rather than discovered.
