Pro tips for HVAC contractors

Equipment and parts are taxable while HVAC labor may be exempt depending on your state — separate equipment, parts, and labor lines.

HVAC invoice FAQ

What should an HVAC invoice include?

A diagnostic/service-call fee, itemized labor, equipment and parts with model numbers, any refrigerant, warranty terms, and your HVAC license number.

Should I sell maintenance agreements?

Yes — an annual maintenance agreement billed upfront smooths revenue and keeps customers loyal. List it as its own line with the included visits described.

How do I bill an HVAC installation?

Take a deposit to order equipment, then bill labor and equipment separately, with the balance due on system startup and customer sign-off.

Is HVAC labor taxable?

Equipment and parts are generally taxable; labor depends on your state and whether it's a repair or new install. Keep the lines separate to tax correctly.
