Frequently asked questions
What should an HVAC invoice include?
List the service address and the system you worked on, a diagnostic/service-call fee, labor hours and rate, and every part (refrigerant, capacitors, filters) as its own line. Add any maintenance plan or warranty and the next service date, then the total and terms.
How do I charge for emergency or after-hours calls?
State an after-hours multiplier — commonly 1.5× to 2× your standard labor rate — on the invoice and in your terms so customers know the charge up front. List the emergency rate as a separate labor line so the premium is transparent.
How should I invoice a maintenance contract?
Bill the annual or seasonal plan up front as a single line item, and note how many tune-up visits it covers and any member discount on repairs. Recurring maintenance invoicing smooths your cash flow and keeps customers on a schedule.
