Frequently asked questions

How do I write an HVAC estimate for a system replacement?

Start with the equipment (model, size, efficiency), then installation labor, materials such as line sets and pads, removal of the old unit, permits and warranty. Many techs add two or three options at different efficiency levels.

Should HVAC invoices show refrigerant separately?

Yes. Refrigerant is billed by the pound and prices change often, so a separate line keeps the invoice transparent and makes service calls easier to compare.

What must an invoice include?

A unique invoice number, the issue date, your business details, the customer's details, a description of the work, amounts, taxes, the total due and the payment terms.

What payment terms should I use?

Due on receipt, Net 14 and Net 30 are common. Shorter terms usually mean faster payment for small businesses.
